If you wish to use Sybase IQ as an Open Server, you must ensure that it is started using the TCP/IP protocol.
See ”Starting the database server as an Open Server” in SQL Anywhere Server - Database Administration.
Every application using TCP/IP on a machine uses a distinct TCP/IP port, so that network packets are sent to the correct application. The default port for Sybase IQ is port 2638, which is used for shared memory communications. You can specify a different port number:
start_iq -x tcpip{port=2629} -n myserver iqdemo.db
