Configuring Oracle RMAN backups with HP Data Protector to use deduplication on the VLS

It is important that the % parameters are configured in exactly this sequence using exactly these

separators:

<DB_NAME_%s:%t:%p:%f>.EXTENSION

• DB_NAME: ORACL in the example above.

• %f is not available for archivelog.

• EXTENSION: .df (for data files), .al (for archive logs) or .cntrl (for

the controlfile)

The backup must include the controlfile backup. This can be configured within Oracle RMAN configuration

as a default option or by adding the following two RMAN statements right at the beginning:

CONFIGURE CONTROLFILE AUTOBACKUP ON;

CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE 'SBT_TAPE'

TO '%F';

Note:

It is mandatory to enable the auto backup of the controlfile. If not enabled,

Oracle will automatically include the SPFILE in the backup which leads to a

format error as the “%f” parameter is not supported for the SPFILE.

See below the complete script:

run {

CONFIGURE CONTROLFILE AUTOBACKUP ON;

CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE 'SBT_TAPE' TO

'%F';

allocate channel 'dev_0' type 'sbt_tape'

parms 'ENV=(OB2BARTYPE=Oracle8,OB2APPNAME=ORACL,OB2BARLIST=oracle backup

specification)';

allocate channel 'dev_1' type 'sbt_tape'

parms 'ENV=(OB2BARTYPE=Oracle8,OB2APPNAME=ORACL,OB2BARLIST=oracle backup

specification)';

allocate channel 'dev_2' type 'sbt_tape'

parms 'ENV=(OB2BARTYPE=Oracle8,OB2APPNAME=ORACL,OB2BARLIST=oracle backup

specification)';

allocate channel 'dev_3' type 'sbt_tape'

parms 'ENV=(OB2BARTYPE=Oracle8,OB2APPNAME=ORACL,OB2BARLIST=oracle backup

specification)';
