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) Automated Process Schedulers (APS). You can install multiple APS 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.

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