Managing Connections

Net.Data provides a component called Live Connection to manage database and Java virtual machine connections. Live Connection maintains persistent connections to improve performance. Some Net.Data actions require a large start-up time. For example, before a database query can be issued, the process must identify itself to the DBMS and connect to the database. This is often a significant portion of the processing time needed for Net.Data macros that access a database. Another example of an expensive start up is a Java virtual machine that is needed to run Java applications (but not Java applets). Because of the way CGI programs operate, these start-up costs are paid on every request to the Web server. Net.Data provides Live Connection on the OS/2, Windows NT, and UNIX operating systems to maintain persistent connections.
