· 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.
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>...
