Cause: The control file change sequence number in the log file is greater than the number in the control file. This implies that the wrong control file is being used. Note that repeatedly causing this error can make it stop happening without correcting the real problem. Every attempt to open the database will advance the control file change sequence number until it is great enough. See the solution below.

Error solution: Use the current control file or do backup control file recovery to make the control file current. Be sure to follow all restrictions on doing a backup control file recovery.
