文档解释

ORA-19550: cannot use backup/restore functions while using dispatcher

Cause: Attempted to use backup/restore functions while connected to the dispatcher in a shared server. This is not allowed because the device that is used for backup and restore must remain allocated to a single process.

Action: Connect directly to the instance then re-execute the backup or restore function.
