Each GeoRaster object must have an associated raster data table whose name is unique among raster data table names in the database. If the GeoRaster object is not empty and not blank, the raster data table must exist, be visible in the current schema, be defined in the same schema as the GeoRaster data table, and be an object table of SDO_RASTER type. However, one or more of these requirements were not met.
Check the rasterDataTable specification and ensure that all relevant raster data table requirements are met.
