[英]WMQ copy messages between queue managers
I have a queue Q1 on queue manager QMA and an app A reading the data from Q1. 我在队列管理器QMA上有一个队列Q1,并且有一个应用A从Q1读取数据。 The data from Q1 needs to be replicated to another queue Q2 on queue manager QMB with app A still reading from Q1 and Q2 also getting the message.
来自Q1的数据需要复制到队列管理器QMB上的另一个队列Q2,同时应用A仍从Q1和Q2读取消息。 I make Q1 an alias queue which posts its data on a topic (TopicA) to which Q2 has subscribed via a remote queue.
我将Q1设置为别名队列,该别名队列将其数据发布到Q2通过远程队列订阅的主题(TopicA)上。 Q2 is able to get the data.
Q2能够获取数据。 The problem is app A which was reading from Q1 is not able to get the data.
问题是正在从Q1读取的应用程序A无法获取数据。 Can this be re-modelled so that both app A and Q2 gets the data?
可以重新建模以便应用程序A和Q2都获取数据吗?
Create another durable subscription for TopicA
with destination as Q3
and change your application get messages from queue Q3
instead of Q1
. 为
TopicA
创建另一个持久订阅,目标为Q3
并更改应用程序从队列Q3
而不是Q1
获取消息。 When an application puts message to Q1
(basically to alias topic TopicA
) that message gets routed to both Q2
on QMB
and Q3
on QMA
. 当应用程序将消息放入
Q1
(基本上是别名TopicA
)时,该消息将同时路由到QMB
上的Q2
和QMA
上的Q3
。
If you are able to change the queue for your putting application, then follow below steps: 如果您能够更改您的放置应用程序的队列,请按照以下步骤操作:
- Make Q1 as local queue instead of alias queue.
使Q1作为本地队列而不是别名队列。
- Create another alias queue, say "Publisher", with Base object as topic and give your topic in destination as you did before.
创建一个别名队列,例如“ Publisher”,以基础对象作为主题,并像以前一样在目标中提供主题。
- Create Subscriptions for queue Q1, for your topic.
为您的主题为队列Q1创建订阅。
- Point your putting application to put messages in the "Publisher" queue instead of Q1.
将您的放置应用程序指向将消息放置在“发布者”队列中而不是Q1中。
