The BdbServerConnection class is not thread-safe. Furthermore, objects created from a BdbServerConnection instance use the connection object internally for remote invocations. Therefore, they are not thread-safe either. The connection object together with all objects created from it must be used in a single thread, because they all share the same connection object. For example, if we create a BdbServerAdmin object, a SEnvironment object from a BdbServerConnection object, a SDatabase object, and a STransaction object from the SEnvironment object, all five objects must be accessed in a single thread.

For a multi-threaded application, you can create multiple instances of BdbServerConnection each in a separate thread. Then, if necessary, you can open the same environment or database from multiple connections to access the same environment or database concurrently.
