Oracle RAC Load Balancing allows connections initiated from clients to be effectively allocated to instances with low listener load. There are two methods to achieve load balancing on the client. One is to configure the load_balan

To perform stress testing, the middleware uses WebLogic 816, the database version is 11.1.0.6 RAC, and the stress test tool is LoadRunner 8.0. Test the load on individual nodes of a single instance and RAC environment. A multiple pool is configured on the WebLogic, and the concurrent equilibrium is divided into two nodes by using the

Server Load balancer is a server set composed of multiple servers in a symmetric manner. Each server is equivalent and can provide services independently without the assistance of other servers. Through a load balancing technology, requests sent from outside are evenly distributed to a server in the symmetric structure, and the server receiving the requests indep

What is LVS??? Let's start with a brief introduction to LVS (Linux Virtual Server), which is actually a cluster (Cluster) technology that uses IP load balancing technology and content-based request distribution technology. The scheduler has a good throughput rate, transfers the request evenly to the different server execution, and the scheduler automatically shields off the server's failure, thereby forming
