HCL OneDB MaxConnect

HCL® OneDB® MaxConnect is a networking product for HCL OneDB database server environments on UNIX™. OneDB MaxConnect manages large numbers (from several hundred to tens of thousands) of client/server connections.

OneDB MaxConnect multiplexes connections so that the ratio of client connections to database connections can be 200:1 or higher. OneDB MaxConnect increases system scalability to many thousands of connections and saves system resources, reducing response times and processor requirements. OneDB MaxConnect is best for OLTP data transfers and should not be used for large multimedia data transfers.

Install OneDB MaxConnect separately from your HCL OneDB database server and client applications. For maximum performance benefit, install OneDB MaxConnect either on a separate computer to which HCL OneDB clients connect or on the client application server. You can install OneDB MaxConnect in the following configurations:
  • On a dedicated server to which HCL OneDB clients connect
  • On the client application server
  • On the database server computer
Two protocols for multiplexing connections, ontliimc and onsocimc, are available for OneDB MaxConnect users. You can use the ontliimc and onsocimc protocols in the following two configurations:
  • To connect OneDB MaxConnect to the database server.

    In this configuration, the client connections are multiplexed and use packet aggregation.

  • To connect the client applications directly to the database server without going through OneDB MaxConnect.

    In this configuration, the client does not get the benefits of connection multiplexing or packet aggregation. Choose this configuration when the client application is transferring simple- or smart-large-object data, because a direct connection to the database server is best.

For more information about how to configure OneDB MaxConnect and monitor it with the onstat -g imc and imcadmin commands, see the HCL OneDB MaxConnect User's Guide.
Important: OneDB MaxConnect and the HCL OneDB MaxConnect User's Guide ship separately from the HCL OneDB database server.
