Hi guys, I have this memory exception( java.lang.OutOfMemoryError: PermGen space). I know I need to increase the memory size by altering the JAVA_OPT's -XX ermSize=128m -XX:MaxPermSize=196m parameters from the command line, but I use Tomcat 6.0 as a windows service, I want the changes to occur automatically instead of using the command prompt. Can somebody help me with this. Thanks, Samanth.
I want the changes to occur automatically instead of using the command prompt.
There is no way to change the any memory setting on the fly, it has to be done on starting the JVM. Exactly how to do this depends on how you are running Tomcat, I don't recall how to do it for Tomcat as a service, ask in the Tomcat forum.
I know that it could be done by setting ++JvmOptions="-XX:MaxPermSize=128m", but I was not sure where to do it whether in CATALINA_OPTS or JAVA_OPTS parameters in the catalina.bat and also I am not aware of how to it. Please let me know if you know something about it.
