--error 1004 EIBMIUCVERR IUCV error (then init socket error...) at CFT installation timeResolution
--The UserID is missing a OMVS segment
--OMVS segment is require to be up to use TCP/IP sockets since OS/390 2.5 and above
Note:
Any address space using TCP/IP sockets (since OS/390 2.5 and above) must have an OMVS segment, so that it has a valid UNIX UID, GID, and home directory. Generally, sites set up a default UID for this, so that every TCP/IP address space doesn't require a OMVS segment.
Check RACK ADDGROUP DEFGROUP OMVS(GID(777777))
Tips:
Verify the userid can open a session on the OMVS side and have access to USS, if not, ask the security guy to add the OMVS segment.
