IT35365: The browse cursor advances when an AMS-enabled application receives MQRC_TRUNCATED_MSG_FAILED

APAR status

• Closed as program error.

Error description

• When MQRC_TRUNCATED_MSG_FAILED (2080) is returned to an
  application which is browsing an AMS-protected queue, the browse
  cursor is incorrectly advanced to the next message, preventing
  the application from retrying the failed browse of this message
  with a larger buffer.
  

Local fix

• Ensure that the buffer used by the application to browse the
  queue is large
  enough for the messages on the queue.
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users of MQ's Advanced Message Security component who are
  browsing messages on AMS-protected queues.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  The MQGET failed so the browse cursor should not have moved, but
  an error in MQ meant that it did, so when the application
  increased the buffer size and reissued MQGET with
  MQGMO_BROWSE_NEXT it incorrectly got the next message on the
  queue instead of the same message.  The browse effectively
  skipped the message that had been truncated.
  

Problem conclusion

• The error has been fixed.
