Perform this step only if you have not already configured VVR during the installation.
By default, the installer installs the required VVR configuration files irrespective of whether or not you choose to enable VVR. To configure VVR manually in SF Oracle RAC, simply start VVR using the vxstart_vvr command . The command starts the VVR daemons and configures the ports. You may change the default settings at any time.
For instructions on changing the default settings, see the Veritas Volume Replicator Administrator's Guide.
