Error description

  • Communications Server for AIX and Linux
    ---------------------------------------
    On a server participating in a Connection Network, when
    attempting to activate a session, if a Locate returns
    connection network information containing a hostname that
    when resolved has an IP address that matches an active
    link, the session activation will fail if the active link
    is configured with a different hostame even though it
    resolves to the same IP address.
    

Local fix

  • Update DNS to be consistent across the network, to use only one
    hostname to refrence this server.
    

Problem summary

  • When DNS aliases are used instead of the real hostname, a
    Connection Network link may resolve to the same IP address as an
    already active link, but because the hostnames used
    are different CommServer will not recognize this match.
    CommServer will attempt to activate a new link, and the link
    will fail to activate because it would duplicate an already
    active link.
    
    In a CommServer DLC trace, this would be seen as:
    SND>> CNCT_OUT REQ
    <<RCV CNCT_OUT RSP ERROR
    
    This behavior is incorrect.
    

Problem conclusion

  • Code has been corrected to recognize when a Connection Network
    link would duplicate an already active link, so the already
    active link will be used.
    

Temporary fix
