IMPORTANT: Your TM1 System May Stop Working on Nov 25, 2016

Posted by Kevin Nichols on September 11, 2016

Important Notice for All IBM Cognos TM1 Users:

There is a possibility that your TM1 system may stop working on November 24, 2016.

The existing TM1 security certificates that are used in the Secure Sockets Layer (SSL) communications that occur between TM1 clients and servers are scheduled to expire on November 24, 2016. If your system is affected, your users will not be able to connect to your TM1 Server and use TM1 Web, TM1 Perspectives etc on November 25, 2016 unless you take appropriate action.

Is Your System Impacted?

If you are running TM1 version 10.X your system is most likely impacted as in versions 10.X the SSL settings are turned to ON by default. If you are running an older version of TM1 we recommend that a system review is performed to ensure continuity of service.

What should you do

IBM has created a new certificate that will replace the soon to be expired one and will provide even stronger encryption (2048 bit vs. 1024 bit). This new certificate has an expiration date of August 25, 2022 and needs to be installed to replace the existing one. The details for converting your TM1 environment to the new SSL certificate can be found in the following IBM Tech Note:

Please contact ACG at if you have questions, concerns or would like to discuss. We are happy to help review your TM1 system, confirm all updates are made properly and ensure TM1 system availability.
