IQPORT overrides the default value for the Sybase IQ Agent port number, which is used for communications between the Sybase IQ plug-in and Agent.
Once the agent starts, you cannot change the port value.
1099 is the plug-in default value when searching for an agent process on any given port. If the plug-in finds no agent on this port, it displays a prompt so that you can specify the correct port value.
