Hello Gurus,
I recently noticed while trying to do an OS Migration that our BI Production[ ABAP+Java ] stack is not in synch with our BI Development & BI Quality.
Before I joined , the earlier consultant had built the BI Development system as a Pure ABAP stack, Though at the DB level I can see both the ABAP and Java schemas. Also luckily / unluckily for us, the Java stack is not used at all in the BI team.
Kindly note that once the BI DEV /QA systems are in sych with the BI Prod , we intend to perform the Dual Stack Splitting using the Dual Stack Split Tool [SWPM] before we perform an OS Migration, so eventually we would be only doing a ABAP stack OS Migration and since the Java stack is anyways not used, reinstall a fresh Java stack on the Migrated OS .
Here are the details for the Platform
BI Prod - ABAP+JAVA Stack
OS- Windows Server 2003
DB - Oracle 11.2.03 [ Upgraded 6 months back]
BI Dev - ABAP Stack
OS - Windows 2003
DB - 11.2.0.3
Since this particular BI Dev system is technically incorrectly built , Would like to rebuild this correctly to simulate the Dual Stack Split.
Please suggest if I am following the right approach or alternatively suggest a new method
1. Java Add On on existing ABAP BI DEV system - May not work as the existing Java schema at the OS level may get dropped ,
Also a Java Add On to an existing ABAP system may not be the same as a BI Dual stack system.
2. Perform a BI DEV rebuild as a dual stack system using a BI Prod Backup .
The System copy Tool [SWPM] does not support the windows 2003 OS , as it is lets you install /create new systems only on newer OS [win 2008 / win 2012] . So I tried using the old SAP system Copy tool - NW2004s(7.0) _Installation Master [ predecessor of SWPM], this works fine on the Windows 2003 and however this installer doesn’t recognize the Oracle 11g Oracle Home which I installed and only gives an option for the Oracle 10.2
This means we are in a sort of deadlock -
new SWPM tool – doesn’t work on the old Windows 2003 OS [ after OS rebuild on SBQ]
old BI_Inst_Master tool - Works with the OS windows 2003 , but doesn’t recognize the Oracle 11.2 , only gives option for Oracle 10.2 .
Additionally is our Migration approach of first Splitting the Dual stack system and then only Migrating the ABAP stack and then reinstalling the Java stack on the migrated OS feasible ?
Appreciate your help and patience.
Cheers
Prashant
