Address Space IA Impact attributes

Use the Address Space IA Impact attributes to determine how various workloads within your system may be interfering with each other. Impact analysis assists you in arriving at quick and accurate solutions to problems caused by workload contention.

ASID The address space ID, in hexadecimal, of the impactor. The address space ID is a unique number assigned to an address space when it is created. It is used by z/OS as an index to find the main control block of the address space or to differentiate between address spaces. A valid value is an integer, displayed as a hexadecimal string.

CPU Percent The percentage of the total delay to the favored workload that this impactor contributed during the collection period that resulted from CPU contention. A valid value is a number to two decimal places accuracy. The range for this value is from 0 to 100.00.

Enqueue Percent The percentage of the total delay to the favored workload that this impactor contributed during the collection period that resulted from waiting for an enqueue. A valid value is a number to two decimal places accuracy. The range for this value is from 0 to 100.00.

Favored ASID The address space ID, in hexadecimal, of the favored address space. A valid value is an integer, displayed as a hexadecimal string.

Favored Job Name The job name of the favored address space. A valid value is a string of up to 8 characters.

Favored Type The type of the favored address space. The value in this column should be AS, identifying this as an address space. A valid value is a string of up to 2 characters.

I/O Percent The percentage of the total delay to the favored address space that this impactor contributed during the collection period that resulted from I/O contention. A valid value is a number to two decimal places accuracy. The range for this value is from 0 to 100.00.

Impact Percent The percentage of the total delay, for any reason, to the favored workload that this impactor contributed during the collection period. A valid value is a number to two decimal places accuracy. The range for this value is from 0 to 100.00.

Impactor zCBP/zAAP on CP Count The number of samples that this impactor has delayed the favored address space during the collection period for which the delay was due to zCBP/zAAP on CP contention. A valid value is an integer.

Impactor zIIP Count The number of samples that this impactor has delayed the favored address space during the collection period for which the delay was due to contention for System z Integrated Information Processor resources. A valid value is an integer.

Impactor zIIP on CP Count The number of samples that this impactor has delayed the favored address space during the collection period for which the delay was due to SUP on CP contention. A valid value is an integer.

Job Name The job name of the impactor that is delaying the favored workload. A valid value is a string of up to 8 characters.

Job Number The JES job identifier of the impactor. A valid value is a string of up to 8 characters.

Managed System The 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.

Performance Index The performance index defined for the impactor's service class. A valid value is an integer.

Service Class The name of the service class in which the impactor is running. A valid value is a string of up to 8 characters.

Total CPU Count The total number of samples that have been taken for the favored address space during the collection period for which the delay was due to CPU contention. A valid value is an integer.

Total Enq Count The number of the total samples that have been taken for the favored address space during the collection period for which the delay was due to waiting for an enqueue. A valid value is an integer.
