WebSphere MQ V7.0.1 for i5/OS Fix Pack 7.0.1.3
WebSphere MQ V7.0 Fix Pack 7.0.1.3

APAR status

• Closed as program error.

Error description

  applications that rely on MQSERVER to connect to a queue manager
  start to fail with reason code 2277 MQRC_CD_ERROR.
  

Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  All users of .NET using client connections from 7.0.1.1 and
  higher.
  
  Platforms affected:
  Windows
  
  ****************************************************************
  PROBLEM SUMMARY:
  A .NET application connecting with client bindings fails to
  take into account MQSERVER or MQCHLLIB/MQCHLTAB environment
  variables. For example, constructing a MQQueueManager object
  with a queue manager name will fail to connect via client
  bindings with a MQRC_CD_ERROR return code.
  
  This occurs because a change went into the .NET layer to
  distinguish between client and server connections, which forced
  a client connection to construct its own MQCD before the call
  and hence it skips the MQSERVER, MQCHLLIB/MQCHLTAB checking.
  

Problem conclusion

• The .NET layer has been modified to correctly allow the use of
  MQSERVER and MQCHLLIB/MQCHLTAB environment variables when basic
  connections are attempted (in other words, when no connection
  name or channel is identified by the application).
