Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICS users                               *
  ****************************************************************
  * PROBLEM DESCRIPTION: A non CICS client sends in a global     *
  *                      transaction identifier (XID) containing *
  *                      invalid data with a length exceeding    *
  *                      the available storage.                  *
  ****************************************************************
  * RECOMMENDATION: Correct the client so that it sends in a     *
  *                 global transaction identifier that conforms  *
  *                 to the standard architecture for such items  *
  ****************************************************************
  Module DFHEIUOW may cause a storage violation when a non-CICS
  JTA client sends an xOpen global transaction identifier that
  does not conform to the architected standard.
  

Problem conclusion

• Code has been added to DFHEIOUW to restrict the amount of data
  that can be returned on an EXEC CICS INQUIRE UOWLINK where the
  XID parameter is specified.
