Hello,

I have a 8.1.6.2 database which is about 8 Go in size. I have to restore a 1,5 Go tablespace (which is 3 physical files of 500Mo) to recover (by an export) the data of a table accidently overwritten and just this table. The backup is done every day at night. It is a cold backup of the database files (database closed).
The problems are : i have only 1 Go of free space on my Unix AIX system, it is a datawarehouse base and
i could not stop the base. I can put offline the tablespace for a limited time.

Can i do ? :

1 -put offline the original tablespace
2 -backup it on a tape, delete it
3 -restore the old one TBS
4 -put online in restricted mode the restored TBS
5 -do the export of my table
6 - put offline the TBS
7 - delete it
8 - restore the original TBS from tape

Thanks for any advices
Best Regards
Philippe
