based on my understanding from http://download.oracle.com/docs/cd/B19306_01/backup.102/b14191/rcmdupdb.htm#sthref908

Quote:

As part of the duplicating operation, RMAN automates the following steps:

Creates a control file for the duplicate database

Restores the target datafiles to the duplicate database and performs incomplete recovery by using all available incremental backups and archived redo logs

Shuts down and starts the auxiliary instance (refer to "Task 4: Start the Auxiliary Instance" for issues relating to client-side versus server-side initialization parameter files)

Opens the duplicate database with the RESETLOGS option after incomplete recovery to create the online redo logs (except when running DUPLICATE ... FOR STANDBY, in which case RMAN does not open the database)




when duplicating for standby database it does not create online redo logs. please correct me if I'm wrong on duplicating a standby database does not creates online redo logs.

how should I add the online and standby redo logs. If I transfer the redo logs from primary to standby, it always encountered the the following error

You have to create standby redo only not online log file. Did you try this

ALTER DATABASE ADD [STANDBY] LOGFILE [THREAD integer] [GROUP integer] [REUSE] SIZE filespec;
