The Story of Locks by Application Issues
On the 20th of April, query load times usually ranged from 12 to 15 seconds per snapshot, but there was a notable spike exceeding 2,000 seconds during certain periods. This anomaly suggested a deeper issue, prompting a detailed investigation. By examining the correlation between locks and application issues, executions, disk reads, and buffer writes, a significant overlap was found between increased query durations and intensified locking issues. Accessing the lock history tab provided detailed data on each lock event, including the time, duration, and specific database elements affected.

Why Oracle Changes the Execution Plan for a Query?
Understanding why Oracle changes the execution plan for a query can save you a lot of time and headaches. Statistics, data distribution (even without updated statistics), schema changes, and much more — There are numerous factors behind the changes of the execution plan. Having a grasp on all of them helps maintain efficient and stable query performance.

How can you speed up database read queries
Before getting into the technicalities of speeding up your database read queries, the first step is always to have a clear understanding of what exactly you need. This might sound straightforward, but inefficient queries often begin with uncertainty about the data requirements. Knowing exactly what information is necessary for your application or analysis not only helps in crafting precise queries but also prevents the database from retrieving extraneous information, which can significantly slow down performance.

Data Observability
Too often when looking at the data we see just numbers – columns and rows that might seem meaningful on the surface but lack depth without proper context. Data observability changes this perspective. This approach is about understanding what the numbers really tell us about the health, accuracy, and vitality of our data systems.
Data observability isn’t just one thing – it’s an ability, or rather a way of monitoring your data’s health, accuracy, and overall usefulness. It’s what equips data teams with the essential tools they need in order to make sure that the data that’s driving business decisions is not only there but also high-quality, well-structured, and up-to-date.

That’s How Effective Query Monitoring Can Prevent Locks
In the complex ecosystem of SQL Server, performance issues can sometimes feel like detective work, especially when tracking down the elusive culprits behind system locks. This time, we’re exploring how ineffective queries (and poorly executed query monitoring) can grind operations to a halt, and how to identify the “how” and “why” behind the halt.
From scrutinizing load trends to dissecting lock histories and refining execution plans, we’re making sure that no stone—or should we say, no data block—remains unturned in our quest to keep SQL Server zipping along like a sports car rather than trudging like a pack mule.

The Replication Dichotomy: Logical vs Physical Replication
There’s a peculiar habit among some database professionals occasionally to toss logical and physical replication into the same bin. One might as well say socks and shoes are the same because, after all, they both go on your feet, right? But as anyone who’s tried wearing socks in the snow can attest, similarities on the surface can hide a whole universe of differences between logical vs physical replication.
Blurring together logical and physical replication, or neglecting their differences can lead to inefficient data management strategies. Each method has its merits and ideal scenarios of use. Knowing just when to apply each one—understanding their unique roles in the spectrum of data management—helps avoid unnecessary workload, optimizes performance, and ensures data integrity.

Execution Plan Changes in SQL Server: Reasons and Solutions
Executions plan—complex maps charted by the SQL Server optimizer, dictate the most efficient route for data retrieval. However, the plans are not static. They morph and adapt, influenced by a host of factors ranging from data volume changes to system upgrades. Each of the execution plan changes in SQL Server has the potential to sway performance dramatically.
Understanding the reasons behind these shifts, and more importantly, how to effectively manage them translates to maintaining optimal performance in SQL Server environments.

The Domino Effect in the T10 Database on g1rush Server
Performance issues rarely occur in isolation. Often, a single problem can trigger a cascade of related issues, each compounding the overall impact on the system. This case study explores such a scenario in the T10 database on the g1rush server.

From Analysis to Action: Overcoming Execution Plan Changes
Execution plans choose the way in which SQL queries are executed by the database engine. As such, they are a difference between a smoothly running database and one that stumbles under load. Sometimes, an execution plan changes, for various reasons—often silently and without warning—and the far-reaching fallout can be huge.
The most immediate impact seen as the execution plan changes is a decline in query performance. A query that once ran smoothly in milliseconds might, due to an altered plan, start consuming seconds. This increase in query time can cascade into longer load times for applications, frustrated end-users, and severe financial repercussions in high-stakes environments such as financial trading platforms or real-time data services.

Performance Monitor Changes in Version 2024.2—Part I: Online Monitor
Statistics can lie—” The only statistics you can trust are those you falsified yourself” This old adage attributed to Sir Winston Churchill rings especially true if you’re dealing with daily database monitoring. When data is only captured in 15-minute intervals, transient issues that can severely impact performance might slip through the cracks, unnoticed and unaddressed until they’ve already caused significant problems.
In the newest release of the DBPLUS PERFORMANCE MONITOR, we’re extremely excited to show you the solution that the new functionality brings to the table.
