Tibco Part6 Interview Questions and Answers

26.What are the uses of grouping activities ?
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 occurence of multiple events and proceed along a path following the first event to occur.

27.What is the purpose of a Lock shared configuration resource?
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'.

28.How to control the sequence of execution of process instances created by a process starter ?
Use the sequencing key field in the Misc tab of any process starter. Process instances with the same value for this field are executed in the sequence in which they are started.

29.Can there be two error transitions out of an activity ?
No. There can be only one Error and one Success if no matching condition transition out of each activity.

30.When is a 'No Action' group used ?
'No Action' group used to have a set of activities having a common error transition.
