channel (Oracle specific term) An Oracle8/9 Recovery Manager resource allocation. Every allocated channel starts a new Oracle8/9 process, which performs backup, restore, and recovery actions. The type of channel allocated determines the type of media used:

•type “disk”

•type ‘SBT_TAPE’

If the specified channel is type ‘SBT_TAPE’ and Oracle8/9 is integrated with Data Protector, the server process will attempt to read backups from or write data files to Data Protector.
