Address Space CPU Utilization attributes

The Address Space CPU Utilization attribute group provides basic address space identifying information and CPU usage information for all address spaces. It also provides enclave data.

JESJOBID The JES job ID of the address space. This column can be blank if the address space is not using JES services. (Note that tasks started using SUB=MSTR generally will not be using JES services and therefore will not have a JESJOBID. Address spaces started prior to JES initialization will generally not use JES services. However, a JESJOBID commonly does exist for the Master Scheduler, since it uses a JES service for SYSLOG.) Valid value is a string, with a maximum of eight characters.

Job Additional SRB Service Percent Cumulative additional SRB service percentage, to one decimal place, for the address space since collection started. This is (Job_Additional_SRB_Service_Time x 1000) / Job_Elapsed_Time. Since multiple CPs may be active, this value can exceed 100%.

Job Additional SRB Service Time Cumulative additional SRB service time (ASST) in seconds with two decimal places for the address space since it started. CPU time is accumulated here for this address space's preemptable SRBs and for client related SRBs for which this address space is the client.

The CPU time for all types of preemptable SRBs (PSRB, CRSRB, ESRB) executing within this address space as their home space is accumulated here. CPU time is accumulated here for SRBs dispatched in this address space on behalf of a client address space.
