RMAN-05501: aborting duplication of target database
RMAN-06136: ORACLE error from auxiliary database: ORA-01276: Cannot add file /oracle/oradata/teststby/o1_mf_19_9hcqsyb9_.log.  File has an Oracle Managed Files file name.

Reason:

OMF parameter set in the database, hence the file name cannot be specified while adding log file

Solution:

Remove following parameters if they are set in parameter file and rerun rman duplicate script

db_create_file_dest
db_create_online_log_dest_1
db_create_online_log_dest_2
db_recovery_file_dest
