NW04 system copy : we only need the abap stack

[Farid]

Hello,

We have a BW 3.5 Production environnement :

• Netweaver 04

• Oracle 9.2

• ABAP + JAVA stack have been initially installed on the same server but the java instance parameters have been since deactivated. The Java stack has never been used.

Now, we're planning to install the same BW 3.5 QAS environnement (only the abap stack), configure it, and afterwards perform a typical homogeneous system copy (backup/restore) from the production environnement.

Since we don't need at all the java part, do you think that could work ? Is there any risk of inconsistency ?

Or do we have to install double a stack QAS enviroonement and then perform the system copy based on sapinst

?

Thank you in advance for your help.

Regards.

If you no longer need the Java stack, run SAPINST an uninstall it. Make sure you have a good DB and file level backup before starting!

You will have to perform following steps

1. Export the CI system on Source system

2. Clone the source Database to Target database. We have used IBM's Flash copy tool to accomplish that.

3. On target install SCS , restore the DB and then import CI.

We also have dual stack in ECC Production environment and we don't use JAVA as much.

If you have any more questions, please let me know.

Thanks

Hi,

For system copy you can not perform seperately, So you have to perform the complete system copy and the uninstall your java stack.
