推荐答案
This is controlled by the queue manager's MAXHANDS attribute.
默认值为256.根据访问队列的方式，每个类可能会打开两次，从而导致128个最大打开队列.
The default is 256. Depending on how you access the queues, the classes may be opening each one twice, resulting in 128 max open queues.
You can display the queue handles in runmqsc with the DIS QSTATUS command.
