Oracle Error Message

RMAN-05519: WARNING: tablespace string is always included when duplicating

Reason for the Error

The SYSTEM and SYSAUX tablespaces were included in the DUPLICATE TABLESPACE command. They were automatically included by the command and did not need to be explicitly named.

Solution

To avoid this warning,, remove the SYSTEM and/or SYSAUX tablespace from the tablespaces list and retry the operation.
