Dispatcher report
The Dispatcher report is produced using a combination of the EXEC CICS INQUIRE SYSTEM and EXEC CICS EXTRACT STATISTICS DISPATCHER commands. The statistics data is mapped by the DFHDSGDS DSECT.
| Field Heading | Description |
|---|---|
| Current ICV time | The current interval control value,
expressed in milliseconds. Source field: DSGICVT |
| Current ICVR time | The current task runaway time interval,
expressed in milliseconds. Source field: DSGICVRT |
| Current ICVTSD time | The current terminal scan delay value,
expressed in milliseconds. With SNA and IPIC networks, the default
ICVTSD value of 0 is appropriate. Source field: DSGICVSD |
| Current PRTYAGING time | The current task priority aging factor.
Source field: DSGPRIAG |
| MRO (QR) Batching (MROBTCH) value | The number of events that must ocur
before CICS® is posted for dispatch due to the batching
mechanism, as specified in the MROBTCH value in the SIT. Source field: DSGMBTCH |
| Concurrent Subtasking (SUBTSKS) value | The number of task control blocks
(TCBs) that CICS can use for running tasks in concurrent
mode, as specified in the SUBTSKS SIT parameter. Source field: DSGSTSKS |
| Current number of CICS Dispatcher tasks | The current number of tasks in the
system. This figure includes all system tasks and all user tasks.
Source field: DSGCNT |
| Peak number of CICS Dispatcher tasks | The peak number of tasks concurrently
in the system. Source field: DSGPNT |
| Current number of TCBs attached | The current number of TCBs attached
for this CICS address space. Source field: DSGTCBCA |
| Current number of TCBs in use | The number of CICS TCBs in use. Source field: DSGTCBCU |
| Last Excess TCB Scan | The date and time of the last CICS dispatcher
excess MVS TCB scan. If the DFH0STAT report shows the date and time as --/--/---- --:--:--:---- then that indicates that an excess TCB scan has not happened yet. Source field: DSGLXSCN Reset characteristic: not reset |
| Number of Excess TCB Scans | The number of excess TCB scans performed
by the CICS dispatcher. Source field: DSGXSCNS |
| Last Excess TCB scan — No TCB Detached | The date and time of the last CICS dispatcher excess MVS TCB scan that did not detach any TCBs. If the DFH0STAT report shows the date and time as --/--/---- --:--:--:---- then that indicates that an excess TCB scan has not happened yet. Source field: DSGLXSND Reset characteristic: not reset |
| Excess TCB scans — No TCB Detached | The number of excess TCB scans performed
by the CICS dispatcher during which no CICS TCBs
were detached. Source field: DSGXSCNN |
| Number of Excess TCBs Detached | The number of CICS TCBs
that were detached by the CICS dispatcher during excess TCB
scans. Source field: DSGXTCBD |
| Average Excess TCBs Detached per Scan | The average number of CICS TCBs
that were detached by the CICS dispatcher during each excess
TCB scan. Source field: DSGXTCBD / DSGXSCNS |
| Number of CICS TCB MODEs | The number of CICS TCB
modes for this CICS address space. Source field: DSGASIZE |
| Number of CICS TCB POOLs | The number of CICS TCB
pools for this CICS address space. Source field: DSGPSIZE |
