Oracle Error Message
RMAN-06412: no proxy copy channel found
Reason for the Error
A proxy copy was started, but no allocated channel supports proxy copy. This could be because the media management software used by the target database does not support proxy copy, or because all of the allocated channels are of type DISK, which never support proxy copy.
Solution
If this is a backup, then either allocate a non-disk channel, or do not use the PROXY option. If this is a restore, then a channel of the same type which created the proxy backup was allocated, but now does not support proxy copy. If proxy copy is no longer supported by the media management software at the target database, the CROSSCHECK or CHANGE commands should be used so that those backups will not be considered for further restores.
