How to detect root subsystem available

[Paul F Fraser <pa...@a2zliving.com>]

Hi,

If I have a bundle to manage subsystem install, starts etc. in code rather than use subsystem gogo 
command manually, how can I detect that the root subsystem creation is completed?

I have created a subsystem manager (ds) bundle using code similar to that in the subsystem gogo bundle.

My system uses java service wrapper to run as a service.
If I restart the system (jvm) the synthesized bundle is not available until after the subsystem 
manager has been activated.
How should I approach waiting for the root subsystem?

Also, the bug reports relating to restarting subsystems after the jvm has been stopped are still open.
Has this situation been handled yet?

Thanks,

Paul Fraser

Hi John,

Thanks for your reply.
The JVM crash case is of interest and I will look forward to a future resolution of the problem.

Look for a root subsystem state of ACTIVE while monitoring service events.

Which bugs are you referring to? The only one I'm aware of is for JVM
crashes, and it has not yet been addressed.
