Re: [Geoserver-users] Oracle View Problem
Also see this page, which gives a good example of using the function-based index technique: http://gis.stackexchange.com/questions/92554/can-i-create-an-oracle-spatial-view-from-a-non-spatial-table That page also mentions the possiblity of defining a *materialized view* on the underlying table, which should be able to support a spatial index directly.

Re: [Geoserver-users] Oracle View Problem
Have you tried creating a spatial function-based index on the table? http://docs.oracle.com/cd/E11882_01/appdev.112/e11830/sdo_exten.htm#SPATL799 See the example 9.2.1 - it creates a function creating the geometry out of the X,Y values, and then uses that for indexing and querying. Hopefully it's possible to define a view hiding the existence of the function, but still using the spatial index. In this case, GeoServer might be able to query the view (using SDO_FILTER as per normal) and Oracle will support the query since it can use the index. Ironically, in my experience when working with tables containing XY data, it's at least as fast to simply use normal B-tree indexes and range queries. However, it doesn't sound like this can be made to work in GeoServer (yet...)

Re: [Geoserver-users] Oracle View Problem
Hi Alper, nope, as far as I know, the problem is still there, known issue, we cannot query data that does not have a spatial index: https://osgeo-org.atlassian.net/browse/GEOT-4768 Some development is needed to recognize the source has no spatial indexes, and change the spatial operators we use for bbox queries Cheers Andrea On Wed, May 13, 2015 at 4:10 PM, Alper Dinçer wrote: > Hi, > > We have a table that includes X and Y columns for latitude and longitudes. > We created a view with geom column from this table as follows : > > (SDO_GEOMETRY(2001, 4326, SDO_POINT_TYPE (ST.Y, ST.X, NULL), NULL, NULL)) > > Then we published this view from GeoServer and try to get the WMS request. > > The WMS request has following error : > > ServiceExceptionReport SYSTEM " > http://172.16.1.139:8084/geoserver/schemas/wms/1.1.1/WMS_exception_1_1_1.dtd";> > code="internalError"> > Rendering process failed > java.io.IOExceptionORA-13226: interface not supported without a spatial > index > ORA-06512: at "MDSYS.MD", line 1723 > ORA-06512: at "MDSYS.MDERR", line 8 > ORA-06512: at "MDSYS.SDO_3GL", line 88 > > > > As far as I searched, this was a problem in Oracle 9, but we are working > on 11g. > > How can we get rid of this error?

[Geoserver-users] Oracle View Problem
Hi, We have a table that includes X and Y columns for latitude and longitudes. We created a view with geom column from this table as follows : (SDO_GEOMETRY(2001, 4326, SDO_POINT_TYPE (ST.Y, ST.X, NULL), NULL, NULL)) Then we published this view from GeoServer and try to get the WMS request. The WMS request has following error : http://172.16.1.139:8084/geoserver/schemas/wms/1.1.1/WMS_exception_1_1_1.dtd";> Rendering process failed java.io.IOExceptionORA-13226: interface not supported without a spatial index ORA-06512: at "MDSYS.MD", line 1723 ORA-06512: at "MDSYS.MDERR", line 8 ORA-06512: at "MDSYS.SDO_3GL", line 88 As far as I searched, this was a problem in Oracle 9, but we are working on 11g. How can we get rid of this error? There was no luck with creating spatial index on views. Best.
