Currently not many, so it looks like I might at the end ask client to add GlobalID manually. I was able to verify that command sdetable -o add_uuid_column -t M_SIGN_INVENTORY -u %USERID% -p %USERPASSWORD% -c GLOBALID
has nothing to do with GlobalID because everything in application, after I Sync Down feature layers is read-only which implies that GlobalId is not defined. Last thing to try is a python script:
# Import system modules
import arcpy
from arcpy import env
# Set workspace
env.workspace = "C:/Data/MySDEdata.sde"
# Set local variables
in_dataset = "AMS_AA.M_SIGN_INVENTORY"
# Execute AddGlobalIDs
arcpy.AddGlobalIDs_management(in_dataset)
Where AMS_AA is schema name, [M_SIGN_INVENTORY] is feature class name, the same as Oracle table. However, the scrip above fails with errorExecuteError: ERROR 000582: Error occurred during execution.
Failed to execute (AddGlobalIDs).
