Customizing the version of Java on z/OS

Check the version of Java™ in your enterprise, and change it, if necessary.

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

For information about the levels of Java that IBM® Integration Bus supports, see IBM Integration Bus Requirements. The 64 bit version of Java is required.

To check the current version of Java in a broker component, complete the following steps.

Change to the bin directory in which you installed your Java product.
For example, if Java is installed in /usr/lpp/java, change to the /usr/lpp/java/bin directory, and type ./java -fullversion.
You receive the following response, or a response with similar content:
```
java version "1.6.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.6.0)
Classic VM (build 1.6.0 J2RE 1.6.0 IBM z/OS Persistent Reusable VM build cm142-20040917
 (JIT enabled: jitc))
```
The response in this example confirms that Java 1.6.0 is the current version, which is the minimum level required for this platform.
If you want to set, or change, the current Java version, edit JAVAHOME in the broker profile (BIPBPROF).
For further details about the broker profile, see Creating a broker on z/OS.
Run BIPGEN to re-create the broker ENVFILE and any integration server specific ENVFILEs
Restart the broker to pick up changes to the ENVFILE.
