The IBM Cognos TM1 Web multi-tiered architecture includes web client, web application server and data component tiers.
Tier 1: Web clients
The web clients tier allows users to access and interact with Cognos TM1 data using any of the supported web browsers. Users can work with Cognos TM1 cubes and Cognos TM1 Websheets.
Visit Cognos TM1 Software Environments (http://www.ibm.com/support/docview.wss?uid=swg27040698) for currently supported web browsers.
Tier 2: Web application server
Cognos TM1 Web runs on a Java-based web application server.
This tier provides support for converting and displaying Microsoft Excel worksheets as Cognos TM1 Websheets. This service also exports Websheets back to Microsoft Excel and PDF formats.
Tier 3: Data
This tier includes the Cognos TM1 Admin Server and at least one Cognos TM1 Server.
- IBM Cognos TM1 Admin server
The Cognos TM1 Admin Server can be installed on any computer on your LAN but it must reside in the same LAN segment as your Cognos TM1 Server. Typically, the Cognos TM1 Server and the Cognos TM1 Admin Server are installed on the same computer.
- IBM Cognos TM1 server
The Cognos TM1 server can be installed on the same computer that hosts your Web server, but installing on a separate computer is more efficient.
The version of the Cognos TM1 server that is used in your Cognos TM1 Web environment must be equal to or more recent than the version of Cognos TM1 Web that you are running. If the version of Cognos TM1 Web you are running is more recent than the version of the Cognos TM1 server, users will receive an error when attempting to log in to Cognos TM1 Web.
