Error description

  • Error message AMQ9616 is reported by MQ when the CipherSpec

    SSL/TLS server.
    
    The message lists probable causes, but does not include the
    possibility that the proposed CipherSpec has been deprecated.
    

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users of MQ who attempt to use deprecated CipherSpecs and
    encounter the AMQ9616 error message
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    A number of CipherSpecs which are considered weak have been
    deprecated within MQ, and are disabled by default.
    
    If a remote MQ client or queue manager attempts to connect to a
    queue manager using a CipherSpec that has been disabled, the
    AMQ9616 message will be reported by the queue manager at the
    receiving end of the MQ channel.
    
    The contents of the AMQ9616 message did not state CipherSpec
    deprecation as a possible cause of the error condition.
    

Problem conclusion

  • The AMQ9616 error message has been updated to included
    CipherSpec deprecation as a possible cause of the error
    condition.
