Problem summary

• ****************************************************************
  USERS AFFECTED:
  Problem affects users of:
  
  	- IBM MQ MFT Agent and Database logger
  	
  who have upgraded the JRE to 1.8
  
  
  Platforms affected:
  z/OS
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  A IBM MQ MFT Resource Monitor was created on z/OS after an
  upgrade to JRE 1.8. This upgrade has caused an erroneous
  behaviour where the Resource Monitor creation publication
  message would be encoded with two different code pages. The
  first part of the data was in UTF-8, but the second part was in
  IBM-1047 code page. While generating the Monitor Create
  publication, the monitor request XML which was in IBM-1047 code
  page was converted as String with UTF-8 encoding. This has
  caused the publication to get corrupted and cause a failure in
  the MFT logger when persisting the publication to a database,
  with the following exception:
  
  
  [26/09/2018 16:24:23:209 BST] 00000001 Logger    W  BFGDB0003E:
  A problem occurred with the database. The database driver
  reported the following details: SQL State [FFFFF], Error Code
  [-1000000], Message [[jcc][50045][12113][4.22.37]
  [DB2/T2zOS][JDBC/SQLJ]convertCharstoBytesInBuffer: Got unknown
  character exception for encoding Cp285 ERRORCODE=-1000000,
  SQLSTATE=FFFFF]
  

Problem conclusion

• The IBM MQ MFT Agent  and Logger have been updated to use the
  correct encoding as shown below:
  
   * on z/OS - IBM-1047
   * on distributed - UTF-8
