PK14233: INVALID CONVERSION FROM EBCDIC TO ASCII WHEN CICS TS 3.1 USES CLINTCP=819 AND SRVERCP=273.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Sending the input after the question mark back as data tothe
  web browser is changed from the original character string.
  the DFHCNV is using CLINTCP=819 and SRVERCP=273.,
  the initial ascii string was not converted to "273" code plate.
  It appears to be using CLINTCP=819 and ,SRVERCP=037,

  ****************************************************************
  An HTTP request is received into CICS using CICS WEB support.
  The querystring in the HTTP headers contains some national
  characters, in this case German. When the data is converted from
  ASCII into EBCDIC the server codepage used is 037 and not the
  273 as compiled into the customer's DFHCNV table for DFHWBHH.
  The DFHCNV table is no longer used for this conversion. The z/OS
  conversion routines are called to do the conversion with the
  fixed codepages source=819 and target=037. The effect of this is
  that the application receives the wrong data in its commarea.
  The same problem could be seen when using an
  EXEC CICS WEB EXTRACT QUERYSTRING.
  The target codepage should be picked up from the customer's
  LOCALCCSID SIT parameter.
  

Problem conclusion

• DFHWBSR routine wbrq_inbound_convert_headers has been changed to
  set the target codepage to the customer's LOCALCCSID setting.
  
  The CICS Transaction Server for z/OS Migration Guide v3r1
  (GC34-6425-02) has been changed on page 74. At the end of
  the first bullet which starts:
  "The code page conversion table (DFHCNV) is no longer required"
  the following has been added:
  To convert inbound HTTP header or forms data into a codepage
  other than 037, you must use the LOCALCCSID SIT parameter.
  You can set this to any codepage that is compatible with
  CCSID ISO-8859-1 (codepage 819).
  The CICS Transaction Server for z/OS
  Migration from CICS TS for z/OS 2.2 v3r1
  (GC34-6424-02) has been changed on page 112. At the end of
  the first bullet which starts:
  "The code page conversion table (DFHCNV) is no longer required"
  the following has been added:
  To convert inbound HTTP header or forms data into a codepage
  other than 037, you must use the LOCALCCSID SIT parameter.
  You can set this to any codepage that is compatible with
  CCSID ISO-8859-1 (codepage 819).
  The CICS Transaction Server for z/OS
  Migration from CICS TS for OS/390 1.3 v3r1

  the first bullet which starts:

  the following has been added:
