Bundle auto-restart
Hi all,
One small question:
Is there a way in karaf to automatically restart a bundle, if it is in
"Failure" state?
best regards
Aymen

In the console, you could do the following:
*karaf*@root()> feature:install scheduler
*karaf*@root()> schedule --period 1 { each $($.context bundles) { try { $it
start } } }
*karaf*@root()>
After that, every one second, the script will try to start all bundles.

Hi,
Thanks for your feedback & your advice.
I will contact the mailing list (if required) if we run into issues solving the root cause of the problem ourself.
best regards
Aymen

I ran into issues having bundles that bring each other into Failure state during deployment.

The solution is obviously to fix this inside the bundles (Usually OSGi related problems) you are developing.
However, especially on a dev machine it would be nice if there would be an "auto restart if bundle goes into Failure state after x amount of time for n tries". If there is no such option (or if you would say there is no need for that option) that's a valuable and helpful answer for me aswell ;-)

Like a "retry"? What type of temporary failure are you looking to handle gracefully?

I would say you might want to figure out the timing issues and perhaps do
things differently. Are you using blueprint, declarative services, or just
plain OSGi? What is the interdependency? Services?

Yes, like a retry!
I ran into issues having bundles that bring each other into Failure state during deployment.
(If you restart all bundles afterwards it works fine)
The solution is obviously to fix this inside the bundles (Usually OSGi related problems) you are developing.
However, especially on a dev machine it would be nice if there would be an "auto restart if bundle goes into Failure state after x amount of time for n tries". If there is no such option (or if you would say there is no need for that option) that's a valuable and helpful answer for me aswell ;-)

Like a "retry"? What type of temporary failure are you looking to handle gracefully?

Hi,
I guess you mean "automatically" ? Without any action from the user.
Right ?
