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

 

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

Cause	An attempt was made to use backup/restore functions while connected to the dispatcher in a multi-threaded 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.

因db配置为MTS，修改tnsnames.ora文件把connect mode改为dedicated即可。
