OutOfMemoryError while lookup jndi with launchClient

Hi

I'm encountering this weird situation. When i try to lookup JNDI using while using LaunchClient, i keep getting this error

javax.naming.NamingException: The JNDI operation "lookup"on the context "tibs-apps/nodes/apps/servers/server1" with the n
ame "jdbc/thedb" failed.  Please get the root cause Throwable contained in this NamingException for more information.  Root e
xception is

java.lang.OutOfMemoryError
        <<no stack trace available>>

By the way, this only happen when i try call my application using LaunchClient, the same methods is called in the web project, it's fine.

And i've tried it in my development server, it works. Just not working in my production server.


Any idea what is wrong?

mysterious OutOfMemory errors usually mean you have to increase the heap size on the JVM which is bombing, in this case on your production server.

Add a startup parameter from the admin console ... you can either add this manually to the startup arguments or go to the application server, yourServer, JVM settings.  There should be a minimum and maximum heap size setting fields there.  If you have to do it manually the command line is:

-Xms1000m -Xmx1000m

(just for example)

Xms means minimum heap size (at startup) in MB, which is really just for speed ... if you allocate the heap right away things will load faster.

Xmx means maximum heap size overall in MB.  This is the one you really want to increase if you think you're having a problem with heap.
