The Internet daemon (INETD) server must be started in order for a node to be added or started, as well as for merge partition processing.
It is recommended that the INETD server always be running in your cluster.
The INETD server can also be started using the STRTCPSVR (Start TCP/IP Server) command and specifying the *INETD parameter. When the INETD server is started, a QTOGINTD (User QTCP) job will be present in the Active Jobs list on the subject node.
