ERXT0313/EZXT0313: Address Space zAAP CPU Activity

This report provides an address space perspective of zAAP processor usage by zIIP and by program name.

zAAP processors offload JAVA functions to a specialized processor. The report shows how effectively zAAP processors are being used by address spaces that utilize the specialized processing unit. This report can also be used to evaluate how much workload is zAAP-eligible to determine if it would be beneficial to redirect activity to zAAP processors.

• The first three numeric columns refer to processing that takes place on a standard (CP) processor. If zAAP eligible processing is a large proportion of total CP processing, see if you need to add zAAP capacity.
• The next two columns show zAAP activity on installed zAAP processors.
• The last column is an estimate of how efficiently the JAVA workload was offloaded to zAAP processors:
  • A high percentage means zAAP capacity is adequate.
  • A low percentage, along with high zAAP eligible work executing on a CP, means that zAAP capacity is not optimal.
