Re: length of time a java pgm runs in batch...
Hi Shane,
There's no time limit differences between batch and interactive. Ask
yourself the same question for, say, an RPG or CL program, and you'll get
the same answer in terms of basic system operation.
Hard to say what the problem is without seeing the code, but I
wouldn't
be surprised if it's a directory problem. If the timing is similar, the
output may not be where you expect it. That's a complete crystal ball
guess, and likely has the same level of reliability. You probably need to
send more detail to get a good answer.

Subject: length of time a java pgm runs in batch...
All:
I have a java program that is taking files from the IFS and putting them
in a zip file...if I run this interactively under QSH, it runs fine...it
takes a while, but it runs fine and does what I want it to do...However,
if I run this in batch, it says that it completes normally, but the
program doesn't zip up the files...it runs a while too but just doesn't
act like it wants to do what I tell it. Is there some limit on how long
a
Java program can run in batch as opposed to interactively? If so, what
can I change so that my program will run in batch?
