Please help: Need to clean osgi cache [message #445457]

Hi Guys, I've asked this question earlier. But maybe I should give a bit
more information. Our RCP application is currently deployed to over 1000
users country wide in south africa. The version does not have the
osgi.clean=true in the config.ini file, or specified in the product program
arguments. So when the application starts, it does not perform the clean
function.

Now, yesterday we wanted to release a new feature, but realized that if the
feature get's deployed, some of the plugin's classes was cached, and when
the application started, it did not pickup the new plugin's classes. What
I've discovered is that if you do a manual -clean, it fixed the problem.

Now i want to know how to programatically clear the osgi cache when the
plugin started. I would have to build this into the application file of my
feature, so that when it starts, it requests a clean. Can anybody shed some
light onto this problem for me? We desperatly need to release this new
feature, and have the osgi cache cleaned when releasing it.

Thanks guys,
Martin Coetzee (South Africa)

Okay, I've noticed that when I delete the 'org.eclipse.osgi' directory from
the 'configuration' directory, everything works fine. Can anybody please
shed some light on this for me? Can I programatically delete this folder
from my application class? I'm starting to get a bit desperate here, we need
to go live into production on thursday...

thanx
Martin

Weird. That shouldn't be happening, especially if your plugins and feature all have their version number upgraded. It would be good if you can recreate the problem and file a bug report on the subject.

That said, there's no way of having a plugin execute a clean sensibly. By the time the plugin is loaded, the system is up and running and you can't really clean it from under its feet. The other problem would be preventing the clean from happening each time your plugin starts; you don't want to do a clean each time.

Bear in mind that a clean is usually a sledgehammer to fix a problem; it may not be necessary (or desirable) to do this. I'd recommend running on a clean install with the version that's deployed in the field, and doing an update with that particular install. It may just be the fact that in developer testing, because they'd been working with the new plugin (1.0.1) that it cached the files from 1.0.1. When the version number changes, the cache should get recomputed. So, as long as your end users are working on 1.0.0, an update will work.

Cleaning the cache is like rebooting a computer. Yes, it will solve your problems but in the most, it's unnecessary, and there will be simpler solutions.

Alex.

You could try posting on the eclipse.technology.equinox newsgroup. The
Equinox project is responsible for the OSGi runtime of Eclipse. I'm not
saying you're off-topic posting here, but there might be more people in
that newsgroup who will have an answer for you.
