Related to that statement, we've recently deployed a java application
that requires Java 5 on the 400 side and while it's available in V5R4,
it doesn't appear to be the default JVM.
We were hoping to just call the java classes we needed from an RPG
program, but we were worried about not knowing if the current JVM was
the 1.5 JVM; if something had already started a java app we'd be in a
1.4 JVM and fail. So we offloaded the java communication to a background
process and dataq-ed the communication back and forth. We also said to
ourselves "well, this saves the overhead of a jvm in each job." But we
said it w/out any good reason.
I know of many installations running JVMs on the System i, but they're
all in the context of a batch process app server (tomcat, websphere,
etc.) For those that are calling java programs from interactive jobs,
what's the performance like? Both from a first call (start JVM) and a
subsequent (active JVM) point of view? Is it something you'd want to do?
