Configuring RMAN Channels for Use in Oracle Database Duplication
RMAN channels perform the primary job of database duplication
Each channel corresponds to an Oracle Database server session that performs the duplication tasks. Depending on the duplication technique, RMAN uses either auxiliary channels or target channels.
-
Automatically allocate channels by using the
CONFIGURE
command -
Manually allocate channels by using the
ALLOCATE
command
If no automatic channels are configured, then you can manually allocate at least one channel before you begin the duplication. The ALLOCATE
command that allocates channels must be in the same RUN
block as the DUPLICATE
command.
RMAN can use the same channel configurations on the source database for duplication on the destination host even if the source database channels do not specify the AUXILIARY option.
