Re: Java - 6

[Pete Helgren <pete@xxxxxxxxxx>]

Steve weighed in already and I'll add this:

In many cases, setting the default JVM for your system won't break 
things.  In most cases, the JVM's will be backward compatible.  YMMV...

So you could switch the system default JVM to start.  Good article here: 
http://www-01.ibm.com/support/docview.wss?uid=nas8N1019917 ; Where the 
removal of an JVM LPP would come back to haunt you is where you have set 
the JAVA_HOME environment variable or specifically added the JVM to your 
PATH. Once the JVM is gone, your program(s) will stop working.  But if 
most of the programs just grab whatever JVM is the default, then 
switching them shouldn't be difficult or catastrophic.

Using wrkjvmjob is a good idea.  You can see how the jobs are started 
and figure out how best to modify their startup parameters if 
necessary.  I have been fairly successful switching default JVM's 
without breaking existing JVM based programs.  However, you may want to 
make sure you are current on PTF's for the VRM level you are running 
*just* in case there was something dependent on the installed JVM versions.
