Session Timeout for TM1Web, PAW and PAX

August 5, 2020

We might often get a request from users that TM1 session has logged. As per the client requirement and standards, need to increase or decrease the session timeout. Changing the session timeout is a trade-off, it should not be too big or too small. If it’s too big then many inactive sessions can lead to server performance issues. If it is too small, then the user experience might be affected. 

Each application of TM1 has its separate session timeout parameter. Jump into the respective section, depending upon your need.


1. Go to <Installation Folder>\IBM\cognos\tm1_64\webapps\tm1web\WEB-INF\configuration and Open tm1web_config.xml file.
