Rittman Mead has always had a long standing commitment to giving back, not only to the technology industry, but to local and global communities as well. Recently, Rittman Mead employees have been encouraged to take up to 40 paid hours to participate in community service opportunities. This year, I chose to use my 40 hours to serve at an orphanage in the Dong Nai province of Vietnam. The Bien Hoa Center for Supporting and Vocational (more...)
Last week my kids’ school went on a field trip to the University of Santa Cruz to observe a black hole multimedia exhibition. We were invited there by Enrico Ramirez-Ruiz, the astrophysicist and the fellow parent at the school. When Enrico is not busy pushing the frontiers of science (he is impartial to violent explosions), he teaches astrophysics to children age 4 to 12.
The exhibition combined the visualized data from recent Extreme Mass (more...)
#DOAG2016, the largest Oracle Community gathering in Europe. Taking place in Nuremberg, at the Nuremberg Convention Center NCC, one of the more impressive places to hold such a conference, towering 4 stories high, with a big central atrium!!
It is a huge effort to get all of this together!
In this blog-post I want to highlight some of the crazy things I experienced this week… And… I did try to follow my own schedule (more...)
eDB360 provides a lot of insight about an Oracle database. It executes thousands of SQL statements querying GV$ and DBA views from the Oracle’s data dictionary. It was designed to impose very little load on the system where it executes, thus it consumes only one session and avoids parallel execution. On a system where the state of historical metrics is “normal”, eDB360 may take one or two hours to execute. In the other hand, when the (more...)

In one of the Oracle forums a question was asked regarding revoking selected privileges from the DBA role. Unfortunately for the person posting the question the answer is a resounding “No”; granting a role grants all privileges assigned to that role and there is no “picking and (more...)

In a recent post to an Oracle forum a query was presented and a tuning request was made. It appears that the query was taking 20 hours to complete. Through further interrogation and responses it was discovered that the dates were being stored in a VARCHAR2 column and implicit date conversion was being used. To show how much (more...)
"Let me try once more," Milo said in an effort to explain. "In other words--"
"You mean you have other words?" cried the bird happily. "Well, by all means,
use them. You're certainly not doing very well with the ones you have now."

A recent question in the Oracle database forums has a user wanting to open his physical standby database in READ WRITE mode but still (more...)
When tech media started proclaiming 2016 as the year of the bots, they seem to have nailed it. At Oracle we have at least three groups working on bots, OAUX included.
One of the latest forays into bots was a Personal Assistant Technologies (PAT) hackathon, organized by Laurie Pattison’s (@lsptahoe) Apps UX Innovation Events team, open to people across Oracle. The goal? Create a great use case for bots with a great (more...)
I have been always intrigued by the fact that people get deeply attached to the characters in the game (e.g. Second Life), or virtual pets. And with sufficient advancement in technology, the virtual characters may eventually cross the boundary and get attached to real-life people (e.g. Sci-Fi movie such as “Her”). While that is still a little far away from now, I’ve been looking to explore the 2-way communication and interaction between virtual (more...)

With every new release Oracle provides new features that are very useful, even if you didn’t think of them before. In 126.96.36.199 Oracle provides a new functionality for finding pattern matches in a data set; using the MATCH_RECOGNIZE function it’s fairly easy to generate results based on a defined pattern in the (more...)
This was a strange one. Attempts at recompiling the following package body resulted in this PLS-00801 error. COL owner FOR A20 COL object_name FOR A40 BREAK ON object_name SELECT owner, object_name, object_type, status, created, last_ddl_time FROM dba_objects WHERE object_name = 'PKG_FINANCIALS_WORK' ORDER BY status, object_type / OWNER OBJECT_NAME
This is part 2 of my blog post series about the Ambient Visualization hardware (part 1). Also, please read John’s post on details about the creation of the actual visualization, from concept to build. In the first part, I focused on the hardware, a sonar sensor connected to a NodeMCU. In this second part, the focal point will be the software.
When I started working with ESPs a few years ago I was all (more...)
As John mentioned in his post, one of the projects I worked on for OOW16 was the devices to provide the data to his Ambient Display. Unlike previous years, where we record attendance and then produce a report a few days or weeks after OOW, Jake proposed that we’d somehow visualize the data in real-time and show it to the attendees as they are producing the data themselves.
In order to produce the data, we wanted to strategically (more...)
This year I had the great opportunity to attend in person Oracle OpenWorld 2016 and JavaOne 2016. Since I was student, I heard how fantastic and big is this conference but you cannot realize it until you are in it.
All San Francisco is taken by a bunch of personalities from all companies around the world, and it’s a great space to talk about Oracle, show off our projects and of course, our vision as (more...)
Today, October 11, 2016, is OTN Appreciation Day. In honor of that I wanted to post my favorite offering from Oracle — Exadata. Yes, I’m biased but even at that the Exadata platform is an outstanding offering from Oracle. Let’s look at some of the ways Exadata provides performance and value.
Exadata is an engineered system, meaning that all of the components are selected and configured to work together to provide performance. Part of that (more...)
We are posting these blog posts today as part of the OTN Appreciation Day, a celebration for the Oracle Technology Network as suggested by Tim Hall, inspired by Debra Lilley.
The mission was not too hard: write about your favorite bit of Oracle Technology.
As a developer and a core-tech DBA and APEX enthusiast… the choice was easy! PL/SQL (apart from how it is pronounced or even written ;-)!
Not just because (more...)
OK, it wasn’t me exactly. It was more like some of my software-based representatives.
Hi, I’m Ed (@edhjones). And I’m not one of the AppsLab folks. But I’m always interested in the work they do, so I try to hang out with them whenever we’re co-located. I was intrigued then when, a couple of months prior to OOW16, I get a mail from Jake (@jkuramot) CC’ing Raymond (@yuhuaxie). It (more...)

We have been quietly observing and evaluating our options before we finally decided to get a telepresence robot. Telepresence technology dates back to 1993 (Human Productivity Lab) and telepresence robots are not completely new.
There is a growing array of telepresence robot options (see comparison) and the list is bound to get cheaper and better. Before we settled on getting the Double Robotics robot, we tested the Suitable (more...)
In this post I just wanted to highlight a few things that have lingered with me since the 2016 Oracle Open World Experience.
Now, here, being at home, I must admit that I cannot find very much documentation about this, but it got me thinking… A little paradigm-shift, where computers actually wouldn’t need moving parts anymore (ie. disks of any kind). Create devices that use these memory structures, quite possibly combined with flash-disks, (more...)
One month before we entered the Exchange Tent at OpenWorld, Jake challenged us to come up with a visualization “that would ambiently show data about the people in the space.”
A view of the Apps UX Exchange Tent at OpenWorld 2016
Mark and Noel and I accepted the challenge. Mark put together the Internet of Things ultrasonic sensors, Noel created a cloud database to house the data, and it fell to me to (more...)
