JR28917: MESSAGE TRUNCATED WHEN AFTER READING A CHAR(00) WITH THE MQ

APAR status

• Closed as program error.

Error description

• The MQ connector, parallel operator, is
  truncating message if it contains after
  encountering a char(00)
  

Local fix

• Use the MQ plugin instead of the MQ operator
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Information Server 8.0.1.1 on AIX
  ****************************************************************
  PROBLEM DESCRIPTION:
  The MQ connector stage truncates text messages which have 0x00
  bytes in the data. All the messages are truncated at the first
  occurrence of 0x00 in them.
  ****************************************************************
  RECOMMENDATION:
  The patch was delivered to the customer for IS 8.0.1.1.
  Information Server 8.1 includes the fix for this problem so
  upgrading to IS 8.1 when it becomes available would also be an
  option.
  ****************************************************************
  

Problem conclusion

• The implementation of the connector framework method that moves
  data from the connector to the engine was not handling data
  propely when it had 0x00 bytes in the data. The truncation was
  happening at the 0x00 boundaries.
  Also, the connector didn't handle case when the MQ queue
  manager failed to perform conversion of data - this was the
  case when the CCSID of the queue manager didn't match the CCSID
  of the retrieved message, the message was not of MQSTR type,
  the message data had 0x00 bytes. The connector was passing data
  to framework in this case using accessor method that assumes
  null termination, to data truncation was happening. The
  connector was fixed to handle this particular scenario and
  preserve 0x00 bytes by calling adequate accessor method on the
  connector framework.
  

Temporary fix
