Operating conditions after mirroring.

Are there any restrictions in the restored database after database mirroring?

I mean, Is it full mirror of my primary database?

What I want to do:

If my machine A(with primary database) will down I will redirect my clients to a real-time copied database - mirror server. I don't want to create cluster, but I want to use database mirroring function in ms sql 2005.

Can I use DB Mirroring to solve my problem?

p.s. sorry for my english

Yes that is exactly what mirroring is for. The mirror database is an exact copy of the principal.
