Mirror Server Instance (Configure Database Mirroring Security Wizard)

Use this page to specify information about the server instance with the mirror database.

Important note Important

The mirror server instance must be running the same edition of SQL Server, either SQL Server 2005 Standard or SQL Server 2005 Enterprise Edition, as the principal server instance. Also, we strongly recommend that they run on comparable systems that can handle identical workloads.

To configure database mirroring by using SQL Server Management Studio

Mirror server instance

If a mirror server instance is already specified (on the Mirroring page of the Database Properties dialog box), that instance is displayed; for more information, see Database Properties (Mirroring Page).

Otherwise, enter the name of the mirror server instance. Note that the mirror server instance cannot be the same as the principal server instance.

Connect

If a mirror server instance has not been specified, click Connect. This displays the Connect to Server dialog box in which you can specify the server instance and establish a connection.

If the instance has been specified, but the wizard lacks a connection with sufficient permission to check for the existence of the endpoint, click Connect. This displays the Connect to Server dialog box with the server instance pre-selected and unchangeable. Specify a domain account with sufficient permission, and connect to the server instance.

Note Note

When connecting to the server instance, the Configure Database Mirroring Security Wizard uses the credentials provided in the Connect to Server dialog box. These are different from the credentials of a mirroring session, which uses the credentials of the startup account where the server instance is running as a service.

Listener Port

The behavior of this option depends on whether the mirroring endpoint exists for this server instance, as follows:

  • If a listener port does not exist for the server instance, port number 5022 is displayed in the Port text box. You can use any available port number, such as 7022.

  • When the mirroring endpoint already exists, the port number from that endpoint is displayed. If you need to change the port, use an ALTER ENDPOINT command. For more information, see ALTER ENDPOINT (Transact-SQL).

    Note Note

    A port number is required.

Endpoint name

If the mirroring endpoint exists for this server instance, the endpoint name is displayed here. If the endpoint does not exist, you can specify the name of the endpoint.

Encrypt data sent through this endpoint

By default, encryption is enabled. When enabled, encryption is required (not merely supported) and uses the default values for all of the encryption options. For more information, see CREATE ENDPOINT (Transact-SQL).

To disable encryption, clear the check box. To re-enable encryption, select the check box.
