Question

我正在使用Oracle UCP（通用连接池）。处理大约100K记录后，我收到以下错误。

    oracle.ucp.UniversalConnectionPoolException: Invalid life cycle state. Check the status of the Universal Connection Pool

以下是创建DataSource

的代码段

PoolDataSource dataSource = PoolDataSourceFactory.getPoolDataSource();


    dataSource.setURL("jdbc.url"));
    dataSource.setUser("jdbc.user"));
    dataSource.setPassword("jdbc.password"));
    dataSource.setMaxConnectionReuseCount(100);

    dataSource.setInitialPoolSize(50);
    dataSource.setMinPoolSize(50);

    dataSource.setMaxPoolSize(100);

    dataSource.setValidateConnectionOnBorrow(true);

    dataSource.setConnectionFactoryClassName("oracle.jdbc.pool.OracleDataSource");

然后我从数据源获得连接

datasource.getConnection();
