数据库运维中盛传一个小段子，我误删除了数据库，改怎么办？有备份还原备份，没有备份就准备简历！听起来有趣但发生在谁身上，谁都笑不起来。接触了很多的客户发现90%客户的运维策略都不是很完善。本篇就分享一些常规的运维脚本，本篇没有涉及到的或不足的也请大家留言无私贡献深藏多年的脚本，谢谢！
邮件
邮件主要用来监控作业是否运行成功，如果您已经配置了类似zabbix等软件请忽略。
配置邮件服务
--SQL Server 并没有内置邮件服务器（Mail Server），它跟我们发送邮件一样，需要用户名和密码通过 SMTP（Simple Message Transfer Protocol）去连接邮件服务器。我们想让 SQL Server 来发送邮件，首先要告诉它用户名称，密码，服务器地址，网络传送协议，邮件服务器的端口。。。等信息。 -- 以下脚本实现了数据库邮件的配置： ----下面是具体的配置邮件步骤 ----在 sa 系统帐户下运行。 -- --1. 启用 SQL Server 邮件功能。 use master go exec sp_configure 'show advanced options',1 go reconfigure with override go exec sp_configure 'Database Mail XPs',1 go reconfigure with override go --2. 在 SQL Server 中添加邮件帐户（account） exec msdb..sysmail_add_account_sp @account_name = '163yx' -- 邮件帐户名称（SQL Server 使用） ,@email_address = 'kk_XXXX@163.com' -- 发件人邮件地址 ,@display_name = null -- 发件人姓名 ,@replyto_address = null ,@description = null ,@mailserver_name = 'smtp.163.com' -- 邮件服务器地址 ,@mailserver_type = 'SMTP' -- 邮件协议（SQL 2005 只支持 SMTP） ,@port = 25 -- 邮件服务器端口 ,@username = 'kk_XXXX@163.com' -- 用户名 ,@password = 'XXXXX' -- 密码 ,@use_default_credentials = 0 ,@enable_ssl = 0 ,@account_id = null --3. 在 SQL Server 中添加 profile exec msdb..sysmail_add_profile_sp @profile_name = 'dba_profile3' -- profile 名称 ,@description = 'dba mail profile' -- profile 描述 ,@profile_id = null -- 在 SQL Server 中映射 account 和 profile exec msdb..sysmail_add_profileaccount_sp @profile_name = 'dba_profile3' -- profile 名称 ,@account_name = '163yx' -- account 名称 ,@sequence_number = 1 -- account 在 profile 中顺序 --5. 利用 SQL Server Database Mail 功能发送邮件。 exec msdb..sp_send_dbmail @profile_name = 'dba_profile3' -- profile 名称 ,@recipients = 'kk_XXXX@163.com;kk2_XXXX@163.com' -- 收件人邮箱 ,@subject = 'SQL Server Mail 测试' -- 邮件标题 ,@body = 'Hello Mail!测试' -- 邮件内容 ,@body_format = 'TEXT' -- 邮件格式 ,@file_attachments = 'c:a.txt' --邮件附件 --6. 查看邮件发送情况： use msdb go select * from sysmail_allitems select * from sysmail_mailitems select * from sysmail_event_log --如果不是以 sa 帐户发送邮件，则可能会出现错误： -- --Msg 229, Level 14, State 5, Procedure sp_send_dbmail, Line 1 --EXECUTE permission denied on object 'sp_send_dbmail', database 'msdb', schema 'dbo'. -- --这是因为，当前 SQL Server 登陆帐户（login），在 msdb 数据库中没有发送数据库邮件的权限，需要加入 msdb 数据库用户，并通过加入 sp_addrolemember 角色赋予权限。假设该SQL Server 登陆帐户名字为 “dba” -- --use msdb --go -- --create user dba for login dba --go -- --exec dbo.sp_addrolemember @rolename = 'DatabaseMailUserRole', -- @membername = 'dba' --go -- --此时，再次发送数据库邮件，仍可能有错误： -- --Msg 14607, Level 16, State 1, Procedure sp_send_dbmail, Line 119 --profile name is not valid -- --虽然，数据库用户 “dba” 已经在 msdb 中拥有发送邮件的权限了，但这还不够，他还需要有使用 profile：“dba_profile” 的权限。 -- --use msdb --go -- --exec sysmail_add_principalprofile_sp @principal_name = 'dba' -- ,@profile_name = 'dba_profile' -- ,@is_default = 1 -- --从上面的参数 @is_default=1 可以看出，一个数据库用户可以在多个 mail profile 拥有发送权限。 --EXEC msdb.dbo.sysmail_configure_sp 'MaxFileSize', 100000000 （字节）设置邮件.note
配置操作员
操作员主要是用于作业的通知对象：
配置如下：
USE [msdb] GO EXEC msdb.dbo.sp_add_operator @name=N'mail_user2', @enabled=1, @pager_days=0, @email_address=N'KK_XXXX.163.COM' GO
注 ：操作员可根据是否在作业成功或失败时通知，后续脚本均未配置操作员，如需配置可在作业属性中自行添加

节点切换作业控制
作业可以采用手动控制或如下脚本，也可以修改作业在作业执行前增加节点判断
--------------------------判断当前节点是否为主节点 如果不是则禁用作业 ------- ------------节点 切换为主节点则启用JOB ------------ DECLARE @ROLE tinyint DECLARE @ENABLE tinyint ----判断是否是主节点 --1 主节点 SELECT @role=role FROM sys.dm_hadr_availability_replica_states WHERE is_local=1 --判断JOB状态 --0 禁用 1 启用 --以syspolicy_purge_history 为 参照 --如果 禁用或删除syspolicy_purge_history请修改 @ENABLE下段查询 SELECT @ENABLE = [ENABLED] FROM MSDB.[dbo].[sysjobs] WHERE NAME = 'syspolicy_purge_history' -----第一次切换 辅助节点没有创建CDC作业 job 则创建作业 [category_id] = 13 CDC LOG SCAN JOB if not exists (select 1 from msdb.dbo.sysjobs where [category_id]= 13 or [category_id]= 16 ) and @ROLE = 1 begin EXEC sys.sp_cdc_add_job @job_type = 'capture'; EXEC sys.sp_cdc_add_job @job_type = 'cleanup'; end ---primary and job disable set job enable IF @ROLE = 1 and @ENABLE = 0 BEGIN ----如果存在原有作业为禁用,无法确定哪些JOB需要开启....所以此处最好手动维护作业的启用和禁用 EXEC msdb.dbo.sp_update_job @job_name = N'XXXXX', @enabled = 1 ; -----执行 CDC EXEC msdb.dbo.sp_start_job @job_name = N'cdc.XX_capture' EXEC msdb.dbo.sp_start_job @job_name = N'cdc.XX_cleanup' end ---not primary and job enable set disable IF @ROLE <> 1 and @ENABLE = 1 BEGIN ----如果存在原有作业为禁用,无法确定哪些JOB需要开启....所以此处最好手动维护作业的启用和禁用 EXEC msdb.dbo.sp_update_job @job_name = N'XXXXX', @enabled = 0 ; END
数据备份
备份方案：每天全备份、6小时一次差异备份、一小时一次日志备份。
备份存储过程
存储过程创建后会保留在master库中，存储过程主要控制备份逻辑，备份路径等。
存储过程中只有一个类型参数，用于控制全备/差异/日志备份，可根据需要修改。
