Unable to delete uninstalled bundle from filesystem. [message #1739802] Thu, 04 August 2016 14:37 Go to next message

Hi,

I need to remove a jar file in a running system from a bundle that has been uninstalled, but Windows (server 2008) keeps telling me that the file is still open. I have uninstalled all but the framework bundles to make sure I wasn't holding on to anything, but it seems that the framework itself is holding on to it.

Is this a known issue? The framework we are using (3.9.1) is a tad (...) dated, so it may have been resolved in newer versions. I can't find anything about it though.

The challenge is that this makes it hard to update a bundle in a live system, because when we restart we get the old version back. I guess the only solution to this is to manually muck with the config.ini file and add the version there?

Any insight is appreciated.

These are the remaining bundles, and still unable to delete the file.

id State Bundle
0 ACTIVE org.eclipse.osgi_3.9.1.v20130814-1242
1 ACTIVE org.apache.felix.gogo.command_0.10.0
2 ACTIVE org.apache.felix.gogo.runtime_0.10.0
3 ACTIVE org.apache.felix.gogo.shell_0.10.0
4 ACTIVE org.eclipse.equinox.console_1.0.100.v20130429-0953


Kind Regards,

Erwin

After uninstalling the bundles did you do a refresh operation? From the console that is simple running the 'refresh' command. It can also be done using:

https://osgi.org/javadoc/r5/core/org/osgi/framework/wiring/FrameworkWiring.html#refreshBundles(java.util.Collection,%20org.osgi.framework.FrameworkListener...)

or

https://osgi.org/javadoc/r5/core/org/osgi/service/packageadmin/PackageAdmin.html#refreshPackages(org.osgi.framework.Bundle[])

It is possible that the bundles are still being held as stale removal pending bundles by the framework.

Thomas,

Thanks for your reply.

Yes, I ment to mention that in the original post, I did a refresh after every bundle uninstall.

The complete framework has around 130 bundles, so I uninstalled around 125.

Turns out that this is a foot-in-mouth.

When executing a bundle uninstall w/o first stopping the bundle, an exception is thrown, which prevents some resources from being dereferenced. If the bundle is stopped before uninstalling everything is just fine. Duh.

Apologies for wasting your time.

Erwin

Strange thing is uninstalling a bundle must stop the bundle first. So there should a requirement to stop it first. But perhaps stopping all bundles involved is allowing the uninstall and refresh to work. But still seems like something fishy is going on.
