Ubuntu 10.04 and IBM Data Studio 2.2
IBM Data Studio is an Eclipse based tool to develop databases, sql queries etc. As far as I have understood these and Optim tools should replace the old, Java based Command Center (which you launched with db2cc command).
This Data Studio 2.2 (current version) is downloadable from IBM, and its totally free. Although it is supported only on Red Hat and SuSE platforms, it is possible to install it on Ubuntu, too. Easiest way is to install Data Studio IDE which contains eclipse and other resources. Just unzip the file and
sudo ./setup
in the created directory.
Even if you have eclipse already installed I suggest you choose not to extend it, but install Data Studio’s eclipse separately.
After installation Data Studio will not work without a little tinkering. In this case you have to insert one line into the file /opt/IBM/DS2.2/eclipse.ini. If you are using Data Studio stand-alone version you have to make this insert in the file datastudio.ini.
After line
-Xmx1024m
Add line
-Dorg.eclipse.swt.browser.XULRunnerPath=/usr/lib/xulrunner
Now Data Studio should start normally.

Now it works. Thanks for the tip
thx, this has just saved my night!
I tried to install IBM Data Studio 2.2 on Ubuntu 10.04; when I unzipped the downloaded package, there was no setup file; instead there was an install.bin file. I tried sudo ./install.bin and it gave me this error message:
Preparing to install…
Extracting the installation resources from the installer archive…
Configuring the installer for this system’s environment…
No Java virtual machine could be found from your PATH
environment variable. You must install a VM prior to
running this program.
What should I do?
It still doesn’t work for me…my version is Ubuntu 12.04 and Data Studio v10.1….I added this line into /home/myname/Downloads/eclipse/Data Studioxxx/datastudio.ini and /opt/IBM/DSAC3.1.1/ with root authority but still failed…the datastudio cannot startup, nothing happened while clicking on the executable file…how come….
