Dual Stack NW installation with UME as R/3 System(ABAP only)

[Former Member]

I have a quick question guys. I am about to install a dual stack NW system with ADS(SQL server database on windows) and will use a R/3 Enterprise running on unix as the UME datasource. Now this R/3 enterprise backend already acts as bakend for Portal system and uses sap logon tickets and as such already has the user SAPJSF. Now when i actually perform the NW 7.0 installation and enter a master password during the course, would this override the SAPJSF user in R/3 backend system at all.

What are the general problems that are caused with using an existing ABAP only system as the UME for your Java stack(Dual stack actually) systems. Can you advise.

We recommend adding the SID to the name of these users for UME-ABAP connections.

SAPJSF_SID

J2EEADMIN_SID

J2EEGUEST_SID

Then it is clear which Java system is making changes to the AS ABAP. Otherwise you could run into auditing problems.

Hello Kalyan,

I don't see any problem on using an ABAP datasource for two different AS Java. The unique constraint is regarding the passwords of J2EE_ADMIN and SAPJSF, that will be the same on both systems.

Other option for this environment is creating a new client on ABAP backend for the brand new system you are installing.

Kind regards,
