Oracle OpenWorld is a time for us to join together and learn all about what Oracle has to offer. But let’s get real, it’s always nice to get free beer. To help show us a good time here in San Francisco, our good friends in the Oracle ADF and Database developer group are planning a Oracle Developers (more...)
At the end of the previous installment we saw that a single big batch delete would (apparently) attach all the “reusable” chunks into a single freepool, and asked the questions:
- Why would the Oracle developer think that this use of one freepool is a good idea ?
- Why might it be a bad idea ?
- What happens when we start inserting more data ?
(Okay, I’ll admit it, the third question is a clue about the answer (more...)
It’s frustrating to have to spend time jumping off into web security and wordpress configurations when there are so many other things that are important to be doing. Today the DoS continued and the Jetpack solution didn’t seem to work. The other two solutions from Digital Ocean didn’t seem reasonable. One was to re-install wordpress with there install version. Nice that they offer a better security protected version but I didn’t feel like re-installing my (more...)
This site had been running for a years with no big issues.
I had performance and system saturation issues about 3 years ago and then move the site to DigitalOcean.com.
They are inexpensive and the performance is awesome.
Then last Monday and every day since the site had been going down.
Simplest “solution” for me was just to get on and bounce the machine.
That cleared it up.
After this went on for a (more...)
Some of my sessions this year at OpenWorld are at the Park Central.
So…you’ve arrived at the Moscone Center, and you’re wondering “How do I get to the Park Central ? After all…that’s where all of the hot talks will be”
Here’s my simple guide:
1) From Howard St, head up the stairs next to the Moscone Center entrance
2) Walk down through Yerba Buena Gardens… You can’t miss them, they are a great grassy (more...)

A coworker passed a test script on to me that was failing with the following memory error:
ORA-04030: out of process memory when trying to allocate 4088 bytes (PLS CGA hp,pdzgM64_New_Link)
The error occurred when initializing a PL/SQL table variable with 7500 objects. Here is my sanitized version of the code:
CREATE OR REPLACE TYPE ARRAY_ELEMENT
n4 NUMBER );
CREATE OR REPLACE TYPE MY_ARRAY
My first OpenWorld was in the Australia in ..well… I’m not sure when but it might have even been the late 1990’s. Time flies.
But 2016 will be my first OpenWorld as an Oracle employee…and hence, I’ll be busy
Hopefully you can come along to some or all of the sessions I’m involved in…or you can probably catch me during the week at the OTN lounge.
I’ll blog more shortly on how I can (more...)

It’s been a while since I’ve published here. You see, I’ve been kind of busy.
Back in January 2015 I was lucky enough to join Oracle as part of their Developer Advocate team. My focus is SQL.
You see I love working with SQL. And I love helping others. So joining the Developer Advocates was a great chance to combine these passions :)
Which leads some to ask:
Why is your site (more...)
I’ve been really busy last few months – except spending a lot of time on M25 I’ve been doing a lot of Exadata installations and consolidations. I haven’t posted for some time now but the good news is that I got many drafts and presentations ideas.
This is a quick post about an issue I had recently. I had to integrate AD authentication over Kerberos on the compute nodes (blog post to follow) but had (more...)
Today I finally finished the Mathematics for Computer Science class that I have worked on since December. For the last year or two I have wanted to do some general Computer Science study in my free time that is not directly related to my work. I documented a lot of this journey in an earlier blog post.
The math class is on MIT’s OpenCourseWare (OCW) web site. It was an undergraduate semester class and I spent about (more...)
Oracle’s Application Container Cloud allows you to run Java SE, Node.js and PHP applications (and more is coming) in a Docker container hosted in the Oracle Public Cloud (OPC). Node.js can crash when applications do strange things. You can think of incorrect error handling, blocking calls or strange memory usage. In order to host Node.js in a manageable, stable and robust way in an enterprise application landscape, certain measures need to be (more...)
I saw this on an AskTom question today answered by my colleague Chris. Check out this simple example
SQL> create table T (
2 x int default 1,
3 y int default 1
4 ,z int);
It looks like I’ve assigned a default of “1” to both X and Y. But lets now dump out the default definition from the dictionary.
SQL> set serverout on
2 longcol varchar2(200);
On the 28th of July, I presented this topic at Kscope16. It was a great conference and if you ever have the chance to visit, definitely do so.
I was reading a very interesting article on Uber’s move from Postgres to MySQL. I really like it when IT professionals and/or companies take the time to explain their technology decisions. It’s a brave thing to do, because it’s easy for people to jump on the bashing bandwagon (“Ha ha … Company X chose Y and now they’re bust” etc etc). It’s the same reason you rarely see detailed customer reference information (more...)
I have been using VMware Player to build test virtual machines on my laptop with an external drive for some time now. I used to use the free VMware Server. My test VMs weren’t fast because of the slow disk drive but they were good enough to run small Linux VMs to evaluate software. I also had one VM to do some C hacking of the game Nethack for fun. I got a lot of good (more...)
This is a blog not related to Oracle products in any way.
This post is specific to apple Airport Extreme and Express wifi routers. However, in general: if you have multiple (unix/linux) servers, it makes sense to centralise the (sys)logging of these servers, in order to get a better overview on what is happening on these servers. I would want to go as far as saying that if you don’t you are simply (more...)
We are excited to announce AuraPlayer has been shortlisted for UKOUG’s 2016/2017
Digital Transformation Partner of the Year! This award provides recognition to Oracle Partners for their contributions to Oracle users by promoting digital transformation.
It has been such an incredible year watching our customer’s applications change from gray screens nailed onto a desktop to cutting-edge mobile applications. Digital transformations have been occurring in all industries including field service, public-sector and retail. We are so (more...)
My kitchen has a very nice range hood over the cooktop. It has a powerful fan and beautiful brushed steel finish. And it has a user experience like most IT systems: Lousy.
Let’s think about what a range hood does. It has two main functions:
- Start the fan to extract grease and fumes
- Turn on the light over the cooktop
Because of the shape of a range hood, the buttons to operate it are typically (more...)
In this video blog, Fishbowl Solutions’ Technical Project Manager, Justin Ames, and Marketing Team Lead, Jason Lamon, discuss Fishbowl’s Agile (like) approach to managing Oracle WebCenter portal projects. Justin shares an overview of what Agile and Scrum mean, how it is applied to portal development, and the customer benefits of applying Agile to an overall portal project.
“This is my first large project being managed with an Agile-like approach, and it has made (more...)
