shutdown framework -> relaunch framework [message #64005]

Hi,

yesterday I played with the OSGI console of my application server. I
think I'm going to use it as the local admin interface. I tried to
shutdown and relaunch the framework but the relaunch did not start the
bundles configured. Then I tried to start the bundles by hand, but all
bundles stayed in resovled state.

Anybody who has an idea why the framework behaves that way?

Regards, Kai

PS: I'm not using the latest equinox bundles.

It is likely that the framework start level is not set to the previous
level. Before shutting down the framework run the "sl" command to see
what the start level is set to. By default this should be 6. When you
shutdown, the framework start level is set to 0. Then when you launch
ii is set to start level 1. You should then set the start level back to
the previous level before you shutdown the framework. Use the "setfwsl"
command to set the framework start level.

Hey Tom,

thanks for your answer. I tried the "setfwsl" with a value of 6 but some
of my installed bundles didn't restart.
I also tried to increment the start level step by step, but this had no
effect.

There are several bundles that are configured with a start level of 2
but not all of them are started by the framework!? Any idea?

Kai

My guess is that the bundles which are not restarted are "lazy start"
bundles. The have either Eclipse-LazyStart: true or Eclipse-AutoStart:
true headers. These types of bundles will not get restarted
automatically until they have a class loaded from them.

hi,

I've just read this and now come up with a similar question. I read an relatively old article "the Eclipse 3.0 platform: adopting osgi technology" which says:

1. "...Eclipse follows a persistent approach; it simply restarts in the same state as that from which it was shut down.".

2. "... the configurator must compare the last-known configuration and the current on-disk configuration, installing or uninstalling bundles accordingly."

Now my experiment:

I start equinox from console:
java -jar startup.jar -noexit -console 3333

now I start a bundle with lazy=false
osgi> start 40

the bundle is activated.

now when I type exit and leave the osgi console I want to reenter and see my bundle with number 40 be activated, but this is not the case. In Felix this just works fine.

the same situation appears, when I uninstall this bundle. the next time I restart the osgi console this bundle is recognized by the configurator and regularly installed. Maybe in the Eclipse IDE the uninstalled Plug-ins/Features are removed from the directory 'plugins'?!?

what is my mistake?

I use the update.configurator and equinox from 3.2M5.

thank you

regards
martin

Did you try to use shutdown, launch and the runlevel commands instead of
exiting the console? IMHO entering "exit" exits the console without
shutting down the framework.

Thanks Kai, I remember the fact, that the console can exit without exiting the framework. With your approach it works, when lazy=false (thanks thomas).
