From Clustered to Specialized: Types of SQL Indexes and When to Use Them
Considering the sheer volume of data slugging through the digital pipelines, knowing your indexes shou be your bread and butter. Here, we’re slicing through the thick crust of complexity to expose clustered and non-clustered indexes and their cousins.
Why bother? Because we live at the age of instant grafitication. The speed at which you can retrieve data can be the difference between leading and trailing behind. That’s why we will be going through the ins and outs of clustered and non-clustered indexes and their specialized kin. On they way, keep in mind that each type has a role. For every one there is a specific scenario where its purpose becomes the most obvious.
It’s about knowing who to tap for the performance you crave, at precisely the right moment.

Performance Monitor Changes in Version 2024.2—Part III: OS Stat Page
In the high-tech tangle of our time, more cores usually mean a slower tick-tock in the CPU clock. The sage database administrators find themselves revisiting the old battleground of processor usage. The latest update to DBPLUS Performance Monitor (Version 2024.2) includes significant enhancements that aid in this monitoring. Particularly through its dedicated page for OS statistics—OS Stat Page.

10 Good Practices for Database Backups
The act of backing up databases may seem like a routine chore but it’s an art form, practiced by those who maneuver through the digital aisles with the finesse of a cat burglar and the foresight of a chess master. Much like a well-timed joke or a perfectly brewed cup of coffee, timing in backups is everything.
It ensures that the digital lifeblood of your business keeps pulsing through the veins of your operations, even when fate throws a wrench in the works. This set of good practices for database backups may not make you a master of all, but it will certainly steer you clear of the most dangerous (and costly) mistakes.

When the Intern Deletes the Entire Database
We’ve all been the rookie, the greenhorn, the junior in the office. Some of us may have stumbled through minor blunders, but few can claim their mistakes shut down entire systems or wiped clean a whole database. Such extreme cases, we will be focusing on today, demonstrating the fragile boundary that exists in the digital environments of modern corporations. Let’s see what happens when the intern deletes the entire database.

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.
