IC90890: MQ V7.1 OR V7.5: EBCDIC NEWLINE X'15' CONVERTED INTO ASCII X'0A' INSTEAD OF X'85' WHEN USING CONVEBCDICNEWLINE=TABLE

Fix Pack 7.1.0.4 for WebSphere MQ V7.1
WebSphere MQ V7.5 Fix Pack 7.5.0.3

APAR status

• Closed as program error.

Error description

• Messages sent by a z/OS queue manager in CCSID 1147 contains
  the EBCDIC New Line character x'15'. When an MQGET is attempted
  on that message with convert option on a windows queue manager
  in CCSID 819, the conversion of the New Line character is
  different between MQ V7.0.1 and V7.1 / V7.5.
  
  Following table summarizes the behavior seen
  
  NL char         MQ 7.0.1         MQ 7.1 / 7.5
  EBCDIC          ASCII            ASCII
  converted to     converted to
  x'15'           x'85             x'0A'
  
  On the server queue manager on Windows, ConvEBCDICNewline=TABLE
  is used.
  

Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users of MQ version 7.1 and 7.5 setting the value
  ConvEBCDICNewline=TABLE
  
  Platforms affected:
  Windows
  
  ****************************************************************
  PROBLEM SUMMARY:
  The newline character was not being converted according to the
  conversion tables although the value of ConvEBCDICNewline was
  set to TABLE on the windows queue manager. This was causing the
  new line character to be converted into a different ASCII value
  on 7.1/7.5.
  

Problem conclusion

• In the WebSphere MQ code the value of the attribute
  ConvEBCDICNewline was not read properly due to which the code
  was traversing a different path and hence the conversion was
  not taking place correctly.
  
  The fix ensures that the value of the attribute is read properly
  and the conversion of the newline character happens according to
  the values in the conversion tables.
