Is Julies agent FAQ about recycle() still valid in Domino 6 also?
I’ve seen lot’s of session.recycle() being used. FAQ says you don’t have to do that… What exactly are the things we need to recycle? Best practises?
Subject: Java memory and recycle
As far as I’m aware, yes, the advice still stands. The Java object model for Domino comprises classes and interfaces which are “wrappers” to the core C (or is it C++?) code within Notes. This hasn’t changed between R5 and ND6.x, so if you want to avoid memory leaks and what-have-you, you still need to recycle objects.
I’ve seen contradicting opinions with regards recycling the Session object, but given that it has a recycle() method, I’d say it’s required, else why offer it to the developer?
If you’re done with the Session – especially in multi-threaded / connection pooling applications – I say go for it. It can’t hurt.

There are several layers of API’s, but the first level used by the backend classes is C++ wrappers around lower level stuff which is mostly C code.
As for recycle, it’s a good idea to recycle the Session object after you are done with it. This closes down and cleans out your DIIOP connection (if you are using one) and does a few other cleanup tasks if you are using a local Session.
