Zz Useful Equinox OSGi commands
The original article is in http://isurues.wordpress.com/2009/01/01/useful-equinox-osgi-commands/
Equinox is an implementation of the OSGi R4 core framework specification. This is the OSGi implementation which is used in WSO2 Carbon framework as well. Following commands are extremely useful in troubleshooting OSGi related issues.
ss (Ex: osgi> ss)
This command can be used to list all the existing bundles in the OSGi environment. Bundle ID, State and Bundle symbolic name of all the bundles are shown.
start <bundle-id> (Ex: osgi> start 16)
This command can be used to start a particular bundle. If it can’t be started, reasons are printed on the console.
stop <bundle-id> (Ex: osgi> stop 16)
This command can be used to stop a particular bundle. If it can’t be stopped, reasons are printed on the console.
b <bundle-id> (Ex: osgi> b 16)
This can be used to print all the meta data related to this bundle. That includes imported packages, exported packages, host bundle, required bundles etc.
diag <bundle-id> (Ex: osgi> diag 16)
This can be used to diagnose a particular bundle. It will show you the list of missing imported packages.
headers <bundle-id> (Ex: osgi> headers 16)
This can be used to list the headers for a particular bundle.
packages <package-name> (Ex: osgi> packages org.wso2.foo)
This can be used to list all the bundles which use the given package.
install file:<file-path> (Ex: osgi> install file:/home/temp/bundle1.jar)
This can be used to install a bundle into running OSGi environment. After installing, use ‘start’ command to activate the bundle.
uninstall <bundle-id> (Ex: osgi> uninstall 16)
This can be used to remove a bundle from the OSGi environment.
active (Ex: osgi> active)
This can be used to list all active bundles in the current instance.
refresh (Ex: osgi> refresh)
This can be used to refresh the system. All the package resolutions are refreshed when this is executed. Always refresh the system after uninstalling a bundle as a best practice.
Note : <bundle-symbolic-name> also can be used instead of <bundle-id> in above commands which uses <bundle-id> as a parameter.
