[Socket-developers] JVM Heap Size Adjustment

[Rob G. <ro...@we...>]

Socketeers,

A quick heads up on adjusting the heap size for the JVM in tomcat.

1) vi /path/to/tomcat/bin/catalina.sh

2) At the top of the file, simply add some or all of the following
parameters, here's an example:-
        JAVA_OPTS="-server -Xms1500m -Xmx1500m -XX:NewSize=400m -XX:MaxNewSize=400m
 -XX:PermSize=128m -XX:MaxPermSize=196m -verbose:gc -XX:+PrintGCTimeStamps -XX:+PrintGCDetails
 -XX:+UseConcMarkSweepGC -XX:+UseParNewGC"

3) Restart tomcat, job done.

4) To check tomcat has picked these up, do:-

        ps -ef | grep java

cheers

Rob
