Dispatcher domain: Global statistics
You can retrieve dispatcher domain global statistics by using the EXEC CICS EXTRACT STATISTICS DISPATCHER system command. They are mapped by the DFHDSGDS DSECT.
DFHSTUP name | Field name | Description |
---|---|---|
Dispatcher Start Date and Time | DSGLSTRT | is 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 | is 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 | is 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 | is 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 | is 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 | is the peak value of the number of dispatcher
tasks concurrently in the system. Reset characteristic: reset to current value
|
Current ICV time (msec) | DSGICVT | is 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 | is 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 | is 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 | is 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 | is 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 | is 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 | is 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 | is 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 | is 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 | is 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 | is 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
