how to change JVM setting(-Xms-Xmx) of tomcat 5.0.19

[Ambily G Nair]

Hi

I am working on tomcat 5.0.19 server and I want to change the Heap size.I know that the command is JVM_OPTIONS="-Xincgc -Xms128m -Xmx256m" but I don't know how to use it and where we have put this change.I am looking forward for any help.


Thank you.

In Catalina.bat I find the note:

rem   JAVA_OPTS       (Optional) Java runtime options used when the "start",
rem                   "stop", or "run" command is executed.
  

But I don't find JVM_OPTIONS mentioned anywhere in my Tomcat 5 directory - in code or text file. Where did you find the information?
It appears that the installation did create some entries in the Registry, so I suspect thats where the parameter goes.
With a Google search I found this discussion.
If I were you I would certainly backup the registry before trying to fiddle with the settings.

what you should you do, is to:
- set the file $CATALINA_HOME/bin/catalina.bat
- look for JAVA_OPTS
- add -Xms128m -Xmx256m
my file contains this:

set JAVA_OPTS=%JAVA_OPTS% -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.util.logging.config.file="%CATALINA_BASE%\conf\logging.properties"
-Xms128m -Xmx256m
