IT08484: MQRC_CONNECTION_BROKEN ERROR (MQRC 2009) WHEN CONNECTING FROM MQ V8 CLIENT TO MQ 75 QUEUE MANAGER.

APAR status

• Closed as program error.

Error description

• MQ V8.0 Managed .NET client application fails to connect to a MQ
  v7.5 queue manager and reports MQRC_CONNECTION_BROKEN (mqrc
  2009), if it sets user ID and password.
  

Local fix

• As a work around, MQC.USER_ID_PROPERTY and MQC.PASSWORD_PROPERTY
  properties can be removed to turn off password encryption. This
  will make MQ client to send the Windows logged in user id to
  queue manager for authorization. [This needs creating a user
  with the same name as the logged in user and then granting it
  authority to connect, put and get on the QM].
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users using MQ version 8 Managed .NET client application that
  sets user ID/password and connects to a MQ v7.5 queue manager.
  
  
  Platforms affected:
  Windows
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  An MQ version 8.0 Managed .NET client application failed to
  connect to a MQ v7.5 queue manager if the application set user
  ID and password parameters for the connection.
  
  In MQ v8, the client sends a secured password to a version 8
  queue manager during connection. However, a version 7.5 queue
  manager does not understand the secured password structure. The
  version 8 client did not correctly account for this when
  communicating with a version 7.5 or earlier queue manager and
  sent an incorrect password structure. In response to this, the
  queue manager safely closed the connection and application
  reports an error with reason code 2009.
  

Problem conclusion

• The problem is resolved by correctly checking the queue manager
  level and only sending the secured password structure if the
  queue manager is at version 8.
