SQL Server 安装后部分选项初始化脚本

SQL Server安装后，根据对应的业务场景，数据库实例的部分选项需要调整，例如实例的最大内存、tempdb 文件的增长量、Job执行记录数等等，但这一步经常被大家忽略掉。

其实很多选项初始化都可以通过脚本实现，一件执行。下面是一些常见选项初始的例子，仅供大家参考。

use master
go
--show advanced options
sp_configure 'show advanced options',1
reconfigure with override
go
PRINT 'show advanced options ok'
GO

--Enable extend stored procedure xp_cmdshell
sp_configure 'xp_cmdshell',1
reconfigure with override
Go
PRINT 'enabled xp_cmdshell ok'
GO

---------------------------------------------------------
---------Configure how many memory server will used------
---------------------------------------------------------
declare @i as bigint
select @i=ceiling(total_physical_memory_kb/1024/1024.0) From sys.dm_os_sys_memory
    if @i*0.2>20
        begin
            --set @i=(@i-10)*1024
            set @i=20*1024
        end
    else if @i*0.2<4
        begin
            set @i=4*1024
        end
    else
        begin
            set @i=@i*0.8*1024
        end
--Configure how many memory server will used
exec sp_configure 'max server memory',@i    --（该参数根据Sever内存大小具体决定）
Reconfigure with override
GO
PRINT 'set max memory ok'
GO

 --Set database Compress Backup
EXEC sp_configure 'backup compression default', '';
RECONFIGURE WITH OVERRIDE

-----------配置代理错误日志文件-------------------------------------------------------
exec msdb.dbo.sp_set_sqlagent_properties @jobhistory_max_rows=50000,@jobhistory_max_rows_per_job=100
GO
PRINT N'配置代理错误日志文件 成功'
GO

----------configure temp db's file growth ------------
ALTER DATABASE [tempdb] MODIFY FILE ( NAME = N'tempdev', FILEGROWTH = 100MB )
ALTER DATABASE [tempdb] MODIFY FILE ( NAME = N'templog', FILEGROWTH = 100MB )

----Enable create ole auotmation (sp_oacreate)
--sp_configure 'Ole Automation Procedures',1
--reconfigure with override
--GO
--PRINT 'enabled sp_oacreate ok'
--GO

----Enable distributed query/transaction in AD HOC query like opendatasource/operquery
--sp_configure 'Ad Hoc Distributed Queries',1
--reconfigure with override
--Go
--PRINT 'enabled  opendatasource/operquery ok'
--GO
