创建自定义SQL数据库镜像警报
Create Custom SQL Database Mirror Alerts

以下是一些你可以用在任何作业上的sql逻辑（logic）。创建数据库镜像警报程序。作业旨在检查所有数据库（不包括系统级别），以确保它们已根据其Create_Date或Restore_Date（最新的）配置为镜像。它不检查镜像数据库。只检查Principals。 这可以部署在当前被配置使用数据库镜像的任何SQL Server实例中。在Primary或Secondary上部署是安全的。如果尚未配置数据库，则会编译一个所述数据库的创建/恢复日期的列表，并发送一封电子邮件。此外， 它只会检查在其上配置了Principal的数据库实例，因此如果你想在Mirror上创建此作业，请随意。在将数据库配置为服务器上的Principal之前，它不会执行任何操作。因此，只要数据库实例通过“set partner failover”进行故障转移， 作业就会开始运行。 下面是收到的邮件的样子：

Here’s some sql logic you can throw into any Job. Create Database Mirror Alert Process. Job is designed to check all databases (excluding system level) to ensure they have been configured for Mirroring based on their Create_Date or Restore_Date (which is most recent). It does NOT check Mirror Databases. Only Principals. This can be deployed across any SQL Server Instance that is currently configured to use Database Mirroring. It is safe to deploy on both Primary or Secondary. If databases have not been configured it compiles a list along with the create/restore dates of said databases, and sends an email. Additionally it will ONLY check Database Instances that have Principals configured on them so if you want to create this Job on the Mirror feel free. It won’t do anything until a database has been configured as the Principal on the Server. So whenever the Database Instance fails over via ‘set partner failover’, then the Job will start running.
Here is what the email will look like:
Here is what the Job will do exactly.
- Check to see if SQL Database Mail has been configured.
- Configures SQL Database Mail (automatically) if it does not find the configuration. You will need to supply the SMTP Server Name below.
- Sends a test email once SQL Database Mail has been configured.
- Checks to see if ALL databases (excluding system databases) has been configured for SQL Database Mirroring.
- Creates a temporary table to hold database Names, Create_Date, and Restore_Date.
- Emails Database List.
以下是作业将要做的事情。
- 检查是否已配置SQL数据库邮件。
- 如果找不到配置，则自动配置SQL数据库邮件。 需要你在下面提供SMTP服务器名称。
- 配置SQL数据库邮件后发送一封测试电子邮件。
- 检查是否已为SQL数据库镜像配置了所有数据库（不包括系统数据库）。
- 创建一个临时表来保存数据库的Names，Create_Date和Restore_Date。
- 发送数据库列表电子邮件。
