The OEM Console

The Oracle Enterprise Manager Central Console is a web-based interface for managing the entire enterprise from the console. It offers a lot more functionality than the standard Oracle Enterprise Manager that comes with a typical database install. The default ports for running in a non-secure mode are 7777-7877; default ports for running in a secure mode are 4443-4533.

You can access the OEM Central Console from the following URLs: http://<oms hostname>.<domain>.<port>/em and https://<oms hostname>.<domain>.<port>/em. The OEM Central Console requires the Oracle Management Service unless the Oracle Management Agent is installed separately.

The OEM Components

The OEM console uses the following components, which are installed with the Oracle application server:

Image The Oracle Management Service A web-based application that runs on the Oracle application server. It provides the user interface for the OEM console, and interfaces with the management agents to process and monitor information.

Image The Oracle Management Agent Monitors information from sites that need to be managed and which are loaded into the management service.

Image The Oracle Management Repository Contains all the information managed by the Oracle Enterprise Manager.

Before installing the Complete Enterprise Manager, make sure to read the requirements for the complete installation that includes the Oracle Application Server 10g, Web Cache, and the Management Service application.

The Oracle Net Configuration Assistant

The Oracle Net Configuration Assistant is used during installation to configure the basic network components. The Oracle Net Configuration Assistant can also be run standalone to modify the same values configured during installation. Configurable components include the following:

Image Naming methods

Image Net service names (tnsnames.ora)

Image Listener names and protocol addresses

Image Directory server usage
