Not a real post - but a recommendation... Kevin Closson, former Performance Architect within Oracle's Exadata development organisation, has (finally!) written a blog post about the new Exadata X3 model with it's claimed "Database In-Memory" marketing title. For the history of Exadata click here. But more importantly, for the insider view, click here: Oracle Exadata … Continue reading More on Exadata X3 “Database In-Memory” (but not by me)
Category: Databases
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.
Technology Hype Cycles
I had a great idea this week. It started because I wanted to write about Business Intelligence and the benefits of flash memory for Decision Support Systems, but realised that it's hard to mention those subjects these days without referencing Unstructured Data. That got me thinking that the hype surrounding Big Data and the way in which trends such … Continue reading Technology Hype Cycles
SLOB using Violin 6616 on Fujitsu Servers
I've been too busy to blog recently, which is frustrating because I want to talk more about subjects that are important to me such as Database Virtualization and the great hype around In Memory Databases. However, in the meantime I'd like to share some results from running SLOB (the Silly Little Oracle Benchmark) on Violin … Continue reading SLOB using Violin 6616 on Fujitsu Servers
In Memory Databases: HANA, Exadata X3 and Flash Memory (Part 2)
In the first part of this blog series on In Memory Databases (IMDBs) I talked about the definition of "memory" and found it surprisingly hard to pin down. There was no doubt that Dynamic Random Access Memory (DRAM), such as that found in most modern computers, fell into the category of memory whilst disk clearly … Continue reading In Memory Databases: HANA, Exadata X3 and Flash Memory (Part 2)
Thoughts on In Memory Databases (Part 1)
Everyone is talking about In Memory at the moment. On blogs, in tweets, in the press, in the Oracle marketing department, in books by SAP employees, even my Violin colleagues... it's everywhere. What can I possibly add that will be of any value? Well, how about owning up to something: I find myself in a bit … Continue reading Thoughts on In Memory Databases (Part 1)
Using Oracle Preinstall RPM with Red Hat 6
Recently I've been building Red Hat 6 systems and struggling to use the Oracle Preinstall RPM because it has a dependency on the Oracle Unbreakable Enterprise Kernel. I've posted an article on this subject and my methods for getting around it: Using Oracle Preinstall RPM with Red Hat 6
This system is not registered with ULN / RHN
One of the features of Wordpress is the ability to see search terms which are taking viewers to your blog. One of the all-time highest searches bringing traffic to my site is "This system is not registered with ULN"... and sure enough if I search for that phrase on Google my site is one of the top … Continue reading This system is not registered with ULN / RHN
Oracle Achieves Record TPC-C Benchmark
It appears that one or two of my previous posts may have inadvertently annoyed some people at Oracle, so I would like to try and make amends today by posting something extremely positive about the company which, lest we forget, made the "world’s first commercial relational database", backed Linux before it was a commercially viable option and … Continue reading Oracle Achieves Record TPC-C Benchmark
Exadata X3 – Sound The Trumpets
It's crazy time in the world of Oracle, because Oracle OpenWorld 2012 is only a week away. Which means that between now and then the world of Oracle blogging and tweeting will gradually reach fever pitch speculating on the various announcements that will be issued, products that will be launched and outrageous claims that will … Continue reading Exadata X3 – Sound The Trumpets
Database Virtualisation: The End of Oracle RAC?
A long time ago (2003) in a galaxy far, far away (Denmark), a man wrote a white paper. However, this wasn't an ordinary man - it was Mogens Nørgaard, OakTable founder, CEO of Miracle A/S and previously the head of RDBMS Support and then Premium Services at Oracle Support in Denmark. It's fair to say that … Continue reading Database Virtualisation: The End of Oracle RAC?
