Error description

  • No AUTORESETTIME=IMMEDIATE facility for CICS TS V3 R1.
    

Local fix

  • Do CEMT PERFORM RESET as quickly as possible following the
    z/os sytem clock time change.

    ****************************************************************
    On CICS Transaction Server V3 R2 or higher, PTFs were
    issued which shipped a new option of IMMEDIATE to be coded
    against the AUTORESETTIME SIT parameter.  This new parameter
    was part of the solution to a timing problem that existed at the
    aforementioned releases but not this release ( CICS TS V3R1 ).
    
    However, AUTORESETTIME=IMMEDIATE ensures that CICS and MVS
    System clocks are automatically coordinated at CICS task attach
    and has advantages over existing mechanisms.  This apar
    makes available,  the AUTORESETTIME=IMMEDIATE function to
    users of CICS V3 R1.
    

Problem conclusion

  • CICS task attach logic has been amended such that if a new
    AUTORESETTIME parameter of IMMEDIATE is coded then the CICS
    internal clock ( in CSATODP ) will get reset immediately when
    DFHAPIN detects a mismatch between the MVS and CSATODP times.
    
    The following documentation changes will be made:
    
    The CICS Transaction Server for z/OS Version 3 Release 1 System
    Definition Guide (SC34-6428-08) will be updated, the
    description for AUTORESETTIME will have an additional option
    of IMMEDIATE added and will now read as follows:
                                                                   .
    AUTORESETTIME
     The AUTORESETTIME parameter specifies the action CICS should
     take for automatic time changes.
     AUTORESETTIME= IMMEDIATE|NO|YES
                              --
       Valid values are as follows:
       IMMEDIATE
            CICS will issue a PERFORM RESET command to
            synchronize the CICS time-of-day with the system
            time-of-day if, at the next task attach, the CICS
            time-of-day differs from the system time-of-day.
    
       NO   CICS issues message DFHAP1500 to indicate that a CEMT
       --   PERFORM RESET command is required to synchronize the
            CICS time-of-day with the system time-of-day.
                                                                   .
       YES  CICS issues a PERFORM RESET command to synchronize
            the CICS time-of-day with the system time-of-day
            if, at the next local midnight, the CICS time-of-day
            differs from the system time-of-day by more than
            30 minutes; for example, setting clocks forward or
            back to adjust for summer and winter time.
                                                                   .
    The CICS Transaction Server for z/OS Version 3 Release 1, Data
    Areas manual (GC34-6902-03 ) will be updated, as follows:
    
    The CSA will have 2 new fields added to byte CSAICIND thus:
    
    .... 1... CSAICIMM      IMMEDIATE specified on AUTORESETTIME
    .... .1.. CSAICRIP      Reset in progress
    
    
    Dsect TCADY ( the System TCA ) will have a new field added to
    byte TCAAPFLG thus:
    
    .... 1... TCATSUSP      DFHAPIN suspend
    
    
    Dsect SIT ( System Initialization Table ) will have a new field
    added to byte SITMISC thus:
    
    ..1. .... SITICARI      AUTORESETTIME=IMMEDIATE
