release::=
To release a channel while maintaining the connection to the target database instance. Specify the channel name with the same identifier used in the ALLOCATE CHANNEL command. This command is optional because RMAN automatically releases all channels allocated when a RUN block terminates.
Execute this command only within a RUN block. See "releaseForMaint" for the form of RELEASE CHANNEL
used for maintenance channels.
