CICSplex Dispatcher TCB Modes attribute group

The CICSplex Dispatcher TCB Mode attributes report CICS dispatcher TCB mode information in an active system that is being managed by CICSPlex SM.

Note:
The attributes within the CICSplex Dispatcher TCB Modes 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.

Accumulated time spent in z/OS Waits Is the accumulated real time that the CICS region was in a z/OS wait, that is, the total time used between a z/OS wait issued by the dispatcher and the return from the z/OS wait. It is measured in milliseconds.

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

CPU Time for dispatcher task Is the accumulated CPU time taken for this DS task, that is, the processor time used by this TCB while executing the default dispatcher task (DSTCB). It is measured in milliseconds.

Current TCBs Attached Is the current number of z/OS TCBs attached in this CICS dispatcher TCB mode.

Current TCBs in Use Is the current number of z/OS TCBs in use in this CICS dispatcher TCB mode.

Number of excess detaches Is the number of z/OS TCBs that have been, or are in the process of being, detached from this CICS dispatcher TCB mode because of the dispatcher excess TCB management processing.

Number of other detaches Is the number of z/OS TCBs that have been, or are in the process of being, detached from this CICS dispatcher TCB mode. This might be because, for example, the limit for the number of TCBs allowed in the TCB pool has been lowered, or there are too many TCBs attached in relation to the number of TCBs in use.

Number of stolen detaches Is the number of z/OS TCBs that have been, or are in the process of being, stolen from this CICS dispatcher TCB mode because it is required by another TCB mode.

Number of unclean detaches Is the number of z/OS TCBs that have been, or are in the process of being, detached from this CICS dispatcher TCB mode because the CICS transaction that was associated with the TCB has terminated.

Number of partition exits Is the number of partition exits that have occurred for this TCB mode.

Number of TCB mismatches Is the number of z/OS TCB mismatches that have occurred for this TCB mode.

Number of TCB steals Is the number of z/OS TCBs that have been stolen from other TCB modes.

Open Indicates whether the CICS dispatcher TCB mode is Open, Not open or Unknown. A CICS dispatcher TCB mode of type 'unknown' Indicates that this TCB mode has not been activated.

Origin Node 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 TCB Attached Is the peak number of z/OS TCBs attached in this CICS dispatcher TCB mode.

Peak TCBs in use Is the peak number of z/OS TCBs in use in this CICS dispatcher TCB mode.

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 Attach Failures Is the number of z/OS TCB attach failures that have occurred in this CICS dispatcher TCB mode.

TCB Attaches Is the number of z/OS TCBs that have been attached in this CICS dispatcher TCB mode.

TCB Mode Name Is the two-character name of the CICS Dispatcher TCB mode, either QR, RO, CO, SZ, RP, FO, SL, SO, S8, D2, JM, L8, J8 or J9.

TCB Mode Pool Is the name of the CICS TCB pool, either OPEN, Hot-Pooling, XPLink, JVM, SSL, or n/a.

TCBs Allocated Is the number of times that a TCB was allocated to a task.

Total CPU time used by this TCB Is the accumulated CPU time taken for this TCB, that is, the total time that this TCB has been in execution. It is measured in milliseconds.

Total time TCB has been dispatched by z/OS Is the accumulated real time that this TCB has been dispatched by z/OS, that is, the total time used between a z/OS wait issued by the dispatcher and the subsequent wait issued by the dispatcher. It is measured in milliseconds.
