脚本分享：别人家的镜像自动化部署

脚本1：

实例名：
主服务器：X
镜像服务器：Y

步骤：
1. 在主服务器和镜像服务器之间创建链接服务器，配置为使用RPC（Remote procedure call）调用，为了执行SP。
例如：lnk_X_Y_mirroring（链接服务器名）
2. 在主服务器上创建以下SP。
3. 根据需要使用作业每30分钟或1小时调用SP（usp_Mirroring_Configuration）。
4. 一旦一个新数据库创建，镜像会通过作业的执行被部署。
5. 将触发“Mirroring Configuration”为名的告警，内容为“Mirroring Configured for db_55555 and safety level is OFF”

DESCRIPTION: Automatic Mirroring_Configuration for new databases
AUTHOR: Vasan
DATE WRITTEN: 17 MARCH 2015
Automatic Mirroring configuration for newly created user databases:
-------------------------------------------------------------------
Instance names:
---------------
Principle server : X
Mirroring Server : Y
Steps to follow:
1. Create link server between principle server and mirror server with RPC (Remote procedure call) set as true in order to execute the procedure.
Eg : lnk_X_Y_mirroring (Link server name)
2. Create below stored procedure in to principle server.
3. Schedule this Stored procedure (usp_Mirroring_Configuration) with 30mins/1hr interval via job
4. Once the new database created in server mirroring will be configure.
5. Alert will be trigger with the subject anme of Mirroring Configuration
Mail contect:“Mirroring Configured for db_55555 and safety level is OFF”

脚本2：

准备步骤：
1. 安装和一个辅助SQL Server实例（版本、补丁和LICENSE类型跟主服务器实例一样）。
2. SQL Server连接启用TCP/IP协议。
3. 为备份和恢复操作配置网络共享，类似\\dfsroot\sqlbackup
4. 允许使用xp_cmdshell扩展存储过程。

仅通过一个触发器访问执行所有的操作是不行的。这个方法包含四个组件：1个事件接收器表，1个工作负载存储过程，1个DDL触发器和1个以一定间隔执行之前提到的存储过程的SQL Server代理作业。

步骤1：创建1个事件接收器表
该表将会保存CREATE数据库动作发生时的名字和SQL事件。事件类型不重要，我们只对数据库名感兴趣。

USE [master]
GO
/****** Object: Table [dbo].[new_db_table] Script Date: 05/19/2008 15:26:56 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[new_db_table](
[name] [nvarchar](100) NULL,
[event] [nvarchar](100) NULL
) ON [PRIMARY]

步骤2：创建自动化存储过程
这是主要的脚本，用于检查动作表，执行备份初始化。在SQL Server 2005，对于附加数据库动作是没有数据库事件的，即便事实上它是一个CREATE_DATABASE事件。在SQL Server 2008解决了，导致触发器对于ATTACH和CREATE动作，在动作表都添加一个条目。

USE [master]

insert into #userdbs select name from new_db_table

while @@fetch_status = 0
begin

exec (@mirrorsql)
–Enable the mirroring session on the Witness server:

exec (@mirrorsql)
–cleanup
delete from new_db_table where name = @dbname
set @cmd = ‘del ‘ + @bupath + ‘\’ + @dbname + ‘.bak’
exec xp_cmdshell @cmd
set @cmd = ‘del ‘ + @bupath + ‘\’ + @dbname + ‘_log.bak’
exec xp_cmdshell @cmd
fetch cdb into @dbname
end
close cdb
deallocate cdb
drop table #userdbs
end
end

步骤3：创建触发器
当匹配CREATE_DATABASE的事件发生时，它将触发，将数据库名写入事件接收器表。

/****** Object: DdlTrigger [trg_MirrorDDL] Script Date: 05/19/2008 15:31:55 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TRIGGER [trg_MirrorDDL]
ON ALL SERVER
FOR CREATE_DATABASE
AS
BEGIN
SET NOCOUNT ON;
DECLARE @data XML;
DECLARE @eventType sysname;
DECLARE @dbname varchar(100);
DECLARE @mirrorsql varchar(500);
SET @data = EVENTDATA();
SET @eventType = @data.value(‘(/EVENT_INSTANCE/EventType)[1]’, ‘sysname’);
SET @dbname = @data.value(‘(/EVENT_INSTANCE/ DatabaseName)[1]’, ‘sysname’);
–Add to new_db_table
Insert new_db_table(name,event) select @dbname,@eventType where not exists (select * from new_db_table where name = @dbname);
END
GO
SET ANSI_NULLS OFF
GO
SET QUOTED_IDENTIFIER OFF
GO
ENABLE TRIGGER [trg_MirrorDDL] ON ALL SERVER

步骤4：创建SQL Server代理作业
这个作业主要的目的是监控事件接收器表的新增条目。我原本想在事件接收器表上用一个触发器，但是你可能不想自动化，而是想通过作业来按需调度存储过程的执行可能会更好。

USE [msdb]
GO
/****** Object: Job [Mirroring Agent] Script Date: 05/19/2008 15:32:54 ******/

IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback
COMMIT TRANSACTION
GOTO EndSave
QuitWithRollback:
IF (@@TRANCOUNT > 0) ROLLBACK TRANSACTION
EndSave:

后记：
这两个脚本都是将数据直接备份到远程UNC路径。笔者之前在Bash下写过镜像自动化部署，日志传送自动化部署、检查和切换的脚本，数据传输用的winscp.exe，思路也就是把这些核心SQL封装调用。
