Hi Floyd,
I know for Weblogic server, only one bean instance of a unique primary key
may exist; however there may be multiple bean instances of the same key
within a cluster.

Subject: can multiple instances of an entity bean with the same PK exist?
Hi everyone,
I was stumped by the following post on TheServerSide:
http://www.theserverside.com:8080/patterns/thread.jsp?thread_id=220#2665
Gal suggests that most ejbServers will load multiple instances of
an
entity bean with the same primary key inorder to service multiple
clients.
Is this true? Which app. servers do this?
He also suggests that serializeable transactions on these beans
won't
really be serializeable, how is that possible? What does it matter what
concurrency algorith is used, the spec says serializeable transactions
must
occur in a serial fashion, so thats all a developer should be concerned
with
right?
dazed and confused,
Floyd Marinescu
