Manually Allocating RMAN Channels

We can manually allocate RMAN channels inside a run block by using the allocate channel command.

Example:

run
{
allocate channel disk1 device type disk format '/disk1/rman_backups/%U_%t_%T';
allocate channel disk2 device type disk format '/disk2/rman_backups/%U_%t_%T';
allocate channel disk3 device type disk format '/disk3/rman_backups/_%U_%t_%T';
backup database plus archivelog;
}
