Six-machine setup

This third configuration mirrors the three-machine setup. You maintain the logical breakdown of processing based on the types of work performed by each server, but you increase the number of available machines and servers for redundancy and fault-tolerance. For instance, if a server stops responding, or if you need to take one or two machines offline completely, you need not interrupt Crystal Enterprise requests in order to service the system.

This tested configuration is designed to meet the reporting requirements of 85% of all deployment scenarios. If you have further requirements or more advanced configuration needs, contact your Crystal Decisions sales representative for additional assistance.

Note:    It is recommended that you use six multi-processor machines (dual-CPU or better), with at least 2 GB RAM installed on each machine.

• Install the three-machine setup first. Verify that Crystal Enterprise is functioning correctly. For details, see Three-machine setup.
• Install a second APS/Event Server pair on the fourth machine. This machine must be on the same subnet as the APS that you have already installed.

  Cluster the two APS services, so they share the task of maintaining the APS database. Ensure that each APS accesses the APS database in exactly the same manner (the same database client software, the same database user name and password, and so on).

  Tip:    Here, the Event Server is installed on the same machine as the APS. In general, however, the Event Server should be installed on the machine where your monitored, file-based events occur.

• Install a second WCS/Cache Server pair on the fifth machine.

  Modify your Web Connector configuration to ensure that the Web Connector communicates with the two distinct WCS hosts.

• Install a second Page Server/Job Server on the remaining machine.

  Ensure that all Page Servers and Job Servers can access your reporting database in exactly the same manner. Install and configure any required database client software similarly on each machine, along with any ODBC DSNs that are required for your reports.
