【问题描述】：

我正在正确关闭休眠连接，但在单击或刷新某些页面后出现此错误。我无法理解的问题是什么。我还检查了会话数，它也通过以下命令增加，并且还给出了程序代码：

托管bean代码：

public List<TrxFile> getFileDetails() 
        //SessionFactory sf = HibernateUtill.HibernateUtil.getSessionFactory();
        Session sess = HibernateUtill.HibernateUtil.getSessionFactory().openSession();
        java.util.List l = null;
        try 
            Query q = sess.createQuery("from Files");
            l = q.list();
            Iterator itr = l.iterator();

            return l;
         catch (HibernateException hbx) 
            hbx.printStackTrace();
         finally 
            sess.flush();
            sess.clear();
            sess.close();
            //sf.close();
            HibernateUtill.HibernateUtil.getSessionFactory().close();
        
        return l;

查找当前会话的命令：

SELECT COUNT(*)
  FROM v$session;

尽管适当地关闭了会话，但它的增加任何人都可以帮助 plzz

【参考方案1】：

确保您的 oracle 侦听器提供服务“XE”

  [bbrandt@limbo] ~/ $ lsnrctl status | grep XE
    Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC_FOR_XE)))
    Default Service           XE
      (DESCRIPTION=(ADDRESS=(PROTOCOL=ipc)(KEY=EXTPROC_FOR_XE)))
    Service "XE" has 1 instance(s).
      Instance "XE", status READY, has 1 handler(s) for this service...
    Service "XEXDB" has 1 instance(s).
      Instance "XE", status READY, has 1 handler(s) for this service...
    [bbrandt@limbo] ~/ $

在尝试任何其他客户端应用程序之前，请确保您能够像这样通过 sqlplus 连接到 服务：

sqlplus username/password@localhost:1521/XE

注意！始终使用 SERVICE_NAME (hostname:1521/SERVICE_NAME) 连接到 oracle 数据库。使用 SID (hostname:1521:SID) .... 连接到 oracle 数据库是 oracle 仅在 15 年前不鼓励的事情！

【讨论】：

是的，我已经检查了 sqlplus 用户名/密码@localhost:1521/XE 作为 sysdba，并且我成功连接到了 mydba。

看起来您遇到了资源限制。尝试增加进程参数。更改系统设置进程 = 150 范围 = spfile；反弹数据库。看看这里：dadbm.com/…

【参考方案2】：

最后试试这个解决方案。它对我有用。 在 try/catch 块中关闭连接，关闭连接后，写Thread.sleep(1000);

你可以这样写：

finally 
    try 
        if (conn != null && !conn.isClosed())
            
            conn.close();
            Thread.sleep(1000);
             
        
    catch (SQLException e) 
        e.printStackTrace();
    

【参考方案3】：

我也遇到了同样的问题。这个错误的原因是：

连接未关闭或长时间空闲。因此，oracle 中的进程将超出限制。 context.xml (apache tomcat) 中的非乐观池配置。

我为解决此问题而采取的步骤是：

使用 select * from v$resource_limit where resource_name = 'processes'; 检查当前进程数； 点击 jdk 安装文件夹的 bin 文件夹中的 jconsole.exe 中的 PerformGC 按钮。这样做，未关闭的空闲连接将被垃圾收集。

如果上述步骤没有解决您的问题，您可以尝试通过减少 context.xml(apache tomcat )

注意：如果堆大小更大，则可能会从巨大的终身对象中消耗更多的数据库进程。
