Functionality
Oracle Enterprise Manager performs much of its activity through intelligent agents which Oracle Corporation refers to as Oracle Management Agents. These run as autonomous proxy processes on a managed node, and perform execution and monitoring tasks for Oracle Enterprise Manager, communicating using the Hypertext Transfer Protocol (HTTP or HTTPS). Oracle Release 10g has 14 additional packs (plug-ins) which require separate licensing. By default, upon installation, the OMA enables several packs (Change Management, Performance & Tuning, Diagnostics and Configuration Management) without any regard to what a customer has licensed. Users need to de-select unlicensed packs after installing the agent on a target database.
