A few more 12c articles

A few more 12c articles went live over the last few days…

The DMU and In-Database Archiving are from the OCP syllabus. The Invisible Columns stuff seemed like a natural thing to mention, when discussing the In-Database Archiving.

The 12c journey continues…

Cheers

In-memory Consistency

A comment on one of my early blogs about the 12c in-memory database option asked how Oracle would deal with read-consistency. I came up with a couple of comments outlining the sort of thing I would look for in a solution, and this note is an outline on how I started to tackle the question – with a couple of the subsequent observations. The data is (nearly) the same as the data I generated for my previous article on the in-memory database (and I’m running 12.1.0.2, of course):

Oracle performance video library

Here is a series of Oracle performance tuning videos that I put together recently at Delphix. All the presentations are free and open to the public, just have to register.

Greening of Storage

By Tim Gorman

I’ve Got A Ram

Just in case anyone thinks I might lack the passion to make happen what I say I will make happen (end domestic poverty and the war on drugs together with all its bad effects, for starters), here is this link to my youtube channel and a song I sang for the Bel Canto benefit concert (sorry in advance for the poor video focus. The sound should be okay).

You can also see me directing the University Chorus of the Upper Valley and plenty of other things on my channel pudge1954.

Enjoy.

The Next Big Thing

Oracle’s 12.1.0.2 was released a few weeks ago (You can download it from OTN here: Oracle 12.1.0.2 Download). While technically a minor point release, it contains a couple of major features that would normally be rolled out in a more substantial version change like 12cR2 or perhaps V13. Of course the most highly anticipated feature is a new option (Oracle In-Memory Option) that provides a column oriented, in-memory store. Enkitec was in the Beta program, so we’ve been testing it out for quite a while now and we are impressed.

OTN APAC Tour 2014

As well as losing the ACED OpenWorld confirmation email, it turns out my website/mailbox move also caused me to lose the email about being accepted on the OTN APAC Tour 2014. I saw a tweet this morning saying that I was on the agenda for the NZOUG event and checked with Francisco to see what was going on. That’s when I found out that yet another important email had gone missing… :)

The good news is I had already agreed the time off work, so everything is good for the tour.

12.1.0.2 Introduction to Attribute Clustering (The Division Bell)

One of the really cool new features introduced in 12.1.0.2 is Attribute Clustering. This new table based attribute allows you to very easily cluster data in close physical proximity based on the content of specific columns. As I’ve discussed many times, indexes love table data that is physically clustered in a similar manner to the index … … Continue reading
