IT25687: MQINPUT NODE WITH RESET BROWSE TIMEOUT DOES NOT BROWSE THE MESSAGES CORRECTLY FOR THE FIRST TIME AFTER FLOW START.

APAR status

• Closed as program error.

Error description

• The customer has configured an MQInput node with 'Browse Only'
  set and 'Reset browse timeout' set to a small positive value.
  The intention here is to ensure that in the event of a
  downstream exception that the same message is browsed
  repeatedly. This all works as expected *until* they restart the
  flow. In v10, instead of browsing the first message repeatedly,
  MQGMO_BROWSE_FIRST, (until the exception has been fixed), each
  message in turn is browsed before then returning to the first
  message and browsing it repeatedly.
  

Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  All users of IBM Integration Bus V10 and IBM App Connect
  Enterprise V11 using MQInput node to browse MQ messages.
  
  
  Platforms affected:
  z/OS, MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  The user has configured an MQInput node with 'Browse Only'
  option and has 'Reset browse timeout' set to a small positive
  value.  The intention here is to ensure that the first message
  is browsed repeatedly till its removed. This all works as
  expected until they restart the flow. After restart, instead of
  browsing the first message repeatedly, each message in turn is
  browsed before then returning to the first message and browsing
  it repeatedly.
  

Problem conclusion

• The MQInput node is fixed to browse the messages correctly,
  based on  browse timeout value, after the flow restart.
