This article is the fourth in the GC expert series. In the first understanding of Java garbage Collection, we learned several different GC algorithm processing processes, the way GC works, the difference between the new generation and the old age. So, you should have known about the 5 GC types in JDK 7, and the performance impact of each GC.The second monitoring of Java garbage collection describes how the JVM runs the GC in real-world scenarios, how

This article is reproduced from IBM developerLet's start by introducing why we want to connect Apache with Tomcat. In fact, Tomcat itself has provided the HTTP service, the default port of the service is 8080, after the installation of Tomcat through the 8080 port can be directly used by

So. 700m memory corresponds to MaxClients 175.SummarizeA robust service configuration should at least reduce the time it takes to go down when the service is overloaded and successfully respond to requests within a reasonable range. For Java-based Web services. You must check that your service is able to respond to requests for stability in the STW time caused by the full GC.In order to respond to more user requests and respond to DDoS attacks, without taking into acc

Most people who start to touch Web servers may be as surprised as I am with Apache and Tomcat servers (they're all developed by Apache), but they're not redundant servers, but they all have their own focus, although they can provide a Web server. Here's a brief introduction. 1. Apache is the world's number one Web ser
