Thanks for the replies... QIBM_QSH_CMD_OUTPUT surely does help... i am not
sure but I think I used it in past and I just forgot about it .... anyways,
I tried remodel my program so I am using a driver RPGLE reading a data
queue and then this RPGLE will call CL which in turn is calling QSH
command... seems its starting the JVM each and every time... comparing its
performance from interactive call of CL , I do not think its any benefit in
terms of performance.... any ideas if I call the Java class from driver
RPGLE will it help get any performance benefit?

Had the same problem here that the JVM is starting with every time I call
the command (its not really a problem because that is what is supposed to
happen: you call the program, the JVM starts, executes your program and
once its done, quits the VM again).

My “fix” for this problem was to change my program to start up once and
then scan a folder for a txt file that contains all the parameters that
would usually be handed over to the program. Once it detects a text file,
it opens a new thread to process it and once done, the thread is closed but
the program itself keeps running. This way it can also handle multiple
requests in parallel. The text file is created by the CL that would have
usually called my program before the fix.

I assume the correct solution would be to set something up like an
application server that runs your application and is then called by the CL
but no clue if that is

a) the correct approach and
b) how to do that ;)

Hope that helps!
