TSQUEUE

The TSQUEUE report set is useful when a CICSĀ® systems programmer sees a notification that one of the CICS regions is experiencing TSQ issues.

When 75% or more of the maximum allowed storage is in use, CICS issues messages about this situation. The systems programmer wants to know what reports to run to determine the causes of the TSQ issues. Based on these reports and analysis, the systems programmer can then consider tuning options as well as further analysis and monitoring.

The TSQUEUE report set produces the following reports:

Report Type Default DDNAME Description
Performance list extended LSTX0001 Temporary Storage Top 20 Worst Tsqueue Requests
Performance list extended LSTX0002 Temporary Storage Top 20 Worst Shared TS Waits
Wait analysis WAIT0001 Wait Analysis Report
Temporary storage usage summary TEMP0001 Transaction Temporary Storage Usage Summary
Statistics summary SSUM0001 Temporary Storage Statistics
Statistics alert STAL0001 Statistics Alerts (List by APPLID and Summary by APPLID)

To produce the reports, TSQUEUE uses the following components:

Component name Component type Description
BADTSRQ form Top 20 Worst Tsqueue Requests. Used by the LSTX0001 report.
BADTSSWT form Top 20 Worst Shared TS Waits. Used by the LSTX0002 report.
TEMPSTG form Temporary Storage Statistics. Used by the SSUM0001 report.
TSQUEUE alert CICS TS Key System Sample Alerts. Used by the STAL0001 report.
