Error description

• After PM56571/UK75880 installation, selector always tries to
  read SLDS datasets beginning from the SLDS in which the "LAST"
  database update log resides.
  When a part of PRILOG got compressed by DBRC because of 24 hours
  being passed, DPROP selector failed with;
  EKYB229W THE UNLOGGED TIME PERIOD DETAILED ABOVE IS FOLLOWED BY
  A PERIOD FOR WHICH ARCHIVED LOGS EXIST. LOG ARCHIVING MAY HAVE
  FAILED
  .

Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of IMS DataPropagator Version 3        *
  *                 Release 1 asynchronous Selector component.   *
  ****************************************************************
  * PROBLEM DESCRIPTION: The Selector may issue warning message  *
  *                      MSGEKYB229W with this message being     *
  *                      preceded by MSGEKYB222I.                *
  ****************************************************************
  * RECOMMENDATION: INSTALL CORRECTIVE SERVICE FOR APAR/PTF      *
  ****************************************************************
  The IMS DataPropagator asynchronous Selector may issue warning
  message EKYB229W during processing.  This message is preceded by
  message EKYB222I.  In the particular case of the reported
  problem the situation encountered was a result of DBRC PRILOG
  compression eliminating reference to an IMS log required by the
  Selector.  In the problem situation subsequent runs of the
  Selector will "stall" indicating the same time period being
  identified via message EKYB222I unless changes are made to
  indicate to the Selector to bypass this period.
  

Problem conclusion

• The problem was a result of the Selector not adjusting it's
  leading edge processing time when no log records of interest to
  the Selector were encountered during a particular run.  In the
  reported problem situation runs of the Selector were made over
  several days without any records of interest by the Selector
  being encountered.  Eventually the Selector then encountered a
  situation where PRILOG compression had removed reference to an
  IMS log the Selector expected to be available.  Changes have
  been made to the Selector to move the leading edge processing
  time forward to an appropriate time even though no records of
  specific interest to that Selector have been encountered, thus
  avoiding problems of the type in the reported problem case.
  However, this does not mean that in all situations PRILOG
  compression will now not result in the Selector not finding an
  IMS log that it requires for processing.  The Selector must
  still run on a frequent enough schedule to not be impacted
  by DBRC log references being unavailable.
