It is designed to help you manage your individual application server instances, application server farms (an Application Server grouped with its corresponding infrastructure), and Oracle Application Server clusters. From the Application Server Control, you can monitor the entire Oracle Application Server platform ”from J2EE to Portal and Wireless to Business Intelligence components ”and perform administrative tasks , such as configuration changes to your application server components and real-time monitoring of all services configured in your Application Server 10 g instances. With Enterprise Manager 10 g Application Server Control, administrators can:

• Manage and configure application server components
