[omniORB] OmniEvents -- Number of channels?

[Stephen Hansen]

How many channels can omniEvents scale up to reliably? I'm trying to
decide how to set up my system; there are items which belong in
folders, and I want to tell only the people who have those folders
open when its items are changed.

My choices seem to be:
   - 1 Channel per Folder: when a user is interested in a folder they
subscribe to it and get events pushed to them.
   - One channel for all item-update noticies, and then the user drops
any that are for folders that they aren't interested in.
   - Come up with a scheme to group the folders and have a single
channel be for each group.

There will be no more then a couple dozen such update notifications at
any given time, they are almost all caused by user input. I would
rather not have them all stream to everyone, because as the sites
scale up, that's a lot of wasted traffic and processing as irrelevent
messages are discarded.. but I don't know how many channels omniEvents
can scale up to reliably.

Also, I'm having trouble with the persistance feature on windows. I
start omniEvents after my naming server (not actually omniNaming, but
TAO_NT_Naming_Service), and expect the channel I previousely created
to be auto-remad.e. but its not.. how is this susposed to work?

Thanks.
