批量修改所有服务器的dbmail配置(推荐)
最近遇到这样一个案例,需要修改所有SQLServer的DatabaseMail的SMTP,原来的SMTP为10.xxx.xxx.xxx,现在需要修改为192.168.xxx.xxx,另外需要规范邮件地址,以前这类邮件ServerName@yoursqldba.com的后缀需要修改为ServerName@xxxx.com(信息做了脱敏处理)。
如果使用SSMS客户端的UI界面去修改的话,那么多服务器一台一台去修改,不仅费时费力,而且枯燥无聊。只能使用脚本,一旦写好一个脚本,而后使用MultipleServerQueryExecution(极力推荐使用这个管理、维护数据库),执行一次脚本,全部搞定。剩下的时间你可以喝喝茶、学习下新知识!
