When to use ArcGIS to change geodatabase schema?
Any number of shared locks can be established on a single feature class or table at any given time. When you use ArcGIS to modify your geodatabase schema—for example, to add a field or alter rules—ArcGIS attempts to establish an exclusive lock on the data being altered.
When does ArcGIS automatically acquire a shared lock?
ArcGIS automatically acquires a shared lock on an individual dataset when it is in use, for example, anytime a user is editing or querying the contents of a feature class or table. This mechanism is used so other users cannot make changes to the underlying dataset and its schema while it is in use.
