How to bring Second SQL Log Ship Server Online

Hi -
I have log shipping configured and working.(SQL 2005 SP2). Both
shared directories on the Primary and Secondary servers are full of
logs and the status of the Secondary database is always showing
(Restoring...). Now the Primary server just took a hard dump. Could
someone tell me how to bring the Secondary server on line so that the
application can access it?
Thanks

100 logs or so, I'm doing the default every 15 min. Do I need to
restore all of them? Or what if I ship every 2 hours, does that mean
at anytime I can lose the last 2 hours when I fail over?
RSC|||You should restore your lastest log with RECOVERY to bring your Secondary
database online in case of a failure that may happen on your Primary
database.
You did not mention what the time period is to restore the logs that are
brought to your secondary server from the primary?
For example:
Step1= Backup Logs on the Primary Server
Step2= Copy Log backups to the Secondary Server from the Primary Server
Step3= Restore copied Logs on the Seconfary Server
There are time intervals between these jobs.
For example: if you perform step1 every 15 min. step2 every 15 min and
perform the step3 every 30 min. (Which is 15 min. for all steps by default)
Then:
13:00 = step1 + step2 + step3
13.15 = step1 + step2
13.30 = step1 + step2 + step3
13.45 = step1 + step2
13.55 = Primary Failed
As the lastest copied transaction log arrived to the Secondary server at
13.45, you'll have it on your Secondary server (if you designated a folder
as a destination copy folder on Secondary server) And you'll just restore
that lastest transaction log because according to this scenario older ones
are already restored (at last at l3.30 in this example)
If you have a chance to take tail log backup from the primary server then
you'll go to your primary server and take tail log backup of your database
and you'll restore it WITH RECOVERY on your Secondary database. If you don't
have this chance then you'll restore your log backup which was copied to
your secondary server at 13.45 using WITH RECOVERY to bring your secondary
database online.
Again, you should apply all availabled and not restored-before transactions
WITH NORECOVERY until the lastest one. When you come to the lastest log
which could be the lastest copied log from the Primary database or Tail Log
from the Primary database, you'll restore it using WITH RECOVERY to bring
your Secondary database online.

I have step1 and step2 automated, but I see now that I should automate
step3 on the secondary server, then do a log restore RECOVERY at when
the Primary goes off line. Last but not least; how easy is it to get
the Primary back on line once it is repaired, say after a power supply
failure? I'm thinking, backup the database and restore it on the
Primary, then re-setup the log shipping routine as it was before the
Secondary was recovered. Now I'm back to the begining.
RSC|||After such a failure, your database could be corrupted or damaged. It
probably would be the best to restore the most up to date version of that
database's backup. In your situation the most up to date backup is your
ex-secondary database. And yes, after this you can resetup Log Shipping and
live happily after.
Log shipping is Warm Standby HA system so you must do this stuff manually...

application is Websense reporting so any lost data during the failover
or re-setup is not much of a loss anyway.
Thanks Again!
