1 Overview of Enterprise Manager Grid Control

This chapter provides an overview of Enterprise Manager Grid Control and helps you understand its architecture and the various core components that are integrated within the product.

This chapter contains the following sections:

Overview of Enterprise Manager Grid Control

Enterprise Manager Grid Control is a system management software that delivers centralized monitoring, administration, and life cycle management functionality for the complete IT infrastructure, including systems running Oracle and non-Oracle technologies. Your infrastructure may comprise multiple Oracle Databases, Oracle WebLogic Managed Servers, Web applications deployed on these servers, hosts running these targets, and so on. You can, of course, use the individual product consoles to monitor the status of each of these targets, but it becomes cumbersome to shuttle between multiple console windows and track the performance of each of these targets using so many windows.

Enterprise Manager Grid Control offers a solution that allows you to monitor and manage the complete Oracle IT infrastructure from a single console. Enterprise Manager Grid Control also offers support for monitoring certain non-Oracle products, for example, IBM WebSphere Application Server, Microsoft SQL Server, Juniper Networks NetScreen Firewall, and so on.

With a broad set of end-to-end monitoring, administration, configuration management, provisioning, and security capabilities, Enterprise Manager Grid Control reduces the cost and complexity of managing such grid computing environments. Robust service-level management functionality within Enterprise Manager Grid Control dramatically improves service levels through rich transaction and end-user performance monitoring and deep diagnostics for multi-tier Internet applications.

After installing Enterprise Manager Grid Control, what you see is the Enterprise Manager Grid Control Console, the user interface that displays information about the health of the monitored targets. However, internally, OMS orchestrates with Management Agents to discover targets, monitor and manage them, and store the collected information in a repository for future reference and analysis.
