Depends on how you're starting Geronimo.

1) or run/etc

    a) JAVA_OPTS environment variable:

         JAVA_OPTS="-Xmx256m -XX:MaxPermSize=128m -XX: 
+HeapDumpOnOutOfMemoryError" ./bin/ run

    b) and/or create bin/ (or .bat) file. Contents (for .sh)  
could look like:

         if [ -z "$JAVA_OPTS" ]; then
            JAVA_OPTS="-Xmx256m -XX:MaxPermSize=128m -XX: 

2) start-server or gsh geronimo/start-server

     a) edit etc/rc.d/start-server,default.groovy:

         // Append some reasonable java flags if none were configured  
         if (command.javaFlags.empty) {
             command.javaFlags << '-Xmx256m'
             command.javaFlags << '-XX:MaxPermSize=128m'
             command.javaFlags << '-XX:+HeapDumpOnOutOfMemoryError'

     b) or use -J flag:

         ./bin/gsh geronimo/start-server  -J -Xmx256m -J - 
XX:MaxPermSize=128m -J -XX:+HeapDumpOnOutOfMemoryError"
