(z/OS only) If SRB mode was specified with the SMPTASK Multi-User startup option, the MUF_SRB_ZIIP (MZI) Dynamic System Table has one row for each SMP subtask that was designated on the SMPTASK Multi-User startup option parameter used to specify the maximum number of SMP subtasks,
Information provided by the MZI table is updated periodically by the specific subtask, based on usage counts, which means that it is therefore not necessarily current. It does, however, provide performance information with minimal impact.
The MUF_SRB_ZIIP table contains the following columns:
|
Column Name |
SQL Data Type |
Nullable |
Description |
|---|---|---|---|
|
ENCLAVE_SECONDS
|
INTEGER |
No |
CA Datacom SMP SRBs run in an Enclave. This is the total CPU time (in seconds) that this SMP task has used for the life of this MUF. |
|
MUF_NAME |
CHAR(8) |
No |
Name of the MUF specified in the MUF Multi-User startup option or the MUF job name. |
|
SEQUENCE_NUMBER
|
SMALLINT |
No |
A sequence number that uniquely identifies the SMP task. For example, sequence number 1 is the first SMP task, sequence number 2 is the second SMP task, and so on. |
|
ZIIP_ON_CP_SECONDS
|
INTEGER |
No |
If the ZIIP Multi-User startup option was specified for this SMP subtask, this is the total CPU seconds spent on a standard (non-zIIP) processor that would have run on a zIIP processor but a zIIP processor was not available. If the ZIIP Multi-User startup option was not specified, this column is 0 (zero). |
|
ZIIP_PERCENT
|
SMALLINT |
No |
This is 100 if no user limit has been placed on zIIP processing with the ZIIP_USER_LIMIT Multi-User startup option. Otherwise, this is the user-specified limit. |
|
ZIIP_QUAL_SECONDS
|
INTEGER |
No |
The total time in seconds for which this SMP subtask was qualified to run on a zIIP processor. |
|
ZIIP_SECONDS
|
INTEGER |
No |
The actual total CPU time this SMP subtask ran on a zIIP processor. |
