I recently was modifying some of my server properties in Rational Application Developer to try and increase the memory of my JVM on startup. I forgot to take a backup before doing this, and by adding in an incorrect JVM variable, it seems I have broke my server in an unworking state. Whenever I try and startup my server to do any configuration changes, the JVM refuses to start with invalid params being passed in.
Is there a way to reset any JVM changes for WebSpehere Application Server v7.0 through the filesystem, or a way to do it without needing the server running already? I have been looking around in the wasProfile hoping to stumble onto a file where my settings ultimately live, but have had no luck.
It should be possible to write a wsadmin script to view/adjust the JVM options, but if you're on a non-z/OS platform, the fastest way to get back to working is probably to edit PROFILE_HOME/config/cells/CELL/nodes/NODE/servers/SERVER/server.xml; the JVM settings are typically written at the very end.
