RMAN-07518: Reason: Foreign database file DBID

Wed, 2014-06-04 05:06
While cloning a database to another system through RMAN in an 11.2 database on a Linux system, there was a need to catalog the backups after putting the destination instance in mount status, before the restore/recover process could be started.

During the phase of cataloging, got the following error:

RMAN-07518: Reason: Foreign database file DBID

Upon checking, it was learned that there was a mismatch of database incarnation at the source and the destination databases.


In order to resolve this error, you need to make sure that the incarnation number of both source and destination databases is same. So check what's the Current Incarnation Number at the source database, and then reset the incarnation of destination to the same.

For example if the incarnation number at the source is 3, you can reset the incarnation of destination in RMAN by:

RMAN> reset database to incarnation 3;

Now the cataloging the backup files worked fine.

From Las Vegas to Ottawa

Wed, 2014-05-28 21:16
After a very engaging session at Collaborate14 in sunny Las Vegas amidst the desert of Nevada, I just arrived in not-so-bitterly cold Ottawa, the capital of Canada. Looking forward meeting with various Pythian colleagues and hanging out with the friends I cherish most.

My Exadata IORM session went well. Lots of follow back discussion plus questions are still pouring in. I promise I will answer them as soon as I return to Australia after couple of weeks. That reminds me of my flight from one corner of the globe to the other, but well I need to learn as how to sleep like a baby during flights. Any ideas?

Ottawa reminds me of Australian capital Canberra. It's quite a change after neon-city Vegas. Where Vegas was bathing in lights, simmering with shows, bubbling with bars, swarming with party-goers, and rattling with Casinos; Ottawa is laid-back, quiet, peaceful, and small. Restaurants and cafes look cool. Ottawa River is mostly still frozen and mounds of snow are evident along the road sides with leafless trees.

But spring is here, and things look all set to rock.
