Counter type: Busy.
UCL-LOCK-MAX
(Legacy Style only) No longer used.
UCL-LOCK-QTIME
(Legacy Style only) No longer used.
UCL-MAX
(Legacy Style only)
In Measure G10 and later PVUs, zero.
In Measure G09 and earlier PVUs, maximum number of items on the queue described by the
UCL-QTIME counter.
Counter type: Max queue.
UCL-QTIME
(Legacy Style only) In Measure G10 and later PVUs, zero. For the nearest equivalent, see
PRES-PAGES-QTIME (page 305), which includes user code and data frames, as well as system code
and data frames that this process has caused to be present in memory.
In Measure G09 and earlier PVUs, the time that user code and library pages were mapped. This
counter is a subset of (not an addition to) the PRES-PAGES-QTIME counter.
With REPORT RATE OFF, this counter is the total queue time for the memory category. With REPORT
RATE ON, this counter is the average number of UCL pages.
You can get process data page information by subtracting UCL-QTIME (total code and library
pages) from PRES-PAGES-QTIME (the total of all pages mapped for the process.
Counter type: Queue.
Usage Note for All PROCESS Entities
For information on how processes are dispatched, when they are executed, and so on, see the
appropriate system description manual.
Usage Notes for J-Series PROCESS Entities
• In J06.13 and later RVUs, it is possible to dynamically increase the number of enabled
IPUs/CPU. PROCESS measurements that span a change in IPUs/CPU will contain the initial
IPUs count.
Usage Notes for H-Series and J-Series PROCESS Entities
• Process priorities can change during process execution. Tracking process priorities in a
measurement allows Measure clients to view, by PROCESS entity, the priority for a particular
process or set of processes at the start and end of a measurement interval and can be helpful
in tuning an application. In H06.25/J06.14 and later RVUs, two sets of PROCESS entity
counters are implemented to track process priority changes during a measurement:
INITIAL-PRIORITY-START and INITIAL-PRIORITY-END, and CURRENT-PRIORITY-START and
CURRENT-PRIORITY-END.
◦ The INITIAL-PRIORITY-START and INITIAL-PRIORITY-END snapshot counters reflect the
target (requested) priority of a process at the start and end of a measurement interval.
The initial priority can be changed during process execution by using the ALTPRI TACL
command, or the ALTERPRIORITY, PRIORITY or PROCESS_SETINFO_ Guardian procedures.
For example: a process that was launched with a priority of 100 is said to have an initial
