RAC with BR*Tools

Use

You can manage up to 16 parallel  instances of the Oracle Real Application Cluster (RAC) with BR*Tools. You normally start these tools only on the dedicated database (DDB) instance.

Prerequisites

·        Check the requirements in Oracle Real Application Cluster (RAC).

·        The necessary BR*Tools executables must exist on the DDB instance host in directory /usr/sap/<SAPSID>/SYS/exe/run.

·        A common spfile must exist on the DDB instance host in directory <ORACLE_HOME>/dbs (UNIX) or <ORACLE_HOME>\database (Windows).

·        The backup devices (tape units or hard disks) are normally connected locally to the DDB instance host.

Activities

If you have set up the user SYSTEM correctly, it now has the authorization to start and stop the database instances remotely. Therefore, you can call BRBACKUP and BRARCHIVE as usual, for example:

brbackup -u system/<password>...

brarchive -u system/<password>...
