数据库的运维策略脚本篇(内附脚本,无私分享)

  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

            print(@email_conetent)

                @subject = @subject_str,                 --邮件主题
                @body = @email_conetent    
        end 

 

 

 

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。

Agent作业备份

  备份作业可以通过备份MSDB完成,但是保留一份脚本还是不错的,脚本为存储过程,建议一个周或一个月备份一次,可使用JOB 调用存储过程。

  

USE [master]
GO

SET ANSI_NULLS ON

SET QUOTED_IDENTIFIER ON

alter PROCEDURE [dbo].[usp_DumpJobsql]
