00313: AP/MP/Dyadic System Running in HD Mode

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 unusual machine operating mode.

RATIONALE    A multiprocessor may be run as either one system
             with two CPUs or two systems with one CPU each
             ("half-duplex" mode), but sites usually pay the
             extra cost of an MP because they intend to run
             it as a multiprocessor.  This exception assumes
             that if an MP is running with only one CPU, it
             is because the other is down.  (This is always
             true of attached processors and dyadic
             processors which do not support partitioning).

DEFINITION   This exception is noted when the data element
             TSOXCPUH (Intvls When CPU in HD Mode) is found
             with a nonzero value.  Consult the CA MICS Data
             Dictionary for more information about this data
             element.

EXCEPTION    The SAS statements identifying the exception
STATEMENTS   situation and describing the condition are
             stored in the source member named in SOURCE
             LOCATION and are described below:

************************************************************;
*
** 00313
** AP/MP/DYADIC SYSTEM RUNNING IN HD MODE
*;
IF TSOXCPUH > 0
 THEN DO;
  EXCCODE='00313'; SEVERITY='C'; MGMTAREA='PERFORMANCE';
  EXCDESC1='AP/MP/DYADIC SYSTEM RUNNING IN HD MODE';
  EXCDESC2=' ENDTS=' || PUT(ENDTS,DATETIME19.2);
  LINK HIT;
END;

THRESHOLD     None required.  You should disable this
MODIFICATION  exception for any MP that is normally run as
              two UPs.
