Object documentationRAC with the init<DBSID>.sap Profile

 

This section contains information on the profile init<DBSID>.sap for the Oracle Real Application Cluster (RAC).

 

  • dd_flags and dd_in_flags

    You must install the RAC database on a cluster file system or raw devices. If installed on raw devices or in Oracle ASM, the backup runs using the dd command. Therefore, make sure that you set the parameters dd_flags and dd_in_flags, which specify the required dd command. See Raw Devices with BRBACKUP and BRRESTORE.

    Note Note

    You do not need to set this parameter if you use external backup tools to back up your database, with the following setting for backup_dev_type:

    backup_dev_type = util_file | util_file_online|util_vol|util_vol_online.

    End of the note.

  • parallel_instances

    This parameter defines the instances running in parallel to the DDB instance.

    Caution Caution

    All database instances (including the local one, DDB) must be specified in the list of instance descriptions.

    End of the caution.

  • db_services

    This parameter activates the handling of database cluster services by BR*Tools.
