db2cli.ini keyword syntax:: ServiceName = service name | port number

Usage notes:

Use this option in conjunction with the Hostname option to specify the required attributes for a TCP/IP connection from this client machine to a server running DB2®. These two values are only considered when the PROTOCOL option is set to TCPIP.
