I need to recover a datafile. I took the datafile offline, restored a backup of the datafile, and started to recover the file. I issued the following command:
recover datafile 'F:\ORACLE\ORADATA\PSSYS1\PTTBL.DBF'
and got the following message:
ORA-00283: recovery session canceled due to errors
ORA-01190: controlfile or data file 90 is from before the last RESETLOGS
ORA-01110: data file 90: 'F:\ORACLE\ORADATA\PSSYS1\PTTBL.DBF'
I am new at this so any help would be greatly appreciated.
