--配置
--1.主体服务器一台（包含主体数据库)、镜像服务器一台（包含镜像数据库）、见证服务器一台(可选，监控，故障自动转移)
--2.主体数据库：提供客户端应用程序的连接，查询，更新，执行相关事务等，主体数据库要求使用完全恢复模式。
--3.镜像数据库：持续同步来自主体数据库的事务，镜像数据库不允许任何的连接存在，但可以对其创建数据库快照来作为只读数据库，实现用户的相关查询操作。
--4.见证服务器：可选的配置，用于高可用性操作模式，通过见证服务器自动侦测故障，实现角色切换和故障转移。一个见证服务器可以为多组镜像提供服务。
--5.角色的转换：主体数据库与镜像数据库互为伙伴，当见证服务器侦测到主体服务器故障时，在高可用性模式下，实现故障自动转移后，会自动将主体服务器切换为镜像服务器角色，即角色发生了互换。
--6.确保主体服务器和镜像服务器使用相同的版本，见证服务器可以使用相对应的任意版本的SQL server。
--7.主体服务器的主体数据库设置为 FULL恢复模式。
--步骤以及常见问题
--1.主机192.168.2.152 镜像192.168.2.153
--2.用于实现镜像的数据库为Performance
--3.服务器d:mirror为共享文件夹，其中涉及的文件都放在该文件夹中
--常见1418ERROR—》 开启RemoteDacEnabled、修改hosts文件、修改计算机DNS、telnet测试、修改xpstar.dll、xplog70.dll权限
--使用管理-SQL SERVER日志来诊断具体问题
