TM1 Web architecture

IBM® Cognos® TM1® Web uses a multi-tiered architecture that enables users to access and interact with TM1 data using any supported web browser.

The IBM 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 TM1 data using any of the supported web browsers. Users can work with TM1 cubes and TM1 Websheets.

For an updated list of environments that are supported by TM1 including information about operating systems, TM1 servers, and databases, create a detailed system requirements report using the Software Product Compatibility Reports tool (https://www.ibm.com/software/reports/compatibility/clarity/index.html).

Tier 2: Web server

TM1 Web runs on a Java-based web server.

This tier provides support for converting and displaying Microsoft Excel worksheets as TM1 Websheets. This service also exports Websheets back to Microsoft Excel and PDF formats.

Tier 3: Data

This tier includes the TM1 Admin Server and at least one TM1 Server.

IBM TM1 Admin server: The TM1 Admin Server can be installed on any computer on your LAN but it must reside in the same LAN segment as your TM1 Server. Typically, the TM1 Server and the TM1 Admin Server are installed on the same computer.
IBM TM1 server: The 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 TM1 Server that is used in your TM1 Web environment must be equal to or more recent than the version of TM1 Web that you are running. If the version of TM1 Web you are running is more recent than the version of the TM1 server, users will receive an error when attempting to log in to TM1 Web.
