I have lots of problem with my backups of Oracle DB. Every 2 hour a online backup is run.
If I'm lucky it's successfull but often I get a Corba error.

No firewalls is activated and I can access port 5633 from my Orace DB server to Media server. I do not use IPv6.

When I check the Debug logs I can see why I get this error:

CBsaHandlerBE::vxbsaQueryObject() - Source device for the object search:Oracle-Win::\\PROCDB_NEW\VOO

[icorba] - : 3) Media server machine can be pinged from this agent machine
[icorba] - if it can not be pinged, add entry of media server in etc/hosts file.

The IP for BSA_SERVICE_HOST is completely wrong.
On every Oracle settings in the agent I have used the IP address to my Media server. How can this IP be used then?

Could it be the Authentication List for Oracle servers?
Acordning to the manual:

"You must add the Oracle fully qualified domain name and the logon account name
to the media server’s list of Oracle servers and authentication credentials."

But I use a special backup IP on my Oracle servers, If I enter FQDN I could get wrong IP due to wrong DNS lookup.

I have no problem with this when I used BE 12.5. All problem occurred after my upgrade to 2010 R2 SP1.

Is there a way to bind the backup IP to the Windows Agent?
