Configuration parameters related to connectivity

Some of the configuration parameters in the onconfig file specify information related to connectivity.

When you restart the database server, the restart procedure uses the values that you set in these configuration parameters.

The following configuration parameters are related to connectivity:
  • DBSERVERNAME
  • DBSERVERALIASES
  • LIMITNUMSESSIONS
  • NETTYPE
  • NS_CACHE
  • NUMFDSERVER
  • HA_ALIAS
UNIX: When you configure connectivity, also consider setting the LISTEN_TIMEOUT and MAX_INCOMPLETE_CONNECTIONS configuration parameters. These parameters can reduce the risk of a hostile denial-of-service (DOS) attack by making it more difficult to overwhelm the Listener VP that handles connections. For more information, see the IBM® Informix Security Guide.
