Answer / guest

Cause: A copyDataFileCopy, restoreDataFileTo or
proxyRestoreDataFile function specified a file number but no
output file name, indicating that the output filename should
be taken from the controlfile. However, the controlfile
entry for this file indicates that it was created for a file
that was present in the data dictionary but not named during
the last CREATE CONTROLFILE statement, so the name in the
controlfile cannot be used for restoration.

Action: Either specify an output filename or issue a SQL
RENAME command to enter a valid name for this file in the
controlfile.
