Undo tbs corruption ora-00376,ora-01110

Hi all,

I am getting these errors in my alert log:

ora-00376: file 2 cannot be read at this time
ora-01110: datafile 2: 'f:/undotbs1.dbf'

when i checked dba_rollback_segs i found all the segments needed recovery apart from 2 which were offline. system was online. Can i just recover the particular datafile for the UNDO tbs? or is there more to this?

Urgent help needed

Thanks in advance,

Recover should be fine.
RECOVER TABLESPACE (if successful) should solve the problem.
If not successfull, then you are in deep problems

Regards
Boris
