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.

Table 1. Dispatcher domain: Global statistics
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.

Number of Excess TCB Scans DSGXSCNS is the number of CICS dispatcher excess MVS TCB scans.

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.

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.

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.
