Oracle Error Message

RMAN-05019: WARNING: no channel of required type allocated to recover copy of datafile number

Reason for the Error

A RECOVER COPY command could not proceed because incremental backup sets exist on a device type that has not been allocated.

Solution

Use the LIST command to determine which device type is needed, then allocate a channel of that type.
