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...)
Some days before ZeroTurnaround has released XRebel , a new tool to recognized problems in your web applications, when you make your developer test.
This was promising, so I give it a short try for Oracle ADF applications. For this blog I use the Summit ADF application, delivered by Oracle, but I have tried with our own application too. Test is done in JDeveloper 12.1.2.
After the download there are some easy steps (more...)
If you speak german and you are interested in quality assurance for your ADF projects you should come and attend my presentation at DOAG Development on 06/04/2014 in Dusseldorf.
I will show you, how you can implement in the JDeveloper IDE and in Continous Integration server Jenkins:
- static code analysis with PMD, FindBugs and Checkstyle
- Commit tests with JUnit, Mockito and Powermock for Mockito
- Code coverage for commit tests with JaCoCo
- Acceptance tests with JUnit (more...)
Back in March of last year I wrote an article on the five frequently misused metrics in Oracle: These Aren’t the Metrics You’re Looking For.
To sum up, my five picks for the most misused metrics were:
- db file scattered read – Scattered reads aren’t always full table scans, and they’re certainly not always bad.
- Parse to Execute Ratio – This is not a metric that shows how often you’re hard parsing, no matter how (more...)
Random thoughts on a Friday afternoon…
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...)
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...)
Funny thing I had today. Well funny, not when you want to make progress in your work, but still interesting what I discovered when I tried to isolate the problem…I found a way to make the same mistake and have Oracle return three different errors, dependent on the order of (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...)
Thank you all who attended my sessions at NYOUG Fall Conference this morning. I appreciate spending you most precious commodity - your time
- with me. I sincerely hope you found both the presentations enlightening as well as entertaining.
Please see the details of the sessions below along with the (more...)
Not too sure what I changed on my laptop, possibly just installation of another product or perhaps Microsoft or similar updates, but when I went to edit a BI Publisher RTF template I got the following error message on clicking ANY button in the BI Publisher plugin for Microsoft Word.

Version control is a USB stick and a guy named Sahib
It has been too long since the last post. It is not that I do not want to, it is just way too busy…
I just came across a small problem where a .NET application written by someone else caused an ugly Stack trace with a ORA-942 (Table or View does not exist) after being moved to the next environment. The error was not there on development, so they asked me what the problem could be. At first I did my compare of grants to the Role I am supposed to use for the application. The problem is (more...)

And that's a compliment!
Wow. This year we mark the 20th anniversary of the Visual Basic 3.0
launch way back in 1993.
It's easy to forget the pivotal role it played in revolutionizing how we built software. No matter what you think of Microsoft, one can't deny the impact it had at the time. Along with other products such as PowerBuilder
and Borland Delphi
, we started to see long-promised advances in software development (as pioneered by Smalltalk
) become mainstream reality:

ORA-31011: XML parsing failed

In the Oracle E-Business Suite (EBS) Release 12 the data model of Suppliers has become much more complex. The base tables have changed (Suppliers, Sites, Bank Accounts, Contacts) and some of the fields have become obsolete.
Here is a query to bring many of the Supplier attributes together, with focus on banks / bank accounts, payment methods, contacts, remittance delivery (email, notification method). Please post comments if you find any issues!
Adjust the WHERE clause on the first WITH query to return the suppliers that you need to report on. Hope this query helps someone out.
Add additional fields to (more...)
I often get asked to take a look at an Oracle eBusiness Suite concurrent request to see what it is doing, this can come from a few different angles:
- What requests are currently running?
- I have an operating system process that is taking too much CPU - what is it doing?
- Can you tell me where the request is at? I've clicked on the log but it doesn't show anything!
- My request is taking too long - can you check for blocking locks?
There are a number of strategies to track and trace where things are at for a running (more...)
How to deal with DBMS_RLS?
These last weeks I am trying to get the VPD option (Virtual Private Database) enabled for my application. This time as a developer with no DBA or SYS privileges. I am used to being a DBA for the databases I work on and am used to being able to get the fullest out of the Oracle database. For one, because I think Oracle provides us with a great deal of built-in features that do things more efficiently than we can do ourselves (more efficient, built-in kernel code) and also especially because it seems useless (more...)
