About Live Connection

Live Connection can dramatically improve performance by eliminating start-up overhead. The savings come from continuously running one or more processes that perform the start up functions. These processes then wait to service requests. You can run Live Connection if you use Net.Data as a CGI or FastCGI program, or as a Web server API plug-in.

Live Connection consists of Connection Manager and cliettes. Cliettes are processes that the Connection Manager starts, and stay active while the server is running. Cliettes process data and communicate with Net.Data language environments that you specify in the initialization file with the keyword CLIETTE. Each type of cliette handles a specific language environment function, such as the DB2 cliette, which connects to the DB2 database and sets up operations to perform SQL calls before any Net.Data macros are processed by Net.Data. The executable file is named in the Live Connection configuration file, dtwcm.cnf. Figure 25 shows the interaction between Live Connection, the macro, and the language environments.
