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

Oracle Error Message

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

Reason for the Error

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.

Solution

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