-109 ERR CNCT REFUSED RT (Magic xpa 3.x)
Connection problems between requesters and enterprise servers.
Check the firewall settings between the client and server computers, host name resolving, etc.
You can view the Broker monitor to view the status of the enterprise servers. Ping the host name and IP address of the assigned enterprise server.
Verify that the engine is alive; for example, in the Task Manager, according to the PID displayed in the broker’s status window. Call this engine from a command line requester, in order to isolate the source of the problem. (Connections are created and destroyed for each request of the command line requester.)
Verify that the application runs correctly; for example that the database is correctly defined.
