hi john,
well we have a problem as the error appeared in alert log on 13 Jun 2012 and it has been reported now and from 13 jun till now NO Physical backup are taken which is a mess, but the logical backup are ok. we have created tablespaces quaterly i.e (Jan to Marc) is M12 and so on, so we have datafile offline at J12 (Apr-Jun) tablespace and after working out it reveals that this datfile size is 2 gb and it was created on 13 jun and got corrupted on the same date, so may be it dont have data but we need to recover it so how can i recover this file and why the export of this quarter is successful as there is one datafile offline of J12 tablespace.

Kindly guide



Regards

Presumably you are in archivelog mode? Then no problem:

http://docs.oracle.com/cd/E11882_01/backup.112/e10642/osadvsce.htm#i1006226

restore and recover when no backup is available is a standard exercise in any decent Oracle admin class.

No, We don;t have any archive log before file corruption, and if a datafile is corrupt so its logical backup of that tablespace should fail, but here the logical backup is successful, what you say about this

Why should it fail? Think about what it is doing, and all will become clear.

The real question is why you are not running in archivelog mode. If the database is considered important enough to need RAC, then it is surprising that you are happy to lose all the data entered between backups.

I see.
Well, there is no way to recover that datafile. You only option is to drop the tablespace, including contents and datafiles. You say the logical backup went through OK, so presumably the file went bad before it had been used. In that case you should be able to create a new tablespace and import the logical backup.
You were lucky! But not as lucky as your DBA is, to still have a job.
