This article gives an overview of Configuring Managed Service Accounts for SQL Server Always On Availability Groups.
DBA uses services accounts to run the various SQL Services. Usually, we should use a separate service account for an individual server SQL Services.
If you maintain a large inventory of SQL Servers, you might think it is a cumbersome task to change and maintain the passwords for these servers. Once you change the service account password using SQL Server Configuration Manager, it also requires the restart of SQL Services. It might be a challenging task as well to get downtime for highly transactional applications.
We can leverage Group Managed Service Accounts (gMSA) in these cases. Let’s explore it in the subsequent section.
We have two kinds of managed service accounts in an active directory configuration.
To summarize, you get the following benefits using gMSA as the service account for SQL Services.
Let’s start configurations of the Group Managed Service accounts (GMSA) for SQL Server Always On availability groups.
We can configure and use the gMSA service accounts for Windows Server 2012 or later. In this article, we will work with Windows Server 2016.
Take an RDP of the active directory server and Launch active directory (AD) using DSA.MSC command.
Right-click on the domain name and choose New -> Group. Specify a group name as per your requirement or naming convention.
Click Ok, and it creates the AD group. Open this group and enter a description. It helps you to identify the security group and its purpose efficiently.
Click on Members. In the members, add the failover cluster nodes. I have SQLNode1, SQLNode2, and SQLNode3 virtual machines configured in a SQL Server Always On availability group.
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.
In this article, we will discuss configuring SQL Server Always On Availability Groups and perform failover validations. You should go through the following articles and build the infrastructure before proceeding with this article.
SQL Server 2016 provides a new feature Distributed Availability Group for disaster recovery purposes. It is a particular type of availability group that helps access the multiple failover clusters. In this article’s series, we configured a traditional Always On group. It has the following requirements.
This article configures SQL Server Always On Availability Groups on the domain independent Windows Failover Clusters. In the previous article, Deploy a domain-independent Windows Failover Cluster for SQL Server Always On Availability Groups, we learned the new capability in Windows Server 2016 to configure a domain-independent Windows failover cluster.
