How to Configure Planning Analytics Timeout Settings

How to avoid the time out for users of TM1?


CA11 (Cognos BI) should have the lowest time out, e.g. 3600 seconds as default. This gives
CA Session timeout  < PAW Session Time-Out , should then have SessionTimeout= 60m and ProxyTimeoutSeconds=900 (15 min)
< TM1 Web in \tm1_64\webapps\tm1web\WEB-INF\web.xml at <session-timeout>70</session-timeout> & TM1 Web Applications timeout in Cognos Configuration > TM1 Applications set to 70 for Session timeout (default is 60 min).
< TM1 Database timeouts (tm1s.cfg settings IdleConnectionTimeOutSeconds= 4800, and a Rest-API connection HttpSessionTimeout= 80.)
< IIS timeout settings on the Windows server for CA gateway.

Session timeout in Cognos Analytics

1. Launch Cognos Configuration and navigate to “Local configuration -> Security -> Authentication”

2. Modify the “Inactivity timeout in seconds” from the default 3600 to your desired time (for example 7200 = 2 hours”).

3. Save the configuration and restart the Cognos service for the changes to take effect


  • Most web server timeout settings will come into effect long before the 1 hour time limit, but in the even that no such timeouts exist, this setting acts as a backup.
  • Furthermore, if the web server hosts other sites that do not have such a timeout, the Cognos portal can be secured by setting this to a shorted time frame so that only Cognos users are affected
  • The Cognos timeout is set to a value that is less than the timeout set on in-built portal. Make sure you set the value of “Inactivity timeout in seconds” in Cognos configuration to a value which is greater than the Inactivity timeout of your in-house portal.
