BusinessObjects Enterprise Administrator's Guide

Increasing overall system capacity

As the number of report objects and users on your system increases, you can increase the overall system capacity by clustering two (or more) Central Management Servers (CMS). You can install multiple CMS services/daemons on the same machine. However, to provide server redundancy and fault-tolerance, you should ideally install each cluster member on its own machine.

CMS clusters can improve overall system performance because every BusinessObjects Enterprise request results, at some point, in a server component querying the CMS for information that is stored in the CMS database. When you cluster two CMS machines, you instruct the new CMS to share in the task of maintaining and querying the CMS database.

For more information, see "Clustering Central Management Servers" on page 94.
