Re: Upgrading to Java 7 on IBM i

[Robert Rogerson <rrogerson@xxxxxxxxxxxxxxxxx>]

Thanks Justin.  Am I reading it right that when it mentions V6R1 it 
means V6R1 and later ?

I'm upgrading one application (GoAnwhere) which requires Java 7. And it 
requires you to manually change the JRE for it's job only. So I won't 
change the default version.  But my boss is concerned that installing 
the Java 7 license program may effect other applications.

From the link you sent I read this as saying the default java version 
will only change it if you manually change it as described in the link.  
So if I don't change the default then no other applications should fail.

Is this correct?

Thanks,

Robert Rogerson

I don't know the answer myself so I'm reaching out to this list as there is more than likely someone who can reassure me and give me a concrete answer.

My thought is that since there is no environment variable set at the system level there is no default being set.  And so, if there are java jobs being run they wouldn't be affected by the upgrade unless the setting of the CLASSPATH was manually changed for the job.
