IT06165: RESEQUENCE NODE IN IBM INTEGRATION BUS TO INCLUDE A RETRY MECHANISM THAT SENDS MESSAGES TO THE FAILURE TERMINAL

IBM Integration Toolkit version 9.0 Fix Pack 6

APAR status

• Closed as program error.

Error description

• This APAR adds a retry mechanism to the Resequence node in IBM
  Integration Bus of 'failure'. With this new retry mechanism
  enabled, if a message fails to propagate to the 'out' terminal
  and the 'catch' terminal, the message is sent to the 'failure'
  terminal. Subsequent messages in the sequence are not
  propagated until that message is received again and propagated.

Problem summary

• ****************************************************************
  USERS AFFECTED:
  All users of IBM Integration Bus v9.0 that use a Resequence
  node.
  
  
  Platforms affected:
  MultiPlatform, z/OS
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  If the Resequence node fails to propagate a message to the 'out'
  and the 'catch' terminal, the only retry mechanism it has is to
  try the 'out' terminals again. This effectively means a failing
  sequence of messages will be held in the node until the problem
  downstream is fixed and the Resequence node will keep retrying
  indefinitely.
  
  There are a number of resource name changes between WebSphere
  Message Broker and IBM Integration Bus Version 9.0. For details

Problem conclusion

• The product adds a retry mechanism of 'failure' to the
  Resequence node. With this new retry mechanism enabled, if a
  message fails to propagate to the 'out' terminal and the 'catch'
  terminal, the message is sent to the 'failure' terminal.
  Subsequent messages in the sequence are not propagated until a
  message with the same sequence number as the failing message is
  received again and propagated.
