java – Oracle驱动程序内存泄漏 – Tomcat

当我们尝试取消部署应用程序时,一些Oracle类似乎正在泄漏.我在使用旧的ojdbc14.jar驱动程序时没有看到这一点,但我们无法使用这些驱动程序,因为我们正在迁移到需要更新驱动程序的Oracle 11g.我猜这是Oracle驱动程序中的一个错误？有什么办法可以清理这些资源吗？我试过关闭数据库连接池和其他东西无济于事……

不使用Tomcat的连接池会更好吗？我们宁愿让服务器连接到数据库,但如果有必要,我们可以自己做…

我已经尝试添加ContextListener手动关闭我们的DBCP连接,但这没有帮助.

InitialContext initial = new InitialContext();

DataSource ds = (DataSource) initial.lookup("java:/comp/env/jdbc/myDS");

if (ds.getConnection() == null) {
    throw new RuntimeException("I failed to find the datasource");
}

LOG.debug("Found datasource.  Closing...");
BasicDataSource bds = (BasicDataSource) ds;

bds.close();
