IBM Cognos TM1 Certificate Expiry - FAQ

Question & Answer


On November 24th 2016 the bundled/default/pre-configured TM1 SSL certificate will expire (APPLIX certificates). This means all connections to the TM1 Server will be refused hence causing a perceived major outage. TM1 has historically bundled certificates to make certain every client has SSL enabled and communication between clients and the data server are secured. This is against the norm in that most vendors have transferred ownership of SSL Configuration to their customer base. The TM1 team has taken a different view of simplifying the ability to have secured communication while allowing for customer owned custom certificates to be used as well. This ensures all of our customer regardless of skill level and understanding will achieve secure communication. While this is a very good thing, once every 10 years the certificates expire and we are forced to react quickly to prevent a mass outage. The team has been working hard to ensure the best possible experience for customers prior to certificates expiration. This FAQ has been compiled with anticipated questions and answers, to help customers understand, resolve and prevent expiring certificate issues.

The pre-contained certificates provided by IBM are self-signed, typically with a 10yr life span.

The APPLIX certificate was created on Nov 27, 2006 whereas encryption methods have evolved greatly since that time

    • Open Cognos Configuration (for TM1)
    • Click on the 'TM1 Admin Server' entry and in Explorer pane
    • Look at the 'Certificate File Location' parameter

      • If blank, you WILL be affected by the SSL certificate expiry
    • Look at the 'TM1 Admin Server Certificate Version'
