Extensions to the Specification
Gemini Management extends the JMX Specification Version 1.0 interface
BundleStateMBean with a method
TabularData listBundles(int mask).
The original interface has the same method, but without arguments. It returns a
TabularData object, containing all details for all bundles. The new method
allows to specify (through the mask) what details to be present in the result. For example, in this way only the ids of all bundles could be retrieved, without any
other details. In the case of a system with a large number of bundles this could considerably improve the performance since much less data is transferred through the
Gemini Management also extends the
ServiceStateMBean with methods for introspection of a single service:
CompositeData getService(long serviceId)- get service by its id
CompositeData getProperty(long serviceId, String key)- get the value of a property of a particular service
TabularData listServices(String clazz, String filter)- get all services implementing an interface and satisfying a filter
TabularData listServices(String clazz, String filter, String... serviceTypeItems)- get all services implementing an interface, satisfying a filter and specifying particular properties
long getServiceIds()- get a list of all service ids
Both extensions are included in the next version 4.3 of the Enterprise Specification.
