  * PROBLEM DESCRIPTION: No automatic resync is done for a UOW   *
  *                      that is shunted after a timeout on an   *

  ****************************************************************
  An EXEC CICS START with the PROTECT option is function shipped
  from a CICS region to an IMS region over an LU61 link. An
  RTIMOUT value has been set for the CICS profile DFHCICSF which
  is used for function shipping. A timeout occurs during Syncpoint
  of the START (Syncpoint takes place because of the PROTECT
  option). Message DFHAC2231 reports transaction CSMI has abended
  ASP1 and that the unit of work is shunted until contact is
  restored. This is followed by DFHRM0106. The unit of work can
  only be recovered by using CEMT to Release and then Acquire the
  IMS session involved in the START.

Problem conclusion

• DFHZIS1 has been altered to check if an ABENDAZCT has occurred
  for an IMS link and if so, a CLSDST and SIMLOGON is queued for
  the link.
