Managing sessions timeout

To manage sessions timeout, Arc uses the HTTPSessionTimeoutMinutes parameter of the tm1s.cfg. This parameter sets the timeout authentication of TM1 REST API queries.

This parameter is defined per TM1 servers, the default value is 20 min.

To increase the timeout to 40 min for a specific instance, open the tm1s.cfg and add the new parameter HTTPSessionTimeoutMinutes=40. A server restarts is not necessary as this parameter is dynamic.
