Error ORA-01167 2c4yn
ORA-01167: two files are the same file/group number or the same file
Cause: There is an overlap of file numbers in the files specified on the command line or the same file is specified twice. If they are not the exact same file then one is likely to be a backup of the other. If they are two of the same log they must be specified together in a group file spec. This message will also appear if the same control file appears more than once in the control_files parameter in the init.ora file. If this happens, check for additional error messages.
Error ORA-01169 3q45a
ORA-01169: DATAFILE number 1 not found. Must be present
Error ORA-01171 11w2p
ORA-01171: datafile string going offline due to error advancing checkpoint
Cause: The checkpoint in the file header could not be advanced. See accompanying errors for the reason. The datafile will be taken offline the same as for a write error of a data block.
Action: See accompanying errors for details. Restore access to the file, do media recovery, and bring it back online.
Error ORA-01177 u34j
ORA-01177: data file does not match dictionary - probably old incarnation
Cause: When comparing the control file with the data dictionary after a CREATE CONTROLFILE or OPEN RESETLOGS, it was noted that this datafile was inconsistent with the dictionary. Most likely the file is a backup of a file that was dropped from the database, and the same file number was reused for a new file. It may also be that an incomplete recovery stopped at a time when this file number was used for another datafile.
Action: Do a CREATE CONTROLFILE with the correct file or none at all.
