increasing heapsize of java on WINDOWS 2003


Hi SAP gurus,

I have been asking almost on all forums and sap tech support and so far haven't recieved any solution.

I have installed SAP server (XI, CRM, EP) and everything went well except at the end I am not able to start the SAP Processes completely. J2EE process of SAPMMC stays yellow. SAP tech support suggested that I should increase the Heap Size from 1024 to 2048.

I am using Windows 2003 (64 Bit) and I couldn't find any place (even on control panel as suggested by many) where I can change this.

Another suggestion was to start Java manually as follows

java -Xmx2048m bla bla bla......

But to do this I have to give the right jar file also along with this command and I don't know which jar file SAP is using since it is done automatically.

If some one can please help me by letting me know where I can change the heap size for java on WINDOWS 2003 (64bit) I would really appreciate.

Thanks a lot in advance
