6.4.2.6 CPU Time for USS Services

The CA MICS Batch and Operations Analyzer creates Unix System
Services (USS) individual process activity observations from
the Open Edition/MVS Process Section(s) of the SMF type 30
Common Address Space Work step and interval records (subtypes
2, 3, and 4).

The following CA MICS file contains USS process activity:

  File    File Label
  ------  --------------------------------------
  BATOEP  Open Edition/MVS Process Activity File

At the DETAIL time-span, BATOEP file may contain several
observations representing the resource usage for each
individual process utilizing Unix System Services.
Additionally, some observations contain resource usage for
child processes that are created by fork() and spawn()
functions.

CA MICS creates a separate observation in the BATOEP file for
each Open Edition/MVS Process section found in an SMF type 30
step or interval record.  The data elements required to
associate the parent and child processes are included in the
BATOEP file.

The following CPU time data elements represent the CPU time
used by USS processes during a step or interval:

o OEPUSSTM - USS CPU Time

  OEPUSSTM contains the contents of SMF type 30 field
  SMF30OST.

  It contains the TCB and SRB CPU time used by a process
  utilizing Unix System Services (USS).
