This information applies to WebSphere MQ for Windows only.
The Microsoft Cluster Server (MSCS) enables you to connect servers into a cluster, giving higher availability of data and applications, and making it easier to manage the system. MSCS can automatically detect and recover from server or application failures.
MSCS supports failover of virtual servers, which correspond to applications, Web sites, print queues, or file shares (including their disk spindles, files, IP addresses, and so on).
Failover is the process by which MSCS detects a failure in an application on one computer in the cluster, and shuts down the disrupted application in an orderly manner, transfers its state data to the other computer, and re-initiates the application there.
This chapter introduces MSCS clusters (in Introducing MSCS clusters, describes setting up MSCS support (in Setting up WebSphere MQ for MSCS clustering) then tells you how to configure WebSphere MQ for MSCS clustering, in the following sections:
Finally, in Hints and tips on using MSCS, we give some useful hints on using MSCS with WebSphere MQ.
