A Lock is specified for a ‘Critical Section’ group when the scope is ‘Multiple’. It can be used to ensure synchronization across process instances belonging to multiple processs definitions or for process instances across engines(Check multi engine flag for lock in this case and the BW engine needs to be configured with database persistence while deployment). If synchronization is for process instances belonging to the same processs definition inside one engine, just specify the scope as ‘Single’.

24. Process engines in a fault tolerant group can be configured as peers or master secondary.How do these differ?_text]Answer:

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

  • Peer means all of them have the same weight. In this case when one engine fails another one takes over and continues processing till it fails.(Tibco BW Online Training)
  • In master secondary configuration weights are unequal, the secondary starts processing when master fails. But when master recovers, secondary stops and master continues processing.

25. What is meant by service and daemon in Rendezvous?_text]Answer:

TIBCO RV Service is the UDP Port number on which Rendezvous messages are sent. Daemon is the port number on which communication takes place between RVD and application.

27. What is the difference between shared variable, job shared variable, process variables and global variables?_text]


Shared variables can be accessible by multiple process definitions, and can Changeable by any process definition.Job Shared variables can be accessible within the execution jobs, and it will maintain a copy of variable for every job (execution).Process Variables can only be access for a particular process where it gets defined.Global variable can be accessible by across the project. Global variable can be edi that runtime too in Tibco administrator.(Tibco Video Training)

28. What is the difference between reliable, certified, distributed queues in RV?_text]


Reliable: Delivery guarantee in the reliable mode, subscriber can send the re-transmission request for the lost packets.

Certified: Certified messaging assures that both pub/subs are in certified mode of message delivery. And packets/messages will be stored on a ledger file. So that lost messages or packets can be delivered as per the re-transmission request.

Distributed: Distribute Queue is to share load between the workers; this will handled by Load balancing concept. Whoever is having highest work will be acting as scheduler and also we can decide worker capacity as well DQ-Load balancing!

29. What are the uses of grouping activities?_text]Answer:

Uses of grouping activities are:

  • Create a set of activities having a common error transition.
  • Repeat group of activities based on a condition.

1. Iterate over a list.
2. Repeat until condition true.
3. Repeat on Error until condition true.

  • Group activities into a transaction.
  • To create a critical section area that synchronizes process instances.
  •  A ‘Pick First Group’ allows you to wait for the occurrence of multiple events and proceed along a path following the first event to occur.

30. What is the purpose of Retrieve Resource activity?_text]


The Retrieve Resources activity generates a WSDL file containing a concrete service(Conrete WSDL) description of any process definition that has a SOAP Event Source process starter. This allows clients to access the WSDL for a web service. The client can then use the WSDL file to invoke the web service. The Retrieve Resources activity can also be used to retrieve any other resources, including XSDs and WSIL.
