Analogy

So 12.1.0.2 is out with a number of interesting new features, of which the most noisily touted is the “in-memory columnar storage” feature. As ever the key to making best use of a feature is to have an intuitive grasp of what it gives you, and it’s often the case that a good analogy helps you reach that level of understanding; so here’s the first thought I had about the feature during one of the briefing days run by Maria Colgan.

“In-memory columnar storage gives you bitmap indexes on OLTP systems without the usual disastrous locking side effects.”

Oracle Licensing : It’s Your Responsibility to Comply

This little moan was inspired by a couple of posts by Kevin Closson.

Kevin is awesome (I love you Kevin!), but I don’t happen to agree with him in this specific case. Having said that, I do understand where he is coming from.

Oracle Database 12c Release 12.1.0.2 – My First Observations. Licensed Features Usage Concerns – Part II.

Preface

In this post you’ll see that I provide an scenario of accidental paid-feature “use.”  The key elements of the scenario are: 1) I enabled the feature (by “accident”) but 2) I didn’t actually use the feature because I neither created nor altered any tables.

In-Memory Column Store and More

It was inevitable that I would have to have a play with the In-Memory Column Store.

It’s just a functional look. I have no idea about performance at the moment, although I should be starting a proof of concept in the next couple of weeks for one of our internal systems, so it will be interesting to see how it holds up. :)

Another thing that has come out of this release is the Full Database Cache Mode. That’s nothing to do with the In-Memory Column Store, but I can definitely see us using this on some of our stuff!

AWR Warehouse, Status

So the AWR Warehouse patches are out, but documentation has not officially caught up to it yet, so as we appreciate your patience.  I thought I would post about what I went over in my webinar last week when I had the wonderful opportunity to speak to the ODTUG members on this feature that everyone is so anxious to get their hands on.

Let’s start with some of the top questions:

Oracle Database 12c Release 12.1.0.2 – My First Observations. Licensed Features Usage Concerns – Part I.

My very first words on Oracle Database 12c Release 12.1.0.2 can be summed up in a single quotable quote:

This release is hugely important.

I’ve received a lot of email from folks asking me to comment on the freshly released In-Memory Database Option. These words are so overused. This post, however, is about much more than word games. Please read on…

When querying the dba_feature_usage_statistics view the option is known as “In-Memory Column Store.”  On the other hand, I’ve read a paper on oracle.com that refers to it as the “In-Memory Option” as per this screen shot:
