3.3 EM2Go

Although EM2Go isn't part of Oracle Application Server itself, Oracle Application Server administrators will find this product very helpful in monitoring their targets while on the run. EM2Go is the mobile component of Oracle Enterprise Manager 10 g . It facilitates administrator access to a subset of the Oracle Enterprise Manager functionality through a Pocket PC browser on a PDA device.

Because EM2Go leverages the architecture of Oracle Enterprise Manager 10 g , no additional infrastructure is required to start using the product. EM2Go includes the following:

• Oracle Management Service, a J2EE web application hosted by Oracle Application Server 10 g

• A Management Repository for its persistent data store

• Distributed, lightweight Oracle Agents that monitor all services on the host and execute remote operations on managed services

Communication between EM2Go and Oracle Management Service, and between Oracle Management Service and the Agents, is performed via HTTP or HTTPS.

Oracle Enterprise Manager automatically gathers and evaluates diagnostic information from Oracle Application Server systems distributed across the enterprise. As with all services managed by Oracle Enterprise Manager, an extensive array of Oracle Application Server performance metrics are automatically monitored against predefined thresholds, and alerts are generated when metrics exceed these thresholds. The EM2Go home page displays all the alerts, enabling the administrator to drill down into the alert details to investigate what triggered the problem. Using EM2Go, the administrator can monitor the availability of the application servers. The diagnostic reports for CPU usage and memory usage are also available from your device, providing a graphical view of current or historical data.
