PM83480: DFSMS SERVER RC=12 TO DBRC IMAGE COPY 2 REQUEST

Obtain the fix for this APAR.

APAR status

• Closed as program error.

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:
  REQUISITE MAINTENANCE:
  
  *** 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.
