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 |
