Checking Database Mirroring Configuration - Microsoft SQL

SQL Server database mirroring is a disaster recovery and high availability technique that involves two SQL Server instances on the same or different machines. One SQL Server instance acts as a primary instance called the principal , while the other is a mirrored instance called the mirror The below how to article will step you through the setup of both of these SQL mirroring solutions using T-SQL only. Note; when using the GUI to establish mirroring SQL Server will complain if trying to establish a mirror between two different editions of SQL Server (ie Standard vs Enterprise). Configuring this via T-SQL gets around this problem This service account should be part of the sysadmin SQL server role if it's not already granted so. 9. Click Finish to commit the endpoint configuration. 10. Start mirroring session. You would only do so if a full database backup and a transaction log backup from the principal server have been restored on the mirror server with no recovery. In the Next Page, Check the Witness Server Instance option: Mirror Configuration: 10.E: Choose the Port Number and Chage the Endpoint Name For the Principal Server. Mirror Configuration: 10.F: In the Next Page, Connect to the Mirror Server and Choose the appropriate Port Number and Endpoint Name for the Mirror Server. Mirror Configuration: 10.

Important note: Database Mirroring is a feature that is being phased out in favor of the newer SQL Server 2012 AlwaysOn Availability Groupsfor the purpose of High Availability (See my blog post. The original environment was SQL Server 2012 on server A. The new environment, running SQL Server 2016, is a three-node Availability Group with servers B, C, and D. I had already set up the AG with a test database in the new environment, with B as the primary and C and D as replicas. To upgrade with little downtime, I mirrored from server A to.

The SQL Server and SQL Server Agent Services accounts are running as domain users (DOMAIN\User). Windows Firewall is OFF for the sake of this example
  2. The database mirroring setup needs to be initiated from the principal server using the SQL Server Management Studio wizard or T-SQL code. At the beginning of the setup process, there's an option for choosing a witness SQL Server instance which is only required if the high safety with automatic failover mode is desired
  3. If you have mirroring configured in Synchronous (high safety) mode, that overhead might be enough to show delays in commits. Generally, transactions would be slightly slower since data must be written to both the primary log, and the mirror log before control is returned to the user

Recovery Using SQL Server Database Mirroring: Testing the Standby CommServe Host. After you build and configure database mirroring on the standby CommServe host, you must check its readiness periodically. When the production CommServe host is down, the standby CommServe host can serve as the production server for few days or weeks Every time a new database is created on the SQL instance, either at Principal [Or Mirror, in-case code is deployed on the mirror server as well, considering mirror instance acts as Principal at any point of time in future] in few seconds, the database configured with the mirroring and will be in sync with the principal database 2.Then we go to Computer Management > Service and Application > SQL Server 2005 Configuration > Network Configuration > Enable TCP/IP protocol. Also, we make sure that SQL SERVER port is 1433. 3. Then we check that the TCP/IP protocol is enabled or not. We go to Computer Management > Service and Application > SQL Server 2005 Configuration. To enable CommServe disaster recovery using SQL Server database mirroring, you need to first build and configure database mirroring on the standby CommServe host. In a database mirroring setup, CommCell services do not run at the same time on both the production CommServe host and standby CommServe host

On secondary - alter db set partner ='TCP://primary:5022' On Primary - alter db set partner ='TCP://secondary:5022' Now the mirroring setup is done Second tab will configure your Witness server settings. If you are using same server with different instances as I am using in my example then you need to change port number for each configuration step. If you did not ticked Witness server check box in Step 6 then this window will not appear. look at the listener port and End Point Name Found in SQL Server Standard Edition, this feature reportedly offers users the same functions as found in database mirroring.
