This post covers how worker threads function, their management, and the impact on database availability and performance, with practical tips on calculating and monitoring thread usage to optimize your SQL Server configurations.
The DNN Listener: Guide to Distributed Network Names (DNNs) for SQL Server VMs
This guide explores Distributed Network Names (DNNs) for managing AlwaysOn Availability Groups on Azure SQL Server VMs. It explains how DNNs differ from Virtual Network Names (VNNs), highlights the benefits of DNNs (simplified configuration, enhanced flexibility, improved availability), and provides a step-by-step walkthrough for setting up a DNN listener using PowerShell.
Understanding Availability Group Synchronization in SQL Server
A fundamental aspect of managing Availability Groups is understanding how data synchronization occurs between the primary and secondary replicas within the group. This process ensures that all replicas are up-to-date, reflecting changes made in the primary database across all secondary databases in the group. Let’s look into how this synchronization works and the importance of the ‘redo’ operation in maintaining data consistency.
Flow Control in Availability Groups and SQL Server 2022 Enhancements
SQL Server’s flow control in Availability Groups ensures optimal resource usage by managing log message distribution, thus safeguarding system performance. This mechanism operates seamlessly without compromising replica synchronization, with monitoring options available for detailed analysis. The latest iteration in SQL Server 2022 further refines flow control, enhancing the database’s efficiency and stability.
Enhancing Data Durability with SQL Server’s REQUIRED SYNCHRONIZED SECONDARIES TO COMMIT Feature
SQL Server 2017 marked a significant advancement in high availability architectures by introducing the REQUIRED_SYNCHRONIZED_SECONDARIES_TO_COMMIT setting. This feature enhances data protection and integrity within Availability Groups (AGs) by meticulously controlling the transaction commit process across replicas. Its role has continued to be pivotal in subsequent releases, including SQL Server 2022, showcasing Microsoft’s commitment to robust data protection mechanisms.
