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 happe...

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

MQ Series : - It is an IBM web sphere product which is evolved in 1990’s. MQ series does transportation from one point to other. It is an EAI tool (Middle ware) VERSIONS :-5.0, 5.1, 5.3, 6.0, 7.0(new version). The currently using version is 6.2 Note : - MQ series supports more than 35+ operating systems. It is platform Independent. For every OS we have different MQ series software’s. But the functionality of MQ series Default path for installing MQ series is:- C: programfiles\IBM\Eclipse\SDK30 C: programfiles\IBM\WebsphereMQ After installation it will create a group and user. Some middleware technologies are Tibco, SAP XI. MQ series deals with two things, they are OBJECTS, SERVICES. In OBJECTS we have QUEUES CHANNELS PROCESS AUTHENTICATION QUERY MANAGER. In SERVICES we have LISTENERS. Objects : - objects are used to handle the transactions with the help of services. QUEUE MANAGER maint...

What is Triggering? Ans: Web Sphere MQ enables you to start an application automatically when certain conditions on a queue are met. For example, you might want to start an application when the number of messages on a queue reaches a specified number. This facility is called triggering How many ways of Triggering? EVERY: A trigger event occurs every time that a message arrives on the application queue. Use this type of trigger if you want a serving program to process only one message, then end. FIRST: A trigger event occurs only when the number of messages on the application queue changes from zero to one. Use this type of trigger if you want a serving program to start when the first message arrives on a queue, continue until there are no more messages to process, then end. DEPTH: A trigger event occurs only when the number of messages on the application queue reaches the value of the TriggerDepth attribute. What are the Trigger types available Explain? a. Application tr...

Creating Cluster and WAS instance in WebSphere Application Server. One good article which I have read in WebSphereGuru. They have given given very useful information about how to create cluster and WAS instance in WebSphere Application Server. They have descripted with screen shots of each and every step in creating a cluster and WAS instance. Please click on below link to read / download pdf. Cluster creation & WAS instance creation

This video presentation shows a technical overview of the IBM Tivoli Composite Application Manager for WebSphere/J2EE solution.

This video highlights the features available in Health Center. Health Center is a low-processor and memory usage diagnostic tool for monitoring the status of a running IBM Java Virtual Machine (JVM). Health Center provides live information and recommendations in each of the following areas: - Classes: information about classes being loaded - Environment: details of the configuration and system of the monitored application - Garbage Collection: information about the Java heap and pause times - Locking: information about contention on inflated locks - Profiling: sampling profile of Java methods including call paths

This video guide takes you through the necessary steps to install and launch Health Center from the IBM Support Assistant. Health Center is a low-processor and memory usage diagnostic tool for monitoring the status of a running IBM Java Virtual Machine (JVM). Health Center provides live information and recommendations in each of the following areas: * Classes: information about classes being loaded * Environment: details of the configuration and system of the monitored application * Garbage Collection: information about the Java heap and pause times * Locking: information about contention on inflated locks * Profiling: sampling profile of Java methods including call paths.
