00314: Machine Check(s) Occurred

FILE              TSO System Activity
SAS FILE NAME     DETAIL.TSOTSO01
SOURCE LOCATION   sharedprefix.MICS.SOURCE(DYTSOEXC)

SEVERITY          Critical      (SEVERITY='C')
MANAGEMENT AREA   Performance   (MGMTAREA='PERFORMANCE')

PURPOSE      Indicates that machine failures have occurred.

RATIONALE    The health of the system hardware is an obvious
             concern from a reliability/availability
             perspective.

DEFINITION   This exception is noted when any of the
             following data elements are found with a nonzero
             value:

             TSOXSRMY - Intvls When Sys Recovery Machine
                        Checks
             TSOXIPMY - Intvls When Instruction Process
                        Machine Checks
             TSOXSMCY - Intvls When System Machine Checks
             TSOXIPRY - Intvls When Bad PSW or Reg Machine
                        Check
             TSOXTODY - Intvls When TOD Clock Machine Checks
             TSOXCTMY - Intvls When CPU Timer Machine Checks
             TSOXCCMY - Intvls When Clock Comparator Mach
                        Checks

             See Appendix B for more information on this
             data element.
