Hello
This is oracle based NW7.0 installation which is ABAP+JAVA . I would like to use the oracle specific procedure with tracing the control file and then restoring the backup of the PRD system to the QAS. This will work for the ABAP stack, but how about the JAVA stack?. The PRD has higher java stack 21 while the QAS is at 18.
How shall the JAva part refresh be done?
You can use Backup of ABAP and export of JAVA stack for the refresh

Hello
1. Yes Yes it is not QAS but PRD ...typo
make PRD java export and import will be done with sapinst
that means use oracle backup restore for ABAP and export/import for JAVA
You can start sapinst with system copy using backup restore method
3. there is cluster data for each java system like QAS which can be after system refresh
Hi,
If you are restoring dual stack system then you have to export and import Java part as well which is not possible by back up and restore.
Best approach is homogeneous system copy ...
Thanks

This should be done following the homogenous system copy guide, any other procedure can guarantee a large headache.

Hello
The steps can be
SAPINST with backup restore
Source :PRD
Dest:QAS
1. export the JAVA only part from QAS system . Make the control file structure and just keep it ready
2. do all pre system copy steps on QAS
3.start sapinst on QAS and select system copy with oracle backup restore method
at the time when it stops ,do the copy manually frpm PRD to QAS of required files and keep the control file ready ( do not do anything to create control file or open database )
4. continue with the installation and the database will be open also it will ask for migration export for JAVA and give the export path what u have in step1
5. Do the post steps on QAS
SAPINST with export import
Though above method is bit easy but I will prefer to go with SAP export and import method as it is easy and just start and it will keep running . Only headche with this is JAVA configuration has to be saved on QAS before hand and then in post processing there can be changes releted to QAS SID and hostname . But i do not remember on how many places and the steps
Success !!!
1. - you mean export the PRD Java stack, i guess?
3. if i don't do anything with the control file i am guessing the when sapinst opens the db it will still be under the PRD SID right?
Why do i have to save the QAS java configration if i want to refresh it completely from PRD?
sorry if the question is stupid, but i am not experienced with the Java stack part at all
