问题描述
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个队列并将消息发送给它们.如果我尝试打开129，则会出现以下错误...
is there a limit on how many queues I can have open within a single connection and single session? I can currently open up 128 queues and send messages to them. If I try to open up 129 I get the following error...
谢谢
错误:
com.ibm.msg.client.jms.DetailedResourceAllocationException: JMSWMQ2008: Failed to open MQ queue 'TestQueue_129'. JMS attempted to perform an MQOPEN, but WebSphere MQ reported an error. Use the linked exception to determine the cause of this error. Check that the specified queue and queue manager are defined correctly.

推荐答案
这由队列管理器的 MAXHANDS 属性.
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.
您可以使用 DIS QSTATUS 命令.
You can display the queue handles in runmqsc with the DIS QSTATUS command.
