Re: Java - 6

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.

Have a question relating to Java on the system.
I'm at 7.1 and my (boss) wants to go ahead and
remove Java 6 on our development box and see what happens.
We've got 7 & 8 on it and while I realize that
when we move to 7.3 (next month) that won't matter but
his question is what's going to happen to our system now?
How much "stuff" relies on 6 and why can't we just move to 7 or 8?
