SQL Server Always On failover cluster instances use Windows Server Failover Clustering (WSFC) to provide local high availability. A failover cluster instance (FCI) is redundant at the server-instance level. An FCI is a single instance of SQL Server that is installed ac...
故障转移群集(Failover Cluster Instances)和AlwaysOn是SQL Server中两种不同的高可用性解决方案。它们在实现高可用性的方式上有一些显著的区别: 故障转移群集(Failover Cluster Instances): 故障转移群集是一种基于 Windows Server 故障转移群集技术的解决方案,它使用共享存储并在主节点和辅助节点之间进行故障转移。 故障...
--- net.exe stop Cluster_Name(实为Service name) 成功关闭后172.XXX.XXX.115无法Ping 通 Step6:在单一节点上使用强制仲裁,藉以启动WSFC群集 --- net.exestart Cluster_Name/forcequorum 成功启动后Cluster IP 可以Ping 通;Listener IP 无法Ping 通 通过FailOver Cluster Manger 查看节点和AG的状态如下: 下图...
As part of the SQL Server AlwaysOn offering, AlwaysOn Failover Cluster Instances leverages Windows Server Failover Clustering (WSFC) functionality to provide local high availability through redundancy at the server-instance level—a failover cluster instance (FCI). An FCI is a single instance of ...

In an SQL Server cluster environment, two different kinds of clustering are supported; AlwaysOn Failover Cluster Instances (FCI) and AlwaysOn Availability Groups (AAGs). An SQL AlwaysOn failover cluster instance provides high availability and disaster recovery at the SQL Server level. AlwaysOn ...
A collection of cluster resources managed as a single cluster object to provide specific functionality. For SQL Server, a role will be either an Always On availability group (AG) or Always On failover cluster instance (FCI). A role contains all of the cluster resourc...
前面几篇文章都已经详细介绍了SQL Server Failover +AlwaysOn 的配置,今天我们主要介绍SQL Server Failover Cluster+AlwaysOn下 增加数据库到可用性组 我们首先需要创建一个数据库及表 数据库名称 HAGroupDB2 创建表 给表插入数据 我们把这个数据库增加到高可用性组中;当前新建的数据库没有同步 ...
