In the case of a TCP/IP interconnection, the transport system address of a local openFT instance consists of the Internet address, port number and T-selector.
The Internet address of the z/OS system on which the local openFT instance is running is assigned using the HOST NAME parameter in the FJGEN command (see FJGEN - Set installation parameters). In HOST NAME, you should always directly specify the IP address or the host name. Multiple parallelly running openFT instances must have different IP addresses. Please note that you may only use IP addresses that are defined in your z/OS system’s address space.
The port number of the openFT (z/OS) main station (passive port) is defined using the OPENFT-APPL parameter in the FTMODOPT command. We strongly recommend to use the default port number 1100. This is predefined as default in all openFT products and therefore greatly simplifies addressing in a heterogeneous environment.
The T-selector of the openFT (z/OS) main station has the name $FJAMbbb (b = blank).
