Upgrade BW 7.00 -> BW 7.31

[Former Member]

Hi,

I have a specific question:we have only BW 7.00 ABAP installed and want to upgrade to BW 7.31.

After the upgrade can we still have only BW ABAP or must we also install BI Java?

In other words is BW 7.31 ABAP-only supported by SAP?

Thanks for your help.

Hi Fabio,

You can install seperate instance of Portal and integrate the same with BI 7.3 ABAP.

Thanks for your answer.

I don't want to use Java functionality, only ABAP.

Can I have a BW 7.31 ABAP-only system upgraded from BW 7.00 ABAP-only?

Is BI Java mandatory for BW 7.31?

Thanks a lot.

Hi

BI Java is optional, if you do not wish to use Bex Web you could run BI without it

Hello

The upgrade tool doesn't need a Java stack to upgrade the BW ABAP stack.

If you only have an ABAP stack then you don't need to worry about the Java part.

You can upgrade the BW ABAP stack to the 7.31 release.

SUM tool will identify the server as Dual stack.If you people are planning to upgrade only ABAP stack through SUM  please consider the following points.

1)Split the Dual stack through Dual stack split tool and install Java Part in other server

2)There're 2 steps of detection of JAVA stack.                              

To consider that the J2EE stack is removed, the parameter                 

rdisp/j2ee_start                                                          

must be set to 0 in the instance profile. Make sure        

this parameter is set properly and restart the instance for it to take effect.

The SL controller is using the directory structure to detect the J2EE     

engine

Can you please rename the directoryj2ee dir under  /usr/sap/SID/DVEBMGSXX/j2ee       

something else and start the upgrade all over again

3)If you want Delete JAVA Stack in system with ABAP+JAVA please follow the below thread.

If there is no Java stack present then from where will SUM identify the Java stack ?

Dear Fabio,

Now SAP Not recommanded for Dual Stack for SAP BW.

SAP NetWeaver Business Warehouse comes for Separate Stacks.

If you want both stack in same server machine you can install separatly with Same SID, Integration of ABAP and JAVA stack take care of Sapinst automatically and Database also Connected MCOD option.

If you want two maintain ABAP & JAVA separate machine also fine. Integration do by manually.

If any one already have dual stack for BW 7.0...first they need to split the stacks then upgrade each stack separatly.

Thanks & Regards,
