Error description

  • The 'port' and 'host' fields of a .bindings file created by a
    file system JNDI initial context may get out of sync with the
    'connection list' if the file was created pre v7.0.1.
    
    If a 'connection list' is modified by a V7.0.1 client, the
    'connection list' value will be saved into JNDI, but the 'host'
    and 'port' fields will not be updated in the .bindings file.
    This means that an older client looking up the connection
    factory will still read the unmodified 'host' and 'port fields.
    

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    This issue affects users who modify their file system Java
    Message Service (JMS) initial context using a v7.0.1 client and
    use the same initial context with clients at a lower level (v6,
    v7.0.0)
    
    Platforms affected:
    All Distributed (iSeries, all Unix and Windows) +Java
    ****************************************************************
    PROBLEM SUMMARY:
    The connectionNameList property on an MQConnectionFactory was
    introduced at v7.0.1.0 for use with the client reconnection
    capabilities.  Clients at earlier versions of the product (v6.x,
    v7.0.0.x) use the host and port fields to specify a single host
    to connect to, rather than a list of them.  When the
    connectionNameList was updated by a v7.0.1.0 client, the host
    and port fields were not being updated and so earlier clients
    would not have access to the modified connection details.
    

Problem conclusion

  • In order to fix this issue, when the connectionNameList is
    updated, the first entry in the list is copied to the host and
    port fields.
    
    Please be aware that if an earlier client (v6.x or v7.0.0.x)
    subsequently updates any of the values for the connection
    factory, all entries in the connectionNameList will be
    overwritten with the single new host/port value.
