Error description

  • A CICS system dump is formatted using the CICS dump formatter
    with the SO=1 option specified.  After printing the list of
    sockets in the first socket pool the output ends with:
    
    ** DFHPD0123 A program check has occurred while processing
    keyword SO
    
    This is also applicable with option SO or SO=3.

    *                      the CICS dump formatter with the S0=1,  *
    *                      SO=3 or SO option specified.  After     *

    *                      occurred while processing keyword SO    *
    ****************************************************************
    When a CICS system dump is formatted using the CICS dump
    formatter with the SO=1, SO=3 or SO option, and one or more
    socket pools contain active sockets, the formatter prints the
    socket pool summary table correctly but fails when attempting to
    print the individual sockets within each pool. The failure is
    recorded as message "** DFHPD0123 A program check has occurred
    while processing keyword SO", after which the remaining socket
    detail output is not produced. The problem occurs in CICS dumps
    where socket pooling is active and sockets are retained in a
    pool rather than closed immediately.
    

Problem conclusion

  • The module DFHSOCO has been corrected to resolve the issue.
