Check the version of Java™ in
your enterprise, and change it, if necessary.
About this task
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 system requirements. The 64 bit version of Java is required.
To
check the current version of Java in
an integration node component, complete the following steps.
Procedure
- 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 "1.7.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.7.0)
Classic VM (build 1.7.0 J2RE 1.7.0 IBM z/OS Persistent Reusable VM build cm142-20040917
(JIT enabled: jitc))
The response in this example
confirms that Java 1.7.0 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 integration node profile (BIPBPROF
).
- Run
BIPGEN
to re-create the
integration node ENVFILE
and any integration server
specific ENVFILEs
- Restart the integration node to pick up changes
to the
ENVFILE
.
