在单个连接和单个会话中可以打开多少个队列是否有限制?我目前可以打开 128 个队列并向它们发送消息。如果我尝试打开 129,我会收到以下错误...

谢谢

错误:

Use the linked exception to determine the cause of this error. Check that the specified queue and queue manager are defined correctly.

这由队列管理器的MAXHANDS属性控制。

默认值为 256。根据您访问队列的方式,每个类可能会打开两次,从而最多打开 128 个队列。

DIS QSTATUS您可以使用命令在 runmqsc 中显示队列句柄。
