APAR status

  • Closed as program error.

Error description

  • File Control exit XFCFRIN does not initialize the length field
properly when control is passed to the user code. Currently,
the user code will be passed uninitialized storage. XFCFRIN
will need to pass a null pointer if length is not specified.

Problem summary


    

  • ****************************************************************
* USERS AFFECTED: All.                                         *
****************************************************************
* PROBLEM DESCRIPTION: UEP_FC_RECORD_L may address invalid     *
*                      data when invoking XFCFRIN.             *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
UEP_FC_RECORD_L may address incorrect data when invoking the
GLUE XFCFRIN. If RECORD_LENGTH has been omitted on an EXEC CICS
WRITE or REWRITE file control command, then UEP_FC_RECORD_L will
address residual data. It is therefore not possible in the exit
to determine whether RECORD_LENGTH was omitted or not.

Additional Keywords: Global User Exit FCFR_RECORD_LENGTH_X

    



Problem conclusion


    

  • DFHFCFR has been changed. UEP_FC_RECORD_L will be set to nulls
(binary zeros) when the GLUE XFCFRIN is invoked and
RECORD_LENGTH was omitted from the file control request.
