Sanjay,
After fixing hardware on Production server, I think you can create Physical Standby Database and later switch it as Primary.
Can anyone comment on this......what would you do if you get into such situation?
Thanks
Muqthar

Hi Sanjay
Your question was not clear. So, I am assuming you are trying to
convert the former primary to current standby, so that you can switch
over later. If this assumption is correct, then the answer 'it depends'.
If you have switched over to the standby database gracefully, then you
can restore just those four tablespaces and recover the former primary
and convert it to standby. Basic premise is that 1) all the redo
generated from the primary was propagated to the standby db before the
switch 2) Former primary did not generate any redo by itself after the
switch and so former primary is essentially a backup of the current
primary.
If this premise holds good, then you can restore those 4
tablespaces alone and recover them..
But, If you have kept the primary open after the switch, thereby generating redo or if you have used resetlogs to open the secondary (for some reason), then you must use the current primary (or its backup) to rebuild the standby database.
Let me know if I misunderstood your question..
HTH
