Tibjms javax.jms.JMSException：服务器未知的连接

标签： java jms tibco tibco-ems

我正在使用 Tibjms jar进行JMS连接，并且在正常情况下工作正常，但是如果与jms提供程序的连接丢失然后又返回，我会遇到问题。为了重现这个问题，我执行了以下步骤 -

  1. 连接到Intranet并启动服务器。工作正常。

  2. 断开内联网连接。它开始尝试重新连接服务器。细

  3. 再次连接到Intranet。它抛出未知的异常，再也不会连接。问题

    4. 所以，我的问题是“javax.jms.JMSException：连接未知的服务器”，它没有告诉我太多，你可以在日志结束时看到它。

    您可以从以下日志中看到它 -

    我的代码 - 

        @PostConstruct
    public void configurePaxJmsClient() {

        try {
            // create Topic Connection Factory
            TibjmsTopicConnectionFactory cf = new TibjmsTopicConnectionFactory(serverUrl);
            cf.setSSLTrustedCertificate(sslCertificatePath);
            cf.setSSLEnableVerifyHostName(false);
            cf.setUserName(username);
            cf.setUserPassword(password);

            cf.setReconnAttemptCount(100);
            cf.setReconnAttemptDelay(60000);
            cf.setReconnAttemptTimeout(10000);

            cf.setConnAttemptCount(100);
            cf.setConnAttemptDelay(60000);
            cf.setConnAttemptTimeout(10000);

            Tibjms.setExceptionOnFTEvents(true);
            Tibjms.setExceptionOnFTSwitch(true);

            // creation the connection and install an exception handler
            connection = cf.createTopicConnection(username, password);
            connection.setExceptionListener(this);

            // You might also use CLIENT_ACKNOWLEDGE here
            session = connection.createTopicSession(false, javax.jms.Session.AUTO_ACKNOWLEDGE);
            Topic topic = session.createTopic(topicName);

            // Create the subscriber and install the listener
            TopicSubscriber ts;
            /*if (dsName == null || dsName.length() == 0) {
                ts = session.createSubscriber(topic);
            } else {
                ts = session.createDurableSubscriber(topic, dsName);
            }*/

            if (dsName == null || dsName.length() == 0) {
                ts = session.createSubscriber(topic, messageSelector, false);
            } else {
                ts = session.createDurableSubscriber(topic, dsName, messageSelector, false);
            }

            //
            ts.setMessageListener(this);
            connection.start();

        } catch (JMSException e) {
            LOGGER.error("Failed to connect with message:" + e.getMessage(), e);
            releaseResources();
        }
    }

    @Override
    public void onException(JMSException e) {
        LOGGER.error("Exception received from jms", e);
    }

    你们能告诉我这里有什么问题或者指出我正确的方向吗？

    另外，在spring bean的@PostConstruct中进行jms连接初始化是否可以？

1 个答案:

答案 0 :(得分：4)

为什么EMS报告“重新连接失败：id = xxxxx的连接未知”？ 此消息表明当客户端尝试重新连接时，EMS服务器没有或不再具有客户端连接信息。

有两个可能的原因：

  1. 参数“ft_reconnect_timeout”不够高。在客户端重新连接服务器之前，服务器已清除连接。 这可以通过为tibemsd.conf中的“ft_reconnect_timeout”参数设置更高的值来解决。默认值为60秒。

  2. 参数“ft_reconnect_timeout”是备份服务器等待客户端重新连接的时间（以秒为单位） （在故障转移情况下它承担主服务器的角色之后），此参数以秒为单位指定服务器将保留挂起连接的时间。 如果客户端在此时间段内未重新连接，则服务器会从共享状态文件中删除其状态。 如果客户端在“ft_reconnect_timeout”中设置的时间后尝试重新连接，则服务器没有客户端连接信息并打印“reconnect failed：connection unknown”消息。

    3. 因此建议您根据您的环境设置值并测试相同的值。也是 如果Ft_reconnect_timeout值很高，很多连接和连接相关的对象长时间保留在内存中，则可能存在内存问题。如果连接使用clientID，则可能会遇到“clientID已存在”问题。
