Customizing the level of Java on z/OS
This task is part of the larger task of
customizing your z/OS environment.
WebSphere Message Broker supports
Java version 5 (SR3) (also known as Java 1.5.) You can customize your environment
to use either version.
Enter the following command from an OMVS window to check the current
version of Java:
java -version
Enter the following command from an OMVS window to check the current
version of Java:
java -version
You 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.
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.
