Is it possible to failover a single or a selected number of databases
onto a standby server? We're currently log shipping about 12 databases
to a standby and I was wondering if it was possible to randomly
failover onto selected dbs.
My understanding of log shipping is that when the primary server goes
down, the standby takes over. But, does that mean that all of the db's
on the standby server now become the primary? Or, can failover occur on
selected dbs?
The reason I ask is because if one db on the primary, for example, was
to go down, I'd like to be able to bring the particular db on the
standby server online while I fix or restore what's on the primary
server. Can it be done individually or is it an all or nothing
scenario?
Your personal advice or links is greatly appreciated.
Thanks,

As far as I know there is no automatic failover with log shipping, but
you would have to failover clients manually.
If you are using database mirroring, failover can be automatic, and I
assume that this is per database, but I don't know.

I am setting up a HA solution which incorporates both the DB Mirroring and Log Shipping with SQL Server 2005.
However I am running into a bit of a snag in configuring the mirror as the primary/inactive log shipped database.
From what I can tell one should be able to configure the mirror DB separately as a logged shipped database and when a mirror failover event happens the Log Shipping jobs should be able to come from whichever is the...

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
