xp_cmdshell 选项

SQL Server 2005 中引入的 xp_cmdshell 选项是服务器配置选项,使系统管理员能够控制是否可以在系统上执行 xp_cmdshell 扩展存储过程。默认情况下,xp_cmdshell 选项在新安装的软件上处于禁用状态,但是可以使用基于策略的管理或运行 sp_configure 系统存储过程来启用它,如下面的代码示例所示:

-- To allow advanced options to be changed.
EXEC sp_configure 'show advanced options', 1
GO
-- To update the currently configured value for advanced options.
RECONFIGURE
GO
-- To enable the feature.
EXEC sp_configure 'xp_cmdshell', 1
GO
-- To update the currently configured value for this feature.
RECONFIGURE
GO
