Error description
Informix Dynamic Server allows for startup of multiple listener threads on a single dbserver port through adding a "-<number>" flag to the server name in the onconfig file's DBSERVERNAME and DBSERVERALIASES parameters. For example: DBSERVERALIASES informix1-2,informix2-2,informix3 In this example, 2 listener threads would be started on the informix1 and informix2 dbserver aliases, while only a single listener thread would be started on the informix3 alias. Connection Manager does not currently support this configuration. This can result in messages in the Connection Manager log indicating registration issues such as "<CM name> is already registered" upon Connection Manager startup. Alternately, an onstat -g cmsm can show multiple clusters that include a cluster named 'main' associated with the CM, when no 'main' cluster is defined in the Connection Manager configuration. It appears that when multiple listener threads are started on the database server, Connection Manager will add a cluster for each listener thread, even if those additional clusters are not defined in the configuration. However, this may cause some stability issues with the connections to the server under heavy load.
Local fix
The current workaround for this limitation is to start up only a single listener thread on each database server port.
