Notify Operator Tasks are independent of a database context.
Furthermore, the text that's entered into the Properties dialog box gets passed into a statement resembling the following (obtained by clicking the View T-SQL
button):
EXECUTE msdb.dbo.sp_notify_operator @name=N'My Operator',
@subject=N'Subject',@body=N'Message Body'
So what do you do?
Getting the server context is easily solved by switching to an Execute T-SQL Statement Task where you can put whatever SQL you want in there.
That doesn't solve the database name issue, though, because you'll get back either master
or msdb
and not any particular user database. I don't believe it's possible using Maintenance Plans to get the database name for what you're trying to do. The Back Up Database Task is entirely self-contained.
What you would need to do is use SSIS proper and put a Back Up Database Task and Notify Operator Task within a loop container, where the flow would be executed for each database individually.
Or, you could take a completely different approach and use a script-based backup solution and customize it to suit your exact needs.
