Advert: Few Oracle Database Appliances at significant discount

This blog is a little bit self serving and I’d normally not post it but I think that it would be an awesome deal for those of you who are thinking of buying an Oracle Database Appliance now. We have several just two left brand new, unopened ODAs left in our inventory that we need to move. Half of them are gone to our customers but there are few still left. We are not really interested in holding on to them while somebody else can put them to good use so we have very very (did I say very?) good price. :) Limited time offer as they say.

Hardware Components Failures – Survey Results

When preparing for the the IOUG Collaborate 12 deep dive on deploying Oracle Databases for high Availability, I wanted to provide some feedback on what hardware components are failing most frequently and which ones are less frequently. I believe I have reasonably good idea about that but I thought that providing some more objective data would be better. I couldn’t find and results of a more scientific research so I decided to organize a poll. This blog post shows the results and I promised to share it with several groups.

Storage Replication for Oracle Database and Licensing

While doing my high availability deep dive at Collaborate 12 few weeks ago, I stated that storage replication qualifies for the cold failover licensing rules (see slide #128). During collaborate I spoke to one person at Oracle who definitely knows the rules. Simon Haslam also reached out to me by email pointing out that things...

Quick blog post from Collaborate 2012 in Vegas. I’m only doing one session this year but it’s a very long session — I’ve just done a deel dive on deploying Oracle Database 11gR2 for High Availability. It’s a broad topic and my plan was to focus a lot on basic concepts and how they are [...]

Just a quick heads up to the ODA customers — there is a critical patch 2.1.0.3.1 out that is applied on top of ODA patch bundle 2.1.0.3.0. This patch has an important fix for a bug causing ODA servers to shutdown in some situations when an ASM disk is lost. The patch number is 13817532 [...]

Oracle Database Appliance — Storage expansion with NFS (dNFS, HCC)

The biggest objection to Oracle Database Appliance (ODA) we hear from customers is about 4TB usable space limit (tripple mirrored 12TB of raw storage). I think most of the times this is more a perceived barrier rather than objective — more along the lines of being afraid to hit the limit if the system grows [...]

2001: Oracle Database Appliance by Dell — Déjà vu

Stumbled upon this Dell’s article from 2001 — The Oracle Database Appliance by Dell: Architecture and Features. The idea of appliance-like platform for Oracle database is obviously not new but the latest implementation of Oracle Database Appliance makes the most sense from all previous attempts (comments are open below to disagree if you’d like). What [...]

Oracle Database Appliance (ODA) Patch Bundle 2.1.0.3.0 Fixes CPU Performance Issue

If you are using Oracle Database Appliance (ODA) then this patch is very important to apply. The patch bundle 2.1.0.3.0 has been published just this week and the most important fix from my perspective is the new BIOS version 12010304. Intel CPUs have a feature called Software Controlled Clock Modulation that allows programmatically control of [...]
