编写日志传送自动化脚本

Question

是否可以编写所有日志传送配置的脚本？

例如：我需要编写一个作业，启动从服务器 A 到服务器 B 的两个数据库的日志传送。

该作业将在服务器 A 上运行。

顺便说一下，两者都是 SQL 2008 R2 Enterprise。

服务器A上有一个共享。 \serverA\Log

我相信这就是所需要的。 是否可以仅通过脚本来完成？ 我是否必须初始化数据库，或者是否有像 SSMS 这样的选项来自动初始化？

我必须手动创建职位吗？或者它的配置方式是否可以创造就业机会并对其进行管理？

它可以编写脚本吗？有人做过这样的事吗？ 有人有一个脚本可以做到这一点吗？

提前致谢。

这是完全可能的，并且可以通过日志传送设置 GUI 编写脚本。它生成的脚本中需要克服的唯一障碍将需要在同一脚本中连接到主数据库和辅助数据库。这可以通过使用 SQLCMD 的 SQLCMD 模式命令（使用 CONNECT 命令）来完成，确保在连接之间放置 GO。作为奖励，您还可以执行操作系统命令（复制、删除等），以便您也可以编写备份和恢复脚本。请参阅下面的示例。
