Downgrade Maxdb - Please help

Posted on Nov 09, 2011 at 07:56 AM 51 Views

Hi all please shed some light on this issue

I am doing SAP sys copy using Backup restore.

The IM DVD i am using to run sapinst worked 100 % with version 7.6.

I recently went up to version 7.8 and now sapinst is unable to create the DB instance in the sys copy procedure.

In the sapinst i specify rdbms Version 7.6 but because my database install is allredy on 7.8 it tries to create the instance on 7.8 and fails.

Is there a way to uninstall version 7.8 run sapinst and then do the upgrade just before the restore

As per note 1469675 this is how i am supposed to do it, but the problem is that i dont get to the stage when i can upgrade ...

It tries to create the instance based on version 7.8 and fails.

Thank you for any replies

    What installation master DVD are you using? The way describe in the note should work with the latest DVDs for you release.

      I understand your frustration, I was dealing with likewise issues some time ago. Since MaxDB 7.8 changed the internal software structure to enable isolated installations and sapinst doesn't know about this, you have problems with those "old versions" of DVDs.

      You can try the following:

      - install a new database client using the maxdb-as* package using

      ./SDBINST
-profile "Runtime For SAP AS"
-i CL_<SID>
-private_datapath /sapdb/clients/<SID>/data
-path /sapdb/clients/<SID>

      - start sapinst, select system copy and step one or two dialogs further

      - stop sapinst

      - put the sapdb.inf from the note to the installation directory

      - restart sapinst

      - "continue old installation"
