Data Tools at EclipseCon 2009

Hey all!

Yes, the holidays are almost upon us... But even better than that, EclipseCon 2009 is just around the corner! (Ok, maybe not RIGHT around the corner, but three months will zip by in no time.)

This year in the Data Tools track we have a tutorial coming up and bunch of cool talks from a number of different directions.

Though I'm helping with the tutorial this year and moderating a block of short talks, I also am talking about how to use DTP to connect to something other than a database. After all, not all data is in databases!

My long talk this year will show how DTP and the Data Source Explorer can be used for searching and viewing YouTube videos in Eclipse. How do these two worlds meet? Come to my talk and find out!

Besides that, I get to moderate a set of three cool short talks. These bright folks will talk about how DTP is being used in RCP as a database developer's type of tool, what's going on with the SQL Query Builder in Galileo, and how DTP is being used in cool ways by a commercial application.

So be sure to check out some of our talks this year! In another post, I'll talk some about what to expect from our tutorial and some of the other cool talks going on at EC2009 that I'm excited about!

Register today and don't forget to reserve a room at the hotel (it fills up fast!)!

Happy Holidays to all!

Out of Memory Errors...

True-color image taken by the Galileo probeImage via WikipediaHi all...

I recently spent about a day and a half chasing my tail trying to track down some bizarre out of memory errors I was running into with Ganymede SR1 when debugging some DTP stuff and thought I'd pass along what I learned. I was continually running out of heap space while debugging, which was very troubling.

At first, I thought I had somehow corrupted my workspace. So I created a new workspace and tried it again (several times actually) and ended up with the same problem.

Next, I thought I'd try the Galileo Platform Galileo M3 build (along with the associated GEF, EMF, and DTP builds) and see if I got the error. At first I didn't, and I thought 3.5 might have fixed the problem... [sigh] No luck.

So then I started poking around on Google, trying to figure out how to bump up my heap space.

I kept running across this suggestion (which after thinking about it was kind a "well duh" kind of thing):
"Add -Xms256M -Xmx512M to the VM arguments for the runtime configuration or on the main Eclipse command line when you start it up..."

Lo and behold it works now in Galileo and Ganymede. Life is good.

But it was a frustrating end to the week, only to discover that I was just oblivious to the simple solution. :(

Hope this saves someone else from the pain and suffering!

New DB Support in DTP for Galileo...

The :en:SQLite logo as of 2007-12-15Image via WikipediaHey All!

Yes, it's been a while. But things are starting to hop with DTP for Galileo.

Our DTP 1.7 release will include some support for new databases and some updated support for existing ones...
  • Ingres has been kind enough to contribute their plug-ins for Ingres DB support in DTP for Galileo and we finally have them as part of our regular build.
  • I added some rudimentary SQLite support recently and that's now part of the regular build.
  • And Ivar and our friends at NexB were kind enough to contribute some big updates to our Microsoft SQL Server support, including new support for SQL Server 2008.
So big thanks to Ingres and NexB for making those contributions possible!

More changes are going in all the time as well... Enhancements and bug fixes mostly, but some new features as well.

Be sure to check out our M4 milestone build here for some early access!
