    PRODUCT:  z/TPF
    FUNCTIONAL AREA:  TOD CLOCK RPQ SUPPORT

    COMMENTS:
    APAR PJ39209 provided the SSTP parameter on the ZATIM xxxx TOD
    GOOD SSTP command. When SSTP is used, all TPF processors in the
    loosely coupled complex use a local TOD clock.
    When PJ39209 was introduced, the display for command ZDTIM TOD
    was not updated. This can lead to confusion. If the sysplex
    timer is attached to the machine and TPF is using the SSTP
    option, ZDTIM TOD will show that the sysplex timer is being
    used. The machine may be using the sysplex timer, but the TPF
    LPAR is not handling interrupts from the sysplex timer. In this
    case the ZDTIM TOD display should show that the TOD is local.
    

Problem conclusion

  • SOLUTION:
    The display for ZDTIM TOD has been updated. If the SSTP option
    is being used (ZATIM xxxx TOD GOOD SSTP was input), ZDTIM TOD
    will show the TPF LPAR as local. Also, the ZDTIM TOD output
    will have a line saying "SSTP OPTION IN USE".
    In addition, a user area is added to the BSS clock record.
    Files base/macro/st0tm.mac and base/include/tpf/c_st0tm.h have
    been updated to allocate space for use by customers.
    
    COREQS: NO
    None.
    
    MIGRATION CONSIDERATIONS: NO
    None.
