Which is the Most Common DB?

This is an interesting question that I sometimes find myself thinking about. I’ll start with my answer, I actually don’t know, but I can show you that all them can be! Since my wife is doing a Ph.D. in biology she reads and analyzes a lot of data and also decides how to present it […]

GDC Day 3: Another day of fun & data!

Early morning view of the GDC16 Expo Hall.

The Expo opened today and will be open until the end of Friday! There was a lot to see and do! I managed to explore 1/3 of the space. Walking in, we have the GDC Store to the left and the main floor below the stairs. Upon entering the main floor, Unity was smack dab in the center. It had an impressive set up, but not as (more...)

GDC Day 2: Highlights & Trends

Just like yesterday, the VR sessions were very popular. Even with the change to bigger rooms, lines for popular VR talks would start at least 20min before the session started. The longest line I was in snaked up and down the hallway at least 4 times. The wait was well worth it though!

Today was packed. Many sessions overlapped one another. Wish I could have cloned 3 of myself :(

Throughout each session, I noticed points (more...)

GDC Day 1: Daily Round Up

Hello everyone! I wrapped up the first day at the Games Developers Conference (GDC) in San Francisco! It’s the first Monday after daylight savings so a morning cup of joe in Moscone West was a welcomed sight!

First Thoughts

Wow! All of the VR sessions were very popular and crowded. In the morning, I was seated in the overflow room for the HTC Vive session. Attendees were lucky to be able to go to 2 (more...)

Oracle VTS Continues…

If you don’t know, Oracle VTS is presented 3 times for three different parts of the world. The first VTS was on March 8th for the Americas (9:30am Pacific Time) and I loved it. I left about 20 minutes for Q&A, which is quite a lot and still didn’t manage to answer all the questions! […]

The Anki Overdrive Car Project

At the end of 2015, our team was wrapping up projects that would be shown at the main Oracle conference, Oracle OpenWorld.

As with every OOW, we like to come up with a fun project that shows attendees our spirit of innovation by building cool projects within Oracle.

The team was thinking about building something cool with kids’ racetracks. We all were collectively in charge of looking for alternatives, so we visited a toy store to get ideas and see products that already existed out there.

“That Ain’t Right”


"Is everyone who lives in Ignorance like you?" asked Milo.
"Much worse," he said longingly. "But I don't live here. I'm from a place very far away called Context."

Dates are, well, dates. They are not strings, they are not numbers, they are dates and to handle them properly the correct data type needs to be used. I can’t count how many times I’ve seen dates stored (more...)

Heap Of Trouble


"But I suppose there's a lot to see everywhere, if only you keep your eyes open."
-- Norton Juster, The Phantom Tollbooth 

Oracle Support recently updated what I call a ‘blast from the past’; it involves a subpool memory leak in Oracle 11.2.0.1 and shared cursors. Originally submitted in 2010 this issue was updated the end of last year to reflect the status of ‘Fixed in Product Version 12.1’. There (more...)

Why GUI sucks…

Of course we all know GUI stands for Graphical User Interface, just as CLI stands for Command Line Interface, right!
Or, rather, a GUI is this nice, flashy screen where you can easily roam with your mouse, comparable to a multiple choice quiz, where the right answer is there for the picking.
A CLI on the other hand is this dark, mysterious blinking cursor… Nothing happens unless you know more or less what (more...)

“Say What?!?!?”


"The only thing you can do easily is be wrong, and that's hardly worth the effort."

Oracle can lie to you. Not like a disreputable uwed-car salesman but more like the ‘little white lie’ sometimes told in order to hide less-than-desirable parts of the truth. And it’s not Oracle, really, it’s the optimizer and it does it by reporting query plans that may not accurtely report the execution path. (more...)

Export-Import Business


"Don't you know anything at all about numbers?"

"Well, I don't think they're very important," snapped Milo, too embarrassed to admit the truth.

"NOT IMPORTANT!" roared the Dodecahedron, turning red with fury. "Could you have tea for two without
the two -- or three blind mice without the three? Would there be four corners of the earth if there
weren't a four? And how would you sail the seven seas without a seven? (more...)

Sangam 15

This was my 6th year at Sangam and as always was good fun. We were a group of 4 people who were traveling from Delhi and we reached Hyderabad on Friday morning. Just wanted to keep a day for visiting Ramoji Film City and also wanted to avoid the rush that morning travel on the conference’s starting day brings. So after dropping the luggage at the hotel we hired a taxi and reached Ramoji Film City. (more...)

DBA_FEATURE_USAGE_STATISTICS and SE2

This blog post is inspired on work I have been doing on Standard Edition databases and the returning confusion about what is and what is not part of Standard Edition.

DBA_FEATURE_USAGE_STATISTICS is a tool in determining license usage for the Oracle database. It is good to understand the implications of each entry, know what is happening in your database and thus be able to have a substantial conversation about the usage of your license, being (more...)

You’re On A Roll(back)


"I know one thing for certain; it is much harder to tell whether you are lost than whether 
you were lost, for, on many occasions, where you are going is exactly where you are. On 
the other hand, if you often find that where you've been is not at all where you should have 
gone, and, since it's much more difficult to find your way back from someplace you've never 
left, I suggest you go  (more...)

Results, What Results?


"For instance," said the boy again, "if Christmas trees were people and people were Christmas trees,
we'd all be chopped down, put up in the living room, and covered in tinsel, while the trees opened our presents."
"What does that have to do with it?" asked Milo.
"Nothing at all," he answered, "but it's an interesting possibility, don't you think?"

Hakan You Do That?


"Everyone understands numbers. No matter what language you speak,
they always mean the same thing. A seven is a seven anywhere in the world." 
Norton Juster, The Phantom Tollbooth 

An interesting problem submitted to Oracle Support involves a possibly little-known aspect of a table called the Hakan Factor. The problem description, in brief, states that the Hakan Factor isn’t preserved for a partitioned table when a single partition is compressed. Why is this a (more...)

The rising of the Standard Edition (#orclse2)

It was the second half of 2011 when the broader introduction of Standard Edition database security tooling was introduced in The Benelux. Dbvisit Standby was the tool and protecting data in Standard Edition databases was the deal.

I remember the first meetings vividly! The Standard Edition database? Many people had not heard of this edition or, more frighteningly, the ones that knew about it, ignored it. Standard Edition was not something to be taken seriously, (more...)
