you to supply an exit which is specific to a particular server, or an exit that is used by all servers, forcustomization needs that cannot be met using a customized SYSTEM D<strong>TCP</strong>ARMS file. Changing server names (when defining a second set of <strong>TCP</strong>/<strong>IP</strong> servers, for example) no longerrequires changes to <strong>IBM</strong>-provided execs. All information related to the user ID of a particular server iskept in the <strong>TCP</strong><strong>IP</strong> DATA file, or is part of the server configuration and is maintained in theD<strong>TCP</strong>ARMS file. External Security Manager (ESM) interfaces have been standardized across all servers. TheRPIUCMS command is used to initialize the RACROUTE environment, and RPIVAL is used to validateuser IDs and passwords supplied by clients. These commands can be changed using a customizedSYSTEM D<strong>TCP</strong>ARMS file. The ESM environment is automatically established for a server when :ESM_Enable.YES is specified forthat server in a customized SYSTEM D<strong>TCP</strong>ARMS file.Refer to the chapter titled “<strong>TCP</strong>/<strong>IP</strong> Server Configuration” in z/<strong>VM</strong>: <strong>TCP</strong>/<strong>IP</strong> <strong>Level</strong> 3A0 Planning andCustomization for more information.5.2.4.3 <strong>TCP</strong><strong>IP</strong> Server5.2.4.3.1 Changes Introduced in <strong>TCP</strong>/<strong>IP</strong> Function <strong>Level</strong> 320 The TIMESTAMP statement default has been changed from TIMESTAMP 0 to TIMESTAMP PREFIX,which specifies that a time stamp is to preface every trace and console message. This change helpsin diagnosing problems and isolating error conditions. Therefore, it is recommended that any existing<strong>TCP</strong>/<strong>IP</strong> server configuration files be changed to specify TIMESTAMP PREFIX to aid in problemdetermination. The Telnet session connection exit interface has been changed to pass the LU name supplied by aclient (if any) as an additional parameter. Existing exits may need to be changed to accommodate thisbehavior. The Telnet printer management exit is called for any printer session, regardless of whether the clientLU name and <strong>IP</strong> address are defined by a TN3270E statement in the <strong>TCP</strong>/<strong>IP</strong> configuration file.Existing exits may need to be changed to accommodate this behavior.5.2.4.4 RouteD/MPROUTE Server5.2.4.4.1 Changes Introduced in <strong>TCP</strong>/<strong>IP</strong> <strong>Level</strong> 3A0 The RouteD and MPROUTE servers cannot be concurrently used with the same <strong>TCP</strong>/<strong>IP</strong> stack server.5.2.4.4.2 Changes Introduced in <strong>TCP</strong>/<strong>IP</strong> Function <strong>Level</strong> 320 The #CP EXTERNAL command can no longer be used to terminate RouteD server. The command tostop RouteD is #CP SMSG * SHUTDOWN.Installation Requirements and Considerations 15
