Navigating the Changes in SQL Server 2022: A Guide to Server Alias Configuration
If you’re embarking on a fresh installation of SQL Server 2022, you might be in for a surprise. Gone are the familiar days of the SQL Server Native Client being a core component of SQL Server installations. This blog post will discuss the recent changes in SQL Server 2022 and how to navigate server alias configuration in this new landscape.
Optimizing Large Tables in SQL Server Using Table Partitioning
SQL Server table partitioning is an invaluable feature for improving database performance and management, especially for large-scale databases. This blog post provides an overview of setting up and managing partitioned tables in SQL Server, using TSQL commands. Partitioning helps manage large tables by dividing them into smaller, more manageable segments known as partitions. Each partition can be stored on a separate filegroup, enhancing query performance and simplifying maintenance tasks such as backups and index rebuilds.
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.
System Level Performance Tuning for SQL Server 2022 on Linux
Running SQL Server on Linux offers many advantages, including cost savings and robust management tools. To fully realize these benefits, certain Linux-specific configurations must be tuned. This post focuses on three specific areas: I/O scheduler, swapfiles, and swappiness. So let’s jump in and start tinkering!
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.
Capturing SQL Server Inventory with PowerShell
Maintaining an accurate and comprehensive inventory of your SQL Server environment is crucial for effective database management, ensuring security, and meeting compliance requirements. With PowerShell, database administrators can automate the collection of detailed information about SQL Server instances and databases, streamlining the inventory process. This blog post introduces a PowerShell script designed to efficiently gather SQL Server inventory data, separating instance-level information from database-specific details into two distinct reports.
Optimizing SQL Server with the Tuple Mover and Columnstore Indexes
SQL Server’s performance and efficiency hinge on its ability to manage and store data effectively. At the heart of this capability are Columnstore Indexes and the Tuple Mover, a duo that works together to ensure data is stored efficiently, making it readily accessible for fast query execution. This post takes a look into the interplay between Columnstore Indexes and the Tuple Mover, highlighting the operational details and the impact of recent enhancements introduced in SQL Server 2019.
