The specific configuration of Oracle load Balancing is described in detail in this paper. Through the client and server side of the configuration, the text of the code is more comprehensive, worthy of reference. For professional data-processing Oracle arcs, load-balancing settings are even more important. So how do yo

With the increasing of traffic and the demanding of response speed, it is very important to carry out load balancing. The company's system was initially designed to take into account the planning of load Balancing, WWW static server configured Two, because the initial project time is tight, and the traffic is not high,
