Change the UME source system for AS Java ?

[symon_braunbaer]

Hello,

sorry, but a quick google search didn't return any reasonable results, so I decided to quickly ask...

We have a Java system, which has its UME user store in an ABAP system.
Now our functional guys have asked us to disconnect the Java system and connect it to another

ABAP system, meaning it will use the user store of another ABAP system, usage type ERP.
Is that even possible ? If yes, kindly guide me how exactly to do that...

Thanks a lot !!

Hello Symon

There is a document written by for UME switch.

You may refer that to reconfigure the system to connect to a new ABAP stack as UME.

Possibly he can give you extra inputs in your case.

Hello Reagan and thanks a lot for your reply!

A brief google research already brought me to that document yesterday! I have modified the UMEBackendConnection RFC destiination, as this document advises and it was a disaster... Nobody could login anymore to the Java instance! I have tried to activate the emergency user sap*, as described here:

http://help.sap.com/saphelp_nw73/helpdata/en/a2/03aa3d5acd40f082db65ee59c360b7/content.htm

But there was no com.sap.security.core.ume.service under the cluster config menu !!! I found it under templates and under instance. Under instance it could not be modified, so I modified it under template, but again after restarting the Java instance, it was not possible to login! So finally I have restored the system !!! I have opened a high priority OSS message with SAP as well!
