RMAN-06187: controlfile copy string not found or out of sync with catalog
Cause: The indicated file is not found, or is found but is not the same file that the recovery catalog thinks it is. It is likely that some operation outside of Recovery Manager has altered the file, or that Recovery Manager has not resynchronized with the target database.
