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 might not be that rosy. I will update the slides accordingly. In any case, please do your own homework and don’t trust my conclusions here — don’t take this as licensing advice by any means.
These are my personal rules to moderate the public forums on LinkedIn. I’ve posted on that topic in the discussion on the IOUG Exadata SIG forum. As I’m passing RAC SIG group to the next folks on the board (I’m the RAC SIG president until end of August), I needed to hand over my forum management duties too. I decided that it might be useful to the wider audience, so why don’t I just publish this on the blog?
This is a 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 deep 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 work.
Just a quick heads up to the ODA customers — there is a critical patch 188.8.131.52.1 out that is applied on top of ODA patch bundle 184.108.40.206.0. This patch has an important fix for a bug causing ODA servers to shutdown in some situations when an ASM disk is lost.
The 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 a lot. Nevertheless, Oracle has been always listening customers’ concerns when it comes to purchasing barriers. Of course, this time is no exception.
Stumbled upon this Dell’s article from 2001, So what do we see 10 years later? Singe device, no fuss, everything pre-configured, Oracle RAC, simplified operations — dream of 2001 finally coming true?
Quick post congratulating Gwen Shapira on becoming Oracle ACE Director. Gwen has be an Oracle ACE for a while by now and been very active in the community. Congratulations Gwen!
If you are using Oracle Database Appliance (ODA) then this patch is very important to apply. The patch bundle 220.127.116.11.0 has been published just this week and the most important fix from my perspective is the new BIOS version 12010304.
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.
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 past few months and they all confirmed that the new version is working fine so I’m releasing it now.
