Cloud Control Error EM-04050 when trying to upgrade a plugin...

I was recently asked to update the EBS Plugin from to in my Cloud Control 12 setup. During the prereq steps I got an error: "EM-04050: The selected plug-ins cannot be deployed on the Management Server because there are some Management Agents on which incompatible versions of these plug-ins have been deployed."

5 in 5 Vizualization 2 - Generating a d3.js visualization from a SQL Developer HTML report...

This second vizualization is more of a workflow proof of concept compared to some novel visualization but I can guarantee you haven't seen the SCOTT.EMP table like this before. I have wanted to combine my two favorite tools for a while. Here is how you can drive a d3.js visualization directly from a SQL Developer custom report.

SQL Developer 4 User Defined Reports

I enjoyed giving my presentation on SQL Developer User Defined Reports to the 2014 East Coast Oracle Users Conference. This is a local conference that is a great value and pulls in lots of fun folks that attend and present. DMann-SQLDeveloper4Reporting.pdf

Check out my GitHub project for examples and source code :

August - Visualization 1 - SQL Execution Plan Volatility

The first visualization I will be working on is something I have been wanting for a while. I need a way to quickly show SQL Statement performance over time for 1 statement, especially to identify Execution Plan volatility. When researching performance problems I often need to quickly digest historical performance of a trouble statement - a statement that usually has run fine for years but now has started acting up.

5 in 5 - 5 Oracle visualizations in 5 months...

It is time for me to get my rear in gear. I have tons of notes floating around on Oracle administration and performance related visualizations I would like to work on but without a deadline things start dragging out... Like when you have a weight loss or stop smoking goal that becomes real when you tell people about it.

Slides and Examples for Time for Some New Graphs...

I gave my talk "Time for Some New Graphs: Incorporating Time and Animation Elements into Your Web App Visualizations" at KScope14 this week. As usual KScope has delivered on content and experts. I have been enjoying immersing myself in the Administration and Apex tracks.
Here are the slides to my presentation : Time For Some New Graphs - Slides

Slides and Scripts for Data Auditing in Oracle

I am currently getting my mind blown by Craig Shallahamer's Oracle Conference on the James presentation on Detailing Oracle CPU Consumption... But earlier today I was able to give my talk on Oracle Data Auditing... Well minus the demos because I need to get better about cutting out slides.

Here are the links to the slides: DataAuditingConceptsAndImplementation.pdf

Live Coding with JavaScript

I have been messing around in JavaScript and d3.js a bit more than usual lately.

In the past my JavaScript prototyping environment was a collection of html/js/json files on my local disk and a basic HTTP server (like python SimpleHTTPServer). I would edit files and reload reload reload reload. Very tiresome. Not very "2014" if you ask me.

Well I have seen the light, there are a few ways to skin this cat and get into a more robust and interactive development environment.

Oracle Flashback Archive Licensing Info...

As the licensing of the Oracle Flashback Features has changed over recent releases I wanted to provide a summary. In 12c Oracle has opened up basic usage of Flashback Data Archive which is a handy way to add data archiving capabilities to existing/legacy applications.
The cost part of Flashback Data Archive is now an Optimization feature which reportedly will reduce the disk space requirements by 2-4 times. This requires an Advanced Compression license to use.

A Delta to Plus/Delta... Good / Tricky / Different...

I have been encountering a lot of Plus/Delta activity at the end of my meetings and projects. Basically it is an informal feedback mechanism. A chance to communicate 1) what was good about the meeting and 2) what may need to be changed in the future.

I can appreciate the sentiment. Just having a project or meeting leader ask for the feedback is a great step forward in improving processes. One of my group leaders took it a step further though when applying it to tasks or projects.
