【问题描述】：
我有一个独立的 java 客户端程序，可以将消息发送到 websphere mq 系统上的队列。我想避免为每条消息创建新的连接、会话和生产者，所以我使用 activemq-jms-pool 包（v5.11.1）提供的连接池设施。
这个连接池的设置如下：
this.fConnectionFactory = new PooledConnectionFactory();
((PooledConnectionFactory)this.fConnectionFactory).setConnectionFactory(mqConnectionFactory);
((PooledConnectionFactory)this.fConnectionFactory).setMaxConnections(1);
((PooledConnectionFactory)this.fConnectionFactory).setMaximumActiveSessionPerConnection(1);
((PooledConnectionFactory)this.fConnectionFactory).setExpiryTimeout(10 * 60 * 1000);
((PooledConnectionFactory)this.fConnectionFactory).setIdleTimeout(10 * 60 * 1000);
((PooledConnectionFactory)this.fConnectionFactory).setReconnectOnException(true);
((PooledConnectionFactory)this.fConnectionFactory).setCreateConnectionOnStartup(true);
我的 MQ 客户端本身是版本“7.5.0.5 - p750-005-150424”。 Websphere MQ 本身是版本 8。
但是，我有时会在日志中看到以下异常：
com.ibm.msg.client.wmq.v6.jms.internal.ConfigEnvironment$1: MQJMS2007: failed to send message to MQ queue.

是什么导致了这个错误（以及如何避免它）？ 没有网络问题，中间也没有防火墙。当发送不同消息之间有一段时间（如 5 分钟左右）时，似乎会出现此问题。
感谢您的帮助。

【问题讨论】：

SVRCONN 频道上的 SHARECNV 设置为什么？我觉得奇怪的是 7505 jar 文件会产生状态为 wmq.v6.jms 的错误，除非 SHARECNV 为 0。当 java 客户端获取 2009 时，MQ 队列管理器日志中有什么错误？
-
SHARECNV(0)关闭 v7 中引入的新频道功能，并使频道在 v6 和更早的模式下工作。正如@newbie 提到的，它还导致每个 JMS 连接和会话都在专用的 TCP/IP 连接上。您可以将其设置为SHARECNV(1)并在 v7 中引入通道功能，同时仍然让每个 JMS 连接和会话位于专用的 TCP/IP 连接上。添加的一项功能是心跳消息是双向的，在此之前，它们仅在客户端发出带有等待的 MQGET 调用时才从服务器流出。 -
出于性能原因，我会推荐
SHARECNV(1)。使用 HBINT(30) 将 ReceiveTimeout 设置为 60 秒。如果您在 60 秒内不发送消息，您会看到 2009 年吗？无论如何，我认为您会发现将SHARECNV设置为 1 或更大将解决您 2009 年的问题。一旦你确认它修复了它，我会写一个答案并将所有评论信息放入其中，格式更好，并提供文档链接。 -
该错误表明您在接收超时期间没有收到来自服务器的响应或连接中断，
HBINT(30)的接收超时将是60秒。此通道是否使用 TLS 或者是否存在会导致 java 进程阻塞而不将 HB 发送到队列管理器的东西（例如：垃圾收集、调试断点）？ z/OS 团队应该有权访问等效的 z/OS MQ 日志（例如控制台日志），该日志可以显示队列管理器对连接发生的事情。 -
仔细检查 MQ jar 文件的版本是否来自一致的 MQ 版本。请注意，在您的堆栈跟踪中，我看到两个版本：
[com.ibm.mq.jmqi.jar:7.5.0.8 - p750-008-170628]和[com.ibm.mqjms-7.5.0.5.jar:7.5.0.5 - p750-005-150424]，所有com.ibm.mq*.jar文件都应该来自同一版本的 MQ 客户端。另请注意，MQ v7.5 已于 2018 年 4 月 30 日停止支持，您最好使用更高版本的 8.0、9.0 或 9.1，这些都可以使用单个 jar 文件com.ibm.mq.allclient.jar以及 JMS 2.0 进行部署jms.jar.
