Weblogic monitoring on linux or java, any tool?

Hello people, i've just started to get involved into WebLogic server. This time is the 11.x version.
Yet, they put me in a position where i find the server crashing and with strange Oracle ADF errors.
So in order to actually help tune/optimize these applications i need a way to get how many resources are being used per each application. And another issue is that the garbage collector starts at a huge number (3gb) when we just turn on the app server. We're actually about going  crazy with this... heh
any help?

JROCKIT/SUN/IBM JDK?
What is the accurate version of weblogic (like 10.3.0.6)
What is exact version of JVM ( like 1.6.0_21)

Hey Gheist, thank you for your time.

The weblogic server
11g Release 1 (10.3.5)

and the JVM
1.7.0_51

We've got Jrockit but there is no usage per application. Actually it seems quite simple. Do you know if this tool could get improved by any script or anything?
Thanks in advance !!

Well it is not about scripts. Only way to get oversight of weblogic is oracle grid/cloud control (which in turn uses JMX behind the scenes)
1.7.0_51 oracle jdk or openjdk or ibm jdk?
(tuning differs greatly)
Once GC pause tuning cannot improve more, i;d suggest splitting web application in components running in reasonably sized multiple "servers".

is there much of a difference between them? we've got the Oracle JDK.

java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)

It actually says "SE" could THIS be the issue?

On the other hand, you seem quite involved into monitoring, could you please give a hint on wich tool use to achieve measuring use per application? than kyou!

It is much easier to re-deploy on new system. Patches are not so easy as it sounds.
