5. What are the Tibco BW activities that can participate in transactions?

Ans: Not all the Tibco BW activities that can participate in the transaction;

• JDBC activities
• JMS activities
• Active enterprise Adapter activities that use JMS transports
• EJB activities
• Tibco I process business works connector activities.

6. Can you please define the error handling mechanisms?

Ans: Errors can be handled by generating the error, rethrow, and catch mechanisms.

7. Explain the process of configuration parameters –max jobs, flow limits, and activation limits?

Ans: Max Jobs: The Max Job specifies the number of processes that are available as an instance in the memory. Once the limit reaches the newly created instances they will be pages out to disk.

Flow Limit: The flow limit specifies the maximum number of running instances that are available before the process starter is suspended. This limit can be used to control the number of instances that are running simultaneously and enables protocols to generate different events.

Activation limits: Activation limit specifies the flag that is loaded instantly in the memory. By default, it is enabled.

10. What type of resources in the Tibco BW EAR file?

Ans: Following are the very important types of resources in the Tibco BW EAR file;

• Local Project Resources which contains processes, connections, schemas, services, and variables.
• Library builder resource files.
• Files referred in designer CLASSPATH
• Files under the designer installation directory.

11. What is vcrepo. Dat and when this file is created in Tibco?

Ans: Vcrepo.dat file in Tibco is used to store various properties of business tools such as RV encoding feature, display name, and description, etc. Vcrepo.dat file gets created automatically when Tibco BW project is saved for the very first time. This type of file can be used for identification purposes.

12. While debugging Tibco BW processes, which activity can be used to write complete schema information to a file?

Ans: Tibco BW offers various inspector activities this can be used to write debugging purposes. This Inspector activity can be used to write all the output information of Tibco designer and will be stored in a local file including local variables and process variables detail.

13. How result web services can be developed in Tibco BW?

Ans: Tibco BW software tool provides Plugins for REST and JSON. These can be used to develop Restful web services in Tibco BW designer.

14. Can we have backward transitions in Tibco BW processes?

Ans: In the Tibco BW designer process, the transitions between activities are considered uni-directional.  This Uni-directional way means we can’t go back to the previous transition from any point during the time of the software process.

15. What are the different panels of Tibco BW designer window and what is the purpose of each?

Ans: The following are the four types of panels available in the Tibco BW designer window;

• Project panel: This panel is used to show the project hierarchy.
• Design panel: This panel is used to design a new Business warehouse process in the Tibco tool.
• Palette Panel: This panel contains all the available palettes with bundled activities this can be dragged and used to design any panel type during the process of panel development.
• Configuration panel: Configuration in Tibco includes input, output details for any processing activity which are defined in the configuration panel.

16. What are the three levels of validations that can be performed in Tibco designer?

Ans: The below are the important validation levels that can be performed in Tibco designer;

·  Activity level validations

·  Process level validations

·  Project level validations

17. What are the differences between fault-tolerant and load-balanced deployment in Tibco?

Ans: 

•  Load balancing: Load balancing can be done between two or more database servers where the load is distributed between servers to avoid any type of crashes due to heavy load on a single server.
•  Fault tolerance: Fault tolerance can be done between two servers where one server acts as a primary source and the second server acts as a backup server or secondary server. Whenever a failure occurs in the primary server, the backup or secondary server acts as a primary server.

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

Ans: There are various options available to configure the storage process engines in the checkpoint repository;

Local file: in this local file type the information can be stored. This type of information is used when engine cash or failure occurs and later the same information is used to resume the process flow once the engine gets started. This type of mechanism works only when a single server or load balancing approach.

Database: here all the information can be stored in a database table which is later used to resume the engine later. This type of database configuration engine is used when engines need to be recovering from a checkpoint only when the database is used.

23. What is concrete WSDL and Abstract WSDL?

Ans: Concrete WSDL contains transport details and this also abstracts the WSDL.

Abstract WSDL contains port messages and information about the port type.

24. What are the uses of Checkpoint and confirm activity?

Ans: Confirm activities are used to provide the client acknowledgments.

Checkpoints are mainly used during the time of BW engine failure occurs, and also helps to avoid duplications while saving the data.
