Question

我无法获得可重播的数据源（代码附在下面）。

    PoolDataSource  pds = PoolDataSourceFactory.getPoolDataSource();
                                 pds.setConnectionFactoryClassName("oracle.jdbc.replay.OracleDataSourceImpl");

                                 System.out.println("connection factory set");

                                 String URL = "jdbc:oracle:thin:@(DESCRIPTION = (TRANSPORT_CONNECT_TIMEOUT=3) (RETRY_COUNT=20)(FAILOVER=ON) " +
                                  " (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521)) (CONNECT_DATA = " +
                                  " (SERVER = DEDICATED) (SERVICE_NAME=orcl)))";
                                 System.out.println("Using URL\n" + URL);
                                 pds.setURL(URL);
                                 pds.setUser("system");
                                 pds.setPassword("oracle");

                                 pds.setInitialPoolSize(10);
                                 pds.setMinPoolSize(10);
                                 pds.setMaxPoolSize(20);
                                 pds.setConnectionWaitTimeout(10);
                                 // RAC Features
                                 pds.setConnectionPoolName("Application Continuity Pool");
                                 pds.setFastConnectionFailoverEnabled(true);

                                 System.out.println("pool configured, trying to get a connection");

                                 Connection conn = null;

                                 try{
                                           conn = pds.getConnection();
                                 }catch(Exception e){
                                           e.printStackTrace();
                                 }

                                 if (conn == null || !((ValidConnection) conn).isValid())  {

                                   System.out.println("connection is not valid");
                                   throw new Exception ("invalid connection obtained from the pool");
                                 }

                                 if ( conn instanceof oracle.jdbc.replay.ReplayableConnection ) {
                                   System.out.println("got a replay data source");
                                 } else {
                                   System.out.println("this is not a replay data source. Why not?");
                                 }

以下是我从上面代码中获取的系统打印件，它显示连接实例不是可重放类型。

连接工厂集使用URL jdbc：oracle：thin：@（DESCRIPTION = （TRANSPORT_CONNECT_TIMEOUT = 3）（RETRY_COUNT = 20）（FAILOVER = ON）（地址） =（PROTOCOL = TCP）（HOST = localhost）（PORT = 1521））（CONNECT_DATA =（SERVER = DEDICATED）（SERVICE_NAME = orcl）））池配置，尝试 获取连接这不是重播数据源。为什么不呢？

我从下面的网站获得了代码并修改了一些内容以添加线程并模拟AC。但我无法获得可重播的数据源。

请确保您的类路径中有oracle.jdbc.replay.OracleDataSourceImpl，换句话说，请确保您的类路径中有12.1.0.2 JDBC驱动程序。
