Question
It is possible to cancel DB2 Thread causing contention with Task or Job
A. Not possible
B. Possible
C. Can’t say
D. None
Answer
The correct answer is B. It is possible to cancel a DB2 thread that is causing contention with a task or job.
Explanation
When a DB2 thread is causing issues by holding locks or resources needed by other tasks or batch jobs, canceling that thread can resolve the contention. The DB2 command used to cancel a thread is:
-CANCEL THREAD(token)
This will force the thread to terminate, releasing any locks or resources it was holding. The thread’s current unit of work will be rolled back.
However, caution should be used when canceling threads, as it can cause data integrity issues if not done carefully. The application associated with the cancelled thread may need to be restarted. And frequent thread cancellations can be a sign of poorly designed applications or DB2 configuration issues that should be investigated and resolved.
So in summary, while it is possible and sometimes necessary to cancel a DB2 thread to resolve contention, it’s an action that should be taken judiciously. Proper monitoring and well-designed applications are preferable to relying on cancelling threads. But the capability is available when needed to unblock tasks or jobs.
