骡子VM队列线程配置 [英] Mule VM Queue thread configuration

问题描述

我正在尝试了解如何使用3.5 CE微调Mule中的线程配置文件

flow 1

从FTP终结点提取文件并将其池化为VM队列。

流程2

在启用事务的情况下读取上述VM队列，并执行一些业务逻辑处理。

---

我假设流2将基于VM连接器线程配置在多个线程中执行。但是我注意到第二个流总是使用4个线程来并行执行它。我已经尝试配置默认线程配置文件，但也没有任何不同。请告诉我我错过了什么。感谢任何帮助

虚拟机连接器配置示例

  <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>

推荐答案

调试Mule Jars的源代码后，我想我还需要设置轮询VM队列的使用者数量。

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

它现在工作得很好。希望这对某些人有帮助

<vm:connector name="ITS_VM" validateConnections="true" createMultipleTransactedReceivers="true" numberOfConcurrentTransactedReceivers="30">
