Port 5151

ESRI SDE Remote Start operates over UDP port 5151 and is leveraged within ESRI's ArcGIS environments, primarily to manage spatial database engines remotely. ArcSDE (Spatial Database Engine) essentially acts as a middleware that allows geographic features to be stored inside relational databases like Oracle, SQL Server, PostgreSQL, and DB2. The Remote Start service enables administrators and GIS applications to initiate the ArcSDE processes without direct access to the server shell, improving remote management capabilities.

The service communicates using UDP for lightweight, connectionless communication that supports quick status queries and remote commands essential for controlling spatial database processes. It integrates with the ESRI client tools and APIs for effective orchestration across the network.

Deployments of SDE Remote Start typically complement complex GIS solutions that require high availability and efficient resource management. By utilizing dedicated ports such as 5151, organizations optimize their workflows and maintain reliable access to geospatial data repositories, especially critical for large distributed teams relying on synchronized mapping data.
