I am evaulating some schema migration tools for a project I am working on. I want some basic help organizing scads of changes that we will make during development. I also want the ability to produce generic SQL scripts as output to pass along for review / execution by folks that are not knee deep in our development environment.
The SQL Script output requirement cut out a lot of options. For a comprehensive list of options check out the feature matrix on the Flyway page which compares 9 popular schema migration tools.

I posted an example of how to create an Application Express bar graph with the d3.js visualization toolkit in the Notebooks section of the site.
If you want to see how this can be done in Application Express, check out the page here: http://ba6.us/d3js_application_express_basic_dynamic_action .

I added a page to my SQL Developer Tips and Tricks page about integrating the Google Graph API with SQL Developer HTML reports.
I sometimes run out of steam with the built in chart and gauge capabilities of SQL Developer. With a little work you can leverage the Google Graph API to create Line, Bar, Pie Charts, Map, Scatter, Venn Diagrams, Radar Charts, QR Codes and Meters.
Here is everything you need to know to get started: SQL Developer and Google Graph API Example

I have been checking out some usage patterns on a database I am migrating to Exadata. I won't go into the 'drop all of the indexes' herd mentality... but I would like to know what is really being used on this system so we can make some educated guesses about what is really needed. Luckily it is a DW / ETL type of application that has a comprehensive nightly refresh. Yes, a nice way of saying flush and fill. Well at least I know they touch _every_ important object _every_ night.

... or just use SQLPLUS to spool to HTML and open with a browser if you are old school :)
I am on week 4 of my newly reimaged work laptop sans Toad. I am trying to make a go of things with SQL Developer only. So far so good. I have a more comprehensive post on my transition in the works but in the meantime I have been filling in some gaps with User Defined Reports. I started collecting them here: https://github.com/dmann99/SQLDevUDRepPack

I posted my GoldenGate / Gnuplot lag time alerting shell scripts to a new GitHub repository: http://github.com/dmann99/ggtools
The scripts worked on v8 and I don't think the INFO ALL screen has changed much since then so hoping it will work on v11 with a minimum of changes. I will post a more comprehensive walkthrough after I verify the v11 compatibility...
I also have an Alerting perl script that I will be tidying up and including in the ggtools repository ... but that won't be available until later this month.

This is probably old hat for most of my audience but I needed to get this down on paper (or bits actually) for posterity... The granularity of Oracle privileges leaves a lot to be desired...

After lots of wrassling with the Drupal schema we're up and running on Drupal 7.
Sometimes it is a pain to be a DBA. I couldn't just let the problems with the schema upgrade alone and built my own script to fix issues so I could get the upgrade to complete successfully.
You may notice the new layout and color scheme. I will tone things down after I experiment a little bit... But may keep it in order to remind me of the exciting new things I hope to bring you in the coming months. OK I gotta go, the fast food colors in this theme are making me crave a Whopper.

We have many fingers in the pie where I work. Silos, silos everywhere. The DBA Group is responsible for operations and performance. ETL Admins are responsible for data movement. For a number of reasons we cannot allow the ETL Admins to log in directory as Oracle user. This is what I came up with to make everyone happy.
What is an ETL admin?
Our ETL Admins are users who do not need DBA or ROOT type access, they just need to run ggsci, start stop processes, edit config files, and check status of how things run.
