HiperDispatch Management attributes
This attribute group provides information about the weight and status of a logical processor when the LPAR is in HiperDispatch mode.
CPU Type The type of processor. A valid value is an integer. Values appear on the workspace as follows:
- 0 = Standard. A standard processor
- 2 = 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).
- 5 = zIIP. zSeries Integrated Information Processor, a special class of assist processor used mostly for DB2 workloads.
Current Weight The current weight for logical processors of this type in this LPAR. A valid value is an integer. The range for this value is from 0 to 999 for shared processors.
Values appear on the workspace as follows:- -1 = Undefined
- 65535 = Dedicated
HiperDispatch Management The status of the HiperDispatch feature. A valid value is an integer. Values appear on the workspace as follows:
- 0 = Unavailable. Either the required hardware is not installed or the operating system does not support it.
- 1 = On. This LPAR is in HiperDispatch management mode.
- 2 = Off. This LPAR is not in HiperDispatch management mode. Either HiperDispatch management mode has not been enabled in the SYS1.PARMLIB, or the LPAR does not have enough work to warrant its use.
HiperDispatch Priority The HiperDispatch priority of work dispatched on the logical processor. A valid value is an integer. Values appear on the workspace as follows:
- 1 = High. 90% of the processor's execution time is spent running high priority work.
- 2 = Medium. 90% of the processor's execution time is spent running either high or medium priority work.
- 3 = Low. All other processors.
LCPU ID The identifier of the logical processor. A valid value is an integer. This is displayed as a hexadecimal value.
LCPU Thread The Multi-Threading thread number. Expected value is 0 or 1 for zIIP processors. A valid value is an integer. The range for this value is from 0 to 9.
LPAR Cluster The name of the cluster to which the LPAR belongs, as defined in the hardware console. LPARs that are members of the same cluster may share central processor and channel resources through the Intelligent Resource Director. A valid value is a string of up to 8 characters.
LPAR Group The name of the group to which the LPAR belongs, as defined in the hardware console. LPARs in the same group may have a group capacity defined. The sum of 4-hour rolling MSUs for the group may not exceed the group capacity. LPARs may also have individual capacity limits. An LPAR could be capped if either its individual limit is reached or the group total is reached. A valid value is a string of up to 8 characters.
LPAR Name The name of the logical partiation (LPAR), as defined in the hardware console. A valid value is a string of up to 8 characters.
Managed System z/OS operating system in your enterprise that an OMEGAMON for z/OS agent is monitoring. A valid value is a string of up to 32 characters.
Management Percent The percentage of physical processor time spent in this logical processor managing this LPAR. A valid value is a number to three decimal places accuracy. The range for this value is from 0 to 100.000.
Maximum Weight The maximum weight that can be assigned to the set of logical CPUs of the associated type within the logical partition. A valid value is an integer. The value is 0 when no maximum weight was specified. The range is 0 to 999 for shared processors, unless the LPAR uses dedicated CPs, in which case the value is 65,535 which is displayed as "Dedicated". If the associated processor type is not used in the LPAR, the value is -1 which is displayed as "Undefined". Values appear on the workspace as follows:
- -1 = Undefined
- 65535 = Dedicated
Measurement Interval The time in seconds to thousandth of a second over which this observation is calculated. A valid value is a number to three decimal places accuracy.
Minimum Weight The minimum weight that can be assigned to the set of logical processors of the associated type within the logical partition. A valid value is an integer. The value is 0 when no minimum weight was specified. The range is 0 to 999 for shared processors, unless the LPAR uses dedicated CPs, in which case the value is 65,535 which is displayed as "Dedicated". If the associated processor type is not used in the LPAR, the value is -1 which is displayed as "Undefined".
Values appear on the workspace as follows:- -1 = Undefined
- 65535 = Dedicated
MVS Pct The percentage of time that a physical processor was dispatched to this logical processor as viewed by z/OS. A valid value is a number to three decimal places accuracy. The range for this value is from 0 to 100.000. The value is calculated as:
MVS Pct = (Online Time - (Wait Time + Parked Time) * 100,000)/(Online Time - Parked Time)
Where: Wait Time = LCCAWTIM, Parked Time = LCCX_TimeParked, and Online Time = logical processor online time as observed by PR/SM and returned by Diagnose 204.
Parked Pct The percentage of time that a logical processor was parked by HiperDispatch. A valid value is a number to three decimal places accuracy. The value is calculated as:
Parked Pct = (Parked Time * 100,000) / Online Time
Where: Online Time = logical processor online time as observed by PR/SM and returned by Diagnose 204.
Physical CP Dispatch Pct The percentage of time that a physical processor was dispatched to this logical processor. A valid value is a number to three decimal places accuracy. The range for this value is from 0 to 100.000.
Processor Type The type of logical processor. A valid value is an integer. Values appear on the workspace as follows:
- 0 = Standard. A standard processor
- 2 = 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).
- 5 = zIIP. zSeries Integrated Information Processor, a special class of assist processor used mostly for DB2 workloads.
Share Percent The percentage of a physical processor that the logical processors are entitled to receive. For HiperDispatch, High-priority logical processors the value should be 100%. Low priority logical processors the value should be 0%. Medium priority logical processors will have a share percentage proportional to their Polar Weight. A valid value is a number to one decimal place accuracy. The range for this value is from 0 to 100.0.
Status The status of the logical processor. A valid value is an integer. Values appear on the workspace as follows:
- 1 = Online. The logical processor is configured and allowed to have work dispatched on it.
- 2 = 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.
- 3 = 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.
- 4 = Park Pending. The logical processor is in the process of being parked.
- 5 = Reserved. The logical processor is configured but has never been brought online.
System MVS Pct The MVS percentage across all online standard logical processors in the LPAR. A valid value is a number to three decimal places accuracy. The range for this value is from 0 to 100.000. A value of -1 indicates "Unavailable". All 3 times are the sum of the values for all logical processors in the LPAR. The value is calculated as:
System MVS Pct = (Online Time - (Wait Time + Parked Time) * 100,000)/(Online Time - Parked Time)
Where: Wait Time = LCCAWTIM, Parked Time = LCCX_TimeParked, and Online Time = logical processor online time as observed by PR/SM and returned by Diagnose 204.
System PCPD Pct The physical CPU percentage across all online standard logical processors in the LPAR. A valid value is a number to three decimal places accuracy. The range for this value is from 0 to 100.000. A value of -1 indicates "Unavailable".
