The full RAC installation is covered in the Dbvisit Standby User Manual. See http://www.dbvisit.com/documentation.php

The Dbvisit Standby RAC installation specifics are:
The Dbvisit Standby RAC installation is just like a normal Dbvisit Standby installation. The major difference is:

- Dbvisit Standby needs to be installed and configured on every primary RAC node (dbvisit_setup needs to be run on every RAC node).

- During dbvisit_setup, choose the name of the instance as the ORACLE_SID and not the database name.

- Ensure there is an entry in the /etc/oratab file for each RAC node. If the RAC nodes are called RACDB1 and RACDB2, and the database is called RACDB then the oratab (on each RAC node) should look like:
RACDB:/oracle/orabase/product/10.2.0/db_1:N
RACDB1:/oracle/orabase/product/10.2.0/db_1:N
RACDB2:/oracle/orabase/product/10.2.0/db_1:N

- When the dbvisit_setup programs asks if this is a RAC installation, answer YES. For Dbvisit Standby 5.1 choose option 1a in dbvisit_setup to install RAC.

- The Dbvisit Standby repository only needs to be installed on one RAC node (option 4 in dbvisit_setup). This will then be installed in the database for all RAC nodes to use.

- Dbvisit Standby needs to be scheduled separately on each node. The name of the instance is used when installing and running Dbvisit Standby, not the name of the database.

- The Dbvisit Standby Database Configuration file (DDC) created during the setup on each node will have the name of the instance and not the database (dbv_oracle_instance.env). If the database is called RACDB and has the following instances RACDB1 and RACDB2, the DDC files will be called:
dbv_RACDB1.env
dbv_RACBD2.env

- With a single instance standby database, Dbvisit Standby is scheduled on the standby server using the instance name from one of the primary nodes. Example: if the RAC configuration has 2 instances called RACDB1 and RACDB2 and the standby database is called RACDB, then Dbvisit Standby is executed on the standby server using the command:
dbvisit RACDB1

ASM
There is nothing to configure for ASM. Dbvisit Standby will automatically detect that you are using ASM.
