Alchemists are best known for their (completely fictional and entirely ridiculous, but that’s besides the point) amazing ability to turn lead into gold. Let’s face it, there’s a lot of lead in the Oracle world. Bugs, angry developers, metrics that can seem to elude human understanding…but I (more...)
This year, Rittman Mead were the Analytics Sponsor for the UKOUG Tech13 conference in Manchester, and for those that visited the UKOUG stand during their time there will have noticed the Rittman Mead-sponsored Analytics Dashboard on display. In this blog post I will cover how it was put together, the (more...)
You’ve purchased servers, storage space, switches, cables, and countless other pieces of hardware. The Oracle licenses are bought and paid for, Enterprise Edition with a few add-ons. All told, you’ve spent a small fortune on this infrastructure. It’s finally time to start up your database and begin using it for (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...)
In this blog post, I'm going to demonstrate something that I learned recently during my OIM POC. It's called a custom scheduled task.
OIM or Oracle Identity Manager has several scheduled tasks that you can configure as jobs and make them trigger at specified intervals. However, you also get to (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...)
Given the incredible number of comments I received on my last blog post, and the content of those comments, it is very obvious that folks are extremely confused by what I meant by that post, as well as the comments by Mr. Garsthagen (Oracle Director Level Employee), referenced in that post.
The confusion is typified by the following comment, the most recent I have received:
Oracle does not recognize either (Vmware/DRS Affinity) as a hard partition
First, to be completely clear, I have never stated, nor do I believe, that VMware (or any other software hypervisor for that matter) (more...)
As all of my readers know, I have been a strong proponent of VMware virtualization of Oracle Database servers for license cost savings purposes. Predictably, Oracle has pushed back on this issue in the past. Well, they have now thrown in the towel.
In an online video, Richard Garsthagen, Director of Cloud Business Development EMEA for Oracle, has stated publicly that VMware host affinity rules (when combined with vMotion logging) work just fine, thank you very much, for purposes of establishing where Oracle software is "installed and/or running" for purposes of the Oracle Software License Agreement (OSLA).
As my comment on Michael Webster's recent blog post entitled Fight the FUD – Oracle Licensing and Support on VMware vSphere states, I am in violent agreement with everything he says regarding Oracle licensing and support for VMware virtualization of Oracle database servers. I heartily recommend this blog post to everyone concerned with Oracle's recent behavior regarding VMware virtualization of their products.
I have once again proposed a session at VMworld 2012. This session is titled as follows:
Near Zero Downtime Migration of Oracle Database from Legacy RISC-based UNIX to x86-64 / Linux on VMware vSphere
The reason I believe this session is so important is simple: Every Oracle customer and his dog is desperately trying to get off of expensive, slow, proprietary RISC-based UNIX and onto the x86 environment. The reason for this desperation is simple: Cost. These environments are becoming hideously expensive platforms on which to run Oracle. Huge core counts. And performance is frequently terrible.
For example, EMC IT (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...)
I thought it worth republishing Dave Welch's (of House of Brick) comments to my discussion on the Everything Oracle at EMC online community on the subject of Oracle licensing costs on VMware vSphere configurations. Here are Dave's comments:
Let me start by bringing all of you into the courtroom. There are three issues that you will observe me as counsel provide to the jury as part of my allowed instruction (I am not an attorney in real life).
I offer the definitions in this paragraph only to make this post as self-sufficient as possible and not with intent (more...)
VMware has put a stake in the ground with respect to Oracle licensing of VMware VMs running Oracle. The gist of this statement regarding certification, support, and licensing is that DRS host affinity rules, combined with vCenter audit trails showing where VMs have actually run, are sufficient for Oracle licensing purposes. The summary of the document states:
DRS Host Affinity rules can be used to run Oracle on a subset of the hosts within a cluster. In many cases, customers can use vSphere to achieve substantial licensing savings.
vCenter VMotion Logging
Concerning vCenter VMotion logging, the (more...)
I have received a fair number of responses to my previous post on this subject (some via comments and some via email). I thought the discussion worthwhile enough to punch it up a bit more here.
As I pointed out in the previous post, EMC can easily match NetApp's play to back up ExaData with the following:
As Geoff Rosser so correctly pointed out, this answer is incomplete. Yes, Data Domain is an awesome Oracle backup solution. Yes, it provides incredible deduplication rates for Oracle database environments. (Thanks, dynamox.) However, it is not the only viable solution from (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...)
