This article shows how to deploy a domain-independent Windows Failover Cluster for SQL Server Always On Availability Groups. In this series, we configured the SQL Server Always On Availability Groups beginning from virtual server build. Always On provides a robust high availability and disaster recovery solution in SQL Server.
In this series, we configured the SQL Server Always On Availability Groups beginning from virtual server build. Always On provides a robust high availability and disaster recovery solution in SQL Server. It integrates the Windows failover clustering with the database mirroring concepts. For a traditional availability group, we should have the following configurations.
Windows Server 2016 introduced a new concept known as domain-independent Windows failover clusters. In this article, we are going to explore this new concept and see how we can leverage this for SQL Server Always On Availability group configuration.
As explained above, in a traditional failover cluster for SQL Server Always On, all participating nodes must be a member of the Domain.
In the above image, we have two servers [ServerA] and [ServerB]. Both servers are a member of the ABC.COM domain. We have configured an availability group between these servers.
In the Windows Server 2016, we can create the domain-independent failover clusters as well. Let’s create the cluster in the subsequent section.
Note: In this article, we do not go in detail with each step. You can refer to previous articles for detailed steps.
As a part of the prerequisite, I have prepared two virtual machines, SQLAG1 and SQLAG2. Both virtual machines are not part of any domain.
Navigate to the Add Roles and Feature Wizard in the server manager and enable the failover clustering feature, as shown below. It installs failover clustering along with its dependencies.
In the next screen, we can verify that the failover clustering feature is enabled on the node AG1.
Similarly, enable the failover cluster feature on the second virtual machine [SQLAG2].
SQL stands for Structured Query Language. SQL is a scripting language expected to store, control, and inquiry information put away in social databases. The main manifestation of SQL showed up in 1974, when a gathering in IBM built up the principal model of a social database. The primary business social database was discharged by Relational Software later turning out to be Oracle.
This article gives an overview of SQL Server Always On Availability Group features. We configured the SQL Server Always On Availability Group from the beginning of building virtual machines.
SQL GROUP BY clause in SQL is used to arrange the same data into groups with the help of some functions. SQL GROUP BY is also used with aggregate functions.
This article will provide a review on how to configure Always On Availability groups in AWS EC2 instances and AWS FSx as file share witness.
Debug SQL stored procedures and develop your SQL database project with dbForge SQL Complete, a new add-in for Visual Studio and SSMS. When you develop large chunks of T-SQL code with the help of the SQL Server Management Studio tool, it is essential to test the “Live” behavior of your code by making sure that each small piece of code works fine and being able to allocate any error message that may cause a failure within that code.
