ORA-01555: How to Preserve Undo Data and Keep Queries Consistent
Oracle database has many problems and often recurring ORA-01555 is one of them. It is known as the “snapshot too old” error, and occurs when Oracle cannot provide a consistent read of the data that existed at the query’s start time. Oracle attempts to use undo data to roll back any changes made after the query began. If that undo information has been overwritten or otherwise lost, Oracle can no longer reconstruct its older version. This leads to the ORA-01555 exception.

Performance Monitor 2024.4: What’s New
Managing database performance is rarely straightforward, and the demands only keep multiplying. In response, DBPLUS Performance Monitor 2024.4 introduces new features that help you see exactly how queries behave across different platforms, track CPU usage at a glance, refine how and when alerts reach you, and unify session data.
If you prefer a monitoring tool that shows critical insights with less hassle, the latest version deserves your attention.

ORA-06512 Explained: Locating PL/SQL Errors the Right Way
ORA-06512 is often misunderstood as the primary cause of an Oracle error, when in reality it just pinpoints where an exception occurred in your PL/SQL code. The true issue usually lies in a preceding error, such as an unhandled exception or data mismatch, hidden earlier in the stack.
In contrary to ORA-12154 or ORA-00600—which typically point to direct connectivity or internal database failures—ORA-06512 simply acts as a line-number reference. It tells you where an error occurred, not why. But let’s start from the beginning.

Databases in 2025: New Architectures, Smarter AI, and Stronger Security
The year is 2025, and the databases that once seemed so clever have gotten old and cranky. They’re no longer content with sitting there, quietly holding onto rows and columns like good little librarians. Nope. Now they’ve got opinions. They’ve got styles. They’ve got ideas about how to organize themselves, how to spread out across the clouds, how to speak human language, and how to lock the door behind you when you’re done rummaging through their shelves.
The old way of doing things — shoving everything into a single warehouse and hoping for the best — is about as appealing as canned spinach. So, what will we do instead?

The Intersection of Quantum Computing and Database Management
Databases are the engines powering our digital age, storing, managing, and retrieving the vast amounts of data generated every second. For decades, they’ve relied on classical computing to do the heavy lifting, using algorithms and hardware that have become increasingly optimized but still face fundamental limits. As datasets grow larger and more complex, and as the demand for real-time insights and advanced security rises, it’s becoming clear that classical systems alone may not be enough to meet these challenges. What then? Two words: quantum computing.

The Toughest Performance Challenges of SQL Server
SQL Server has a stellar reputation among the suits in the boardroom—lauded for its architecture and the ability to juggle massive datasets with the grace of someone who can juggle quite well. Yet, those who actually wrestle with the data, know a different story. They understand that SQL Server, like any towering giant, has its own set of quirks and foibles that can keep database professionals on their toes. Welcome to the performance challenges of SQL Server.

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.
