Why Is an Error Reported When I Attempt to Delete a Database from RDS SQL Server Primary/Standby DB Instances?

Symptom

An error shown in Figure 1 is reported on SQL Server Management Studio when a database is being deleted from RDS SQL Server primary/standby DB instances.

The database 'xxxx' is enabled for database mirroring. Database mirroring must be removed before you drop the database. Error: 3743

Figure 1 Error information

Possible Causes

The error details indicate that the SQL Server DB instance type is primary/standby and database mirroring is enabled for the standby DB instance. As a result, the database cannot be deleted.

Solution

Before deleting the database, run the following commands to disable the mirroring:

Use master

go

ALTER DATABASE [Database_Name] SET PARTNER OFF;

GO

Once database mirroring is disabled, the database can be deleted.
