What is Cluster? Ans: A cluster is a group of queue managers set up in such a way that the queue managers can communicate directly with one another over a single network, without the need for transmission queue, channel, and remote queue definitions.   Some important MQSC commands that work with cluster DISPLAY CLUSQMGR SUSPEND CLUSQMGR RESUME CLUSQMGR REFRESH CLUSTER RESET CLUSTER     What are the Advantages of clustering? Advantages: Reduced system administration Increased high availability Improved resource utilization Workload sharing What is the algorithm that is followed by MQ in clustering? Ans: WebSphere MQ uses a workload management algorithm that uses a round-robin routine to select an available queue manager to route a message to.   What is Cluster queue manager? A cluster Queue manager is a queue manager that is a member of a cluster. A queue manager can be a member of more than one cluster   What happens when we give a Refres

What is MQ and what does it do? Ans. MQ stands for MESSAGE QUEUEING. WebSphere MQ allows application programs to use message queuing to participate in message-driven processing. Application programs can communicate across different platforms by using the appropriate message queuing software products. What is Message driven process? Ans . When messages arrive on a queue, they can automatically start an application using triggering . If necessary, the applications can be stopped when the message (or messages) have been processed. What are advantages of the MQ? Ans. 1. Integration. 2. Asynchrony 3. Assured Delivery 4. Scalability. How does it support the Integration? Ans . Because the MQ is independent of the Operating System you use i.e. it may be Windows, Solaris,AIX.It is independent of the protocol (i.e. TCP/IP, LU6.2, SNA, NetBIOS, UDP).It is not required that both the sender and receiver should be running on the same platform
