You can choose to configure the service group in a way that insulates all the databases from failure in any of the databases in the group.
VCS manages the start and stop sequence of the applications and the database.

Note:

In a setup with multiple databases, you must configure the database under VCS. The configuration without the VCS Oracle agent may be used only in single database setups.

You can create Oracle service groups by modifying the VCS configuration file in one of the following ways:

Edit the main.cf file
