Ideally you should open the collections and then use them as long as 
possible. The overhead isn't huge, but it is still there.

If you don't close the collections properly, you'll orphan servant 
instances on the server which is not exactly desirable.

They will hang around until the server is restarted. That is the only 
major resource issue you'll need to worry about.

Kimbro,
I am not as CORBA savvy as I should be, do these orphan servant
instances stay around until the server is stopped and started?   Or
do they time out?   My "client" is a server using Xindice for its
datastore so it is long running, but are their any other resources
I should be careful of?

I think Xindice is a great product, I haven't had a single
problem with it!   I am looking forward to the book!!!
Thanks for taking the time to answer my questions!

Mark
