What does the error message “the coordinates defining an arc are not distinct” mean (SYNC-2811)?
This is actually an Oracle error message: “ORA-13347: the coordinates defining an arc are not distinct” and causes the geometry to get set to NULL in the database (the rest of the record is present in the database). The cause is the difference between the units in Smallworld and Oracle, most likely, Smallworld uses milimeters, Oracle uses meters. After conversion, double coordinates are generated and Oracle doesn’t like this. At the moment, the source data needs to be fixed for this.
