That is, if two stand-alone feature classes are related via a relationship class and a process accesses one of them, both feature classes lock. Locks apply to both sides of a relationship class.A process accessing a feature class within a feature dataset locks all the feature classes in the feature dataset.Accessing a dataset also locks additional related datasets as follows: When a process accesses a dataset, it locks the dataset, preventing other processes from modifying it. If you close the map and try again, you can delete the feature class, provided there are no other processes accessing the data.
ARCGIS FILE GEODATABASE LOCK PRO
For example, if you have a feature class displayed in a map in ArcMap or ArcGIS Pro and attempt to delete the same feature class from the geodatabase, you will get the following message: Failed to delete selected object(s)Ĭannot acquire a schema lock because of an existing lock. Once the other process terminates, you can again perform these operations. However, ArcGIS prevents you from performing any of these operations if another process is already accessing the data, whether it be a process on your computer, another computer, or a service. You can also delete, compress, or decompress the dataset.
If you are the only person working with a dataset in a file geodatabase and are accessing it via one process only, you can freely edit or modify its properties.
