RE: Optimizing Native Java

Aaron,

Joe mentions that CRTJVAPGM may not have been the way to go.

As far as giving the java process it's own memory...

AFAIK, that's done just like you would with any other i5 job.

Create a subsystem with it's own private pool for the job to run in.

HTH,

Subject: Optimizing Native Java

Hi All,
 
I am just completing a project where I wrote a Java proxy of 
sorts and there
were a bunch of third party jar files involved in the mix. To 
make a long
story short we are not satisfied with the performance we are 
getting out of
the Java processes on the iSeries (note the Java is running 
in it's own job
listening to a data queue - only one JVM startup).  We have run the
CRTJVAPGM against all .class and .jar files involved and are 
wondering are
there any other mechanisms to look at concerning getting more 
speed on the
Java end?
 
Obviously one solution would be to throw more memory at it, 
but is there a
way to section off the memory so this Java process gets sole use of it
(similar to how you can do the same for Websphere Application Server)?
 
Any other idea's?
