The transport system address of a TCP/IP partner system consists of the Internet address of the remote computer, the T-selector of the remote FT system and, where appropriate, the port number of the RFC1006 implementation of the remote FT system if this differs from the default port number 1100. The transport system addresses of all partner systems which are to be accessed via TCP/IP must be reported to openFT (z/OS). This has been considerably simplified as of openFT V10:
The FT administrator enters the partner systems in the partner list with the FTADDPTN command and stores the necessary address information there. For further details on specifying addresses, see the manual "openFT (z/OS) - Command Interface".
If host names are used, it must be possible to determine the associated IP address from the relevant data source, e.g. from the file TCPIP.HOSTS.LOCAL or using DNS.
If dynamic partners are permitted (see FTMODOPT command), it is also possible to directly address a partner system of this type without it being entered in the partner list.
