Just a quick heads-up about some work going on tomorrow on the website.
My hosting provider has decided my server needs to be put into a new rack, so somewhere after 22:00 GMT tomorrow (20th Sept 2015) the server will be switched off, moved to a new rack and switched on. They say the process should be complete within 4 hours. I’m hoping this is a massive overestimate.
In this post, we’re going to use Delphix to create a virtual ASM diskgroup, and provision a clone of the virtual ASM diskgroup to a target system. I call it vASM, which is pronounced “vawesome.” Let’s make it happen.

Most viewers assume Gollum was talking about Shelob the giant spider here, but I have it on good authority that he was (more...)

After more of 14 years of experience working with Oracle Databases of different sizes, levels of activity and critical importance, I know a thing or two about production databases. No matter the size of the database or the complexity of the product that is working with the database, there are always some common settings that DBAs are missing and can adjust improve (more...)
Only two things are really certain: network latency over long distances, and the fact that humanity will soon rapidly degenerate into undead brain-eaters.
When that day comes, when the dead are crowding at your door and the windows are busted out and ripped up rotted arms are clawing at the inside of your home, I know what you’ll be thinking: is my database protected?
Don’t worry, my friends. The Oracle Alchemist has you covered. We (more...)
Last week I attended Oracle OpenWorld 2014, and it was an outstanding event filled with great people, awesome sessions, and a few outstanding notable experiences.
Personally I thought the messaging behind the conference itself wasn’t as amazing and upbeat as OpenWorld 2013, but that’s almost to be expected. Last year there was a ton of buzz around the introduction of Oracle 12c, Big Data was a buzzword that people were totally excited (more...)
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...)
Today’s the first day of school in my city, and the plethora of “OMG 1st day of school!” posts of Facebook and my own kids heading back in to slog through another year of fundamentals got me thinking about education. My own kids (12/daughter and 10/son) came home and went swimming since it was about 104 degrees today…the hottest day of the summer, as it were.
Anyways, after that activity my son decided to (more...)
I'm currently at IOUG Collaborate 2014 in Las Vegas, and I recently finished my 2-hour deep dive into WebCenter. I collected a bunch of tips & tricks in 5 different areas: metadata, contribution, consumption, security, and integrations:
We’ve all got problems. More to the point, every IT department or team has problems of some kind. It’s why we hire consultants, buy products, start long and arduous journeys into the great unknown depths of root cause analysis, and so on.
What fascinates me is the level at which we come to identify with our problems. When I’ve gone into an environment to deliver recommendations, the conversation usually (more...)
We recently has a client with some LDAP performance issues, and had a need to tune how WebLogic was querying their LDAP repository. In WebLogic, the simplest way to do this is with their LDAP Filters. While trying to explain how to do this, I was struck by the lack of clear documentation on what exactly these filters are and why on earth you would need them... The best documentation was in the WebCenter guide(more...)
Three years ago I blogged about the site 99 Bottles of Beer, which is a site dedicated to generating the lyrics of that oh so annoying song in every programming language known... currently over 1500 languages have been submitted. It's a surprisingly useful excercise when learning a new language... (more...)
Another talk I gave at Collaborate 2013 is this one on ADF Mobile and WebCenter. It builds off my talk from last year about general techniques, and gets into specific about the new ADF Mobile technology, and how to integrate it with WebCenter content and WebCenter Portal.
At Collaborate 2013 this year, Tony Field and I put together a talk about a topic that has been been floating around the WebCenter community as of late...How do I integrate WebCenter Sites (Fatwire) with WebCenter Content or Site Studio? We put together a handful of integration techniques, but (more...)
I was recently doing some training on ADF, and the students were complaining how slow JDeveloper was... Dragging and dropping Data Controls onto a JSF page? It's the pause of death if you will. Not to mention the "Out Of Memory" errors that crop up in the middle of debugging a large app. Very frustrating for developers, so I decided to once and for all get figure out what magic JVM tuning parameters would speed it up.
As a general rule, Java is optimized for throughput, not latency. Once the garbage collector kicks in, performance drops like a rock. A (more...)
