Second Best Leopard Feature

As I was about to call it a night, I noticed that Leopard had automatically created an icon for "oracle's remote desktop" in the Finder. Double-clicking on it yielded nothing, so I almost just gave up and went to bed. I figured that I'd check the console of my Windows box just in case it was asking for something.

Turns out that the icon is a link to start a VNC session with the Linux VM running on that Windows box. Tweaking the VNC server settings just a spot to allow access without a prompt was all I needed to do. Next time I double-clicked on it, a new window containing the desktop of my Oracle Enterprise Linux VM appeared:

Sure, you can go and configure all of this manually, but it's nice to see this type of "techie" tool seamlessly bundled into a product that is also aimed at complete tech novices.

Custom Export to CSV

It's been a while since I've updated my blog. I've been quite busy lately, and just have not had the time that I used to. We're expecting our 1st child in just a few short weeks now, so most of my free time has been spent learning Lamaze breathing, making the weekly run to Babies R Us, and relocating my office from the larger room upstairs to the smaller one downstairs - which I do happen to like MUCH more than I had anticipated. I have everything I need within a short walk - a bathroom, beer fridge, and 52" HD TV. I only need to go upstairs to eat and sleep now, but alas, this will all change soon... Recently, I was asked if you could change the way Export to CSV in ApEx works. The short answer is, of course, no. But it's not too difficult to "roll your own" CSV export procedure. Why would you want to do this? Well, the customer's requirement was to manipulate some data when the Export link was clicked, and then export it to CSV in a forma...

Manipulating Images with the... Database?

A recent thread on the OTN HTML DB Forum asked about how to determine the width & height of an image stored as a BLOB in an Oracle table. I mentioned in that thread that I have some code to manipulate an image stored in a BLOB column. This is particularly useful if you’re going to let users upload images, and you want to re-size them to display as a thumbnail. Thanks to Oracle interMedia , it is trivial to manipulate the width, height, and other attributes of images stored in an Oracle table. I’ve created a sample application here which demonstrates Oracle interMedia and HTML DB in action. Feel free to have a look. You can download this application from HTML DB Studio as well. Basically, this application allows you to upload images and perform an operation on the image as it is inserted into the PHOTO_CATALOG table. There are two places where some PL/SQL code is required: an After Submit process on page 2, and a procedure to display the images. Here is the PL/SQL for the After...

Refreshing PL/SQL Regions in APEX

If you've been using APEX long enough, you've probably used a PL/SQL Region to render some sort of HTML that the APEX built-in components simply can't handle. Perhaps a complex chart or region that has a lot of custom content and/or layout. While best practices may be to use an APEX component, or if not, build a plugin, we all know that sometimes reality doesn't give us that kind of time or flexibility. While the PL/SQL Region is quite powerful, it still lacks a key feature: the ability to be refreshed by a Dynamic Action. This is true even in APEX 5. Fortunately, there's a simple workaround that only requires a small change to your code: change your procedure to a function and call it from a Classic Report region. In changing your procedure to a function, you'll likely only need to make one type of change: converting and htp.prn calls to instead populate and return a variable at the end of the function. Most, if not all of the rest of the code can rem...
