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...)
I was never really a fan of mobile applications: I prefer the mobile web experience. Every mobile device supports HTML5, which means that you can do just about everything a mobile app can do, other than high-performance graphics. In fact, according to an Adobe study users prefer mobile web to mobile apps for just about everything.
Oracle recently acquired FatWire, and renamed it WebCenter Sites. It is a "web experience management" toolkit, which is similar to Oracle's existing Site Studio product -- a part of Oracle UCM, now called WebCenter Content.
After using Site Studio for years, I got pretty accustomed to it's terminology and toolkits... so looking at FatWire was initially intimidating because it was just so dang different. But, after using it for several months, I've come to the conclusion that a lot of the fundamentals are pretty similar. Pretty much everything Site Studio does is built in to FatWire, and FatWire has a (more...)
Oracle UCM Patch Set 5 is released! And thus begins the long, long hunt for the patches you need to upgrade...
Most of this info is available in the Oracle FAQ for ECM 11g, as well as the Oracle Fusion Middleware Patching Guide... but I was tired of it being un-googleable... So I decided to put a few of the links together here.
Upgrading ECM can be a multi-step process. You need to upgrade WebLogic before upgrading ECM, and you need to make sure you have the right version of the Repository Creation Utility (RCU)... not to mention the (more...)
How many times has this happened to you???
You're looking around Oracle for the latest patches, and after copious amounts of digging, you finally find the mystery patch that you need... you click on the "download" link, install it, and you're good to go!
Later on... your client, or co-worker, or somebody on the message board asks, "How'd you do that?" And because you have a photographic memory, you reply "With patch 12395560, of course!" Then they ask, "got a link?" And then you say this:
