Re: Using GHOSt with ASM disks - Cloning

Thanks hpuxrac

May consider 11G.

Very good feedback much appreciated.
Hint about posting noted.

Other possible solution I have come up with is to remove disks from RAID controller 1 by 1 and let RAID array rebuild in bios raid screen. Putting removed disks into Dr server assuming both servers identical hardware.

Probably GHOST will continue to work but you will need to shutdown both the database and the asm instance if you want to avoid all potential problems before making the copy.

If you are running 11g you won't need either a tape or disk based rman backup ( rman can clone over network without having an rman backup established ).

Oracle's recommended direction is certainly to use rman in general. If you wanted to ( and I don't recommend this at all ) you could use GHOST and then get periodically a set of archive logs until you establish a new GHOST baseline.

Lots of options based on the respective skill sets available. But rman is the strategic and long term direction to look at. Received on Fri Apr 11 2008 - 10:47:50 CDT
