Oracle Enterprise Manager provides a central point of control for the Oracle RAC environment, allowing you to perform administrative tasks simultaneously on multiple cluster databases. Based on the Oracle Enterprise Manager Cloud Control (Grid Control in Oracle Enterprise Manager 11g) graphical user interface (GUI), you can manage both non-clustered and Oracle RAC environments.
In Oracle Enterprise Manager, Oracle RAC-specific administrative tasks generally focus on two levels: tasks that affect an entire cluster database and tasks that affect specific instances. For example, you can use Oracle Enterprise Manager to start, stop, and monitor databases, cluster database instances, and their listeners, and to schedule jobs or set up alert thresholds for metrics. Or you can perform instance-specific commands such as setting parameters or creating resource plans. You can also use Oracle Enterprise Manager to manage schemas, security, and cluster database storage features.
