Re: CGI-based Web applications and Informix connection rate limit

The accepting of new engine connections is facilitated by listener threads. The rate of making new connections will be indivual to every system depending on resources avialbble so I can't tell you a number to expect. To start multiple listener threads you'll need to use multiple ports and multiple DBSERVERNAMES (in onconfig). Then assign divide the users between the defined DBSERVERNAMES. sqlhosts -------- dbservername1 ontlitcp hostname port1dbservername2 ontlitcp hostname port1 - this can be the same onconfig -------- DBSERVERNAME dbservername1 DBSERVERALIASES dbservername2 You can verify that you have multiple listeners running by running onstat -g ath | grep listen -Bill > > In the course of load testing a CGI-based Web application, we have > noticed that Informix seems to accept new database connections at the > rate of approximately 5/second.
