Oracle OpenWorld 2012 is just over a month away and yes we are organizing the Annual Oracle Bloggers Meetup — one of your top favorite events of the OpenWorld.
MySQL management plugin for EM 12c has been long overdue. I’ve initially migrated the older plugin to EM 12c about 6 months ago and few dozen people received this as initial beta of the plugin. It worked OK but didn’t use any of the 12c new features and its home page was a bit of a mess in the EM 12c Cloud Control web interface.
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
If you are looking to kick start your community contributions or looking to volunteer more than what you already do, I have an awesome suggestion for you — nominate yourself to serve as an IOUG Oracle RAC SIG Board Officers volunteer. Find out more here.
When preparing for the the IOUG Collaborate 12′s deep dive on deploying Oracle Databases for High Availability, I wanted to provide some feedback on which hardware components are failing most and least frequently. I believe I have a reasonably good idea of the answer, but I thought that providing some more objective data would be better. I couldn’t find results from a more scientific research, so I decided to organize a poll. This blog post shows the results, which I promised to share with several groups.
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 220.127.116.11.1 out that is applied on top of ODA patch bundle 18.104.22.168.0. 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.
