When having multiple readers on a PSEPro database, what happens when someone
tries to grab an update lock on it?

What I need to do is have N readers having the database/transaction open
for reading, and every now and then have one writer come in and update some
objects, without disrupting the readers (at least transparent to the
person doing the reading). These readers/writer will need to span
across processes.

Thanks.

In OS5.0 you can open a database in MVCC mode which allows a user to
perform a non-blocking read. I believe this would satisfy your
requirement, I'm not sure whether in exists in the other ObjectStore
products.
