Database Mirroring - Multiple databases

I know database mirroirng is on the database level but is it possible to fail
all the databses in the server if one databses fails.
If I want to mirror db1 and db2 serverA to db1 and db2 in serverb. If db1 in
servera fails I want db2 in servera fails therefore both database will
rollover to serverb.No, first off database mirroring is not scalable to a large number of
databases. Secondly what will happen is each mirroring pair will failover on
its own schedule. All of them should fail over within several seconds
though.

database mirroring

I am new user of SQl and preparing the exam database mirroring....can you tell me how i start the mirroirng ..what is my first tep..and is there only one instance

The first step is, you need at least 2 instances for mirroring, otherwise it's meaningless.

I suggest you open up SQL Server 2005 Books Online and read every topic on mirroring thoroughly.

Why are you taking an exam in it if you don't know anything about it? Seems a bit pointless to me, maybe I'm just jaded and cynical.
