How to change the Z Resolution of a feature dataset?

Question

is there a way to change the Z Resolution of a feature dataset? I think that I can do this by creating a new feature dataset with the correct Z Resolution, and then load all of the data into new feature classes in the new feature datsaet. However, this database currently has a bunch of data in it, with multiple users editing data in multiple versions, which I'd like to preserve, so I'm looking for a way to simply re-define the Z Resolution. I'd even be OK with having to re-poplulate the Z values, as this wouldn't be too hard.

Thanks,

Jon.

The problem was that the user that I was using to connect to the enterprise geodatabase was not the owner of the feature dataset. Once I connected to the enterprise geodatabase using the DBO user, then I was able to change the Z resolution.

An updated code sample which gets a schema lock on the feature dataset, and sets the Z resolution directly, is shown here:

IGeoDataset geodataset = datasets.Next() as IGeoDataset;
           
            // retrieve and modify spatial reference
            ISpatialReferenceResolution spatialReferenceResolution = (ISpatialReferenceResolution)geodataset.SpatialReference;
            spatialReferenceResolution.set_ZResolution(false, 0.001);

// acquire schema lock
            ISchemaLock schemaLock = (ISchemaLock)geodataset;
            schemaLock.ChangeSchemaLock(esriSchemaLock.esriExclusiveSchemaLock);

// apply modified spatial reference
            IGeoDatasetSchemaEdit geoDatasetSchemaEdit = (IGeoDatasetSchemaEdit)geodataset;
            if (geoDatasetSchemaEdit.CanAlterSpatialReference)
            {
                geoDatasetSchemaEdit.AlterSpatialReference((ISpatialReference)spatialReferenceResolution);
            }
