Mirror Disconnected - Database Upgraded

Hi

While a database upgrade schema changes were being made the Mirror became disconnected will this recover itself when it reconnects or will it be the case that we will have to copy the db files to the Mirror and set it up from scratch.

It was set up as a synchronise mirror

Hi Jasonmr,

What sort fo changes were you running.

What errors are logged in the error log of the mirror and principal?

regards

What kind of DB mirror mode you are running?

If in high availability mode then the committed transactions will be available on Mirror provided the redo queue has been applied there, if not until unless the transaction is written to disk and tranasfered to mirror it will not be available on other server.
