The Values in EPAservice.conf  max and min   java parameters  are NOT picking  up 

but it shows  initial value only (512m)  on ps -ef | grep java 

Only want to allocate a Max value of 1024m  to the Agent 

 

 

Environment

Release : 10.7.0

Resolution

Resident memory in top and heap memory in Investigator  shows only 500 MB of resident memory being used. So  Xms/Xmx is used to configure the Heap size, which is part of Resident memory. We can not configure either Resident/Virtual memory size from a java app.

The Resident memory tells how much physical memory (RAM) a process is using, while the Virtual memory tells how much memory a process thinks it’s using, so it's usually not a indication of resource usage.
