Customizing the level of Java on z/OS

This task is part of the larger task of customizing your z/OS environment.

Start of changeWebSphere Message Broker supports Java version 5 (SR3) (also known as Java 1.5.) You can customize your environment to use either version.End of change

  1. Enter the following command from an OMVS window to check the current version of Java:
    java -version
  2. Enter the following command from an OMVS window to check the current version of Java:
    java -version
    Start of changeYou receive a response similar to the following:
    java version "1.5.0"
    Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0)
    Classic VM (build 1.5.0 J2RE 1.5.0 IBM z/OS Persistent Reusable VM build cm142-20040917
     (JIT enabled: jitc))
    The response in this example confirms that Java 1.5.0 is the current version. which is the minimum required level for this platform.End of change
  3. If you want to change the current Java version, edit the profile for the component (BIPBPROF for a broker, BIPUPROF for a User Name Server, BIPCPROF for a Configuration Manager). Because the version of Java used is defined in the component profile, you can specify a different version for each component. For further details about component profiles, see Creating WebSphere Message Broker components on z/OS.
