The comments in the job explain it: //**************************************************************** //* SMS IS ACTIVATED IN A NULL CONFIGURATION TO ALLOW TCP/IP TO //* DYNAMICALLY ALLOCATE Z/OS UNIX FILES. WITHOUT IT SOME TCP/IP //* FUNCTIONS THAT REQUIRE TO READ THEIR CONFIG FILES FROM UNIX //* VIA DYNALLOC WITH PATHNAME WILL FAIL (RC=4, ERRORCODE=04D0) //* (/ETC/SERVICES IS REQUIRED FOR INETD FOR EXAMPLE AND CAN'T //* BE READ). THIS ISN'T REQUIRED FOR A "RESCUE" SYSTEM, BUT IS //* INCLUDED IN THE CONFIGURATION ANYWAY AND ALLOWS TELNET INTO //* Z/OS UNIX IF DESIRED (AND CONFIGURED). //**************************************************************** You can find my "rescue system" samples on my web site in the JOBs section: http://home.flash.net/~mzelden/mvsutil.html Anyway, a null configuration is one where you allocate an empty ACDS and COMMDS and have an IGDSMSxx member that points to them and start SMS via IEFSSNxx. A minimal configuration is where you define the base configuration via ISMF and also at least one STORCLAS, one storage group (with at least 1 volume), and ACS routines for the storage class and storage group (DATACLAS and MGMTCLAS are not required). If you've been around a while, you may recall that ServerPac used to come with instructions and samples for an SMS minimal configuration around the time of OS/390 because HFS files had to be SMS managed. So many shops that never used SMS were forced to create the minimal configuration in order to bring up OMVS.
