First, you need to install SQLSERVER2005 or 2008, and then create a database with Alarm DB log manager. The default name is WWalmdb, so a database named WWalmdb is established in SQLServer. When intouch is running, the Alarm DB log Manger must also run to record historical alarms in SQLSERVER, and then use InTouch's own ALmviewDBctrl control to connect to WWalmdb and execute some simple scripts to query historical alarms.
