Oracle backups fail after moving from v8.2 to v9.1
I recently moved some of my oracle backups from a v8.2 NetWorker server to a v9.1.1. Since then the backups fail.
The oracle databases are running in a clustered environment. There are two physical servers where the NetWorker client and NMDA is installed (node A and node B). In the NetWorker config are three client resources. Each physical server has one for the filesystem backup (node A and node B). Then there is a third node (node C) which has the RMAN- and NMDA-path specified. The DNS entry for node C points to the active physical node.
After running a oracle backup, I get the message:
<node A>:"No save sets can be found in the NetWorker media database for this backup."
RMAN does not report any failures and completes the backup successfully.
Filesystem backups of node A and B are running fine too.
I deleted the node A and node B resources and inserted them in the alias field of node C. Then the backups completes fine. After removing the aliases again and creating the client resources for node A and node B, the backups fail again with the message above.
Then I moved back to v8.2 and the backups did finish correctly again. Backing up to the v9.1.1 NetWorker server with the v8.2 NetWorker client also fails with the same message.
