[Objectbridge-developers] Thread-Safety of OJB Classes

[Sasha H. <sha...@br...>]

Hi Thomas and friends,

I have some questions regarding the thread-safety of some of the OJB classes
as I will be using them in a multi-threaded application.

Here is the thread-safety of the key objects, as I understand them.  Please
correct me if I'm wrong.

ojb.server.OJB: Thread-safe - a single instance can be used by multiple
threads to instantiate databases.

org.odmg.Database (ojb.server.DatabaseImpl): Not thread-safe? - one instance
per thread.  Are there any issues/limitations with creating a pool of open
databases?

Also, from what I can determine from the source code, OJB maintains one
connection per JdbcConnectionDescriptor in the repository XML file.  Is that
correct?

Thanks,
