What Is the Session Timeout Period of DataArts Studio? Can the Session Timeout Period Be Modified?
If you do not perform any operations within the specified duration, the session becomes invalid, and you must log in the system again.
The session timeout policy can be set in the IAM service, as shown in the following figure.
The session timeout policy is enabled by default and cannot be disabled. The administrator can set the session timeout period, which ranges from 15 minutes to 24 hours and the default value is 1 hour. This policy takes effect for the account and IAM users of the account.
