Create cluster with Websphere MQ

创建一个名为CLUSTER1的群集，其中包含QMGR1,QMGR2和QMGRI三个队列管理器，其中在QMGR1和QMGR2上创建INPUTQ的接收队列，并使得它们在群集中共享。

配置步骤如下(以下各步中给出相应的MQSC命令)：

1） 分别创建三个队列管理器。

2） 设置QMGR1和QMGR2为群集的两个完全仓储库，在两个队列管理上执行MQSC命令：ALTER QMGR REPOS(CLUSTER1) MQSC命令

·在QMGR1上执行MQSC命令：

DEFINE CHANNEL(TO.QMGR1) CHLTYPE(CLUSRCVR) TRPTYPE(TCP) CONNAME('9.68.58.228(1414)') CLUSTER(CLUSTER1) DEFINE CHANNEL(TO.QMGR2) CHLTYPE(CLUSSDR)  TRPTYPE(TCP) CONNAME('9.68.58.228(1415)') CLUSTER(CLUSTER1)

· 在QMGR2上执行MQSC命令：

DEFINE CHANNEL(TO.QMGR2) CHLTYPE(CLUSRCVR) TRPTYPE(TCP) CONNAME('9.68.58.228(1415)') CLUSTER(CLUSTER1) DEFINE CHANNEL(TO.QMGR1) CHLTYPE(CLUSSDR)  TRPTYPE(TCP) CONNAME('9.68.58.228(1414)') CLUSTER(CLUSTER1)

·在QMGRI上执行MQSC命令：

DEFINE CHANNEL(TO.QMGRI) CHLTYPE(CLUSRCVR) TRPTYPE(TCP) CONNAME('9.68.58.228(1416)') CLUSTER(CLUSTER1) DEFINE CHANNEL(TO.QMGR1) CHLTYPE(CLUSSDR)  TRPTYPE(TCP) CONNAME('9.68.58.228(1414)') CLUSTER(CLUSTER1)

3） 定义三个队列管理器的群集发送和群集接收通道。

4） 在QMGR1和QMGR2上定义群集共享队列INPUTQ，在QMGR1和QMGR2上，分别执行MQSC命令：DEFINE QLOCAL(INPUTQ) CLUSTER(CLUSTER1)这时，在QMGRI上可以看到这两个被共享出来的队列。

5） 验证配置成功在QMGRI上，利用MQ第一步中提供的例子程序API Exerciser，向INPUTQ发送消息，注意，在打开该队列的时候，一定要选择MQOO_BIND_NOT_FIXED选项。

            mq.put(putmessage, pmo);
            
            // disconnect mq manager
            mqmanager.disconnect();
            
            System.out.println("put message ok");
