"file %s is MISSING"
*Cause: A COPYDATAFILECOPY, RESTOREDATAFILETO or PROXYRESTOREDATAFILE
function specified a file number but no output file name,
indicating that the output file name should be taken from
the control file. However, the control file 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 control file cannot
be used for restoration.
*Action: Either specify an output file name or issue a SQL RENAME command
to enter a valid name for this file in the control file.
