Mirror of master, msdb, tempdb, or model databases.

Hi Guys,

Since,You cannot mirror the master, msdb, tempdb, or model databases.What will happen if i create new login,change existing security profile and new jobs,change of existing job on princicpal db. how these will be mirrored to other server and in case failover, how it will treat.

Thaks

Mirroring works at the database level only. dts/ssis packages, jobs etc are not mirrored. Database users are mirrored but not their corresponding SQL Server login.

You need to keep a copy of dts/ssis packages, jobs etc on the mirror server and whatever changes you make to them on the principal server, you will also have to make on the mirror server if you want to keep the servers exactly in sync.

hope this helps
