Mule VM Queue线程配置

Question

我试图了解如何使用3.5 CE

微调Mule中的线程配置文件

初级流瑜伽

从FTP端点获取文件并将其汇集到VM队列中。

流程2

在启用事务的情况下从上述VM队列中读取并执行一些业务逻辑处理。

---

我假设Flow 2将基于VM连接器线程配置在多个线程中执行。但我注意到第二个流程总是使用4个线程来并行执行它。尝试配置默认线程配置文件，它也没有任何区别。请让我知道我错过了什么。任何帮助表示赞赏

示例VM连接器配置

  <vm:connector name="ITS_VM" validateConnections="true"   >
    <receiver-threading-profile  maxThreadsIdle="30" maxBufferSize="5000" maxThreadsActive="40"/>
    <dispatcher-threading-profile maxThreadsIdle="30" maxBufferSize="5000" maxThreadsActive="40"/>
     <vm:queue-profile  maxOutstandingMessages="500">
         </vm:queue-profile>
    </vm:connector>

示例默认配置

<configuration >
    <default-threading-profile  maxThreadsIdle="30" maxBufferSize="5000" maxThreadsActive="40" />
    <default-dispatcher-threading-profile maxThreadsIdle="30" maxBufferSize="5000" maxThreadsActive="40"/>
    <default-receiver-threading-profile maxThreadsIdle="30" maxBufferSize="5000" maxThreadsActive="40" />
        </configuration>

Answer 1

从Mule jar调试源代码后，我发现我还需要设置轮询VM队列的消费者数量。

我通过将vm：connector上的numberOfConcurrentTransactedReceivers设置为更高的数字来实现此功能。默认值为4，这就是我只看到4个并行线程的原因。

现在工作正常。希望这对某人有用

<vm:connector name="ITS_VM" validateConnections="true" createMultipleTransactedReceivers="true" numberOfConcurrentTransactedReceivers="30"＆gt;

查看文档中的this页面，您会发现：

  

Mule ESB应用程序是一组流程的协作。   从概念上讲，消息由流程分三个阶段处理：

     

  
1. 入站连接器收到的邮件
  
2. 正在处理的邮件
  
3. 通过出站连接器发送的邮件
  

然后：

  

调整Mule的性能涉及分析和改进这些   每个流程分三个阶段。您可以从应用相同的调整开始   接近所有流程，然后进一步定制每个流程的调整   根据需要流动。

您可以阅读计算主题部分，了解如何理解您的需求。
