Clear the data cache for Karaf 2.3.x for a specific bundle

Hello,

I am looking at a requirement which requires me to clear only the karaf
cache for a specific bundle. I know I can clear the entire cache using the
'clean' command on start-up. However, I want the cache for the specific
bundle to be clear while karaf is running. I tried osgi:refresh <bundle_id>
--force, but did not clear out the cache in the data folder. Is there a
command to delete the cache for that specific bundle alone? uninstall and
install command will delete and recreate the cache, however, I want to know
if there is a way to clear the cache without uninstalling a bundle.

Thank you for your time. Any input is greatly appreciated.

Regards,

Asha

Hi,

A refresh does only re-wire the bundle and it's dependencies.
An update will un-install install the bundle.

The refresh without any bundle id will do a rewiring of all bundles.

Thank you Freeman for your response. Just to be clear, I have a few follow-up
questions. I am asking only because I want to understand it better as I am a
newbie to osgi and karaf.
* what is the purpose of osgi-refresh then? I know in the manual its says
that it refreshes the bundle, but I thought it would clear the cache and
reload the bundle. Also when I just type osgi:refresh without providing a
bundle id, will it refresh the entire system?
* if I use uninstall, it clears the cache. Then I do not need to use
osgi:refresh, right?

Once again, thank you for your time.

Regards,

Asha

Hi,

I'd say clear the cache means uninstall that bundle, so the uninstall is the way to go, can't understand why you don't wanna use uninstall
