Hi,
I am a SAP newbie.
I have EP on a standalone Java (I implemented the EP using rapid installer), and right now, it is using the file dataSourceConfiguration_database_only.xml as its datasource configuration. I want to change the datasource to an existing ABAP system. However, this existing ABAP system has a ASJava-Addin (BW was installed on this ABAP). If I want to use different users for each of the two Java systems, how should I deal with the communication, administrator, and guest users on both of the J2EE engines? (ie. Do I need to change the admin and guest usernames (ie. j2ee_admin) for the portal to avoid conflicting with that of the Java-Addin for the ABAP? How do I change the j2ee adminstrator username btw? And if I were to change it, do I need to change it in other places as well, such as in the connection factories of the default JMS provider?)
Thanks for all your help, this is quite urgent, and points will be awarded
