Introduction:

 

Oracle Enterprise Manager Grid Control 11g with Oracle WebLogic Server Management Pack Enterprise Edition’s capabilities includes Exalogic-specific management tools to monitor Oracle software deployed in the Exalogic environment. These monitoring capabilities expand on the existing Oracle WebLogic Server management features that span the following:

  • Application performance management
  • Configuration management
  • Service-level management and operations

These features improve the performance and availability of Java applications and web services, avoid downtime, and reduce cost by automating manual and error-prone operations. The following are the new Exalogic-specific features offered by Oracle Enterprise Manager Grid Control:

  • View an Exalogic dashboard that shows the overall health, availability, and performance of all applications, Oracle WebLogic domains, and hosts running on Oracle Exalogic machine.
  • Drill down into application deployments to identify metrics and set thresholds.
  • Display alerts, policy violations, and incidents hierarchically across the Exalogic environment and provide operations with instant notifications in relation to service levels and thresholds.
  • Contextually drill down from the Exalogic dashboard and underlying menus into the detailed component and JVM-level performance metrics, configuration management, and provisioning and cloning that provide end-to-end management for operations and administrators.
