Dusting Off the Data Warehouse

Businesses all over the world have spent millions and millions building data warehouses and implementing Business Intelligence (BI) without coming anywhere near the promised business benefits.

That is about the change.

And the thing that will change this is interactive, visual analytics on tablets.

Tablets and modern interactive graphics are a match made in heaven. Business users who will reluctantly spend half an hour looking at a BI report will happily spend hours playing around (more...)

Exadata Shellshock: IB Switches Vulnerable

Andy Colvin has the lowdown on the Oracle response and fixes for the bash shellshock vulnerability.

However, when I last looked it seemed Oracle had not discussed anything regarding the IB switches being vulnerable.

The IB switches have bash running on them and Oracle have verified the IB switches are indeed vulnerable.

Exadata: What’s Coming

This is based on the presentation Juan Loaiza gave regarding What’s new with Exadata. While a large part of the presentation focussed on what was already available, there are quite a few interesting new features that are coming down the road.

First of was a brief mention of the hardware. I’m less excited about this. The X4 has plenty of the hardware that you could want: CPU, memory and flash. You’d expect some or all (more...)

OOW14 day 0

w00t! One compound word? Mind-boggling!



As a first time OOW participant, when I arrived at Moscone this morning, the sheer size, grandeur and general over-the-top-ness hit me like a brick. Seeing it in pics and on youtube is one thing but experiencing first hand...wow. KScope back in June was a family party in comparison! Which isn't a bad thing by the way

For me, Sunday was all about getting my bearings and participating - (more...)

Time for an Oracle Apex feature request – single sign-on authentication

I've just submitted a feature request because I believe that the current Application Group concept is a fairly weak one if it doesn't bring about some advantage in terms of features for the developer. Basically what I am asking for is that one can easily implement a single sign-on authentication method across multiple applications within the same application group, pretty much like the existing

Oracle OpenWorld 14 Day -1

Saturday was a rather quiet day. After having spent 2 hours on Friday night, trying to get the connectivity working in my hotel room, Friday started out with another almost 2 hours which culminated on a recabling of the room and replacement modem to finally get things working. After that I was able to put the finishing touches to my presentation.

Lunch was...american. Very american. Think 50s-type diner. Think chili-chedder-hot-dog. Think fries. LOVE IT! (more...)

The Hitchhiker’s Guide to the EXPLAIN PLAN: The story so far (Part 11–23)

On the Toad World site, I’m writing a series of blog posts and Wiki articles on the subject of EXPLAIN PLAN. I’m using EXPLAIN PLAN as a motif to teach not just SQL tuning but also relational theory, logical database design, and physical database design. In a year’s time, I hope to have enough material for […]

Openworld 2014

Oracle OpenWorld

Are you going to Oracle OpenWorld 2014? I am, and I hope to see you there! As you probably know, OpenWorld is a humongous event with tens of thousands of people in attendance and some amazing presentations. Why, I even hear Oracle’s new CTO might be there. I wonder if he has anything to talk about?

This year we’ll have a ton of activity at the Delphix booth. You can check out the speaking schedule, (more...)

REQUIRED_MIRROR_FREE_MB

The REQUIRED_MIRROR_FREE_MB and the USABLE_FILE_MB are two very interesting columns in the V$ASM_DISKGROUP[_STAT] view. Oracle Support gets many questions about the meaning of those columns and how the values are calculated. I wanted to write about this, but I realised that I could not do it better than Harald van Breederode, so I asked him for permission to simply reference his write up. He agreed, so please have a look at his excellent post Demystifying (more...)

I Heart Logs – Event Data, Stream Processing, and Data Integration by Jay Kreps; O’Reilly Media

As I have worked in server-side a long time as System Administrator. I must spend with logs. To use it for checking and investigation in issue. As some policies in some Companies, they want to keep logs over year or over ten years. So, it is not unusual to find out idea to store, integrate logs and do something.

The big annual Oracle event is almost here – starting Sunday 28 Sep with the User Group Sunday followed by four days of presentations in around 50 tracks!

If the agenda seems a bit overwhelming, read the OTech Magazine Special OpenWorld Issue to find some of the highlights and can’t-miss sessions.

Oracle OpenWorld’14 Guide!

I think, the biggest challenge for people coming to such huge events as Oracle OpenWorld is to navigate through all of the events that simultaneously happen at various locations. You are always under stress that you may miss something, or that you may hit a bad talk, or that you may not even know that there was a talk directly linked to your key production problems.

Finally there is a real guide to OpenWorld - (more...)

If You Build It, They Still Won’t Come

I’m at Oracle Headquarters for pre-OpenWorld briefings this week, and am seeing many great things (that I’m not allowed to blog about yet ;-)

One thing that still puzzles me is that Oracle still don’t get social. They have very nice Social Network features (their product is called Oracle Social Network), but they insist on keeping this inside a walled garden with no integration to the outside world. In this, they are no different from (more...)

Top 7 Reasons Why Oracle Conferences Rock!


Why take the time and make the effort to attend an Oracle database conference or Oracle user group meeting? We're all busy, so there had better be some super good reasons to make the effort! For me, the benefits definitely exceed the cost.

There are many different conferences to choose from. There are professional (more...)

Why the In-Memory Column Store is not used (I)

yuuupie!

Now finally after a long period of waiting - and looking presentations and reading blogs I was able to do In-Memory databasing on my own. Having sampled some theoretical background how a a pure In-Memory Db works with SAP HANA; my expectations on the Oracle In-Memory Option were high. Also because Oracle promised it would work without code change, out of the box.

The setup

The Oracle database is located on Sun Solaris Machine (more...)
