HiperDispatch Management attributes

The HiperDispatch Management attributes provide information about the weight and status of a logical processor when the LPAR is in HiperDispatch mode.

CPU Type Type of processor. The possible values are:

Current Weight Current weight for logical processors of this type in this LPAR. The range is 0 – 999 for shared processors, unless the LPAR uses dedicated CPs, in which case the value is 65,535. If the associated processor type is not used in the LPAR, this value is shown as "undefined".

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

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

Logical Processor Type Type of logical processor. The possible values are:

HiperDispatch Management The status of the HiperDispatch feature. The possible values are:

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

LPAR Cluster 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.

LPAR Group 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.

LPAR Name Name of the logical processor, as defined in the hardware console.

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.

Maximum Weight Maximum weight that can be assigned to the set of logical CPUs of the associated type within the logical partition. The weight is in the range 0-999; except that it is 65,535 if the logical partition uses dedicated CPUs, and 0 if no maximum weight was specified. If this processor type is not present in this LPAR the weight is shown as "undefined".

Measurement Interval Formatted to 3 decimal places, this is the interval in seconds over which calculations were made for the data in this table. (Note: Seconds with 3 decimal places = the time in seconds to a thousandth of a second.)

Minimum Weight Minimum weight that can be assigned to the set of logical processors of the associated type within the logical partition. The weight is in the range 0-999, except that it is 65,535 if the logical partition uses dedicated CPUs, and 0 if no minimum weight was specified. If this processor type is not present in this LPAR the weight is shown as "undefined".

Management Percent Formatted to 3 decimal places, this is the percentage of physical processor time spent in this logical processor managing this LPAR.

MVS Pct Formatted to 3 decimal places, this is the percentage of time that a physical processor was dispatched to this logical processor as viewed by z/OS. The value is calculated as:
(Online Time - (Wait Time + Parked Time) * 100,000) 
MVS% = --------------------------------------------------- 
Online Time - Parked Time 
Wait Time = LCCAWTIM
Parked Time = LCCX_TimeParked 
Online Time = logical processor online time as observed by PR/SM and returned by Diagnose 204
Parked Pct Formatted to 3 decimal places, this is the percentage of time that a logical processor was parked by HiperDispatch. The value is calculated as:
Parked Time * 100,000
MVS% = ---------------------
Online Time

Parked Time = LCCX_TimeParked
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, 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:

System MVS Pct MVS percentage across all online standard logical processors in the LPAR.

System PCPD Pct Physical CPU Percentage across all online standard logical processors in the LPAR.
