Configuring multiple Oracle instances in VCS using multiple runs of the wizard

If you are configuring the first Oracle instance on a machine where more than one instance is running, you can configure it by following the steps in the Configuring a single instance/multiple instances in VCS section.

The High Availability Configuration wizard will not allow you to configure the next Oracle instance if any of the mandatory dependent resources such as mount point, disk group, disk, and listener are already configured in VCS.
