Hi All,
We are facing frequent OOM issue in Production SOA server instances.
we have configured the JVM arug like below Is this the correct configuration or else any thing we need to add avoid frequent OOM error.
/usr/java/latest/bin/java -Dprogram.name=run.sh -server -Xms4096m -Xmx4096m -XX:PermSize=256m -XX:MaxPermSize=512m
Below restarting the server i have taken the Heap history.
Heap Configuration:
MinHeapFreeRatio = 40
MaxHeapFreeRatio = 70
MaxHeapSize = 4294967296 (4096.0MB)
