Configuring TCPIP.DATA

The TCPIP.DATA configuration data set is the anchor configuration data set for the TCP/IP stack and all TCP/IP servers and clients running in z/OS®. With a z/OS TCP/IP stack, you can define the TCPIP.DATA parameters in a z/OS UNIX file or in an MVS™ data set. The TCPIP.DATA configuration data set is read during initialization of all TCP/IP server and client functions. All functions must access this data set in order to find basic configuration information, such as the name of the TCP/IP address space, the TCP/IP host name, and the data set prefix to use when searching for other configuration data sets. The TCPIP.DATA file contains the following major groups of configuration parameters:
