Application Performance Analyzer for z/OS, Version 11.1, Customization Guide

Customizing Application Performance Analyzer for use with J9VM

This chapter describes the tasks for configuring the optional J9VM support. These tasks are only required if you want Application Performance Analyzer to measure Java applications running under the IBM® J9VM.

Work closely with a security administrator and a USS administrator to complete the following tasks:

  1. Install USS files in an Application Performance Analyzer directory on your system
  2. Provide APF authorization for the Application Performance Analyzer USS files
  3. Assign USS permissions to the Application Performance Analyzer started task
  4. Set up Security Access Rules
  5. Update the started task configuration settings
  6. Enable Java late attach API

Application Performance Analyzer can be configured to support either 31-bit or 64-bit Java in the started task. Regardless of how it is configured, Application Performance Analyzer can sample both 31-bit Java applications and 64-bit Java applications, with the appropriate Java PTFs installed on your system.
