Ibm mq 如何在没有计时器的情况下重新连接到IBM MQ
我编写了一些代码来从远程mq获取消息,但在消息无法进入队列后,我断开了与mq的连接。然后我想重新连接到MQ。我为此添加了计时器。但它增加了开放输入计数。有没有办法在没有定时器的情况下重新连接?任何线索都可以 代码 C#代码 所以这里我用定时器重新连接,但它增加了打开的输入计数。请帮忙 所以这里我用定时器重新连接,但它增加了打开的输入计数 这是因为在再次打开队列之前,您没有关闭队列Ibm mq 如何在没有计时器的情况下重新连接到IBM MQ,ibm-mq,Ibm Mq,我编写了一些代码来从远程mq获取消息,但在消息无法进入队列后,我断开了与mq的连接。然后我想重新连接到MQ。我为此添加了计时器。但它增加了开放输入计数。有没有办法在没有定时器的情况下重新连接?任何线索都可以 代码 C#代码 所以这里我用定时器重新连接,但它增加了打开的输入计数。请帮忙 所以这里我用定时器重新连接,但它增加了打开的输入计数 这是因为在再次打开队列之前,您没有关闭队列 queueManager = new MQQueueManager(QueueManagerName, channe
queueManager = new MQQueueManager(QueueManagerName, channelName, connectionName);
以这种方式使用MQQueueManager类意味着不存在安全性,即SSL/TLS或安全出口。坏主意。您应该在哈希表中设置连接信息,并将哈希表传递给MQQueueManager类
此外,您应该使用“MQGet with wait”,而不是使用计时器进行轮询
下面是一个示例C#程序,它使用哈希表作为连接信息并执行“MQGet with wait”:
