Error description

  • DSS UIM module DFSUDUI1 parses the task identifier form DSS
    Message ADR101I which was changed in z/OS 1.13 to add a time-
    stamp before the TASKID. This caused the TASK ID to be parsed
    incorrectly producing unpredictable results in V11.

    Prior to DSS 1.3.1
    ------------------
    
    ADR101I 'taskid xxx has been assigned to command DUMP'
      IC2 captures the task ID from the DSS message and saves
      the IDS entries for the DBDSs that were on the last dump
      command that was passed to DFSMSdss.  On subsequent task
      related exit invocations, we use the taskid to identify
      the DBDSs being processed by the task.
    
    After DSS 1.3.1
    ---------------
    
    ADR101I is issued as above until the DSS server ADRXAIMR
    has quiesced for five minutes or the patch byte has been set
    for diagnostic or accounting purposes. Subsequently all
    ADR101I messages will include a time stamp immediately before
    the TASKID.
    
    This causes the code in IMS UIM DFSUDUI1 to incorrectly parse
    the time stamp instead of the TASKID and depending on what
    the value is for the timestamp the parsed result may be
    mistaken for a TASKID. This results in intermitent errors,
    incorrect output and unpredictable errors.

Problem conclusion

  • GEN:
    KEYWORDS: ZOS0201T/K
    
    *** END IMS KEYWORDS ***
    The code in DFSUDUI1 has been changed to search for the
    string 'TASKID' in the message and no longer depends on
    a constant offset within the message.
