How is an object lock used in ArcSDE?
Object locks are an application maintained locking mechanism exposed by ArcSDE. The geodatabase uses object locks to acquire shared and exclusive locks on version objects during editing and reconciling. The geodatabase acquires a shared object lock for a session on start editing.
What does the configuration keyword DO in ArcSDE?
The configuration keyword applies to ArcSDE data only. It determines the storage parameters of the database table. The Spatial Grid 1, 2, and 3 parameters are used to compute a spatial index and only apply to file geodatabases and certain workgroup and enterprise geodatabase feature classes.

Can a spatial index be re-created in ArcGIS?
Spatial indexes on feature classes in personal geodatabases cannot be updated or re-created. You can see what type of geometry storage is used for feature classes in enterprise geodatabases or databases by looking at the Geometry Properties section on the General tab of the Feature Class Properties dialog box.
Where do I find geodatabase lock in ArcGIS?
If you need to see who is holding a lock that is preventing you from altering the schema of a dataset you own or deleting a version you own, you can view a list of these locks from the Manage item on the context menu of the dataset.

How are States locked on the geodatabase?
States can be locked in shared or exclusive mode. The geodatabase acquires exclusive state locks for the new state during each edit operation. The exclusive lock prevents the state from being deleted or trimmed if the compress operation is executed. The lock is released by the geodatabase on the stop editing event.
How are the locks managed in the SDE?
