使用库pymqi连接到IBM MQ时出现以下错误。

它是一个集群的MQ通道

pymqi.MQMIError: MQI Error. Comp: 2, Reason 2539: FAILED: MQRC_CHANNEL_CONFIG_ERROR

请在下面查看我的代码。

queue_manager = "QMNAME"
channel = bytes(str("CHANNEL_NAME"))
host = "xx.xx.xx.xx"
port = "1800"
queue_name = "QN"
conn_info1 = bytes("%s(%s)" % (host, port))
message = b'{"alert":[{"timestamp":"Wed Jun 27 11:07:37 CDT 2018","shortDescription":"Last 24 hrs Sev 4 Volume Deviation is 84% lower than baseline","alertColor":"red","title":"Sev 4 Volume Deviation"}]}'

# Message Descriptor
put_mqmd = pymqi.MD()
qmgr = pymqi.connect(queue_manager, channel, conn_info1)
queue = pymqi.Queue(qmgr, queue_name)

在下面的行出现错误

qmgr = pymqi.connect(queue_manager, channel, conn_info1)

1 个答案:

答案 0 :(得分:2)

原因:

2539 (MQRC_CHANNEL_CONFIG_ERROR)错误是由于您尝试连接到队列管理器上非SVRCONN类型的通道而导致的。 MQ客户端必须连接到SVRCONN通道。

其他信息:

如果查看队列管理器错误日志,则会看到相应的AMQ9502错误,例如:

AMQ9502: Type of channel not suitable for action requested.

EXPLANATION:
The operation requested cannot be performed on channel 'CHANNEL_NAME'. Some
operations are only valid for certain channel types. This channel is a
'CLUSRCVR' channel type. For example, you can only ping or trigger a channel
from the initiating end.
ACTION:
Check whether the channel name is specified correctly.  If it is check that the
channel has been defined correctly.

分辨率:

确保在要连接的队列管理器上定义了一个SVRCONN通道。

故障排除:

MQ客户端附带一个示例程序amqscnxc,您可以使用它来测试在示例中指定的参数。例如,在Linux / Unix上(在Windows上,别名的引用可能有所不同),请执行以下操作:

amqscnxc -x 'xx.xx.xx.xx(1800)' -c CHANNEL_NAME QMNAME

结果将是相同的2539错误,但这确实表明它不是特定于pymqi的问题。
