IOUG Collaborate 2013 — Call for Speakers Informational Webinar

As I’ve become Director of Communities for IOUG recently, I’m intimately involved in many aspects of leading the IOUG community. One of the areas the user group is pursuing all the time is finding new speakers, and it takes a lot of convincing before community members actually start presenting. There are many of you who have exciting projects and implementations to share but can’t quite convince themselves to actually present.

Hardware Component Failures – Survey Results

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.

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 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.
