Monitor thread causing DB2 abend

Hi Team,

We had a Db2 system abend for production environment because of  QUERY ON BLOCKING_THREADS has cancelled . We had a business impact for this. If we can monitor such thread proactively before it get cancel, then it may save us from DB2 abend through which we can avoid business impact.

 

Thanks,

Prakash

    Dear Prakash,

    Thank you for submitting this enhancement request. Our Db2 for z/OS team reviewed it and determined Db2 for z/OS Hiper APAR PH52180 fixed the reported abend04E reason 00E3007B in DSNTGSCC.DSNTABA +00D9E due to a cancel window. In general, cancel a query that references the Blocking_Threads UDF should not cause Db2 abend. The Db2 for z/OS team believes they have handled the specific cancel window in the middle of an IRLM notify message while invoking the UDF.

    Therefore, we have closed this Aha! idea as 'Functionality already exists'.

    We appreciate your input to the Db2 for z/OS development team. And we hope that you will continue to submit enhancement suggestions for improvements as customer feedback is a key component to shaping the future direction of Db2 for z/OS.

    Sincerely,

    Db2 for z/OS team
