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 [...]

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 [...]

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 [...]

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 [...]

This is a quick announcement that Method-R is organizing the online class reunion for the participants of their Mastering Oracle Trace Data classes. Cary Millsap and Ron Crisco will entertain us with stories and useful tips around processing and analyzing Oracle 10046 traces. Having Method-R done special training for Pythian about a year ago, I [...]

This release is just a quick bug fix release of an older 1.1.1 version of the plug-in. It’s long overdue but I’ve managed to fix “” problem only couple weeks ago. I’ve distributed the new version to the folks who have reached out to me by email of via blog reporting the issue in the [...]

This blog post covers day 0 of UKOUG 2011 — Sunday, 4th of December, 2011. Since there were so many of us from Pythian at the conference, I’m adding my name in the blog post title. I think I will be doing it for all conference posts as I think I’ve been doing for some [...]

My good friend (and personal hero) Cary Millsap is doing a series of one day classes around the world — Mastering Oracle Trace Data. One of them is conveniently scheduled in Birmingham Thursday next week right after the UKOUG Conference. It’s not far from the Birmingham ICC where the UKOUG Technology and Business Suite Conference [...]
