Example 2-42 Overriding the Default Device Type
This example configures duplexing to
data files and control files (control file autobackups on disk are a special case and are never duplexed), then configures
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 2;
CONFIGURE CHANNEL DEVICE TYPE sbt PARMS 'ENV=(OB_DEVICE_1=tape1)';
CONFIGURE DEFAULT DEVICE TYPE TO sbt;

DEFAULT DEVICE TYPE TO deviceSpecifie | Specifies the default device type for automatic channels. By default, DISKis the default device type. CLEARreturns the default device type to DISK. By default, the BACKUPcommand only allocates channels of the default device type. For example, if you configure automatic channels for DISKand sbtand set the default device type to sbt, then RMAN only allocates tape channels when you run the BACKUP DATABASEcommand. You can override this behavior either by manually allocating channels in a RUNcommand, or by specifying DEVICE TYPEon the BACKUPcommand itself (seeExample 2-42). The RESTOREcommand allocates automatic channels of all configured device types, regardless of the default device type. The RESTOREcommand obeys the PARALLELISMsetting for each configured device type. |
This example configures duplexing to
2for
DISKbackups of
data files and control files (control file autobackups on disk are a special case and are never duplexed), then configures
sbtas the default device.
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 2;
CONFIGURE CHANNEL DEVICE TYPE sbt PARMS 'ENV=(OB_DEVICE_1=tape1)';
CONFIGURE DEFAULT DEVICE TYPE TO sbt;
