You can start eXtreme Scale servers
and clients in an OSGi container, which allows you to dynamically
add and update eXtreme Scale plug-ins to the runtime environment.
Building eXtreme Scale dynamic plug-ins WebSphere® eXtreme Scale includes ObjectGrid and BackingMap plug-ins.
These plug-ins are implemented in Java and
are configured using the ObjectGrid descriptor XML file. To create
a dynamic plug-in that can be dynamically upgraded, they need to be
aware of ObjectGrid and BackingMap life
cycle events because they might need to complete some actions during
an update. Enhancing a plug-in bundle with life cycle callback methods,
event listeners, or both allows the plug-in to complete those actions
at the appropriate times.
