    Datafile recovery -- Urgent

    The status of the datafile is RECOVER, I have flash back recovery enable.

    In my 1.6 yrs carear this is the first time, I never recover the datafile, there are three datafiles for the tablespace. But all of the important objects of the schema is stored in that tablespace

    Need guidance to recover.

    The database is in Archive Log Mode, only one Datafile is in Recovery mode, the last backup is of 21-Jul-2006. I have archive logs after the last backup. The backup is taken through RMAN to disk

    The version of Database is 10gr2.

    Is it possible to recover only specific datafile, without effecting the other?

    1. identify the FILE_ID of the lost datafile
    2. Start rman
    3. RMAN> restore datafile file_id;
    4. RMAN> recover datafile file_id;

    If should recover the datafile if all the archive logs are available.

    dear pando do u mean to recover the entire tablespace or a specifc datafile, after making the tablespace offline?

    HTML Code:
    According to Thomasps
    
    1. identify the FILE_ID of the lost datafile
    2. Start rman 
    3. RMAN> restore datafile file_id;
    4. RMAN> recover datafile file_id;
