# RELEASE CHANNEL

Syntax

release::=

Description of the illustration release.gif

Purpose

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.

Restrictions and Usage Notes

Execute this command only within a RUN block. See "releaseForMaint" for the form of `RELEASE CHANNEL` used for maintenance channels.

Examples

Releasing a Channel: Example This example makes three identical backup sets of datafiles `1` to `4` to tape with channel `ch1`, then releases it. RMAN then makes three identical backups of datafiles `5` to `7` to tape with channel `ch2` and then releases it:

    RUN {
         SET BACKUP COPIES = 3;
         ALLOCATE CHANNEL ch1 DEVICE TYPE sbt FORMAT 'bkup_%U';
         ALLOCATE CHANNEL ch2 DEVICE TYPE sbt MAXPIECESIZE = 5M;
         BACKUP CHANNEL ch1 DATAFILE 1,2,3,4;
         RELEASE CHANNEL ch1;
         BACKUP DATAFILE 5,6,7;
    }
