Changes to TM1 Web Deployment for Planning Analytics Local with the 2.0.55 Release

General Page

This document provides answers to frequently asked questions about the changes to TM1 Web in the 2.0.55 Planning Analytics Local release.
The IBM Planning Analytics Spreadsheet Service (TM1 Web) is delivered in a separate installation kit as of IBM Planning Analytics Local The first generally available version of the separate installation kit is 2.0.55. Before the 2.0.55 release, TM1 Web was provided in the Planning Analytics installation kit that also included TM1 Server, TM1 Applications, and the TM1 Client tools.

Why is TM1 Web now in a separate installation kit?

There are a number of reasons for this change. There is a dependency between the versions of TM1 Web and Planning Analytics for Microsoft Excel. New features and capabilities developed for Planning Analytics for Microsoft Excel require an update to TM1 Web to support. This change allows for updates to TM1 Web to be delivered in parallel with updates to Planning Analytics for Microsoft Excel.

Does this change impact customers using Planning Analytics on IBM Cloud?

No, this change only impacts Planning Analytics Local customers that are updating to TM1 Web 2.0.55 or IBM Planning Analytics

Where can I find details about defects (APARs) resolved in each release of TM1 Web?

See the Planning Analytics Spreadsheet Service fix list available from

What if TM1 Web is already installed as part of the same installation as my TM1 Server (TM1 Server and TM1 Web installed in the same directory on the same computer)?

TM1 Web will be installed into a separate directory. The IBM Cognos TM1 service that ran TM1 Web on Windows will be stopped and set to manual startup. A new service named IBM Planning Analytics Spreadsheet Service will be added. The existing configuration (memory sizing, SSL, etc) will be copied from the existing install to the new install. The service is set to automatically start, but is not started as part of the installation. This allows you to make any desired configuration modifications before starting the service for the first time. After that, the service will automatically start upon system restart or any other event that starts services.

What if my old IBM Cognos TM1 service is used to run TM1 Applications (pmpsvc)?

If the IBM Cognos TM1 service is used to run TM1 Applications (pmpsvc) then it must be reconfigured and re-enabled.

What if my TM1 Web is installed on a different system then the TM1 Server?

The new installation kit does not require TM1 Server, or any other Planning Analytics software components, to be installed on the same system.

Is TM1 Applications (pmpsvc) also moving to a different installation kit?

No, TM1 Applications remain as part of the long cadence delivery. The IBM Planning Analytics team does not plan on moving TM1 Application at any point.

What if I want to install TM1 Applications (pmpsvc) on the same system as TM1 Web, or TM1 Applications is already installed on a system where I'm installing TM1 Web 2.0.55?

If TM1 Applications and TM1 Web 2.0.55 are installed on the same system they will each need unique port numbers. TM1 Applications and TM1 Web 2.0.55 each need to be installed in their own directory.

My current TM1 Web is configured to use SSL (HTTP). How do I move my existing SSL implementation to the new TM1 Web stand-alone installation?

If TM1 Web 2.0.55 is installed on a Windows Server that contains an older TM1 Web installation, the SSL configuration from the existing TM1 Web installation will be automatically migrated.

How do I set up SSL (HTTPS) for the new TM1 Web stand-alone install from scratch?

Can I use Cognos Configuration to install and configure the TM1 Web 2.0.55?

Cognos Configuration is not provided with the TM1 Web 2.0.55 stand-alone installer. Installation of the TM1 Web service on Windows Server is performed as part of the TM1 Web 2.0.55 installer. Configuration of TM1 Web 2.0.55 is based on updating configuration files.

Where can I find the documentation to install and configure TM1 Web using the stand-alone installer?

What operating systems is the stand-alone TM1 Web 2.0.55 installer supported on?

There are installation kits for both Windows Server and Linux. A detailed list of supported operating systems for all IBM Planning Analytics components is available from the Software Product Compatibility Report. See:

The minimum suggested requirement for a system running TM1 Web is 4 CPU cores and 8 GB of RAM. The default memory allocation for the JVM heap size for TM1 Web has changed from 1.5 GB to 4GB. The actual memory required to run TM1 Web depends on the number of users, and design of Websheets.
