Error description

  • If an actual CA Command is executed, the proper values for the
    LSN, DSSN, LRID and USID fields are recorded, however when the
    DBRC NOTIFY.CA command is used there is no support to provide
    a value for these fields.

Problem summary

  • ****************************************************************
    * USERS AFFECTED: All IMS V11 DBRC users that have a need      *
    *                 to set values for LSN, DSSN, LRID, & USID    *
    *                 for CA record in RECON                       *
    ****************************************************************
    * PROBLEM DESCRIPTION: Provide NOTIFY.CA command support for   *
    *                      LSN, DSSN, LRID, & USID                 *
    ****************************************************************
    * RECOMMENDATION: INSTALL CORRECTIVE SERVICE FOR APAR/PTF      *
    ****************************************************************
    There is a need to be able to set values for LSN, DSSN, LRID,
    and USID fields in change accum record to the RECON data set
    through the usage of DBRC NOTIFY.CA command.  This change will
    make CA record a more complete command instead of using zero
    values for these four fields. In addition, this change will
    include a new CMD flag in CA record whenever a CA is being
    created by a NOTIFY.CA command.
    

Problem conclusion

  • GEN:
    KEYWORDS:
    
    *** END IMS KEYWORDS ***
    Four new parameters, LSN, DSSN, LRID, and USID, have been added
    for the NOTIFY.CA command.

    The code has been changed for DBRC NOTIFY.CA LSN, DSSN, LRID,
    and USID command support.
    
    Macro DSPKWMAC, modules DSPKWTBL, DSPUCA00, DSPURT00, DSPURT30 &
    DSPURX00, along with copy files DSPCHGRC, DSPCM2RC, DSPEXTFM,
    and DSPPPQCA, have been changed.
    
    Module DSPURLB3 has been changed to display CMD flag in the
    RECON listing for a CA record that is being created by an
    external command.

       LRID   = CCCCFFFFCCCCFFFF  USID   = 2147483647
    
    
    Module DSPAPQ31 along with macro file DSPAPQCA has been changed
    to provide DBRC API support by setting apqca_EXTCM to the value
    of chgEXTCM in DSPAPQ31. Apqca_EXTCM is the X'04' bit of the
    apqca_flags byte in the DSPAPQCA block.
    
    DSPEXTFM and DSPUCA00 used to be chained using 6 bytes and now
    chained using 8 bytes with the LSN values in the last 6 bytes.
    DSPURT30 expects LSN values to be chained using 8 bytes.

    has been updated to include four new keywords to MSGDSP0144I as
    following:
    
    DSP0144I
    
    The number of PURGLIST|LSN|USID|LRID|DSSN items specified in the
    NOTIFY command is greater than the number of database data sets
    defined (as group members) in the change accumulation (CAGROUP)
    record. This is not allowed.
