Home -> Community -> Mailing Lists -> Oracle-L -> RE: Recover Primary DB from Standby DB
Errr...what's the point in having a standby database then? If you have a media failure then you fail over to your standby database, and your up. Once the standby database comes up then you will have to rebuild the old primary database from the old standby anyway, since you now have all these new transactions hitting the old standby server.
Thoughts?

The first thing that comes to mind is the datafile header.
I'm too lazy too look it up myself ( ;) ), but you might want to consider header data that would cause the primary db to reject the file.

Am I an Idiot?
I've maintained a Managed Standby database (8.1.6 under Win2k) for a year now. We've now moved to new servers (8.1.7.2.5 under Win2k) and will again have both Primary (Production) and Managed Standby databases.
In planning a new backup stragegy, it occurs to me (why not ever before?) that I should be able to use the datafiles of my Standby DB (along with the Primary's archived and online redo logs) to recover my Primary DB in the event of media failure.
In the event of a drive failure on the Primary server, shouldn't I be able to shutdown the Standby DB and copy it's relevant datafiles to the Primary, then use the Primary's archived and online redo logs to recover those datafiles to the point of drive failure?
It makes sense to me, but nowhere in the docs have I found mention that
this
is an appropriate action. Am I missing something?
