Question about Log Shipping: Secondary non-writable?

Hi, i think i'm just getting confused with all the reading. I have 2
servers, A is live and B is doing nothing. I want to create some kind
of warm standby so I looked at replication and log shipping. Repl
seems to be kinda messy so i think i will go with log shipping.
Database is around 2gigs and i can live with an interval of around
1/hr log ship.
Now my question is i read somewhere it says the databse on the second
server is read only...non writable? So what happens if i need to
failover and make the secondary server live? Is it then only readable
but unwritable? What good is that? Any ideas?>...or i just got it
wrong?The secondary is unwriteable as long as you are shipping logs. Once you
take it live, it becomes he 'real' database server and starts servicing
requests. Note that I am answering your questions on a conceptual level, if
you want the technical details of HOW that happens, that is for a follow-up
question.

to make a secondary database primary... including how to get the logins to
match... Search for Log shipping ...
