Adding Java Stack to Upgraded ERP6.0 ABAP Stack

[Former Member]

Hi All,

I have upgraded SAP R/3 4.7 to ERP 6.0 SR3 with MSSQL 2005 on Windows 2003 Enterprise Edition.

Right now my upgraded system is having only ABAP stack and I want to add Java Stack to It.

I want to know is there any specific procedure to do this task, or it can be done just as normal installation by running Sapinst and selecting the Java stack option when it shows the component to be installed and then making sure the correct instance number is avaliable (01 in my case as 00 is for ABAP stack) and making sure for the ports that will be assigned to Java Stack.

Please clear me if I am wrong and there is some separate procedure by SAP.

Hi Vinay,

You are right. You can perform the Java Add-In installation with SAPinst (installation services available in SAPinst under: "Additional Lifecycle Tasks --> Java Add-In for ABAP --> <Database> --> <Central System / Distributed System / High Availability System>").

P.S: But for ERP 6.0 EHP4, you cannot install Java as Add-in to existing ABAP system (check SAP note 855534)

Thanks

That is Java add in for Abap ..right ??

but when we do installation normally there we go to ..Sap ERP 6.0 Support release 3> Database>Central system and then in the Software Units step we have to choose which software unit we want to install like AS Abap , AS Java , Bi java ,DI ,

etc...

So my question here is If I choose AS JAVA option here then what will it install ??

Secondly is there any difference between Java Add-In and AS Java ??

When we choose the option AS ABAP and AS JAVA both then after installation under mmc we can see seperate instances for both 00 for Abap and 01 for Java in many cases(if we keep instance no. default)

No there is no difference.

In case of ABAP+JAva you will see one for D* and other for SCS. not separate for ABAP and Java.

Yes. For EHP1, check SAP Note 1169801 - Inst.NetWeaver 7.0 EHP1/Business Suite 7 - UNIX
