Dispatcher domain: Global statistics
You can retrieve dispatcher domain global statistics by using the EXEC CICS EXTRACT STATISTICS DISPATCHER command. They are mapped by the DFHDSGDS DSECT.
| DFHSTUP name | Field name | Description |
|---|---|---|
| Dispatcher Start Date and Time | DSGLSTRT | The date and time at which the CICS® dispatcher started. This value can be used as an approximate
time at which CICS
started. The DFHSTUP report expresses this time as day/month/year
hours:minutes:seconds.decimals; however, the DSECT field contains the time as a store
clock (STCK) value in local time. Reset characteristic: not reset |
| NOT IN DFHSTUP REPORT | DSGSTART | The time at which the dispatcher started. This value can be used as an
approximate time at which CICS started. The DFHSTUP report expresses this time as
hours:minutes:seconds.decimals; however, the DSECT field contains the time as a
store clock (STCK) value in GMT. Reset characteristic: not reset |
| Address Space CPU Time | DSGEJST | The total CPU time for all TCBs in this address space, accumulated during the
interval. The DFHSTUP report expresses this as
days-hours:minutes:seconds.decimals.
Reset characteristic: reset to zero |
| Address Space SRB Time | DSGSRBT | The total CPU time for all service request blocks (SRB) executed in this address
space, accumulated during the interval. The DFHSTUP report expresses this as
days-hours:minutes:seconds.decimals.
Reset characteristic: reset to zero |
| Current number of dispatcher tasks | DSGCNT | The current number of dispatcher tasks in the system. This figure includes all
system tasks and all user tasks. Reset characteristic: not reset |
| Peak number of dispatcher tasks | DSGPNT | The peak value of the number of dispatcher tasks concurrently in the system.
Reset characteristic: reset to current value |
| Current ICV time (msec) | DSGICVT | The ICV time value (expressed in milliseconds) specified in
the SIT, or as an override, or changed dynamically using the EXEC CICS SET SYSTEM
TIME(fullword binary data-value) command. Reset characteristic: not reset |
| Current ICVR time (msec) | DSGICVRT | The ICVR time value (expressed im milliseconds) specified in the SIT, or as an
override, or changed dynamically using the EXEC CICS SET SYSTEM TIME(fullword binary
data-value) command. Reset characteristic: not reset |
| Current ICVTSD time (msec) | DSGICVSD | The ICVTSD time value (expressed in milliseconds) specified
in the SIT, or as an override, or changed dynamically using the EXEC CICS SET SYSTEM
SCANDELAY(fullword binary data-value) command. Reset characteristic: not reset |
| Current PRTYAGE time (msec) | DSGPRIAG | The PRTYAGE time value (expressed in milliseconds) specified in the SIT, or as
an override, or changed dynamically using the EXEC CICS SET SYSTEM AGING(fullword binary
data-value) command. Reset characteristic: not reset |
| Current MRO (QR) Batching (MROBTCH) value | DSGMBTCH | The MROBTCH value specified in the SIT, or as an override, or changed
dynamically using the EXEC CICS SET SYSTEM MROBATCH(fullword binary data-value)
command. Reset characteristic: not reset |
| Last Excess TCB Scan | DSGLXSCN | The date and time of the last CICS dispatcher excess MVS TCB scan. If the DFHSTUP report shows the date and time as --/--/---- --:--:--:---- then that indicates then an excess TCB scan has not happened yet. Reset characteristic: not reset |
| Number of Excess TCB Scans | DSGXSCNS | The number of CICS dispatcher excess MVS TCB scans. Reset characteristic: reset to zero |
| Last Excess TCB Scan–No TCB Detached | DSGLXSND | The date and time of the last CICS dispatcher excess MVS TCB scan that did not detach any
TCBs. If the DFHSTUP report shows the date and time as --/--/---- --:--:--:---- then that indicates then an excess TCB scan has not happened yet. Reset characteristic: not reset |
| Number of Excess TCB Scans–No TCB Detached | DSGXSCNN | The number of excess MVS TCB scans that resulted in no MVS TCBs being detached by the CICS dispatcher. Reset characteristic: reset to zero |
| Number of Excess TCBs Detached | DSGXTCBD | The total number of MVS TCBs that have been detached by the CICS dispatcher's excess MVS TCB management processing. Reset characteristic: reset to zero |
| Average Excess TCBs Detached per Scan | Not Applicable | The average number of MVS TCBs that have been detached by each scan of the CICS dispatcher's excess MVS TCB management
processing. Reset characteristic: reset to zero |
| Number of CICS TCB MODEs | DSGASIZE | The current number of CICS TCB modes in which the CICS dispatcher is managing MVS task control blocks (TCBs) in the
system. Reset characteristic: not reset |
| Number of CICS TCB POOLs | DSGPSIZE | The number of TCB pools in which the CICS dispatcher is managing MVS task control blocks
(TCBs) in the system under which the CICS dispatcher runs. Reset characteristic: not reset |
