Preface: There are two main ways to manage session in a Tomcat cluster: 1). Sticky session Indicates that requests sent from the same window will be processed by the same tomcat in the cluster. The configuration is workers.properties the XML code worker.lbcontroller.sticky_session = True in the file above The advantage of sticky sessions is that it does not bounce back and forth on different tomcat, but the

Please note that this tutorial is used for Redis3.0 (including 3.0) versions above Redis Cluster Introduction The Redis cluster is an assembly that provides data sharing between nodes across multiple Redis . The Redis cluster does not support commands that handle multiple keys, because it requires moving data between different nodes to not achieve performance li

The database used to save the computing results is an important part of the entire information system, and the technology is relatively mature. However, for all databases, apart from recording the correct processing results, there are also some challenges: how to increase the processing speed, data availability, data security, and dataset scalability. Join multiple databases to form a Database Cluster The database used to save the computing results is

Computing the number of cluster projects in Linux is the same as computing the number of startup companies in Silicon Valley. Unlike Windows NT, which has been blocked by its own closed environment, Linux has a large number of cluster systems to choose from and is suitable for different purposes and needs. However, it is not easy to determine which cluster should

To start working as a cluster, find some information to see: Tip: This article provides server cluster requirements and best practices for the network infrastructure of a Microsoft Windows 2000 or Windows Server 2003 server cluster. To make the cluster run properly, you must meet these requirements. The best practice

First, what is RHCsRHCS is the acronym for Red Hat Cluster suite, which is RHCs, a collection of cluster tools that provide high availability, high reliability, load balancing, storage sharing, and cost-effectively, combining the three clusters in a clustered system to give Web applications, database applications, etc. to provide a secure and stable operating environment.More specifically, RHCS is a fully f

Redis cluster is an official redis cluster function provided by redis.1. Why is redis Cluster implemented? 1. master-slave replication cannot achieve high availability 2. as the company develops, the number of users increases, concurrency increases, and business needs higher QPS. However, the QPS of a single machine in master-slave replication may not meet busine

Original English version, Chinese versionTony TangTranslation Arrangement In the first part, I briefly described the various factors that need to be taken into account during the design of a large J2EE system with upgrading and high reliability. This article discusses Tomcat's support for cluster, Server Load balancer, fault tolerance, session replication, and other capabilities. In this section, we will see the complete

In more and more cases, it must meet high availability standards. Is it because the cluster technology seems too advanced, hard to understand and use, and you have not made the application a new level? With Microsoft's clus
