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

Overview

This panel allows you to specify information needed by the Source Program Mapping (SPM) feature for Java programs.

During the measurement, the measurement task determines and records source file names for each of the Java classes in which execution is observed. However, the source file names are not fully qualified. Use this panel to specify sequences of file name prefixes that will be concatenated as high level qualifiers to the captured source program file names in order to form fully qualified HFS path names.

The A03 panel lets you save a set of file name prefixes in an ordered list. Each name in the list is assigned a search sequence ("SrchSeq"): 01, 02, 03, etc.

Note:
It is helpful to think of the file name prefixes as directory names, and think of stored Java class source file names as files within these directories. Using this analogy, SPM tries to locate a Java class source file by searching each of these directories. It searches the directories in the sequence (01, 02, 03, etc.) indicated by the SrchSeq value.

You can store a default, global list of prefixes and you can store a list for a specific measurement. When attempting to resolve file names, SPM will search the directories specified for the particular measurement first, and then it will search the global list.

The Java source program mapping panel consists of two sections:

  1. An input area in which you specify a file name prefix to be added to a list, and an option specifying whether you are working with the global (default) list or the list for the current measurement.
  2. A scrollable list of file name prefixes. The list you are working with (current measurement or default) appears at the top of the list.

A sample Java source program mapping panel is shown here:
