Standby creation via RMAN Duplicate recipe requires the auxiliary database to be statically registered with a listener. If the user wants the standby to be registered with a Grid Infrastructure listener, the static registration of the auxiliary will be performed to a temporary listener that will be created on a random port and this listener will be deleted after the RMAN Duplicate is completed successfully such that the database will later be dynamically registered with the Grid Infrastructure listener.
In scenarios where the users would like to block all the ports (for respective security purposes), the creation of temporary listener will fail and hence RMAN Duplicate database step will fail.
