How to change JVM arguments for Jira?

[Serge Dukic]

Hi,

I'd like to change the Garbage Collection strategy used by our Jira instance (version 4.4.5). I've followed the instructions found here and added the following line to setenv.sh:

JAVA_OPTS="$JAVA_OPTS -XX:+UseConcMarkSweepGC"

However, after a restart the old Garbage Collection algorithm (UseParallelOldGC) is still being used.

How can you change the JVM arguments that Jira starts with?

Hi, I assume you are running this on Linux. Can you post the whole setenv.sh file where you've made the modifications? Also do you have any custom startup scripts?

After double checking the configuration, realised that I was modifying the wrong setenv.sh file. The file I was modifying belongs to a previous install of Jira and is not used by the startup script.
