Examples

Releasing a Channel: Example

in this example, RMAN allocates channels ch1 and ch2. It then makes three identical backup sets of datafiles 1 to 4 to tape, then releases it. RMAN then uses channel ch2 to make three identical backups of datafiles 5 to 7 to tape, 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; 
}
