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
