It may be the case that a backup or copy of this file exists but does not satisfy the criteria specified in the user's restore operands. Action: None - this is an informational message. See message 6026 for further details. RMAN-05501: aborting duplication of target database RMAN-03015: error occurred in stored script Memory Script RMAN-06026: some targets not found - aborting restore RMAN-06024: no backup or copy of the control file found to restore
This error is related with the SCN of the highest backed up archived redolog and will try to find a backup of the controlfile.
You can resolve this by making another archivelog backup of the target database.
RMAN> backup archivelog all;
and than restart the duplicate afterwards, then the database duplicated successfully.
Or you can solve this error by using catalog backuppiece command as follows.
RMAN> catalog backuppiece '/rman/backup/c-4673639742-20200130-01.ctl'; cataloged backup piece backup piece handle=/rman/backup/c-4673639742-20200130-01.ctl RECID=37 STAMP=897176040
