Problem summary

  • ****************************************************************
    * USERS AFFECTED: All CICS users.                              *
    ****************************************************************
    * PROBLEM DESCRIPTION: ABEND S0C4 observed for INQUIRE         *
    *                      TERMINAL request of IP-ECI task.        *
    ****************************************************************
    EXEC CICS INQUIRE TERMINAL is issued by an IP-ECI program that
    is coming into CICS through a TCPIPSERVICE from a CTG client.
    The task ends with TERMIDERR and EIBRESP2 value as 1, indicating
    that the named terminal cannot be found.
    When the request is from external call interface, it points to
    IECCB(IP ECI Conversation Control Block) instead of TCTTE, and
    tries to search for IECCB address on TCTTE address chain. If not
    found then it correctly ends with TERMIDERR. However, an
    S0C4/AKEA may be observed in module DFHEIQST.
    

Problem conclusion

  • CICS has been changed to prevent the 0C4.
