[Ace-users] [tao-users] Notification Service: Lifetime of EventChannels

Dear all,

can somebody enlighten me on the concept of EventChannels in the
Notification Service please. 

I can create an EventChannel with the EventChannelFactory but I do not
see any method to delete it. Are EventChannels supposed to live
throughout the lifetime of the Notification Service? 

I am assuming a long living Notification Service, similar to the Naming
Service, with applications starting and stopping. But with the Naming
Service you can rebind() an already existing name. Is an application
supposed to persistently store the channelId and re-use the channels
accross process lifetime? To me this seems to be the only way to prevent
event channel leakage in the notification service.

Thank you for any explanation.
