MaxConnect for Multiple Connections (UNIX)

IBM Informix MaxConnect is a networking product for Informix database server environments on UNIX. Use MaxConnect to manage large numbers (from several hundred to tens of thousands) of client/server connections.

MaxConnect is best for OLTP data transfers and not recommended for large multimedia data transfers. MaxConnect provides the following performance advantages for medium to large OLTP configurations:

• Reduces CPU requirements on the database server by reducing the number of physical connections.

  MaxConnect multiplexes connections so that the ratio of client connections to database connections can be 100:1 or higher.

• Improves end-user response time by increasing system scalability to many thousands of connections
• Reduces operating-system overhead by aggregating multiple small packets into one transfer operation

To obtain maximum performance benefit, install MaxConnect on either a dedicated computer to which Informix clients connect or on the client application server. Either of these configurations offloads the CPU requirements of handling a large number of connections from the database server computer.

To monitor MaxConnect, use the onstat -g imc command on the database server computer and use the imcadmin command on the computer where MaxConnect is located.
