All, I am trying to adjust our application's memory settings: JVM and Heap adjustments. I also came across -XX:MaxNewSize parameter. Our application runs on a AIX machine which has ample RAM (100+ GB). 1200 concurrent users. Deployed in WAS 6.1
My question is: -XX:MaxNewSize - What is this param used for? Is this parameter applicable for AIX? I also need some assistance in increasing JVM size (-XX:MaxPermSize param). Our current value is 256 MB. For an application which has peak load of about 1300 concurrent users, do we need to increase this param to 512 MB? Reason is our application nodes go down due to out of memory issues. Out max and min heap size is 1.5 GB
Edit: Also, if you could provide JVM memory architecture, it would be even more helpful.
Thanks!
