Detecting CICS transactions waiting on Db2 threads

IBM Service Management Unite can detect and respond to CICS transactions that are waiting on Db2 threads.

The consolidated event viewer displays monitoring and automation exception events, filtered by severity and customized for your area of support. In this scenario, the top unacknowledged event is a warning for a group resource that is owned by CICS Region CICSTIV1. The user right-clicks on the event and selects View CICS Region Details for CICSTIV1.

The CICS Region Details page displays key performance metrics to help determine that CICS transactions are waiting on Db2 threads. From the Bottleneck Summary view, the user can see that DBIC tasks appear to be waiting on the CDb2RDYQ ready queue a significant amount of the time.

To restore service, the user contacts the CICS systems programmer to change the CICS configuration to lower the wait time.
