Error: Cannot get Map Layer Spatial Index Statistics for the layer
Running sdelayer -o si_stats on a DB2 layer returns the following error:
"Error: DBMS does NOT support this function (-1008).
Error: Cannot get Map Layer Spatial Index Statistics for the layer."
sdelayer -o si_stats is not supported with data stored in DB2.
Solution or Workaround
There is no solution. ArcSDE does not support this operation as the RDBMS (DB2) does not do so.
