PK10557: ABENDAKEB ABENDS0E0 ABEND0E0 ALET EYUNX0019E COSH DATATABLE DFHDTRE DFHDTRM SHUTDOWN

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When recycling CPSM's CMAS, the customer goes through the
  routine of issuing the COSH transaction in each of the LMAS's
  connected to the CMAS, then brings down the CMAS and ESSS. After
  the CMAS comes back up, they run COLM in each of the LMAS's so
  that they will reconnect.
  After EYUXL0016I lmasname  LMAS shutdown complete message is
  issued, another EYU message is seen in the log, indicating
  that an EXTRACT EXIT failure occurred:
  EYUNX0019E NOAPPLID EXTRACT Exit EYU9NXSD failed, EIBRCODE=
  800200
  Note that the lmasname has NOAPPLID for a name, CPSM has
  terminated in the LMAS
  __
  When issuing the EYUNX0019E message EYU9XESM compresses the
  message for EYU9NXSM, but in the process an overlay occurs,
  causing corruption in datatable control blocks.
  

Local fix

• Only enter COSH one time per LMAS.  If the transaction is
  entered two times, the overlay occurs.

  * PROBLEM DESCRIPTION: A storage overlay may result when a MAS *

  *                      This message can be issued if the COSH  *
  *                      transaction is run in a MAS when the    *
  *                      MAS is already disconnected from        *

  *                      The error that occurs after the overlay *
  *                      depends on the storage that is updated. *
  *                      In the reported case, the CICS Data     *
  *                      Tables Data Space anchor was changed.   *
  *                      This lead to message DFHFC0001          *
  *                      reporting a 0E0 (AKEB) abend at offset  *
  *                      X'FFFF' in module DFHFCDTS when a       *

  *                      Other possible errors include storage   *

  ****************************************************************
  * RECOMMENDATION: After applying the PTF that resolves this    *
  *                 APAR, all CMASes and MASes must be recycled  *
  *                 to pick up the new code.  Note that the      *
  *                 restarts do not need to be done at the same  *
  *                 time.                                        *
  ****************************************************************
  EYU9XEMS is the CICSPlex SM Environment Services Message
  Services program. It is typically invoked by other CICSPlex SM
  routines when the normal CICSPlex SM message service is not
  available.
  
  EYU9XEMS will compress a message if an insert passed to EYU9XEMS
  is smaller than the length of the insert defined in the messages
  skeleton.
  
  If the short insert is the last part of the message, then a
  logic error causes an invalid length to be used for the message
  compression, causing up to 256 bytes to be moved to the left.
  Such a move will shift data beyond the end of the EYU9XEMS
  dynamic storage area.
  

Problem conclusion

• The short insert compression logic in EYU9XEMS has been changed
  so that the invalid move is not performed.
  
  EYU9NXTM has been changed to pass a full length EIBRCODE insert
  to EYU9XEMS when it issues message EYUNX0019E.
