Situation Description

Critical threshold exceeded for low CICS working set

 

Suggested Actions

Use the Transaction Analysis report to check whether there are any active transactions. If there is task activity, monitor the page-in rate with the Region Overview report. A low working set may be caused by frequent variations in the number of page-ins that CICS is doing. Consider storage isolation (set in the MVS IPS) to control the average CICS working set size.
