Port 3872

Oracle Management Remote Agent, operating typically on port 3872/TCP, is part of Oracle Enterprise Manager (OEM). OEM facilitates centralized monitoring, configuration, and management across multiple Oracle databases, middleware, hardware, and cloud assets. The remote agent serves as the communication bridge between Oracle servers and the management console, allowing administrators to perform tasks either manually or via automation.

The agent collects performance and health metrics, sends real-time alerts, and facilitates various administrative functions like patch deployment, cloning, and provisioning. It uses proprietary protocols optimized for secure, efficient data transfer and supports integration with scripting and automation tools, improving scalability of Oracle environments.

This service generally runs as a background process on the managed host, communicating back to the OEM console. Properly configuring network rules and agent settings is essential for seamless operation, minimal latency, and to avoid management disruptions across the enterprise system landscape.
