8. What do you mean by RMS and mention its uses?

Ans: RMS is also known as Rule management Server this is a business event component. This is used to manage decision projects and also provides various mechanisms.

• This RMS offers user authentication, authorizing project decisions, and also consists of project management features.
• This RMS enables the decision manager to communicate the rule management server and also helps users to check project decisions, decision tables of local copies, and commit changes.

9. How can we prioritize and de-prioritize rules for a business event?

Ans: In the Tibco business event tool, to perform a specific event, users can have multiple event rules. The rule priority value can be decided on the base of the sequence where rules are triggered. The value which is closer to 1 means that we can have a higher priority.

10. Describe the flow messages used in the Tibco Business event?

11. What is CDD and what’s its significance?

Ans: CDD stands for Cluster deployment description, this is an XML file. This file consists of required information related to the deployment of the Tibco business event project.

12. Why scorecards are used in the Business event?

Ans: Scorecards are a type of concept used in business events. Scorecards are sometimes used as a static variable in various programming languages, this scoreboard offers project-wide scope and single instance. These scoreboards are used to keep track or store the information which is later used throughout the project interference agent.

13. Mention the steps involved in the Tibco business event installation process?

Ans: The steps included are;

1. Installation guide -> this gives complete installation information

2. Application Architect’s guide -> this consists of details like architectural details or rule programming.

3. Application Developer’s guide -> this consists of details like programmer documents used in rule programming.

4. Decision manager user’s guide -> this gives details like user documentation and decision tables information.

5. Web studio user’s guide -> consists of user documentation available on Web studio.

6. Architect’s guide -> Consists of architectural details on the application platform.

9. System guide -> which consists of machine resources information for the application.

10. Code snippets -> source code for the programming snippets and java developer’s guide.

13. Mention the difference between Tibco BW and Tibco BE?

Ans: Tibco BW is also known as the information bus company warehouse tool. This is an information, integration, and analytical tool. Tibco BW software is used to manage, integrate, and monitor the business level enterprise tool. This is widely used because of its flexibility, scalability, and reliability.

Tibco BE is a tool used to process complex business events. These business events are used to predict any business changes and enable them to perform in a better way.

14. What is an event preprocessor and explain?

15. What is the relationship between decision tables and virtual rule functions?

Ans: Decision tables are considered as an implementation for virtual rule functions. And virtual rule functions consist of one or more decision tables.

17. What is the use of TIBCO BE Concepts?

Ans: The concepts are built to hold any entity’s properties. In the Rules and Rules Functions, Concepts’ instances are often produced using data from the events.

18. What is the use of Routers?Ans. Routers help move messages between the different EMS servers.

Ans: Routers help move messages between the different EMS servers.

19. List out the various acknowledgement modes in TIBCO EMS.

Ans: These acknowledgement modes available in TIBCO EMS for message delivery included.:-

• Auto
• Client
• Explicit
• Dups_ok
• Transitional
• No_ack

20. What is the way to Configure a Client for Fault Tolerant Connection?

Ans: Here, it needs to mention different servers as a comma-separated list of various URLs, and both URLs should use the same protocols. Such as TCP or SSL. 

21. Name the various messages used in EMS.

Ans: The following types of messages are used in EMS.

• Text
• Stream
• Bytes
• Simple
• Map
• Object 
• XML Test

22. How can we develop RESTful Web Services in TIBCO?

Ans: TIBCO offers a plugin for JSON and REST, which help develop RESTful Web Services within TIBCO Designer.

23. Define the process of integrating TIBCO BE with TIBCO BW.

Ans: Based on the configured channel type in TIBCO BE, you can easily send messages to TIBCO BW and get responses. For example, if TIBCO BE configures a JMS channel, you can send JMS messages to specific destinations from TIBCO BW. Then you will get a response through the Recieve JMS Message activity.

24. What does a Flow Control Property state in TIBCO?

Ans: It states the maximum size of messages pending on the server.

25. Name the storage methods used in TIBCO EMS Server.

Ans: There are two storage methods- Database and File Based.

26. Mention the various Delivery modes supported by TIBCO EMS.

Ans: The following are the various delivery modes that TIBCO EMS supports:-

• Persistent
• Non-persistent
• Reliable

27. Define Shared State in the fault-tolerant operations in TIBCO.

Ans: In TIBCO, the fault-tolerant servers connect with Shared State, which includes persistent messages and client information.

28. Distinguish between Rendezvous (RV) and EMS.

Ans: Both are different products and have different architectures. TIBCO EMS uses a client-server architecture, and RV uses distributed architecture. Further, EMS uses the TCP protocol, whereas RV uses the TRDP protocol offered by TIBCO. In EMS, the producer sends messages to the central server, whereas in RV, the producer directly sends messages to the consumer.

29. What is meant by Fail Safe in TIBCO BE?

Ans: The Fail Safe attribute controls whether the server writes persistent messages asynchronously or synchronously to the disk. Also, the messages sent are securely stored on the disk before they are sent. It ensures that no messages are lost.
