Subject: CICS transaction slow response time
Posted: Thu Jan 19, 2017 1:31 am (GMT 5.5)
Hi,
We have a CICS-DB2 transaction that ran for 40 seconds and we are trying to determine where that 40 seconds was spent.
The transaction started on say 11:00:00 sharp it ended at 11:00:40, The CICS transaction made a DB2 call at 11:00:01 and the DB2 thread completed at 11:00:02. So we are trying to determine what was happening from 11:00:02 till 11:00:40. We have DB2 datasharing in place.
Mainview monitor for CICS and CICS SMF records show that approximately 39 seconds was spent on
RMIDBCTM - RMIDBCTL*DURATION*IN DFHRMI - 39 seconds
WTSYIOTM - SYNCPOINT*IO WAIT TIME - 39 seconds.
I am not sure what is causing these high values in SYNCPOINT. Could you please let me know where to look for the problem from here.
I was thinking to look at Coupling facility next.
Thanks & Regards,
