Re: Prevent JVM from starting again and again

Sure, I tried using RUNJVA interactively and I found passing parameter to
be cumbersome... seems it does not like parameter length above 256 chars?
Anyways, do you mean you are calling Java methods/class within RPGLE and
its not causing new JVM to be started? I am thinking to implement it as
last resort... appreciate your reply...

FWIW, the RUNJVA CL command can run Java apps and could probably be
substituted for QSH. I haven't used RUNJVA since 7.1 (or earlier), but
when I did it started a new JVM for every call.

We're an RPG shop, so I'd just write an RPG program that would call all
the Java apps, and that would reuse the same JVM. I can't say about an OS
command/API, since I've never needed one.

Subject: Prevent JVM from starting again and again

Hi Group,

I am calling Java class in a CL program using QSH command... it seems its
starting JVM for each call which is not so good for performance, is there a
way to prevent this so JVM is started once and then all future call is
handled by started JVM instance? Also, when CL is called interactively it
will mandatory ask for ENTER to close the QSH session, can this be
prevented? Appreciate any help !

Regards,
M
