OOW 2012: My Schedule

This will be my third time attending Oracle Open World and I'm really looking forward to the event.It is very hard to make a schedule, there are so many good session available. I thought I'd share my schedule, it might inspire you for your own schedule (or makes it harder to make a choice) and I can look at my schedule without having to login to the schedule builder.
On a side note: Just before landing in San Francisco there was an announcement: "Place your chair in the upright, most uncomfortable position". I thought it was funny, seems like (more...)

APEX: Custom Image on Button Bug

When you use a custom template for your APEX application and you want to use an image on a button, you might encounter a small, trivial bug. Thanks to Anthony Rayner and twitter for a simple workaround.The Setting

For the custom theme that is used in the application that I'm working on, an Application Level Substitution string was created.You can define these substitution strings at the application level, available from the application home page.

In the section "Substitutions" you can create your own substitution string and substitution value pairs. In the screenshot below I created a substitution string (more...)

APEX: Show Actions menu with Authorization

With an Interactive Report you can choose whether you want the Actions Menu to be shown or not. This has to be done by the developer. Of course the customer wanted to have this based upon the existing authorization scheme. How can you solve this? Dynamic Actions to the rescue.
Go to the Interactive Report page where you want to base the Actions Menu upon the existing authorization scheme. And right click on the "Dynamic Action" in the tree view, and choose "Create".
In the wizard that follows choose the "Advanced" option (no screenshot). Provide a name for the Dynamic (more...)

Comparing Schemas: Red Gate Schema Compare for Oracle

This week I attended a webinar by Cary Millsap, organized by Red Gate. It was called "Real Developers DO use Tools" and was focussed on, well, tools. At the end of Cary's talk, James Murtagh showed a demo of their Schema Compare tool. The demo wasn't flawless, but he recovered nicely :) (note to self: don't do live demo's). And this - the demo, not the occuring error - triggered a memory that I wanted to write a blog on the Schema Compare tool.If you missed the webinar you can find it on the website of Red Gate here: (more...)
