15. How Restful web services can be developed in TIBCO?


TIBCO provides a Plugin for REST and JSON which can be used to develop Restful web services in TIBCO designer.

16. Can we have backward transitions in TIBCO BW Processes?


In TIBCO Designer Processes, transitions between activities are always uni-directional. This means that we can’t go back to a previous transition from any point.

17. What are different Panels of TIBCO designer window and what is the purpose of each?


There are following four types of panels available in TIBCO designer window:

  • Project Panel: This panel shows project hierarchy.
  • Design Panel: This panel is used to design new BW Processes in TIBCO.
  • Palette Panel: This Panel has all the available Palettes with bundled activities which can be dragged and used in design panel during process development.
  • Configuration Panel: Configurations including input, output details for any activity are specified in the configuration panel.

18.What is difference between fault tolerant and Load balanced deployment in TIBCO?


Load balancing:

Load balancing is done between two or more servers where the load is distributed between servers to avoid any server crashes due to heavy load on a single server.

Fault tolerance:

Fault tolerance is achieved between two servers where one server acts as a primary and the second server acts as a secondary/backup server for the primary server. Whenever failure occurs for primary server, the backup secondary server becomes the primary server.

19. What are the options for configuring storage for process engine’s checkpoint repository ?


The options for configuring storage for process engine’s checkpoint repository are:

Local File: Information is stored in a local file which in case of engine crash/failure and same information is used to resume the process flow once engine is up. This mechanism works only in case of single server or load balancing approach.

Database: Information is stored in a database table which is used to resume engine later. Fault tolerant engines can recover from a checkpoint only when database is used.

20. How do you send a response from a web service?


We write to output to the queue from which we received the request.

21. Have you heard about personalized information link?


Yes, using this method we can filter the users to view the dashboard. Two parameters are used for this.


From version 6 onwards there is one more named CURRENT_USER_DOMAIN. 

22. Have you ever created dashboard using procedures with input parameter? If your answer is yes, definitely the next question will be how?


You can create the procedures through IL, instead of table columns create procedures. While creating the procedures there is one option to select the query type. If it is with input parameters change that to post – query, write default values and save. Create IL using the procedure, and refresh the parameters to get the values.

23. Can we use different filters on different pages?


We can use filtering schema to apply different filter.

24. The way dashboard using IL (information link)?


First, create the data source, then take the columns you wanted for the dashboard and save in a folder in the library. If using multiple tables, create the joins. Finally, create the IL. Add data from the library to access the IL to the front end. 

25. What are the three levels of validations that can be performed in TIBCO designer?


  • Following are the three levels of
  • validations supported by TIBCO BW:
  • Activity level validation
  • Process level validation
  • Project level validation

26. Are you able to edit the marking, the name, and color?


Yes, from the Document Property, we can change the marking properties based on your requirement.

27. Is there any difference between the terms Data on Demand & Details on Demand?


Data on Demand is one of the methods we used to add data and Details on Demand is the way of displaying the detailed view of data.

28. Tell me the way you created the dashboard using IL (information link).


First create the data source, then take the columns you wanted for the dashboard and save in a folder in the library. If using multiple tables, create the joins. Finally, create the IL. Add data from the library to access the IL to the front end. 

29. What are the transactions in Tibco?


In Tibco, every transaction is a business-related message. We have JNDI, XA transactions available in Tibco.

30. What is the difference between in-memory ledger and file ledger in TIBCO?


Programs that require certification only for the duration of the program process can choose a process-based ledger. Once the process terminates the ledger file is no longer available. Programs that require certification that transcends process termination and program restart can choose a file-based ledger. Therefore, a file-based ledger preserves certified delivery information beyond transport invalidation, or process termination and restart. A memory/process-based ledger does not possess these characteristics.

31. What are the different modes of service invocation?


Services can be invoked in several ways.

A one-way operation is executed once and does not wait for a response.

A request-response operation is executed once and waits for one response. In a request-response service, communication flows in both directions. The complete interaction consists of two point-to-point messages—a request and a response. The interaction is only considered complete after the response has arrived.

Publication (notification) means an operation sends information on an as-needed basis, potentially multiple times.

Subscription means incoming information is processed on an as-needed basis, potentially multiple times.

32. Can we use Multicast on queues?


No, multicast can be used only for topics. Queues are a point to point and can’t be used for multicast.

33. Where we will go for ADB adapter and JDBC Activities?


We can go for ADB adapter where the data flow is synchronous and data integration is required between multiple databases. Whereas JDBC Activities can be used for asynchronous operations and where data integration is not required.

34. What are the resources that get included in the EAR file, created by the TIBCO Designer?


An EAR file can contain local project resources, Library Builder resources, and files as specified in Alias Library resources. In addition, the TIBCO Designer classpath may include references to other files that are included in the EAR file.

35. What are the different types of Transactions TIBCO provides?


TIBCO BusinessWorks offers a variety of types of transactions that can be used in different situations. You can use the type of transaction that suits the needs of your integration project. When you create a transaction group, you must specify the type of transaction.

TIBCO BusinessWorks supports the following types of transactions:

  1. 1. JDBC
  2. 2. Java Transaction API (JTA) UserTransaction
  3. 3. XA Transaction

36. Is it possible to create a drop-down filter?


Yes, using the text area you can create a drop-down filter.

37. What is prefetch and failsafe?


Prefetch is fetching the messages from the server before receiver calls. Failsafe property enables to write persistence messages to the file with synchronous i/o calls.

38. What is the difference between SQL direct and other JDBC activities?


Other JDBC activities can only do a specific DML operation (insert, update, modify), whereas sql direct can execute all the DML operations including table creation and deletion too.SQL direct is mainly used for dynamic DB operations. 

39. What is the difference between parsed XML and render XML?


Parse XML will parse the XML content as per the XML Schema or DTD or XSD that we defined. Render XML will render the data from the output and provide an XML string as per the Shema or XSD we defined.

40. Does Copy Create File Activity Allows Creating New Directories?


Yes. The Create File activity creates a new file or directory with the specified name. When creating a file, you can also provide the file contents.

41. What Is The Difference Between Concrete Wsdl And Abstract Wsdl?


The Abstract WSDL describes the interface of the web service which includes the format of request and response messages of each operation.

The Concrete WSDL describes the abstract WSDL plus transport information. Concrete WSDL contains messages, operations and transport specific information (JMS or Http), which is used by SOAP client.

42. What is the use of spawn option in the called process?


If the spawn is checked, then that process will be executed externally with the main process. And we are not supported to make this spawn when we are using job shared variables.

43. What Is The Use Of Critical Section Group?


Critical section groups are used to synchronize process instances so that only one process instance executes the grouped activities at any given time.

44. What are TIBCO Ledger files and why they are important?


TIBCO Ledger files are used to store messages in case of RV certified messaging. Ledger files are important as they ensure delivery of each and every message to the intended recipient in a certified RV communication model in TIBCO. 

45. How Do You Use Xslt File?


The Transform XML activity allows you to transform an input XML document into the output specified by the given XSLT File shared configuration resource.
