New BW 7.0 System (ABAP+Java) as two single-stack Systems? How?

22 Views

Hello,

as of the current recommendation not to install a dual-stack system anymore, we are planning to setting up our new BW 7.0 sandbox-system as two single-stacks.

In my understanding, I have two install two separate systems (1. AS ABAP, 2. AS JAVA) and connect them each other. So each system should have it's own SID?

Procedure: I first have to setup the AS ABAP with SID=NWA and then afterwards setup the AS JAVA with SID=NWJ - and connect each other afterwards (e.g. RSPOR_SETUP and so on...).

Or am I allowed to use the same SID(=NWA) also for the AS JAVA (as it is in a dual-stack installation)? If so, am I allowed to use the same system (OS will be windows 2008) for them? In the Installation Guide I found for NW 7.0 EhP2, they still mention the dual-stack installation...

So, if you have a dual-stack installation, it looks like this:

Host: nw.sap.company.local / SID: NWA, Instance: 00 (AS ABAP) + NWA, Instance: 00 (AS JAVA)

How should it look now? Like this:

1. Host: nw.sap.company.local / SID: NWA, Instance: 00 (AS ABAP) + NWJ, Instance: 00 (AS JAVA)

2. Host: nw.sap.company.local / SID: NWA, Instance: 00 (AS ABAP) + NWJ, Instance: 01 (AS JAVA)

3. Host: nwa.sap.company.local / SID: NWA, Instance: 00 (AS ABAP)

+ Host: nwj.sap.company.local / SID: NWJ, Instance: 00 (AS JAVA with EP_CORE, BI_JAVA, ...)

In case of option 3, do they have to use their own DBMS?

Thanks in advance!

BR,
