Error description

  • A logic error in the HourGlass AGGFRONT module causes the
    parameters for an SVC11 time request, usually supplied in GPR0
    and GPR1, to be overwritten and not restored.  Subsequently,
    control is given to the MVS native SVC11 processor, which
    returns an invalid result in GPR1 to the time requester.  When
    the time requester attempts to use the invalid result, an
    ABENDS0C7 results.

    ****************************************************************
    * PROBLEM DESCRIPTION: Correct logic in HourGlass module       *
    *                      AGGFRONT, near label @INCL1, that       *
    *                      results in GPR0 and GPR1, which are     *
    *                      supposed to contain the SVC11           *
    *                      parameters, to become corrupted.  Later *
    *                      in the process, control is passed to    *
    *                      the native MVS SVC11 processor with     *
    *                      GPR0 and GPR1 containing the invalid    *
    *                      data.  This results in an invalid time  *
    *                      value being returned to the time        *
    *                      requester which, in the case of this    *
    *                      client, resulted in an ABENDS0C7 in a   *
    *                      TSO process.                            *

    * IMPLEMENTATION:    * Ensure that all product elements affec-*

    *                    * After installing the fix for this APAR *
    *                      it will be necessary to reexecute the  *
    *                      HourGlass customization job. One or    *
    *                      more elements replaced by this fix are *
    *                      modified by the HourGlass customization*

    *                    * Due to the replacement of the AGGFRONT *
    *                      module, it will be necessary to stop   *
    *                      and restart the HourGlass product, via *
    *                      an AGGOFF/AGGON command sequence, to   *
    *                      fully implement this fix.              *
    *                                                             *
