ORA-00214 Tips

Oracle Tips by Burleson Consulting

Problem:  Due to electric failure my database server went down. When I restarted it returned an ORA-00214 as shown below:

SQL> startup

ORACLE instance started.
Total System Global Area 83605532 bytes
Fixed Size 75804 bytes
Variable Size 57016320 bytes
Database Buffers 26435584 bytes
Redo Buffers 77824 bytes

ORA-00214: controlfile 'D:\ORACLE\ORADATA\DATA\CONTROL01.CTL' version 11541 inconsistent with file 'D:\ORACLE\ORADATA\DATA\CONTROL03.CTL' version 11538

Can someone help me with the solution to this ORA-00214?

Solution:  The docs  note this on the ORA-00214 error: 

ORA-00214: control file "string" version string inconsistent with file "string" version string.

Cause: An inconsistent set of control files, datafiles/logfiles, and redo files was used.

Action: Use a consistent set of control files, datafiles/logfiles, and redo log files. That is, all the files must be for the same database and from the same time period.

Typical ways to get an ORA-00214 include forgetting to replace ALL OF the current control files in all locations specified in the init.ora control_files parameter.  Remember, all of the control files, in all locations, must match exactly.

All copies of the control file must have the same internal sequence number for
Oracle to start up the database or shut it down in normal or immediate mode.

If the database is running and the checkpoint in the file header could not be
advanced the datafile will be taken offline.

Typical scenarios in which you may receive an ORA-00214 include:

  • You have restored the control file from backup, but forgot to copy it onto all of the mirrored copies of the control file as listed in the "CONTROL_FILES" parameter in the init.ora file for this instance
  • You have moved one or more copies of the control file to a different location while the database was up and running.
  • You accidentally overwrote one of the copies of the control file with an old copy.
  • The database or the system crashed while the mirrored copies of the control file were being updated, causing them to be out of sync.
  • You are restoring a database backup that was improperly taken
    with the database up and running ("fuzzy" backup).
