As a CA Service Catalog administrator, you can optionally use clustering for CA Workflow and Service View to improve performance and provide "failover" protection. Here, the term clustering means multiple computers grouped together performing the same or similar function, thereby acting as one virtual computer. Specifically, clustering here refers to CA Workflow and Service View running on two or more computers. Failover" protection means that if one computer malfunctions, becomes heavily loaded, or loses power, its workload is transferred to the other computers in the cluster, retaining users' sessions.
Another advantage of clustering is load-balancing: if one of the cluster components is busy processing a request, the load is redirected to another component in the cluster. Users of the system see no interruption of access. Thus, CA Workflow and Service View processing for CA Service Catalog continues and the loss of performance on users and business functions is minimized, even when computer availability is "lost" or "reduced."
For details and instructions to implement clustering for Service View, CA Workflow, or both, see the chapter "Clustering."
