I have 2 servers, one for DB and the other for APP (Citrix), I am using oracle 9i over windows 2000 server.
Guess that I wake up a day morning and I found my servers is fully damaged, or disappeared cause for natural disaster or burning ...
what the procedure I should did before, so I can run-up a new server????
what is the right backup plan for this, what things I have to back them up?
and how I can rebuild the server and the DB and windows ????
They are manny options in Oracle. There's DataGuard, they are Stream (log shipping), there's Standby, there is RAC (allthough RAC is generally for in-house location).
If you take backups with RMAN, and you want to build your server from SCRATCH, assuming you lost the whole server, you will need to first restore your database software (the executables), and then restore the RMAN backup.
It will all depend on how complex (or simple) is your infrastructure and how good is your disaster planing methodoly, that's what will dictate how much you would spend in recover.
