The server did not start the specified administrative session because the administrator connected to the server on the server port that is used for client sessions, and the option ADMINONCLIENTPORT is set to NO. When different port numbers are used for administrative and client sessions (controlled by the TCPPORT and TCPADMINPORT options), and option ADMINONCLIENTPORT is set to NO, administrative sessions can be started only on the port used for administrative sessions (as specified by the TCPADMINPORT option).
Server operation continues.
Update the client options file to specify the port to be used for administrative sessions. This is typically specified by the TCPADMINPORT option in both client and server option files.
