如何连接到 IBM MQ 统一集群

Question

我最近发布了这个 如何重新连接到集群中的所有 IBM MQ 队列管理器 问题，有人建议我使用统一的集群作为解决方案。通读文档似乎正是我们所需要的。

我们的基础架构人员配置了统一集群，我正在尝试连接到它并测试功能。

为了连接到它，我创建了一个类似于以下内容的 json CCDT 文件：

{
  "channel":
  [
    {
      "general":
      {
        "description": "My channel",
        "maximumMessageLength": 4194304
      },
      "name": "CHANNEL.NAME",
      "clientConnection":
      {
        "connection":
        [
          {
            "host": "server1",
            "port": 1414
          }
        ],
        "queueManager": "QM1"
      },
      "transmissionSecurity":
      {
        "cipherSpecification": "TLS_AES_256_GCM_SHA384"
      },
      "type": "clientConnection"
    },
    {
      "general":
      {
        "description": "My channel",
        "maximumMessageLength": 4194304
      },
      "name": "CHANNEL.NAME",
      "clientConnection":
      {
        "connection":
        [
          {
            "host": "server2",
            "port": 1414
          }
        ],
        "queueManager": "QM2"
      },
      "transmissionSecurity":
      {
        "cipherSpecification": "TLS_AES_256_GCM_SHA384"
      },
      "type": "clientConnection"
    },
    {
      "general":
      {
        "description": "My channel",
        "maximumMessageLength": 4194304
      },
      "name": "CHANNEL.NAME",
      "clientConnection":
      {
        "connection":
        [
          {
            "host": "server3",
            "port": 1414
          }
        ],
        "queueManager": "QM3"
      },
      "transmissionSecurity":
      {
        "cipherSpecification": "TLS_AES_256_GCM_SHA384"
      },
      "type": "clientConnection"
    },
    {
      "general":
      {
        "description": "My channel",
        "maximumMessageLength": 4194304
      },
      "name": "CHANNEL.NAME",
      "clientConnection":
      {
        "connection":
        [
          {
            "host": "server1",
            "port": 1414
          },
          {
          "host": "server2",
          "port": 1414
          },
          {
          "host": "server3",
          "port": 1414
          }
        ],
        "queueManager": "*"
      },
      "transmissionSecurity":
      {
        "cipherSpecification": "TLS_AES_256_GCM_SHA384"
      },
      "type": "clientConnection"
    }
  ]
}

换句话说，我试图创建一个到每个队列管理器的客户端连接，以及一个到三个队列管理器组的第四个连接。最初此条目不在文件“queueManager”中：“*”但是在尝试运行时我得到missing required attribute。这让我把那个“*”。错误消失了，但我仍然无法连接，这让我认为我的 CCDT 配置有误。在客户端，我有这个

ConnectionFactory

创作：

        connectionFactory.setTransportType(WMQ_CM_CLIENT);
        if (Objects.isNull(ccdtUrl)) {
            connectionFactory.setConnectionNameList(connectionNameList);
            connectionFactory.setChannel(queueManagerChannel);
            connectionFactory.setPort(connectionPort);
        } else {
            connectionFactory.setCCDTURL(ccdtUrl);
        }
        connectionFactory.setCCSID(1208);
        connectionFactory.setClientReconnectOptions(WMQ_CLIENT_RECONNECT_Q_MGR);
        connectionFactory.setClientReconnectTimeout(reconnectTimeout);
        connectionFactory.setAppName(applicationName);

        if (sslEnabled) {
            connectionFactory.setSSLCipherSuite(sslCipherSuite);
            connectionFactory.setSSLFipsRequired(sslFipsRequired);
            System.setProperty("com.ibm.mq.cfg.useIBMCipherMappings", useIBMCipherMappings);
        }

你能告诉我我做错了什么吗？我该如何解决。我以前没用过CCDT。

提前谢谢你。
