Application Performance Analyzer for z/OS, Version 11.1, User's Guide

Variances

A percentage value is displayed under the heading "Variance" in various segments of this report. Its value quantifies the variance between a particular performance figure for the compared measurement and the corresponding value for the base measurement. A plus (+) value indicates a higher value than the base measurement and a minus (-) value indicates a lower value. The value is the percentage by which the compared measurement figure exceeds (+) or is less than (-) the corresponding base measurement value. Any value exceeding 999 percent is reported as "999%." The magnitude of the value is also represented graphically by a string of greater-than or less-than symbols.

Txn observations

This report segment displays the subsystem name and version of the CICS® subsystem being used, and compares the number of transactions sampled during the measurement sessions.

IMS Txns counted

This report segment compares the number of transactions counted during the measurement sessions.

Transaction rate

This report segment compares the transaction rate per second during the measurement sessions.

Txn throughput

This report segment compares the transaction throughput rate per second based on the number of transactions counted by the transaction service time.

IMS Txn svc time

This report segment compares the total service time while IMS transactions were active during the measurement sessions.

IMS Txn max svc

This report segment compares the longest running IMS transaction during the measurement sessions.

IMS Txn min svc

This report segment compares the shortest running IMS transaction during the measurement sessions.

IMS Txn CPU time

This report segment compares the total CPU time used by all IMS transactions during the measurement sessions.

IMS Txn max CPU

This report segment compares the highest CPU time for IMS transactions during the measurement sessions.

IMS Txn min CPU

This report segment compares the lowest CPU time for IMS transactions during the measurement sessions.
