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。

shared server configuration, as indicated by (

SERVER=shared)

.

(DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp)(HOST=sales-server)(PORT=1521))
(CONNECT_DATA=
(SERVICE_NAME=sales.us.acme.com)
(SERVER=shared)))

If you want the client to use a dedicated server, you can specify 

(SERVER=dedicated)

 in place of 

(

SERVER=shared)

.
If the 

SERVER

 parameter is not set, then shared server configuration is assumed. However, the client will use a dedicated server if no dispatchers are available.
