RE: java 6 use

Mike-

The V7.3 memo to users has instructions on upgrading WebSphere applications to use the Java of your choice (7 or 8, 16 or 32). If you have upgraded WebSphere to v8.5.5.10 before you upgrade OS from 7.1 to 7.3 be sure you read the instructions in the memo to users-- you have to run a migration procedure or WebSphere won't run. Ask me how I know...

Thanks for the tip on WRKJVMJOB. That shows that all of the currently running java apps are using 1.6 or 1.7 and all the 1.6 jobs are from IBM so I would assume a move to V7.3 would update those to use 1.7 or newer. But it does not show those apps called from RPG that might only exist for a few minutes. I looked at the RPG code we use to execute java from RPG and they do not currently do anything to specify which JVM to use so I would assume they are using the default which is currently 1.6. We could just change the current default to 1.7 and see what happens but that might have a negative impact on production work. Is setting the JAVA_HOME Environment variable in the RPG code the best method for pointing this kind of hybrid app (RPG+Java) to the JVM to use for that specific job?

We are running V7.1 and starting the planning to go to V7.3 We currently
have java 5, 6 and 7(32 but) and 7(64 bit) installed on our system. We
know that Java 5 and 6 are not supported on V7.3 Websphere is currently
configured to use Java 7. Our global environment is set to Java 6 (1.6.0)
when running java *version. We do run some java code outside of Websphere
called from RPG programs and we have some 3rd party java apps that do not
run in Websphere. Is there some way we can find out what java apps are
using what version of java so we know what we need to worry about getting
upgraded to use java 7 or 8?

Thanks
