MAXTASK
The MAXTASK report set is useful when a CICSĀ® systems programmer sees a notification that one of the CICS regions has reached the MXT limit specified for the region and wants to know what reports to run to determine the causes of the MXT condition. The MXT limit is the maximum number of user tasks that can exist in a CICS system at the same time.
Based on these reports and analysis, the systems programmer can then consider tuning options as well as further analysis and monitoring.
The MAXTASK report set produces the following reports:
Report Type | Default DDNAME | Description |
---|---|---|
Performance list | LIST0001 | MXT exceeded MAXTASKS Analysis by Task Time |
Performance summary | SUMM0001 | MXT exceeded MAXTASKS Analysis by Time-of-Day |
Wait analysis | WAIT0001 | MXT exceeded analysis |
Statistics summary | VIRTSTG | MXT exceeded Virtual Storage Usage Summary |
Statistics summary | TRANMNGR | MXT exceeded Transaction Manager Global Statistics |
Statistics alerts | STAL0001 | MXT exceeded analysis Alerts (List by APPLID, and Summary by APPLID) |
To produce the reports, MAXTASK uses the following components:
Component name | Component type | Description |
---|---|---|
MAXTASK | alert | MXT exceeded analysis alerts. Used by the STAL0001 statistics alert report. |
MXTBYTOD | form | MAXTASKS analysis by time-of-day. Used by the SUMM0001 performance summary report. |
MXTBYTSK | form | MAXTASKS analysis by task time. Used by the LIST0001 performance list report. |
TRANMNGR | form | Transaction manager global. Used by the TRANMNGR statistics summary report. |
VIRTSTG | form | Virtual storage usage summary. Used by the VIRTSTG statistics summary report. |
