I've gotten a lot of mileage out of my old SQL Developer Archive Log Count Heat Map report that I created in SQL Developer. I was recently asked to estimate the amount of redo that might be sent to a DataGuard standby. Searching The Google for this and I found some methods for calculating Network Bandwidth but I wanted to start with raw redo generated from an instance using information from v$archived_log.

I was recently asked to update the EBS Plugin from 188.8.131.52.0 to 184.108.40.206.0 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."

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.

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.

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.

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

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

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.

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.
