PK53783: DATA CONVERSION CODEPAGE(-1) NOT DONE WHEN CALLING CICS TS OVER IPIC

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When an ECI call is made to CICS TS using EXCI, the protocol
  allows for the correct indication of whether data conversion is
  required. This option needs to be made available for IPIC to
  allow for migration between the protocols.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICS Users of CTG V7.1 for z/OS.         *
  ****************************************************************
  * PROBLEM DESCRIPTION: Incorrect data conversion when          *
  *                      processing an ECI call for CTG v7.1 for *
  *                      z/OS via an IPIC connection.            *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  If CTG requests conversion using the default client code page
  on an ECI call via an IPIC connection into CICS then this is
  ignored.
  

Problem conclusion

• 1. DFHISSR has been amended to check for an input CCSID of
  ISHH_DEFAULT_CONV, and if this is set to set the issb_ccsid to
  issb_default_conv.
  2. DFHMIRS has been amended to check for a CCSID of
  issb_default_conv, and if it is set to skip the call to verify
  the CCSID and convert it to an internally-acceptable manner.
  3. DFHMIRS has also been amended to check again for a CCSID of
  issb_default_conv, and if it is set to not pass an override
  CCSID to DFHCCNV when data conversion is requested. This results
  in DFHCCNV using the default client CCSID, as required.
  .
  In the CICS Transaction Server for z/OS Version 3 Release 2 CICS
  Supplementary Data Areas manual, GC34-6864, the "ISDCC ISC IP
  Domain Control Blocks" has been altered as follows:
  - The Description for ishh_ccsid has been changed to:
    "client ccsid:' ' for no conv, '-1   ' for default conv"
  - The comment above the ISHH_NO_CONV constant has been changed
    to:
    "ishh_ccsid, required for msg_type=D & conv_state=B, has
     value:
     - a 5 digit decimal IBM CCSID supported by dfhcnv or
     - blanks for no data conversion for e.g DPL commareas or
     - minus one for the default client code page (CLINTCP) to be
       used e.g. for when the input CCSID can not be determined"
  - Details of a new constant has been added after ISHH_NO_CONV as
    follows:
    "Len=5
     Type=CHARACTER
     value='-1   '
     Name="ISHH_DEFAULT_CONV"
     Description="use default code page"
  .
  The same changes have been made for the "ISMF ISC IP Message
  Formats" section of the same manual.
