                transactions and units of work. The database session is
                intended for usage in two-tier client-server
                applications. Although it could be used in a server
                situation, it is limitted to only having a single
                database connection and only allows a single open
                database transaction.

                The read connection pool is used for read access through
                the server session. Any of the connection pools can be
                used for the read pool however this is the default. This
                pool allows for concurrent reads against the same JDBC
                connection and requires that the JDBC connection support
                concurrent read access.
