Dear all, I'm a "newbie" on SQL2005 mirroring and I need some help. I'm going to set up a db mirroring with high availability, I mean with principal-mirror-witness scenario. I know that if the principal goes down, the mirror automatically take its place. But at this point, is the DB in read only mode ?? Or is any WRITE/modification allowed ?? Thanks in advance! Luca |

Good question. The mirror automatically takes over all the functionality of the principal, including read-write transaction processing during a failure event. Everything keeps running. -- Geoff N.
