There's almost no point in applying maintenance to Java. A single PTF replaces
the
entire contents. Just download / install whatever level you need. You can
still
use SMP/E if you desire, but I don't bother for the reason I just sited.
<soap box> SMP/E is a tool to keep track of maintenance and keep you (or the
vendor) from shooting yourself in the foot. It does nothing in regards to that
for Java. </soap box>
To test, just create a different mount point and have whatever user / process
that needs it set JAVA_HOME when they login or use .profile or create a
script or do "whatever" it takes to set the environment variables for
the software / user that needs it.
The example below is in my /etc/profile and is where I have 31bit Java V6,
but you can change JAVA_HOME to whatever mount point you create / mount
your new level. BTW, you may be able to tell from my example
that I keep a "system level" Java as part of the "version" sysres set,
so if I change the level, it goes in with rolling IPLs and nothing
is disturbed in the rest of the sysplex.
