The AdminServer uses the Java Remote Method Invocation (RMI) interface to communicate with OpenEdge resources, such as the NameServer, OpenEdge DataServer for Oracle, and OpenEdge DataServer for MS SQL Server and management tools, such as DBMAN.

By default, the RMI interface is enabled only for local communication between AdminServer and OpenEdge resources. However, you can enable it for remote communication using the enableRemoteRMI property.

The RMI interface listens on the default port, 20931, of AdminServer and you can change this port if needed. For information on changing the default port, see Change the default AdminServer port.
