The only way to get this information is through API calls. If you have a Server (oracle.toplink.threetier) you can ask the read and default (write) connection pools.
        // Display Read Connection pool info       
        System.out.println("READ Available: " +
                           server.getReadConnectionPool().getConnectionsAvailable().size());
        System.out.println("READ Minimum: " +
                           server.getReadConnectionPool().getMinNumberOfConnections());
        System.out.println("READ Maximum: " +
                           server.getReadConnectionPool().getMaxNumberOfConnections());
        // Display Write Connection pool info       
        System.out.println("WRITE Available: " +
                           server.getDefaultConnectionPool().getConnectionsAvailable().size());
        System.out.println("WRITE Minimum: " +
                           server.getDefaultConnectionPool().getMinNumberOfConnections());
        System.out.println("WRITE Maximum: " +
                           server.getDefaultConnectionPool().getMaxNumberOfConnections());Doug
