Change J2ee parameters on WAS 640-J2EE add in -config tool

Question

I have started the config tool to change java paramters per SAP.
However I notice that config tool shows dispatcher and server and below that an instance (xxx-318782 for example) which has a dispatcher and server also.....
Why is this and which do I modify to change java parameters?
Alos where can I find the setting, it is somewhere under services directory?
Thanks

Hi,
the dispatcher and server nodes that appear right below the root of the tree in the Config tool contain global properties (services and managers' properties). This means those properties are used globally instead of the default properties. For more info, refer to this page: http://help.sap.com/saphelp_nw04/helpdata/en/36/e71bbee9ab4677a744d4c4484b0bf4/frameset.htm
Next, the dispatcher and server you find under the instance xxx, are actually the elements that you've installed for your system. Changing a property on any of them applies locally, i.e. to the corresponding node (server or dispatcher).
To set java parameters, you need to click on the dispatcher or server (depending on which element's java props you need to modify). On the right side, under General tab you'll see the Java parameters field. Here is the relevant documentation: http://help.sap.com/saphelp_nw04/helpdata/en/39/7796e0a7be604ab63c2924045710a8/frameset.htm
Hope that helps!
