The main function of the Sentinel is to provide the Redis m-s (master,slaves) cluster with 1 master Survival Detection 2) cluster M-S Service monitoring 3) automatic failover, m-s role conversion and other capabilities, in one respect, improve the

The most outstanding performance of the OracleRAC cluster is high availability, which mainly includes loadbalance and failover. Through these technologies, spof does not affect the client.

Reprint: http://dufei.blog.51cto.com/382644/902026Today, customers ask about Windows Clustering, after all, the cluster technology supported by Windows SERVER2008 and Windows Server2003 are a bit different, and the following knowledge is collected for reference. The following items are from the Internet.Windows Server 2008 provides two clustering technologies: a failover cluster and a network that is responsible for balancing the cluster.

Oracle RAC also has HA (High Availiablity) and LB (LoadBalance), and its High availability is based onFailover (Failover)It means that the failure of any node in the cluster will not affect the user's use, and the user connected to the faulty node will be automatically transferred to the healthy node. In terms of user experience, this switchover is not felt. Oracle 10g RAC Failover can be divided into thre

How to Create a SQLServer2000 failover Cluster How to Create a SQL Server 2000 failover Cluster Before creating an SQL Server 2000 failover cluster, you must Configure Microsoft cluster service (MSC) and use the Cluster Administrator in Microsoft Windows NT4.0 or Windows 2000 to create at least one cluster disk resource.

Load balancing and failover 1, mission objectivesThis task is to solve the server load balancing and failover, this load balancing is to achieve a true sense of load balancing, the actual use, according to the server's various performance indicators for task allocation, in order to achieve fast response, experience high effect. Second, failover is a complement to

The failover of Oracle Data Guard was described in both previous articles, but there was no systematic explanation, so in this paper, DG's failover is described in a systematic note.
