Hello, When I have seen this abend, "USER COMPLETION CODE=4093 REASON CODE=00000090" and that the UserID is trying to run TCP/IP command like TSO NETSTAT, then the issue has been the UserID doesn't have an OMVS segment.
Yes, even if NETSTAT is running using TSO NETSTAT, it is my understanding that all TCP/IP work is running in USS.
