DLQ

Check that the queue manager you will be using has enabled DLQ processing.

检查要使用的队列管理器是否启用了DLQ处理功能。

If the retry fails, then custom DLQ rules should be used to forward or remove the messages as needed.

如果重试失败，则应该使用自定义的DLQ规则，根据需要转发或删除消息。

The DLQ is a local queue that is also referred as the undelivered-message queue.

DLQ是一个本地队列，也称为未送达消息队列。

If you do not define a DLQ, errors in the application programs may cause channels to shut down.

如果不定义DLQ，应用程序中的错误可能导致通道关闭。

Under restrictive application environments where exact processing of messages in order needs to be assured, a DLQ can be omitted to force a shutdown of the processing.

在必须保证确切地按顺序处理消息的严格应用程序环境中，可以省略DLQ以强制关闭消息的处理。

In addition, the DLQ should be monitored as messages arriving in that queue are likely an error.

此外，应该对DLQ进行监视，因为到达该队列的消息可能是错误。

MQ provides a sample DLQ handler ( runmqdlq/ amqsdlq) for your learning and experimentation.
