对于特定主题，MessageProducer.send()太慢 [英] MessageProducer.send() is too slow for a particular topic

问题描述

我缩小了所要解决的问题的范围，结果发现为特定主题"replyfeserver"创建的MessageProducer.send()太慢了:

I've narrowed down the area of the problem I'm facing and it turned out that MessageProducer.send() is too slow when it is created for a particular topic "replyfeserver":

auto producer = context.CreateProducerFromTopic("replyfeserver");

producer->send(textMessage); //it is slow

在这里，对send()块的调用有时最多持续55-65秒—几乎每4-5次通话之后，一般就最多5-15秒.

Here the call to send() blocks for up to 55-65 seconds occasionally — almost every after 4-5 calls, and up to 5-15 seconds in general.

但是，如果我使用其他主题，请说"feserver.action.status".

However, if I use some other topic, say "feserver.action.status".

auto producer = context.CreateProducerFromTopic("feserver.action.status");

producer->send(textMessage); //it is fast!

现在，对send()的调用会立即在几分之一秒之内返回.我已经尝试了send()的其他几个主题，它们都足够快地工作.

Now the call to send() returns immediately, within a fraction of second. I've tried send() with several other topics and all of them work fast enough.

此特定主题"replyfeserver"可能有什么问题?为了诊断问题，我应该看什么?最近两个月我一直在使用此主题.

What could be the possible issues with this particular topic "replyfeserver"? What are the things I should look at in order to diagnose the issue with it? I was using this topic for last 2 months.

我正在使用XMS C ++ API，请假定context对象是创建会话，目的地，使用者，生产者等的抽象.

I'm using XMS C++ API and please assume that context object is an abstraction which creates session, destination, consumer, producer and so on.

我还想知道这两种方法之间是否有任何区别:

I'd also like to know if there is any difference between these two approaches:

xms::Destination dest("topic://replyfeserver");

vs

xms::Destination dest = session.createTopic("replyfeserver");

我尝试过两者，都没有任何区别—至少我没有注意到它.

I tried with both, it doesn't make any difference — at least I didn't notice it.

推荐答案

应该没有什么区别.就个人而言，我喜欢将我的主题放在一个层次结构中.即A.B.C

There shouldn't be any difference. Personally, I like to have my topics in a hierarchy. i.e. A.B.C

我将运行MQ跟踪，然后与IBM打开PMR，并给他们跟踪，并说请解释延迟.

I would run an MQ trace then open a PMR with IBM and give them the trace and say please explain the delay.
