PI55585: WARNING MESSAGE EKYB229W IS RECEIVED FROM THE SELECTOR. 16/04/14 PTF PECHANGE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The Selector issued warning message EKYB229W indicating that
  an unlogged time period is followed by a period for which
  archived logs exist and that it considers that (IMS) log
  archiving may have failed.  Inspection of logging conditions
  within the environment determine that no logs are problem exist
  with logging.  The problem occured in adata sharing environment.
  

Local fix

• The problem was avoided by manipulatin of the Selector start
  time avoiding the period during which the message was triggeed.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of the IMS DataPropagator Version 3    *
  *                 Release 1 asynchronous Selector component.   *
  ****************************************************************
  * PROBLEM DESCRIPTION: After applying PTF UI30480, MSGEKYB229W *
  *                      may be encountered when running the     *
  *                      Selector.  In different circumstances   *
  *                      MSGEKYB343E may also occur.             *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  After applying PTF UI30480 the message EKY229W may be received
  with accompanying messages indicating a likely problem with
  IMS logging for a subsystem being considered by the Selector.
  However, because of a programming error introduced associated
  with APAR PI30222 (PTF UI30480) this GAP in time where no
  IMS logs exist may be incorrectly flagged as being a period of
  concern.
  
  EKYB210I A PERIOD OF TIME EXISTS WHERE NO LOGS ARE AVAILABLE FOR
           SUBSYSTEM "subsystemid"
  EKYB222I THE UNLOGGED PERIOD IS BETWEEN THE IMS TIMESTAMPS
           "time stamp 1" and "time stamp 2"
  EKYB229W THE UNLOGGED TIME PERIOD DETAILED ABOVE IS FOLLOWED BY
           A PERIOD FOR WHICH ARCHIVED LOGS EXIST.
           LOG ARCHIVING MAY HAVE FAILED
  EKYB224I THE SELECTOR STOP TIME IS DETERMINED TO BE THE POINT OF
           DISCONTINUITY OF THE IMS LOG FILES
  
  Because of the above conditions being identified by the
  Selector, further processing ends and the Selector terminates.
  
  Additionally, after applying PTF UI304980 in circumstances
  where IMS logs being processed by the Selector where DBRC is
  still reporting timestamps one tenth of a second precision
  (e.g. in IMS V9 subsystem), then the message EKYB343E
  may occur, indicated an error was encountered reading IMS log
  files.  i.e. error message:
  EKYB343E ERROR OCCURED WHILE READING THE IMS LOG FILES
  

Problem conclusion

• The problem resulted because of a programming error in the
  Selector module which performs validation off the IMS logging
  environment in which it is functioning for the period of time in
  which it is interested in capturing IMS changed data from IMS
  logs.  As a result of this programming error the Selector may
  incorrectly identify a legitimate period of time when IMS is
  down as being a potential invalid gap in the IMS logs in which
  it is interested.  Selector module EKYB215X has been changed to
  avoid the Selector flagging an otherwise legitimate gap in IMS
  logging as a being a period it needs to be concerned about.
  
  In problem situation where message EKYB343E occurs this is a
  result of changes made associated with earlier PTF UI30480
  which changed Selector processing to exclusively use DBRC
  reported timestamps using microsecond precision timestamps.
  Changes are now added to Selector modules to consider the
  possibility that DBRC reported timestamps of one tenth of a
  second precision may still be encountered during Selector and
  not exclusively microsecond timestamp precision values.
  When the Selector encountered one tenth of a second DBRC
  reported timestamps prior to the changes made associated
  with this APAR, it is possible that all applicable IMS log
  records may not be written to ULR during Selector processing.
  This sets up the possible conditions where message EKYB343E may
  occur on the following Selector run because the prior Selector
  did not write all appropriate records to the ULR and record
  sequencing problems may then be identified.
