What does your main loop look like? Is it literally:

while (true)
(read contents of folder)
(check whether contents of folder have changed)

? With no delay in there? I would expect just slotting in a Thread.sleep
(30000); (if a 30 sec delay is acceptable) would reduce the CPU usage to 0%
during those 30 second wait periods?

Or if that doesn't help, on the SBMJOB command you could try running it
with a really low priority (say 95)?

Hope this helps,

Nigel Gay.

PM Never Ending Java Program

Please respond to
Java Programming
on and around the
iSeries / AS400

Hello All,
I'm just curious to see how others might be handling this.

I want to run a Java program in a batch job probably that will never end.
It's a directory listener that will listen for file additions and removals
from the directory.

I have ran it interactively and it was using about 120% of the CPU. In
it was around 11%.

Are any of you running never ending Java programs? Any suggestions on
optimizing it or a better way to run it?

Thanks in advance,
James R. Perkins
