ERROR:
  ORA-600 [3668] [a] [b] [c] [d] [e]

VERSIONS:
  versions 7.0 to 9.2

DESCRIPTION:

  This is the FIRST time an attempt has been made to start an instance 
  after a CREATE CONTROLFILE command has been issued.

  At least one data file needs MEDIA RECOVERY.

  The error has been externalised in Oracle 9.2.x as :

      ORA-1113: file  needs media recovery.

ARGUMENTS:
   Arg [a]  File number needing media recovery
   Arg [b]  Control file status 
   Arg [c]  Control file checkpoint count
   Arg [d]  File header checkpoint count
   Arg [e]  File header status
 
FUNCTIONALITY:
  CACHE RECOVERY COMPONENT
 
IMPACT:
  INSTANCE FAILURE - Usually unable to start the instance when
                     receiving this error.
 
SUGGESTIONS:        

  This should only ever be signalled if a CREATE CONTROLFILE has just been 
  performed and one or more files need media recovery.

  In this case it is best to:

  o  recreate the controlfile again.

        Prior to doing this, check that the create controlfile statement
        is accurate in all respects.

        For example, check that it contains the correct number of 
        datafiles for each tablespace and that these files exist.

        Check that it contains the correct number of redo log groups.

  o  Perform the appropriate media recovery

         The type of recovery to be performed depends on the circumstances. 

         Doing a complete media recovery :

             RECOVER DATABASE (if create controlfile was NORESETLOGS)
             ALTER DATABASE OPEN;

         Doing an incomplete recovery (for example time based, change based
         or until CANCEL) :

             RECOVER DATABASE USING BACKUP CONTROLFILE (if using RESETLOGS)
             ALTER DATABASE OPEN RESETLOGS;

             You may need to supply the names of the ONLINE logs to complete 
             the 'BACKUP CONTROLFILE' recovery.
