为什么在尝试使用PCF获取信道信息时会出现MQRC_NOT_AUTHORIZED错误？

Question

我正在使用MQ Java PCF API从MQ安装中检索信息。类PCFMessageAgent有几个构造函数。有一个接受主机、端口和通道名称。我展示了文档的摘录。

    PCFMessageAgent agent = new PCFMessageAgent(host, port, "SYSTEM.DEF.SVRCONN");
    PCFMessage pcfCmd = new PCFMessage(MQConstants.MQCMD_INQUIRE_CHANNEL);
    pcfCmd.addParameter(MQConstants.MQCACH_CHANNEL_NAME, channelName);
    PCFMessage[] pcfResponse = agent.send(pcfCmd);

Exception in thread "main" com.ibm.mq.MQException: MQJE001: Completion Code '2', Reason '2035'.
    at com.ibm.mq.MQManagedConnectionJ11.<init>(MQManagedConnectionJ11.java:249)

    at com.ibm.mq.MQSimpleConnectionManager.allocateConnection(MQSimpleConnectionManager.java:194)
    at com.ibm.mq.MQQueueManagerFactory.obtainBaseMQQueueManager(MQQueueManagerFactory.java:868)

为什么我会得到这个错误？我怎么解决这个。

我在错误日志中找到了这个。任何帮助都将不胜感激。

AMQ9777: Channel was blocked

EXPLANATION:
The inbound channel 'SYSTEM.DEF.SVRCONN' was blocked from address
'192.168.56.101' because the active values of the channel matched a record
configured with USERSRC(NOACCESS). The active values of the channel were
'CLNTUSER(user1)'.
ACTION:
Contact the systems administrator, who should examine the channel
authentication records to ensure that the correct settings have been
configured. The ALTER QMGR CHLAUTH switch is used to control whether channel
authentication records are used. The command DISPLAY CHLAUTH can be used to
query the channel authentication records.

AMQ9999: Channel 'SYSTEM.DEF.SVRCONN' to host '192.168.56.101' ended
abnormally.

EXPLANATION:
The channel program running under process ID 3294 for channel
'SYSTEM.DEF.SVRCONN' ended abnormally. The host name is '192.168.56.101'; in
some cases the host name cannot be determined and so is shown as '????'.
ACTION:
Look at previous error messages for the channel program in the error logs to
determine the cause of the failure. Note that this message can be excluded
completely or suppressed by tuning the "ExcludeMessage" or "SuppressMessage"
attributes under the "QMErrorLog" stanza in qm.ini. Further information can be
found in the System Administration Guide.

Answer 1

问题是您试图连接到通道system.dev.svrconn。默认情况下，有一个Chlauth规则阻止对名为System.*的通道的访问。

您可以创建一个新的SVRCONN通道，该通道的名称不以system开头，并且它将通过此检查。
