【MSSQL】 SQL Server镜像自动生成脚本
作者:烨鑫 / 发布于2016/3/30/ 851
镜像的搭建非常繁琐，花了一点时间写了这个脚本，方便大家搭建镜像

执行完这个镜像脚本之后，最好在每台机器都绑定一下hosts文件，不然的话，镜像可能会不work

最后附上镜像相关脚本

--=================================
--拆除镜像

SELECT  DB_NAME([database_id]) as 'dbname',* FROM sys.[database_mirroring]
GO

ALTER DATABASE [test] SET PARTNER OFF
ALTER DATABASE [test] SET WITNESS OFF

--=================================
--恢复镜像
USE [master]
GO
ALTER DATABASE [Demo1] SET PARTNER RESUME
GO

--=================================
--挂起镜像  
USE [master]
GO
ALTER DATABASE [Demo1] SET PARTNER SUSPEND 
GO


--===================================================
--未发送的日志和未重做的日志情况
WITH tmp AS(
SELECT
DB_NAME(Database_id) AS DatabaseName,
ROW_NUMBER()OVER(PARTITION BY Database_id ORDER BY local_time DESC) AS RID,
*
FROM msdb.dbo.dbm_monitor_data
)
SELECT *  FROM tmp
WHERE RID=1

--看一下redo_queue 和send_queue



--=================================
--删除镜像
USE [master]
GO
ALTER DATABASE [Demo1] SET PARTNER OFF
GO
 
--=================================
--移除见证服务器
USE [master]
GO
ALTER DATABASE [Demo1] SET WITNESS OFF
GO
 
--=================================
--修改为高性能模式
USE [master]
GO
ALTER DATABASE [Demo1] SET PARTNER SAFETY OFF
GO
 
--=================================
--修改为高安全模式
USE [master]
GO
ALTER DATABASE [Demo1] SET PARTNER SAFETY FULL
GO
 
--=================================
--在高安全下手动转移镜像（在主服务器上）
USE [master]
GO
ALTER DATABASE [Demo1] SET PARTNER FAILOVER
GO
 
--=================================
--在高性能下手动转移镜像（在从服务器上）,此时主服务器已停止
--同样适用高安全
USE [master]
GO
ALTER DATABASE [Demo1] SET PARTNER FORCE_SERVICE_ALLOW_DATA_LOSS
GO
 
--=================================
--在镜像被挂起后恢复镜像回话
--如镜像服务器停止后又重启时，主体服务器会被挂起，使用以下SQL来恢复镜像
USE [master]
GO
ALTER DATABASE [Demo1] SET PARTNER RESUME
GO
 
--=================================
--将数据库从还原状态转化成正常模式
USE [master]
GO
RESTORE DATABASE [Demo1] WITH RECOVERY
GO
 

--=================================
--修改为高安全模式
USE [master]
GO
ALTER DATABASE [Demo1] SET PARTNER SAFETY FULL
GO


--=================================
