CICSplex Dispatcher Summary attribute group

The CICSplex Dispatcher Summary attributes report TCB activity. This includes the number of TCB modes and pools associated with each CICS region, the current and peak number of tasks attached to the CICS region, the current exit interval, the runaway task time, and the terminals scan delay time.

Note:
The attributes within the CICSplex Dispatcher Summary group are stored for historical retrieval within the Tivoli Data Warehouse. Selected attributes within this group are candidates for the TDW's summarization and pruning features.

Average TCBs Detached Is the average number of z/OS TCBs that have been detached by each scan of the CICS dispatcher's excess z/OS TCB management processing.

CICS Region Name Indicates the job name or modify ID of the CICS region being monitored. Each CICS region in a z/OS image has a unique name. This name is an alphanumeric string, with a maximum of 8 characters, and case-sensitive. CICS region names are always in uppercase characters.

Concurrent Subtasks Is the current number of subtasks. It is the current value of the CICS SUBTSKS parameter.

CPU Time since reset Is the accumulated CPU time since statistics were last reset.

Current Attached TCBs Is the current number of CICS TCBs attached in this region. TCBs attached in all CICS TCB Modes contribute to this count.

Current ICV Time Is the current region exit time (ICV) in milliseconds. The region exit interval is the amount of time (in milliseconds), for which CICS releases control to the operating system if no transactions are ready to resume processing. It is the current value of the CICS ICV parameter as specified in the SIT. It can be changed dynamically using CEMT SET SYSTEM TIME(value) or EXEC CICS SET SYSTEM TIME(fullword binary data-value) commands.

Current ICVR Time Is the runaway task time interval (ICVR) in milliseconds. It is the current value of the CICS ICVR parameter as specified in the SIT. It can be changed dynamically using CEMT SET SYSTEM TIME(value) or EXEC CICS SET SYSTEM TIME(fullword binary data-value) commands.

Current ICVTSD Time Is the terminal scan delay time (ICVTSD) in milliseconds. It is the current value of the CICS ICVTSD parameter as specified in the SIT. It can be changed dynamically using CEMT SET SYSTEM TIME(value) or EXEC CICS SET SYSTEM TIME(fullword binary data-value) commands.

Current Number of Tasks Is the current number of tasks attached in this CICS region.

Current PRTYAGING Time Is the priority aging value (PRTYAGE) in milliseconds. It is the current value of the CICS PRTYAGING parameter.

Current Used TCBs Is the current number of CICS TCBs attached in this region which are in use. TCBs attached and in use in all CICS TCB Modes contribute to this count.

Excess TCB Scans Is the number of Excess TCB scans performed by the dispatcher.

MRO (QR) Batching value Is the MRO batching value (MROBTCH). It is the current value of the CICS MROBATCH parameter.

Number of TCB Modes Is the number of TCB Modes defined to this CICS region.

Number of TCB Pools Is the number of TCB pools defined to this CICS region.

Origin Node Is the combination of z/OS System ID (SMFID) and CICS region name. The value format is an alphanumeric string, maximum 32 bytes, and case-sensitive.

When a situation is true, the system compares the origin node name in the attribute to the names of managed systems assigned to the item. If the origin node name matches the name of a managed system, the status of the item changes accordingly. If the names of the origin node and the managed systems do not match, the status of the item remains unchanged.

Peak Number of Tasks Is the peak number of tasks attached in this CICS region.

SRB Time since reset Is the accumulated SRB time since statistics were last reset.

Start Time Is the time at which the dispatcher subtask was initialized.

System ID Indicates the four-character name that uniquely identifies an active z/OS operating system within a given CICSplex. The value format is an alphanumeric string, maximum 4 characters, and case-sensitive. z/OS System IDs are always in uppercase characters.

TCB Scans with a Detach Is the number of excess TCB scans performed by the CICS dispatcher in which a TCB was detached.

TCB Scans with no Detach Is the number of excess TCB scans performed by the CICS dispatcher in which no TCBs were detached.
