Categories of Service Group Dependencies

Dependency categories determine the relationship of the parent group with the state of the child group.

Online Group Dependency

In an online group dependency, the parent group must wait for the child group to be brought online before it can start. For example, to configure a database application and a database service as two separate groups, you would specify the database application as the parent, and the database service as the child. The following illustration shows an online local soft dependency (described in Soft Dependency).

Offline Group Dependency

In an offline group dependency, the parent group can be started only if the child group is offline and vice versa. This prevents conflicting applications from running on the same system. For example, to configure a production application on one system and a test application on another, the test application must be the parent, and the production application must be the child. An offline local dependency prevents the test and production applications from coming online on the same system at a time.
