TCB/SRB Use Summary Information

If the MUF startup option SMPTASK was specified and TCB mode was specified, this report on CPU time used by each Task Control Block (TCB) can be useful.

If the MUF startup option SMPTASK was specified and SRB mode was specified, an ENCLAVE SRB USE SUMMARY INFORMATION section occurs (see Enclave SRB Use Summary Information).

In TCB mode, the SMP subtask has a program name of DBSMPPR in the report, as it did in prior releases.

In SRB mode, the SMP task has a program name of *SRB-SMP in the report.

DBSMAPR subtasks are listed in the report with a program name of DBSMAPR.

This page of the report provides the following information:

ITEM

The first item represents the MUF main task. The second and any following items represent either TCBs for subtasks or SRBs used as SMP tasks.

PROGRAM

Displays the name of the program.

DBCONPR

Console driven subtask

DBCPMPR

The Change Data Capture Monitor subtask in the source MUF (see Change Data Capture in the CA Datacom/DB Database and System Administration Guide.)

DBDUSPR

DBDUSPR exists, if needed, for PXX and (or) SYSOUT processing.

DBENQPR

Enqueue locking subtask

DBIOSPR

asynchronous I/O functions subtask (See MUF startup option IOTASK in CA Datacom/DB Database and System Administration Guide.)

DBMUFPR

Main task

DBMSBPR

Timer control subtask

DBOCSPR

Open/close subtask (In z/OS there are two, in z/VSE there is one.)

DBOC2PR

Second open/close process subtask (z/OS only)

DBSMAPR

DBSMAPR exists for each SMPTASK, if the SRB option was specified.

DBSMPPR

SMP subtask (See MUF startup option SUBTASK in CA Datacom/DB Database and System Administration Guide.)

DBSPSPR

Active recovery spilling subtask

USED COUNT

Lists the number of times an internal unit of work was performed. The count of internal units of work cannot be compared to any other CA Datacom/DB counter.

CPU TIME

Displays the total CPU time for the TCB or SRB used in hours, minutes, seconds, and hundredths of a second.

TIMES POSTED

Displays the number of times individual TCBs or SRBs went into a wait (no work to do) and were posted to start processing. Once any of the TCBs are posted, they run (and take new work) until no work exists to be done. The information provided in this field could be useful in tuning the ready-to-run option on the SMPTASK MUF startup option.

I/O COUNT

Displays the I/O count.
