Cognos ReportNetTM Installation and Configuration Guide

Chapter 1: ReportNet
Installing ReportNet Gateways On A Separate Computer
The ReportNet gateway manages all ReportNet communications. It can reside on one or more
Web servers.
You can install the ReportNet gateway and a Web server on one computer, and install the
remaining ReportNet components on other computers. If you have a Web farm, you may want to
install a ReportNet gateway on each Web server. Using multiple Web servers to manage
incoming requests provides a better level of service.
If you install only the ReportNet gateway component on the same computer as the Web server,
your Web server manages the core Web services and does not process user requests. This
separation of processing may be required if you have a firewall between the Web server and
your ReportNet server.
In the following diagram, two Web servers each have a gateway installed. Incoming requests are
passed to either gateway and forwarded to the report server computer. If request information is
not saved, the result is returned from the report server. If request information is saved, it is
saved in Content Manager.

Configuration Requirements
If you install one or more ReportNet gateways on a separate computer, you must ensure that
you can view ReportNet content and that the gateways can communicate with other ReportNet
components. On each computer where the ReportNet gateway is installed you must
• configure cryptographic properties
• configure your Web server to view ReportNet content
• configure the Dispatcher URI
Installing Report Servers and Content Manager on Separate Computers
One or more report servers use the Cognos Connection interface to balance loads, access data,
perform queries, schedule jobs, and render reports. Content Manager stores all report
specifications, results, packages, folders, and jobs in the content store.
You can install the report servers and Content Manager on the same computer, or on different
computers. Installing on different computers can improve performance, availability, and capacity.
To improve scalability in an environment in which there is typically a large volume of report
requests to process, you can install the report server on multiple computers dedicated to
processing incoming requests. By installing the report server on multiple computers, you
distribute and balance loads among the computers. You also have better accessibility and
throughput than on a single computer, as well as failover support.
