Backing up an Oracle Data Guard environment

Below an example of an RMAN script that allocates two channels and performs a database backup.

run {

allocate channel 'dev_0' type 'sbt_tape'

parms='ENV=(OB2BARTYPE=Oracle8,OB2APPNAME=DG1, OB2BARLIST=OraSTBY_DG1,

OB2BARHOSTNAME=oracle1)';

allocate channel 'dev_1' type 'sbt_tape'

parms='ENV=(OB2BARTYPE=Oracle8,OB2APPNAME=DG1, OB2BARLIST=OraSTBY_DG1,

OB2BARHOSTNAME=oracle1)';

backup incremental level 0

format 'OraSTBY_DG1<DG1_%s:%t:%p>.dbf'

database;

}

Make sure that the number of allocated channels is the same as the number of backup devices and

their concurrency settings.

In case 2 backup devices should be used and each device can deal with 2 parallel streams, then 4

channels have to be allocated within the RMAN script.
