Oracle terminated due to control file locked (Legacy KB ID CNC TS17012 )

This is also a common problem when using backup software. The backup utility locks the datafile, controlfile or logfile. When Oracle attempts to write to the file, the lock prevents it and the database crashes. Backup software should be configured so it does not lock open files. In this case, contact the third party vendor for information on how to not lock open files.
