It may be necessary occasionally to trouble shoot the Vantage software. Programs are provided to enable you to determine if the problem can be resolved locally or if a call to Vantage Technical support is required. What follows are some common problems with possible solutions.
When starting a resource the console window is blank (no V_multiplex initiated message) and pressing return in the window does not result in a system prompt.
This is typically a problem with the Vantage process stack not coming down properly. The diag1 program can be used to determine which process is hung. Type recover [resource_name] to remove hung processes. If the same condition results when Start Console is done call Vantage Technical Support.
Events that should have resulted in a Message event or Message with Reply event response have occurred but no messages were displayed.
Execute the listawide program to determine if the event was detected. For example, if the event to be detected is ON TAPE NUM(?) execute the command listawide | grep "ON TAPE NUM(?)". The listawide program will output all lines in the broker log that contain the string.
Make sure that the event was detected on the correct resource, that the ExeFlag field contains a 0 (always execute) and the Action field is either a 1 (Message event), a 7 (Message with Reply) or an 8 if the messages are executed from an API Exec event. If these conditions are true, then the event was detected properly.
The next step is to make sure that the vanrpc_disp process is running. Execute the diag1 program and check the VANTAGE RPC SECTION to verify that both the vanrpc_serv and vanrpc_disp processes are running. If the vanrpc_disp is not running it can be executed from a terminal window by typing vanrpc_disp.
If necessary to execute the vanrpc_disp program from a terminal window the window must remain running (it can be minimized but not closed). As soon as practical, all resources should be stopped (Stop All Cons), the Broker stopped (Stop Broker) and the resources restarted (Start All Cons). This will ensure that the broker and the vanrpc_disp processes are synchronized. If the problem is not resolved by these steps call Vantage Technical Support.
