. In the event of an error, the activity’s error variable is populated with the appropriate error schema. -Defined Process Variables You can define your own process variables and assign values to them in your process definition. Process variables are defined on the Process Variables tab of the Process Definition resource. You create a process variable in the same way you create data schemas for activities. Tibco Questions

All process variables in a running process instance are stored in memory and therefore consume system resources. Memory saving mode allows memory used by a process variable to be released when the value of the variable is no longer needed. When using memory saving mode, as each activity is executed, the list of process variables is evaluated to determine if subsequent activities in the process refer to the variable. If no activities refer to the variable, the memory used by the variable is released. A shared variable is a shared configuration resource in the General Activities palette. There are two types of shared variables: • •

Shared Variable Job Shared Variable

A Shared Variable resource allows you to share data across process instances. All process instances can read and update the data stored in a shared variable. This type of shared variable is useful if you wish to data across process instances or if you wish to make a common set of information available to all process instances. A Job Shared Variable resource is similar to a Shared Variable, but its scope is limited to the current job. A copy of the variable is created for each new process instance. This type of shared variable is useful for ing data to and from sub-processes without creating an input or output schema for the called process Q

What is the check point activity and confirm activity

If the checkpoint is done before the confirm activity and a crash occurs before confirm and after checkpoint then the original message can be resent since a new process instance could be created. Where as if the confirm activity is before the checkpoint and the crash happens after the confirm and before checkpoint then the message is confirmed and cannot be redelivered. Since process instance cannot recover the confirmed message. Q What types of actions you can have in the group and explain them with examples? Groups are used to specify related sets of activities. Grouping allows you to create loops. The main uses of groups are the following: • Create a set of activities with only one condition for the group. This allows instead of trying to individually catch errors on each activity. This type of group is similar to a try...catch block in Java. • Create sets of activities that are to be repeated. You can repeat the activities once for each item in a list, until a condition is true, or if an error occurs. Tibco Questions

• Create sets of activities that participate in a transaction. Activities within the group that can take part in a transaction are processed together or rolled back, depending upon whether the transaction commits or rolls back. Q What are the different kinds of condition types you can have in transition? Explain Them Success /Success with condition/Success if no matching condition/error Q

What is spawn process explain Spawn: Specifies whether to spawn a new machine process for executing the called process. If this option is checked, the parent process cannot access the called process’ output. The called process is executed in a separate process instance.

Q

Xml Parser, Xml Render and XML Transform activities The Parse XML activity takes a binary XML file or an XML string and processes it, turning it into an XML schema tree based on the XSD or DTD specified. The preferred way to parse XML files is to use a Read File activity set to binary mode to read the XML file. Then the binary file contents to the Parse XML activity. The Render XML activity takes an instance of an XML schema element and renders it as a stream of bytes containing XML or an XML string. The schema is processed based on the XSD file specified. The Transform XML activity allows you to transform an input XML document into the output specified by the given XSLT File shared configuration resource. Normally, transformation of data occurs by mapping process variables to an activity’s input and applying XPath expressions to perform any transformation. If you have an XSLT file that you are using for transformations, or if an outside source supplies an XSLT file, this activity allows you to use the XSLT file instead of manually creating the mappings.

These files are shared resources that describe web services.

Compare the OnStartup and onShutdown activities The On Startup process starter specifies a process to execute when the process engine starts, before any incoming events are processed. In the event that the process engine is restarting and attempting to recover checkpointed process instances, the On Startup process definition must complete its execution before any recovered process instances execute. The On Startup process starter can be useful to specify any preprocessing that must be done before regular processing starts. For example, your application may check that the required database tables exist and create them necessary. Also, you may wish to send email to s notifying them that the process engine is starting. Typically, you create one process definition that uses the On Startup process starter and place all pre-processing activities into that process definition. However, you can have more than one process definition that uses the On Startup process starter. All process definitions with

the On Startup process starter execute in no specific order when the process engine starts. The On Shutdown process starter specifies a process to execute when the process engine shuts down, after all process instances are executed. The On Shutdown process starter can be useful for specifying any postprocessing that must be done before shutting down the engine. For example, your application may back up a database table then purge the data. Also, you may wish to send email to s notifying them that the process engine is shutting down. Typically, you create one process definition that uses the On Shutdown process starter and place all post-processing activities into that process definition. However, you can have more than one process definition that uses the On Shutdown process starter. All process definitions with the On Shutdown process starter execute in no specific order when the process engine shuts down Q

Compare Timer and Sleep Activities The Sleep activity suspends the process on the current transition for the given amount of time. If you have multiple control flows in your process, only the current execution branch of the process is suspended. The Timer process starter starts a process at a specific time. You can also specify that processes are to be started periodically.

Q

Transaction Palette Transactions allow you to perform a group of activities as a single unit of work. All activities in the group either complete or commit together or one or more failures in the group cause the transaction to roll back or undo the changes made • JTA Transaction Configuration • Transaction State • XA TransactionManager Configuration The JTA Transaction Configuration shared configuration resource contains the information required to communicate with a Java Transaction API (JTA) transaction manager. This resource is used by transaction groups that use the JTA Transaction type The Transaction State activity can be used in a transaction group to obtain the current state of the transaction or to set the transaction to a rollback only state. When a transaction is set to the rollback only state, the only outcome of the transaction that is permitted is a rollback.

The XA TransactionManager Configuration shared configuration resource contains the information required to communicate with an XA-compliant transaction manager. This resource is used by transaction groups that use the XA Transaction type Q

Inter process communication

Executing process instances can communicate and can data between each other. The General Activities palette contains the Wait and Notify activities and the Receive Notification process starter for implementing interprocess communication. TIBCO BusinessWorks allows two executing process instances to communicate. You may need process instances to communicate if you wish to synchronize process execution or if your processes must execute in a specific order. TIBCO BusinessWorks provides the Wait and Notify activities and the Receive Notification process starter to handle inter-process communication. These activities are similar to semaphores in programming. A process containing a Wait activity waits for another process to execute a corresponding Notify activity. Alternatively, the Receive Notification process starter creates a new process instance when another process executes the corresponding Notify activity. The data sent between the activities is defined by a Notify Configuration shared configuration resource. The Notify activity only sends information to the Receive Notification process starter or Wait activity that specifies the same Notify Configuration resource. The schema supplied to the Notify Configuration resource can be empty, if you do not wish data to be sent between processes. However, the Notify Configuration resources must be the same for the Notify, Receive Notification, or Wait activities if they are to be used to communicate with each other. A string-based key is used to coordinate between Wait/Notify/Receive Notification activities to determine when a Notify activity corresponds to a Wait or Receive Notification. The key is supplied to the Notify activity, and any Wait activity that matches that key is executed when the Notify occurs. When a Notify activity executes its information is stored until a matching Receive Notification or Wait activity accepts the information. The Notify activity executes immediately and transitions to the next activity. The Notify activity cannot be used to determine when a corresponding Receive Notification or Wait has received the information. In general, using inter-process communication consists of these steps: 1. Define the data that must be ed between the processes by creating a Notify Configuration shared configuration resource. 2. Determine the key that correlates processes with Notify activities with the corresponding processes with Receive Notification process starters or Wait activities. Tibco Questions

Start an application’s process engines or service instances Stop a successfully deployed process engine or service instance. Monitoring and Management Options? At runtime, TIBCO allows you to remotely access all deployments in your istration domain. Depending on your security privileges, you may be able to perform one or more of the following tasks. • Management—Add s and s to the istration domain for authentication, then give each view or execute privileges for TIBCO GUI elements or project repositories (data stores). • Domain Monitoring and Management—View the status of machines and components running on machines in the domain. Start and stop components as needed. • Deployment monitoring—Monitor the status of each deployment component (process engine and adapter) and process instance and the status of the machines executing them. View trace files and throughput. • Deployment management—View all running components and stop and restart them as needed. These aspects of monitoring and management are ed by TIBCO , which includes the TIBCO istration Server and the TIBCO GUI. Tibco Hawk TIBCO Hawk is a sophisticated tool for enterprise-wide monitoring and managing of all distributed applications and systems. System s can use it to monitor adapters in a wide area network of any size. TIBCO Hawk can be configured to monitor system and adapter parameters and to take actions when predefined conditions occur. These actions include: sending alarms that are graphically displayed in the TIBCO Hawk display, sending email, paging, running executables, or modifying the behavior of a managed adapter. Unlike other monitoring applications, TIBCO Hawk relies on a purely distributed intelligent agent architecture using publish or subscribe to

distribute alerts. TIBCO Hawk uses TIBCO Rendezvous for all messaging and thus gains the benefits and scalability from the TIBCO Rendezvous features of publish/subscribe, subject name addressing, interest-based routing, and reliable multicast. TIBCO Hawk is a purely event-based system that uses alerts. The agents are configured with rules that instruct them on everything from what and how to monitor to what actions to take when problems are discovered. Thus the workload is fully distributed throughout the enterprise. Every agent is autonomous in that it does not depend on other components to perform its functions. The TIBCO Hawk Enterprise Monitor consists of these components: • Display—GUI front end that displays alarms and provides editors to create rule bases, create tests, view messages, and invoke microagents to request information or initiate an action. • Agents—Intelligent processes that perform monitoring and take actions as defined in rules. • Rulebases—Rules that are loaded by agents to determine agent behavior. • Application Management Interface (AMI)—Manages network applications via TIBCO Rendezvous and s communication between a network application and monitoring TIBCO Hawk agents, including the ability to examine application variables, invoke methods, and monitor system performance. • Microagents—Feed information back to TIBCO Hawk and expose action methods to rulebases. Available Microagents Each adapter has two microagents, a standard TIBCO Hawk microagent named COM.TIBCO.ADAPTER.xyz (where xyz is the adapter configuration name) and a custom microagent. These microagents provide: • Business level statistics—statistics that report the progress of the adapter as it interacts with the database. For example, in a database adapter such statistics might indicate whether objects were successfully or unsuccessfully inserted, updated, or deleted in the database. • Queries that return information about the state of the adapter. This can be an important tool for seeing the internals of an adapter and debugging it if something appears wrong. For example, methods can return information about threads, internal queues, or connections to the target system. Using these methods, one might be able to identify certain bottlenecks or gauge how successfully an adapter is scaling with respect to the current environment. • Updates of the adapter runtime parameters. This includes retrieving the current runtime parameters and setting new runtime parameters without restarting the adapter. An example of this is getting and setting the polling interval. Updating a runtime parameter through the Hawk microagent only affects the setting of the instance that is Tibco Questions

running. It does not make a permanent change of the setting in either the repository or the .tra file. Q Rulebase A rulebase is a collection of one or more rules. A rule is a defined monitoring policy. It specifies a data source in the form of a microagent method, one or more tests that check for conditions, and one or actions to perform if a test is true. With TIBCO Hawk rulebases, you can perform general monitoring tasks and test for very specific conditions. Escalations can be applied to actions to allow for a staged response to a condition. An agent can be configured to initially take corrective actions itself, but if the condition still persists, then call for outside help from s. The rulebase editor in TIBCO Hawk Display allows easy construction of simple and complex rules. No scripting is required and an does not need to learn special rule syntax. The rules of a rulebase are typically constructed so that each rulebase focuses on monitoring a particular application or system resource. The rulebases are then assigned to multiple agents with similar monitoring requirements. Configuration options provide flexible mechanisms for distributing rules. Adding a new rulebase to one agent or 1000 agents takes the same amount of time. All rulebase changes are performed dynamically in the agent with no required restart. Schedules can be imposed on the rulebase hierarchy to control when monitoring activity and corrective tasks are performed. In a schedule you can define both inclusion and exclusion periods during which an object can be active. Like rules, schedules can be distributed to multiple agents with similar requirements Q

Tibco Questions

An adapter provides a bridge between an application and your TIBCO integration environment Adapters are responsible for making information from different applications available to other applications across an enterprise. To do so, an adapter is configured to provide one or more of the following services: • Publication Service • Subscription Service • Request-Response Service • Request-Response Invocation Service Publication Service An adapter publication service recognizes when business events happen in a vendor application, and asynchronously sends out the event data in realtime to interested systems in the TIBCO environment. For example, an adapter can publish an event each time a new customer is added to an application. Other applications that receive the event can then update their records just as the original application did. As shown in the next diagram, when an application receives a request to create a new customer record, the application notifies the adapter about the request and the adapter publishes the event.

The following steps correspond to steps listed in the diagram: 1. Using a graphical interface, a new customer record is created in the application. 2. The application sends the new customer record to the adapter. 3. The adapter publishes the event using TIBCO messaging. Subscription Service Tibco Questions


19

An adapter subscription service asynchronously performs an action—such as updating business objects or invoking native APIs—on a vendor application. The adapter service listens to external business events, which trigger the appropriate action. Going back to the previous example, an adapter subscription service can listen for customer record creation events (happening in an application and published to the TIBCO infrastructure) and update another application. TIBCO Messaging Application Order Entry GUI 1) Create Customer Record 2) Generate Event 3) Publish Event Adapter

The following steps correspond to the new steps listed in the diagram: 4. The adapter is configured to listen to customer record creation events as they are published. 5. Upon reception of a customer creation event, the adapter updates the application to which it is connected. Request-Response Service In addition to asynchronously publishing and subscribing to events, an adapter can be used to synchronously retrieve data from or execute transactions within a vendor application. After the action is performed in the vendor application, the adapter service sends a response back to the requester with either the results of the action or a confirmation that the action occurred. This entire process is called request-response, and it is useful for actions such as adding or deleting business objects. Tibco Questions


20

In the next example, an adapter receives a request message from the TIBCO infrastructure and sends it to an application. The adapter gets a response from the application and returns it. TIBCO Messaging

The following steps correspond to steps listed in the diagram: 1. An application sends a message request to the TIBCO environment. 2. The adapter, acting as a request-response server receives the request and forwards the request to the application. 3. The application parses the request and returns a response message to the adapter. 4. The adapter sends the response message back to the TIBCO infrastructure where the response is available to the requesting application. Request-Response Invocation Service An adapter request-response invocation service is similar to the requestresponse service, except that the roles are reversed. The vendor application is now the requester or initiator of the service, instead of the provider of the service. The adapter service acts as a proxy, giving the vendor application the ability to synchronously invoke functionality on an external system. The next diagram shows the adapter sending a request message from application Y to application X. After it processes the message, it is returned to the adapter, which sends the response back to application Y. TIBCO Messaging

Q What are the possible transports between adapters and Business process? TIBCO Rendezvous Reliable and Certified Message Delivery Modes ActiveEnterprise Message/Rendezvous Message/XML Message wire formats Possible values are: • Reliable (TIBCO Rendezvous transport type only) Reliable message delivery. Ensures that each multicast or broadcast message is received as long as the physical network and packet recipients are working, and that the loss of a message is detected. This choice can compensate for brief network failures because it can retransmit a message on request if the first attempt failed. This choice is appropriate when message delivery is expected but some loss can be tolerated. Messages are received without explicit confirmation. • Certified (TIBCO Rendezvous transport type only) Certified message delivery. Offers stronger assurances of message receipt, along with tighter control, greater flexibility and fine-grained reporting. Guarantees that every certified message reaches its intended recipient in the order sent. The message can be sent across network boundaries, and if a network fails, delivery attempts continue until delivery succeeds or Tibco Questions


22

until the message's time limit expires. If certified message delivery is used, data is stored in a ledger file. The size of the ledger depends on several factors, the most important of which is the retention rate of stored data. That is, the ledger grows fastest in response to the cumulative length of undeliverable messages. You must ensure that sufficient disk space is available for the expected size of the ledger. TIBCO Enterprise for JMS Point to Point and Broadcast Delivery modes (persistent/non persistent) XML Message wire format • Persistent In general, a message marked persistent will be available to a JMS client even if the TIBCO Enterprise Message Service server goes down. Persistent messages are held in secondary storage in the server and have guaranteed delivery when sent to a topic that has durable subscribers. (If a topic has no durable subscribers, there are no subscribers that need messages resent in the event of a server failure and therefore messages do not need to be saved.) Performance is improved because disk I/O is not required. • Non-Persistent (JMS transport type only) A message marked non persistent will not be available to a JMS client if the TIBCO Enterprise Message Service server goes down. These messages are never written to persistent storage. Opaque transport uses the TIBCO Rendezvous wire format. Q What are the qualities of services we can have in adapter publishing services? The transport type (Rendezvous or JMS) you select for the run-time adapter determines which quality of service, delivery mode, and wire format the service can use. Only options that are compatible with a service’s transport type will be available for selection. Quality of service, delivery mode, and wire formats are described below. Quality of Service This is the level of service that determines how messages are sent. Possible values are: • Reliable (TIBCO Rendezvous transport type only) Reliable message delivery. Ensures that each multicast or broadcast message is received as long as the physical network and packet recipients are working, and that the loss of a message is detected. This choice can compensate for brief network failures because it can retransmit a message on request if the first attempt failed. This choice is appropriate when message delivery Tibco Questions

is expected but some loss can be tolerated. Messages are received without explicit confirmation. • Certified (TIBCO Rendezvous transport type only) Certified message delivery. Offers stronger assurances of message receipt, along with tighter control, greater flexibility and fine-grained reporting. Guarantees that every certified message reaches its intended recipient in the order sent. The message can be sent across network boundaries, and if a network fails, delivery attempts continue until delivery succeeds or until the message's time limit expires. If certified message delivery is used, data is stored in a ledger file. The size of the ledger depends on several factors, the most important of which is the retention rate of stored data. That is, the ledger grows fastest in response to the cumulative length of undeliverable messages. You must ensure that sufficient disk space is available for the expected size of the ledger. • Distributed Queue (TIBCO Rendezvous transport type only) A distributed queue is a group of cooperating transport objects, each in a separate process. To obtain load balancing among servers, the adapter uses distributed queues for one-of-n delivery of messages to a group of servers. Each member of a distributed queue listens for the same subject using the TIBCO Rendezvous Distributed Queue listener objects. Even though many listen for each inbound message (or task), only one member processes the message. • Transactional The Transactional option is no longer ed. The option is included for backward compatibility with version 5.0 and 4.x adapters Delivery Mode (JMS transport type only) The method of delivery for a JMS message. The semantics for these fields are somewhat more complex than the explanation given here. • Persistent In general, a message marked persistent will be available to a JMS client even if the TIBCO Enterprise Message Service server goes down. Persistent messages are held in secondary storage in the server and have guaranteed delivery when sent to a topic that has durable subscribers. (If a topic has no durable subscribers, there are no subscribers that need messages resent in the event of a server failure and therefore messages do not need to be saved.) Performance is improved because disk I/O is not required. • Non-Persistent (JMS transport type only) A message marked non persistent will not be available to a JMS client if the TIBCO Enterprise Message Service server goes down. These messages are never written to persistent storage. Wire Formats Services must use the same wire format to exchange data. • Rendezvous Message (TIBCO Rendezvous transport type only) A selfdescribing wire format used by TIBCO Rendezvous applications. Control Tibco Questions


24

information for validation is not sent in the message. If you use this format, the adapter is compatible with adapters not developed with TIBCO Adapter SDK. • XML Message (TIBCO Rendezvous and JMS transport types) The Transactional option is no longer ed. The option is included for backward compatibility with version 5.0 and 4.x adapters. The XML Message wire format conforms to specifically constructed and fully compliant XML Schema (XSD) based on the existing definition of the TIBCO ActiveEnterprise schema. • ActiveEnterprise Message (TIBCO Rendezvous transport type only) An externally-described XML wire format ed by the TIBCO Adapter SDK. Control information for validation is sent in the message. If no control information is included, an exception is returned to the subscriber. TIBCO ActiveEnterprise standard wire format provides class information and packing rules for the TIBCO Adapter SDK set of data types. This format allows TIBCO ActiveEnterprise components to perform extra validation on messages sent or received. Q

Explain the internal functioning of ADB publication service

Polling Mechanism Polling is a mechanism used by adapters to periodically retrieve data from a vendor application that stores data in a permanent store like a database. The settings for the polling interval and polling size can affect adapter performance. Setting too small of a polling size or too large of a polling interval can slow the your adapter’s performance if the vendor application itself is relatively fast. Conversely, setting the polling interval to be too small can create too much of a load on the vendor application. Definitions • Event data — Changes to application data that are stored as events in a permanent store. An example of a store is a database. The event data may be in the form of database records or reference keys that are used to retrieve actual data by invoking application API(s). • Event store or Publishing Table — The permanent store containing event data. The event store is also known in many adapters as a Publishing Table, or a Staging table. The event store may either be populated by setting triggers or ing callbacks within the application or by an adapter agent that is notified by the application of event data. The changes to application data are written (as actual data or reference to data) into the event store by plug-ins or triggers setup in the application instance during adapter configuration. • Publication Service — The adapter component that polls event data from the event store and publishes them to the TIBCO environment on the configured subject for that event type. • Poller— Component of the publication service that polls for the event data from the event store. How the Polling Mechanism Works Tibco Questions


25

The publication service in the adapter retrieves data from the store and publishes the desired information about the event in the TIBCO environment. For example, when an application updates a table in a database monitored by an adapter such as TIBCO Adapter for ActiveDatabase, the adapter extracts data from the changed rows from database tables and publishes them on appropriate subjects. An adapter polls (checks/selects) the publishing tables periodically for any new rows to be published. This method is most efficient when the publishing tables change frequently and a limited number of database operations is preferred. In the case where the publishing tables change infrequently, polling may result in many unnecessary database accesses. For this situation the alerter can be used to asynchronously alert the adapter of changes in the database. This removes the need for the adapter to poll its publishing table for existence of new rows. It is recommended to use the alerter only when database changes are infrequent. When the adapter receives an alert, it publishes the new data. The alerter is not available on all databases and platforms. Q What is publish by value and publish by reference. Explain the pros and cons. — Publish data by creating a copy (by value). — Publish by reference (publish data directly from the source database table without first copying the data from the source table to a publishing table). Publish by Value When a modifies a row in a source table that has been set up for publication, the data in the modified row is copied into a publishing table by a stored procedure created by the adapter during configuration. The adapter then selects the data from the publishing table, packs it into a message, and sends it. An advantage of publish by value is its speed. However, it does not some data types, such as Oracle LONG and LONG RAW. Publishing these data types by value from a top-level table is uned due to database trigger limitations. Publish by Reference The publish by reference feature allows you to publish data directly from the source table without first copying the data to a publishing table. If a source table is set up to publish by reference, the publishing table does not contain a copy of the source table data. Instead, the adapter selects the data for publishing directly from the source table itself. For example, to publish from ORDER_TABLE with a key field ORDER_ID, the publishing table is created with the necessary adapter fields and the ORDER_ID field. When a row in ORDER_TABLE is modified, the trigger fires, populating adapter fields and copying the ORDER_ID value to the publishing table. When the adapter polls the publishing table, it detects the new row Tibco Questions


26

and selects from the ORDER_TABLE using the ORDER_ID value found in the publishing table. Then the message is published. The advantage of publishing by reference is that the data to be published is stored just once. Also, this method s data types such as Oracle LONG and LONG RAW. The disadvantage of publish by reference is that after a row in the source table is modified, a small amount of time es before the adapter selects the row. During this short interval, the row could be modified again. If this happens, the adapter will get only the second set of modifications when it selects the row. However, this time lapse can be minimized by using the alerter. When publishing by reference, a key column or substitute key column is required for populating the publishing table. If the source table has no primary key, it can only be set up to publish by reference if a key column is specified when adding the publication. Q

What is Exception table You can designate an exception table for a subscription service. If a subscriber adapter cannot write data to its destination table, it will write the data to the exception table. To write to an exception table, an adapter must be started with the adb.useExceptTable option set to on in the supplied properties file and an exception table must have been specified when using TIBCO Designer to add a subscription. If an error occurs when inserting data into the destination table, the adapter attempts to insert the data into the exception table. • If the insertion into the exception table is successful and the RVCM quality of service is specified for the subscription, the transaction commits and confirmation for the message is sent back. In the publishing table, the value of the delivery status column is C, since the message was processed. If you are using a durable JMS subscriber, a JMS confirmation will be sent back. • If the insertion into the exception table fails, an error message displays, a rollback occurs and a TIBCO Hawk alert is published. The adapter will then terminate. The is advised to fix the problem with the message or the table and then to restart the adapter. The message will be delivered again after the adapter starts. (If the adapter did not terminate, after the next message was inserted successfully, its confirmation would also implicitly confirm the failed message.) You can identify the operation that failed by checking the ADB_OPCODE column of the publishing table. The ADB_ERROR_TEXT column contains error information. Using an Exception Table as a Source Table If you want to publish from an exception table and also want to use that exception table as the source table, do not use the

Tibco Questions


27

ADB_ERROR_TEXT or ADB_OPCODE column names. Instead, follow these guidelines: • Create a database view that mirrors the exception table, but rename the ADB_ERROR_TEXT and ADB_OPCODE columns so that they do not begin with "ADB_." • After renaming the columns, use Publish By Reference Object and choose your view as the reference object. Q

What is Opaque Exception table Use Opaque Exceptions Table Select the box to use an opaque exceptions table. The table records each message (entirely) into a column, along with the error message. A message is logged in the exceptions table if the subscription service fails to generate records in the destination table or the adapter fails to insert a message into an exception table. For DB2/OS390 databases, you must create a Large Objects (LOB) tablespace before using the opaque exceptions table, which will use the LOB tablespace. Opaque Exceptions Table Type the name for the opaque exceptions table. The subscription service uses two logical layers when processing a message. The first layer decodes data from the message and the second layer provides the database transaction. If an exception occurs in the first layer, the adapter logs the message to the opaque exception table. In the second layer, if any DML command fails at any level, the adapter rolls back this transaction and starts another transaction, inserting into exception tables. If the insert into exception table transaction fails, the adapter then logs the message to the opaque exception table. The opaque exception table records the entire message into a column along with the error message.

Q

Publication and subscription service Publication and Subscription Services The following diagram illustrates publication and subscription. Database Application 1 updates a table in a database monitored by a TIBCO Adapter for ActiveDatabase publication service. The adapter extracts data from the changed rows of the database tables and publishes it on the specified transport (TIBCO Rendezvous or TIBCO Enterprise Message Service). This data is then available to other applications listening on these transports. One particular type of listening application could be another instance of a TIBCO Adapter for ActiveDatabase adapter, running a subscription service. Upon receiving a message, it updates the relevant tables in its associated database.

Request-Response Service The request-response feature in TIBCO Adapter for ActiveDatabase allows an application to submit one or more SQL statements, stored procedures, or both for the adapter to execute. After execution, the adapter returns one or more result sets and a result code. The request and responses are formulated using nested self-describing messages. This data flow is illustrated in the figure below.

Tibco Q What are steps to follow to deploy a project in the Tibco or any other build scripts Q How will configure the Fault tolerant and Load Balancing in

In the diagram above, you see four EMS Server instances with each FaultTolerant (FT) pair sharing the same EMS “Server Name”, and you see the client with a complex URL that is constructed such that you have FT pairs separated by a comma and those pairs in a Load-Balanced (LB) arrangement separated by a vertical bar (or pipe symbol). To make this arrangement work on a single machine, the individual services are on distinct ports. The first FT pair has an active server on port 7222 with a backup server listening on port 7224, for example. The primary is the one that starts first. To make LB work, you need to route between servers, so a new EMS “Server Name” needs to be used, and Topics and Queues need to be routed between these instances. Queues are restricted to a single hop, while Topics can be Tibco Questions


30

multi-hop for their routes. Load-Balancing can be across an arbitrary number of servers and need not be in conjunction with Fault-Tolerance. Overall, we will be configuring the EMS Daemons, configuring appropriate JMS Factories, configuring routes, and creating Topics and Queues. Q Give the flow of client/Auto acknowledge modes for message delivery (RV or JMS) Q How to handle the System and Data errors in your Error handler part Q When you go for Java code in your project You can add custom code to your process definition with the Java Code activity. This activity allows you to write standard Java code that can manipulate any of the process data or perform any action you choose. The Java Code activity automatically creates an invoke() method in which you place the code you wish to execute. This method is called when the engine processes the Java Code activity. Accumulate Output For iteration and repeat until true loops, you can accumulate the output of one of the activities in a group by checking the Accumulate Output field. If you check this field, you can select one of the activities in the group, and each time the loop is executed, the selected activity’s output is placed into a list. The list of accumulated output for that activity is stored in a variable whose name is specified in the Output Name field. After the loop exits, this variable can be accessed in the same way other process data can be accessed by other activities. Because you can accumulate output from only one activity in a group, you should design your group so that only one activity in the group holds the data to accumulate for each iteration. For example, you may want to accumulate a list of customer names from repeated executions of a JDBC Database Query task, or you may wish to accumulate the sum of the amounts for line items in an order. Because you can only select one activity in the Accumulate Output field, to accumulate ouptut from several activities, you must use a different approach. One approach is to create a process variable to hold the data and use the Assign activity to assign values from each iteration of the loop to the process variable. Alternatively, you can use a Java Code activity to concatenate the data into the output parameters for the Java Code activity. You can then choose the Java Code activity as the Output Activity to accumulate for each iteration of the loop. Q. Persistent Connection pool Tibco Questions


31

You can specify the maximum number of connections to create in the persistent connection pool, and you can also specify the maximum number of persistent connections for each HTTP server. Connections for each HTTP server are created in the pool until the maximum is reached. When a Send HTTP Request activity requires a connection, the pool is searched for a connection that corresponds to the HTTP server. If a corresponding unused connection is found, it is used. If the maximum number of connections for that particular server have been reached, the request must wait for a connection to be released before using it. If no connection is found to a corresponding HTTP server, a new connection is created if the maximum pool size has not been reached. If no corresponding connection is found and the maximum pool size has been reached, the activity must wait for a connection to be freed before proceeding. Fetching Subsets of the Result Set When the result set of a query is very large, you can retrieve subsets of the result set and iterate until the entire result set is processed. To retrieve subsets, you must use a Repeat Until True loop group to iterate until the entire result set is processed. Use the following procedure as a guideline for creating your Repeat Until True loop group. 1. Create a JDBC Query activity. 2. Specify the fields on the Configuration tab and create a query that returns multiple rows. 3. Check the Process In Subsets field on the Advanced tab. 4. Set the subsetSize input item for the JDBC Query activity to the number of records you wish to process for each execution of the loop. You could specify a constant, or you could use a global variable to store the value. Using a global variable has the advantage that you can change the value of the variable at deployment time. For example, create a global variable named BATCH_SIZE, then specify the chunkSize input element as $_globalVariables/pfx:GlobalVariables/BATCH_SIZE. 5. Select the JDBC Query activity and click the group icon on the toolbar to create a group containing the activity. See TIBCO BusinessWorks Process Design Guide for more information about working with groups. 6. Select Repeat Until True as the Group action, and specify an index name (for example, i). 7. The loop should exit when the entire result set has been consumed. The output element lasSubset is a boolean that is set to true when the last subset of records is being processes. For example, the condition for the loop could be set to the following: $JDBCQuery/resultSet/lastSubset = "true" Tibco Questions


32

timeout number Time (in seconds) to wait for the query to complete. If the query does not complete in the given time limit, an error is returned. maxRows number The maximum number of rows to retrieve. To retrieve all rows, specify 0. Input Item Datatype Description Service Resource To define a Service resource, follow this general procedure: 1. Provide an abstract WSDL file (see WSDL on page 650) that describes the interface to the service. 2. For each operation in the interface, specify a process definition that implements the operation. 3. Specify one or more endpoint bindings to expose the service to potential clients. 4. For each endpoint binding, specify a transport configuration (either HTTP Connection or JMS Connection. 5. Specify any transport-specific information, such as endpoint URL for HTTP transports or JMS Destination Name for JMS transports. 6. Specify any SOAP details, such as SOAP Version or encoding for each operation. 7. Specify attachments, headers, or context information for input and output messages, if necessary.

Business Process Modeling Most businesses choose the best application or environment for processing each component of their core business. In a typical enterprise, the flow of information and processing between each application is what drives the dayto-day operations of the business. Q Loop Detection If a source table is used both as the source and destination table on the same subject, the loop detection feature should be enabled. The feature prevents the same changes from being published repeatedly. If the loop detection feature is enabled, an additional column, ADB_SOURCE, is added to the source table. When an adapter receives a message, it inserts or updates the source table and enters a T in the ADB_SOURCE column to denote that this row was inserted or updated as a result of a message, rather than from intervention. Triggers created by the ActiveDatabase Adapter Configuration palette are defined to not copy rows with T in the ADB_SOURCE column into the publishing table, which effectively means that the row will not be published. If you must update a row that was received (that is, has a T in the ADB_SOURCE column) and want the updated row propagated, you must also change the ADB_SOURCE column to NULL. This causes the trigger to pick up the row and send it out. Tibco Questions


33

Q Adapters Concepts Tables The tables are created by running a script specific to your database vendor. The script creates the following tables, all with a common set of columns: • Source table to which you will add new data. • Publishing table to which the new data from the source table is copied using the trigger set on the source table. This table has additional columns (prefixed by ADB_) that are used by the adapter. • Destination table that TIBCO Adapter for ActiveDatabase will update with the new data. • Exception table to which TIBCO Adapter for ActiveDatabase will write any errors that occur during subscription. Actions When you add data to the source table, the following occurs: 1. The insert action fires a trigger and the inserted row is copied to the publishing table. 2. The publisher adapter polls the publishing table to check if any new rows have been inserted. Newly inserted rows are fetched using ODBC, packed into a message, and published. 3. The subscriber adapter listens for messages. When a message arrives, the subscriber adapter inserts it into the destination table using ODBC.

Q

Setting Up and Starting the Alerter on Oracle

Tibco Questions


34

The alerter on Oracle uses the Oracle AQ package to send and receive information between sessions, asynchronously allowing two or more sessions in the same database instance to communicate. As shown next, when a source table is updated with data and the commit_and_notify procedure executed, a trigger copies the data to the publishing table and notifies the Oracle AQ that a publishing table has changed. The alerter gets the notification from Oracle AQ and sends a notification message to the adapter that a publishing table has changed. The adapter then queries all its configured publishing tables for the new data and sends it on a subject to the TIBCO transport. One or more instances can be notified.

If there are multiple publishing tables under the same database , you can use the commit_and_notify_table procedure to specify that only a particular table be checked by the adapter. This prevents the adapter from needlessly checking all its publishing tables for updates when only one table has been updated with new data. This notification can be sent to one or more instances To use the alerter, you must install the Oracle AQ package. See your Oracle documentation for information about installing the Oracle AQ package. When configuring the publication service, you must enable the alerter by selecting the Use Alerter option under the Publisher Options tab. When the adapter starts, the alerter will also start. Name Type Description If an adapter that uses the alerter is not shutdown cleanly, you must call the cleanup_alerter stored procedure before restarting the adapter. The procedure is normally called by the adapter when it shuts down cleanly.

Tibco Questions

Synchronous or Asynchronous Message Consumption The API allows for synchronous or asynchronous message consumption. For synchronous consumption, the MessageConsumer explicitly calls the receive() method on the topic or queue. For asynchronous consumption, the client s a MessageListener for the topic or queue. When a message arrives at the destination, the TIBCO Enterprise Message Service server delivers the message by calling the listener’s onMessage() method Flow Control In some situations, message producers may send messages more rapidly than message consumers can receive them. The pending messages for a destination are stored by the server until they can be delivered, and the Tibco Questions


36

server can potentially exhaust its storage capacity if the message consumers do not receive messages quickly enough. To avoid this, TIBCO Enterprise Message Service allows you to control the flow of messages to a destination. Each destination can specify a target maximum size for storing pending messages. When the target is reached, TIBCO Enterprise Message Service blocks message producers when new messages are sent. This effectively slows down message producers until the message consumers can receive the pending messages. Enabling Flow Control The flow_control parameter in tibemsd.conf enables and disables flow control globally for the TIBCO Enterprise Message Service server. When flow_control is disabled (the default setting), the server does not enforce any flow control on destinations. When flow_control is enabled, the server enforces any flow control settings specified for each destination. See Chapter 7, Using the Configuration Files, on page 117 for more information about working with configuration parameters. When you wish to control the flow of messages on a destination, set the flowControl property on that destination. The flowControl property specifies the target maximum size of stored pending messages for the destination. The size specified is in bytes, unless you specify the units for the size. You can specify KB, MB, or GB for the units. For example, flowControl = 60MB specifies the target maximum storage for pending messages for a destination is 60 Megabytes. Enforcing Flow Control The value specified for the flowControl property on a destination is a target maximum for pending message storage. When flow control is enabled, the server may use slightly more or less storage before enforcing flow control, depending upon message size, number of message producers, and other factors. Setting the flowControl property on a destination but specifying no value causes the server to use a default value of 256KB. Configuring Fault-Tolerant Servers To configure an EMS server as a fault-tolerant backup, set these parameters in its main configuration file (or on the server command line): • server Set this parameter to the same server name in the configuration files of both the primary server and the backup server. • ft_active In the configuration file of the primary server, set this parameter to the URL of the backup server. In the configuration file of the backup server, set this parameter to the URL of the primary server. When the backup server starts, it attempts to connect to the primary server. If it establishes a connection to the primary, then the backup server enters standby mode. If it cannot establish a connection to the primary, then the backup server assumes the role of the primary server (in active mode). While the backup server is in standby mode, it does not accept connections from clients. To ister the backup server, the can connect to it using the istration tool. Tibco Questions

Bridge webMethods or TIBCO with another integration What is a TIBCO Domain? Tibco Questions


39

Domain is a collection of hardware and software components that are used for business process integration. The domain defines the TIBCO BusinessWorks environment. Each domain must contain one and only one istration server. Each domain must have a unique domain name. Each domain may contain one or more machines but no single machine can belong to multiple domains. Each machine may have more than one type of software component (BusinessWorks process engine, ActiveEnterprise 4.2 Adapters, etc.) installed. By definition, software components can only be deployed in the same domain that the machine belongs to. What transformation standards does BusinessWorks ? BusinessWorks data transformation is based on XSLT. XPath is used for data manipulation and formula constructions What is XPATH? Xpath is a scripting language developed by the World Wide Web Consortium (W3C) for addressing parts of XML documents. It provides basic manipulation functions for strings, numbers and Booleans. TIBCO Designer, a BusinessWorks component, uses Xpath as the language for defining conditions and transformations. A complete description of Xpath is available http://www.w3c.org How does BusinessWorks SOAP and WSDL integration? BusinessWorks provides WSDL/SOAP integration in a server and a client mode, which integrates directly into the Process Instance. BusinessWorks provides three different components: SOAP Event Source, SOAP Send (Request) Activity, and SOAP Send/Receive (Request/Reply) Activity. In BusinessWorks 2.0, we will only document-centric calling convention and not a procedure-oriented communication. A future version of BusinessWorks will provide for UDDI as well. What is WSDL? WSDL, or Web Services Definition Language, is an XML format for describing network services as a set of endpoints operating on messages containing either document-oriented or procedure-oriented information. The operations and messages are described abstractly, and then bound to a concrete network protocol and message format to define an endpoint. Related concrete endpoints are combined into abstract endpoints or services. What is SOAP? SOAP, or Simple Object Access Protocol, is a lightweight protocol for the exchange of information between web services. BusinessWorks has a SOAP Tibco Questions

What are the different BusinessWorks components? BusinessWorks consists of TIBCO , TIBCO Runtime Agent, BusinessWorks Engine, and TIBCO Designer.

Introduction to EAI Today information technology (IT) has become very critical for successful functioning of any enterprise in this world. Every form of business thrives on some form of automation. Earlier, the automation had been custom developed, but now days everything seems to be through packaged applications, which in a way reduced the amount of software development significantly. Unfortunately these packaged applications, which are selfcontained, have become stove-pipe applications. The requirements for nextgeneration software systems mandate the integration of these stove-pipe applications. The requirements for the next generation software systems mandate the integration of these stove-pipes with new forms of business logic. The term enterprise Application (EAI) has become a recent entrant into the jargon of the active software industry. EAI is a buzzword that represents the task of integration of various applications so that they may share information and processes freely. Thus EAI is the creation of robust and elegant business solutions by combining applications using common middleware and other viable technologies. With these realizations, EAI was created by industry analysts to help information technology organizations to understand the emergence of a type of software that eases the pains of integration. EAI is the nexus of technology, method, philosophy and desire to finally address years of architectural neglect -------SVIT What is TIBCO? TIBCO Software Inc.
