Hello Rob I have deployed RSU2601 on zos 3.1.
Whenever I am trying to use MXI features like APF, LNK, LPA,LPD .Post that when I come out of the MXI panel and try to use TSO NETSTAT or TSO OMVS , I receive CEE5101C DURING INITIALIZATION, the callable service BPX1MSS failed. The System return code was 0000000156, the reason code was 0D070200. finally it ends with U4093 Reason code 90 This error message comes up immediately after I exit from MXI panel. Not sure if MXI is causing this but I have opened a case and still IBM has not found the offending module yet. Not sure what SLIP traps would help in this scenario I have a valid OMVS UID, GID. Infact we never got this error prior to RSU2601 within zos 3.1 but not sure what changed. Definition wise all the privileges my racf ID has, but only the difference what I see is RSU2601 which was rolled out and post that we are seeing this behaviour Any pointers are much appreciated Regards Peter On Tue, 12 May 2026, 12:42 Rob Scott, < [email protected]> wrote: > Peter, > > If you are referring to the freeware MXI 4.3, then it will probably work > just fine in the most part. > > Please note that the code has not been updated for over 20 years and is > not currently supported by myself (or Rocket Software).
