HiperDispatch Logical Processors attributes

The HiperDispatch Logical Processors attributes show the processor type and HiperDispatch statistics like priority, share percentage, and status for each processor configured in an LPAR.

CPU Type Type of processor. The possible values are:

  • Standard. A standard processor
  • zAAP. zSeries Application Assist Processor, a special class of assist processor designed to run Java workloads. For reporting purposes, a zAAP is sometimes referred to as an integrated facility for applications (IFA).
  • zIIP. zSeries Integrated Information Processor, a special class of assist processor used mostly for DB2 workloads.

HiperDispatch Priority The HiperDispatch priority of work dispatched on the logical processor. The possible values are:

  • High. 90% of the processor’s execution time is spent running high priority work.
  • Medium. 90% of the processor’s execution time is spent running either high or medium priority work.
  • Low. All other processors.

LCPU ID ID of the logical processor. This is a hexadecimal formatted value.

LCPU Thread The zero-based thread number representing a logical CPU running on the logical core.

Managed System Name of the managed system where this data is collected. It has the format <plexname>:<smfid>:MVSSYS, where plexname is the sysplex this LPAR resides in and smfid is the name of the system management facility for this LPAR.

Management Percent The percentage of physical processor time spent in this logical processor managing this LPAR, formatted to three decimal places.

MVS Pct Logical processor MVS percentage (online time minus wait time and parked time).

Parked Pct Logical processor parked percentage.

Physical CP Dispatch Pct The percentage of time that a physical processor was dispatched to this logical processor, formatted to three decimal places.

Share Percent The percentage of a physical processor that the logical processors are entitled to receive, formatted to 1 decimal place. For HiperDispatch, High-priority logical processors this should be 100%. Low priority logical processors should be 0%. Medium priority logical processors will have a share percentage proportional to their Polar Weight.

Status Status of the logical processor. The possible values are:

  • Online. The logical processor is configured and allowed to have work dispatched on it.
  • Offline. The logical processor is configured but is currently not available for work to be dispatched. Intelligent Resource Director has likely reduced the relative weight of this partition in favor of other partitions.
  • Parked. This logical processor is configured online but will not dispatch any work. The processor can be unparked under the right conditions and start dispatching work for this LPAR.
  • Park Pending. The logical processor is in the process of being parked.
  • Reserved. The logical processor is configured but has never been brought online.

Total Warning Track Reqs The total number of warning track requests over the monitoring interval. This is the sum of the successful and unsuccessful warning track requests over the monitoring interval.

Warning Track % Successful The percent of warning track requests that were successful over the monitoring interval.

Warning Track Time The total number of seconds that this logical CPU was returned to the hardware for warning track over the monitoring interval.
