The database server logs the information in a text file called login_history.txt. This file is stored in <server_data_folder>\v6data\logs.
On Windows, the ServerData entry in the registry points to the location of the server data. The default location of the ServerData entry is HKEY_LOCAL_MACHINE\SOFTWARE\Telelogic\DOORS_Server\9.5\Config.
On Solaris, the login_history.txt file is stored in $SERVERDATA/v6data/logs.
To show the login history, open the login_history.txt file in a text editor.
