Check your SQL query setting the logging level to "geotools developer logging". I know we translate it to a long series of "pk = firstValue or pk = secondValue or ...", a "pk in (v1, v2, ...)" would be more compact, but any database worth its salt should realize the two are equivalent at the query planner level (but with Oracle one never knows) Cheers Andrea -- == GeoServer Professional Services from the experts!
