Hello,

Safety = FULL. No witness.
Principal goes down, and there's a long redo queue in mirror and will take long time to be up.
Suppose I am not worried about those logs but I just need to bring the mirror server up.
Is there any way to cancel those redo logs in mirror ? Data loss is acceptable.


Thanks,
San.

No, it's the same as crash recovery when starting up a DB. Without there are logged changes that do not reflect in the data file, ie the database would be inconsistent without them

.. So ultimately I need to wait till it recovers. And time left to recover will be available in Mirror error log is it ?
By the way, a FORCE failover won't help here as well ?

Thanks Gila.

Should be.

Forcing a failover won't help, because this is not the failover process, it's the bringing of the DB online after the failover.

Do I understand correctly, the same delay will happen when failing over when using clustering or log shipping?
