Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• If a customer has a URIMAP which specifies ANALYSER(NO), CICS
  may bypass the code which reduces wrb_user_data_length to be
  less than 32K. This is after the analyzer program is called (in
  refstep wbrq_link_to_analyzer).
  However, since the customer may code a URIMAP for the incoming
  request which is defined with ANALYZER(NO) then CICS bypasses
  the call to the analyzer and wrb_user_data_length ends up as the
  incoming content-length (which is greater than 32K).

  ****************************************************************
  Using a URIMAP with ANALYZER(NO) specified, a large (>32k)
  request is received. The body of the request is copied to a
  temporary buffer to convert the data. The amount of data in the
  source buffer is a maximum of 32k, however if no ANALYZER is
  called, the length value has not been altered and would be >32k.
  In this case we would attempt to read past the 32k of data
  available and if the area is not addressable then an ABEND0C4
  will occur. Specifying ANALYZER(YES) would eliminate this
  problem.

Problem conclusion

• UK06308 UK06228 UK08975 UK09477 UK12179
  DFHWBSR has been changed in routine
  convert_user_data to pass the buffer containing the original
  data as input to the CONVERT_DATA call, unless the analyser was
  called and was passed less than 32K of data. In that case the
  analyser may have modified the data and the changes
  must be preserved by storing the data in an intermediate
  temporary buffer.
