Databases are the systems of record at the heart of the enterprise. They were designed for correctness, durability, and human-paced interaction – not for continuous, machine-driven access patterns.
As workloads evolve, the database remains the point of truth… but the assumptions around how it is accessed are starting to break.
Now is the winter of our discontent. But rather than dwell on what a terrible year 2020 has been, I thought I'd make my final post of the year something more positive... so I am going to look back on one of the (many) times I made a fool of myself, in the hope that … Continue reading How To Look Stupid (Part #612)
The public cloud is like a hotel – flexible and convenient but shared infrastructure. This article explains what that model really means for enterprise databases.
Cloud databases come with cost levers on-premises never had. This article examines what the Cloud DBA role actually looks like and why cost is now a core DBA concern.
From on-premises specialist to cloud DevOps generalist – the DBA role has absorbed every wave of infrastructure change. Cloud adds one genuinely new pressure: the monthly bill.

flashdba returns from retirement to ask the question nobody in the cloud conversation was asking: when 75% of databases move to the cloud, what actually happens to performance?
It came to my attention last November that I had crossed the one year anniversary since my last post on flashdba.com. I was so surprised that I immediately decided to write a new post, which took another three months. There are reasons why I'm no longer posting technical blogs about databases and flash, but I'll … Continue reading Oracle ASM and Thin Provisioning – How To Reclaim Space
Guest Post I'm excited announce another guest blog written by my good friend and funny-talking American cousin Nathan Fuzi. Like me, Nate comes from a database background but joined the all-flash storage revolution back in its infancy. Which means, like me, Nate how has a little tombstone on his résumé marked Violin Memory. But even though he … Continue reading The Flash Insider: To POC or Not To POC?
I've updated my install cookbooks page to include a new cookbook for installation of Oracle 11.2.0.4 Real Application Clusters on Oracle Linux 6.7. This is also the first one I've published since I left the employment of Violin Memory to work for Kaminario, so this install uses a Kaminario K2 All Flash Array. However, it applies very well … Continue reading New Installation Cookbook: Oracle Linux 6.7 with Oracle 11.2.0.4 RAC
Almost exactly a year ago I published a post covering my first impressions of the ASM Filter Driver (ASMFD) released in Oracle 12.1.0.2, followed swiftly by a second post showing that it didn't work with 4k native devices. When I wrote that first post I was about to start my summer holidays, so I'm afraid … Continue reading Oracle’s ASM Filter Driver Revisited
