Accidentally overwrote an index file with a cold backup file!!!

 

  

Hi,
Need your help!!... as I was asked to do a copy of a tape, I accidentally overwrote an index file as I was doing the restore to disk (/opt/oracle/oradata/cidesi/xdb01.dbf) , and of course the database is up, so far there has not been any complain, but I am afraid as soon as I do a shutdown/startup something on the databse something might go wrong (a cold back is done daily), I did an export on the main schemas before doing the failed restore..... could someone advice on what to do before this gets serious??... any suggestion is appreciated.


Many Thanks in Advance,
-Adriana.
