Breaking Down Distributed Databases: How Do They Work? When to Use Them?
Distributed databases—by storing data across a whole set of physical locations— allow organizations to manage data across multiple geographical locations with the semblance of a single unified system. What can companies gain with this choice?

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.

PostgreSQL vs Oracle: Choose the Right Database for Your Needs
PostgreSQL vs Oracle — an open-source framework that champions adaptability and accessibility versus a proprietary system designed for high throughput and scalability in enterprise environments. These two database systems, while both engineered to manage vast amounts of data, diverge significantly in their approach, philosophy, and intended user base.
PostgreSQL is a community-driven, flexible model that supports customization and supports innovation, making it ideal for entities that value agile and cost-effective solutions. Oracle, in contrast, targets large-scale operations with its performance-oriented architecture that ensures reliability and robustness under heavy loads.

Key Metrics for Reliable Database Replication
Database replication sounds simple enough: take data from one place and make sure it appears somewhere else, quickly and correctly. But anyone who’s spent time monitoring and troubleshooting replication knows it’s anything but straightforward. Networks fail, logs get backed up, and suddenly your secondary database is minutes (or hour) behind.
That’s why replication metrics matter.

ORA-00904: Invalid Identifier in Oracle Databases
When you’re working with Oracle databases, some errors pop up so regularly that DBAs almost recite them in their sleep. ORA-00904: invalid identifier is certainly one of those classic offenders. On the face of it, ORA-00904 indicates you’ve referenced a column or other identifier that Oracle can’t locate or doesn’t consider valid. Straightforward enough—maybe there’s a simple typo, or a missing column in your table. But there are subtler corners of Oracle that can trigger the same error even when you think you’ve done everything right.

Achieve Database Optimization Without Abandoning Normalization
High concurrency, scattered queries, unpredictable data growth—the usual suspects. When everything’s slow and your tables are bursting, you face a tough choice: enforce strict normalization for pristine data integrity or optimize aggressively to wring out every last drop of performance. Overly normalized schemas may lead to a maze of joins and hamper speed under heavy loads. Performance-driven shortcuts—like denormalizing key data—can bloat storage and complicate updates. Balancing database optimization and normalization isn’t always straightforward, but it is possible.

Database Performance Tuning – the Sensible Way: Collaborative Strategies, Clear Metrics, and Tested Changes
Databases are either the invisible workhorse that keeps everything running smoothly or the ticking time bomb that wakes you at 3 a.m. with catastrophic slowdowns. There’s rarely a middle ground. Performance tuning makes all the difference—especially when you combine actual metrics, meaningful collaboration, and a dash of common sense. A few checks here and there can save hours of panic later on, and nothing beats a stable, responsive system for making you look like the hero of the IT team.
Of course, it helps to have a reliable way to see what’s going on under the hood while performance tuning, keep everyone on the same page, and avoid applying fixes blindly. After all, a well-tuned database is happier, and so are the people who rely on it every day.

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.
