The session inactivity timeout setting represents the amount of time a user can be inactive before the user’s session times out and closes. It only affects user browser sessions.
You can set the values from 5 minutes to 60 minutes.
This function has a default value of 30 minutes. You can set the value up to 60 minutes, however doing so might cause extra load on the system.
To change the value, follow these steps:
Select System administration > Setup > System parameters to open the System parameters page.
On the General tab, in the Session management section, enter a value in the Session inactivity timeout in minutes field.
If you set the value to greater than 30, you will be prompted to confirm your selection. The confirmation prompt says “Increasing the inactivity session timeout can cause extra load on your system, which can lead to a decrease in performance. Are you sure you want to continue?” The higher the value, the higher the load will be, which can affect negatively system performance. Select Yes to save the changes, or No to revert to the existing value.
