MaxDB does not start after backup/restore: duplicate_invkey

Hi

I use MaxDB 7.8.02.35 on SLES 11.2 (Kernel 3.0) OLTP & DBStudio 7.9.08.12

I wanted to resize (shrink) & relocate the logfiles. As I found out this is only possible with a backup/restore with initialization (Note 869267 - FAQ: SAP MaxDB log area  ). Before backup the DB had Redo-Management deactivated for performance-reasons.

The Backup went fine as did the Recovery with initialization, all done through DBStudio.

But if I try to start the DB with db_online I get the following error:

-24988,ERR_SQL: SQL error

250,Duplicate secondary key

3,Database state: OFFLINE

Internal errorcode, Error code 3320 "duplicate_invkey"

db_admin works fine.

I tried the approach from Lars mentioned in  http://scn.sap.com/thread/1803992  but it didn't help.

Also, as I didn't change any parameters during initialization, usernames and passwords should be the same as before, as is the DBSID and everything else.

Any ideas?

Best regards

Michael
