用大日志启动HornetQ OutOfMemory [英] HornetQ OutOfMemory on startup with big journal

问题描述

使用:HornetQ 2.0.0.CR2 独立/非群集服务器的默认配置.

Using: HornetQ 2.0.0.CR2 Default configurations for the stand-alone/non-clustered server.

当我尝试使用大日志(> 1Gb)启动服务器时，出现了OutOfMemory异常:

When I try to startup the server with a big journal (> 1Gb), I got a OutOfMemory exception:

在现实生活中，当使用者停止处理消息而我需要重新启动服务器时，可能会发生这种情况.

This could happen in real life when a consumer stops processing the messages and I need to restart the server.

有什么解决方法吗?还是我应该尝试修改哪些配置?

There is any workaround for this? Or which configurations should I try to modify?

推荐答案

事实证明，完全避免此问题很简单.

It turns out it was simple to completely avoid this problem.

分页 在默认配置中未启用！

The Paging it's not enabled in the default configuration!

在hornetq-configuration.xml上添加以下两行即可达到目的:

Adding these 2 lines on the hornetq-configuration.xml should do the trick:

   <address-settings>
      <!--default for catch all-->
      <address-setting match="#">
         <dead-letter-address>jms.queue.DLQ</dead-letter-address>
         <expiry-address>jms.queue.ExpiryQueue</expiry-address>
         <redelivery-delay>0</redelivery-delay>
         <page-size-bytes>10485760</page-size-bytes>
         <message-counter-history-day-limit>10</message-counter-history-day-limit>

         <!-- Add these 2 lines -->
         <max-size-bytes>104857600</max-size-bytes>
         <address-full-policy>PAGE</address-full-policy>

      </address-setting>
   </address-settings>

现在可能有巨大的队列等待处理.

Now it's possible to have huge queues waiting to be processed.
