ORA-01176: data dictionary has more than the string files allowed by the controlfie
Cause: After a CREATE CONTROLFILE, the data dictionary was found to have more datafiles than that supported by the control file.
Action: Recreate the control file with a larger MAXDATAFILES.
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.
