Sql mirroring manual failover

In the "Messages" tab you will find the script to proceed with the failover of the databases. If you run this on the Mirror instance and the databases are acting as the mirror, then you will only get informative output in the "Messages" tab, instead of actionable T-SQL commands to be applied. Here is the output. Nothing too crazy for this mode, you will simply get the status of the databases and absolutely nothing in the "Messages" tab.

This is the command to actually perform the failover of all the databases instead of just obtaining the T-SQL code. Here's the code to create the Stored Procedure on each instance. This was created in the master database for demonstration purposes, but you can put in any database you want.

Yeah, we're on the same page.

Step 8: In the next screen, it is time to configure the service accounts. The service accounts dialog box contains fields for the domain service accounts of the principal, mirror, and witness server instances. If the server instances all use the same service account, leave the fields blank. I have used the same service accounts for all instances, so I will leave this section blank. Step 9: The next step in the wizard is to verify all the details which you want to change or keep for this configuration.

Verify the details and click on the "Finish" button as shown in the below screenshot. Once you click on the "Finish" button, the "Configuring Endpoints" window will load with the status of the witness configuration for both the principal and witness server instances as shown in the below screenshot.

Now click on the "Close" button to complete the process. Once you click on the "Close" button of the above screenshot, the wizard returns you to the Database Properties dialog box where the server network address of the witness now appears in the Witness field as we can see in the below screenshot.

We can see one more thing here by comparing the above screenshot with the one shown in step 3. Here you can see the operating mode of this configuration has been changed from "High safety without automatic failover" to "High safety with automatic failover".

Therefore we can validate that the witness server has been added to the existing SQL Server Database Mirroring configuration.

We can also validate the witness configuration by running the same command in step 1. Now the mirroring witness state should have a value of "Connected" as shown below. Related Articles.
