If you are juggling multiple geodatabases - test, production, and development instances, personal and file geodatabases containing extracted data, etc. - then you know the importance of connecting to the right geodatabase before making any changes. When you start ArcMap, the ArcFM login screen is the first thing that appears, allowing you to specify which geodatabase you are connecting to, in order for that geodatabase's unique configuration of functionality and rules to be in effect as you work.
After you begin working in ArcMap, if you later need to login to a different geodatabase you can reopen the ArcFM login screen without restarting ArcMap. On the ArcFM toolbar, click the Login to ArcFM button. When the Login to ArcFM dialog appears, browse to the desired geodatabase.
Because the layers currently in your map still point to data in the previous geodatabase, it is usually wise to apply a Stored Display immediately after logging into a different ArcFM geodatabase. The Stored Items lists will always show Stored Displays, Page Templates, and ArcFM Documents from the geodatabase you are currently logged into, not from any previous connection.
You can login to a different ArcFM geodatabase as often as you want and at any time, as long as you are not editing.
