ODCI error with spatial operators

Hi group,
I get ODCI errors with spatial operators SDO_RELATE, SDO_FILTER and SDO_WITHIN_DISTANCE (not SDO_NN) called from JDBC (Java 1.2.2).
For example:
SELECT A.gid FROM FeatureTable1 A, FeatureTable1 B WHERE B.gid = 3 AND SDO_RELATE(A.Geometry, B.Geometry, 'mask=ANYINTERACT querytype = WINDOW') = 'TRUE';
Displays the error
ORA-29902: error in executing ODCIIndexStart() routine
Other functions such as SDO_AREA, SDO_NN work fine, though.
Both feature tables where populated with the SDOAPI toolkit and indexed using a fixed index.
I use a default full install of Oracle 8.1.6 on Linux RedHat 6.2.
What's wrong? Do I need to install anything else on the server?
Thanks for any advice.

Hi Dan,
There are several errors in the SampleNewToSDO.java sample. The outer polygons should be anti-clockwise, the inner polygons should be clockwise. Now that this is fixed, polygons (with or without inner polygons) do pass the validation test, but multipolygons do not.
What's wrong with this multipolygon:
double outerOrdArray1[] = {310, 310, 320, 310, 320, 320, 310, 320, 310, 310};
LineString outerLineString1 = gF.createLineString(outerOrdArray1);
double innerOrdArray1[] = {311, 311, 311, 319, 319, 319, 319, 311, 311, 311};
LineString innerLineStrings1[] = new LineString[1];
innerLineStrings1[0] = gF.createLineString(innerOrdArray1);
collection[0] = gF.createPolygon((LineString)outerLineString1,
(LineString[])innerLineStrings1);
double outerOrdArray2[] = {410, 410, 420, 410, 420, 420, 410, 420, 410, 410};
LineString outerLineString2 = gF.createLineString(outerOrdArray2);
double innerOrdArray2[] = {411, 411, 411, 419, 419, 419, 419, 411, 411, 411};
LineString innerLineStrings2[] = new LineString[1];
innerLineStrings2[0] = gF.createLineString(innerOrdArray2);
collection[1] = gF.createPolygon((LineString)outerLineString2,
(LineString[])innerLineStrings2);
geom = gF.createGeometryCollection(collection);
Note that the sdoapi java library does not detect anything wrong with the geometry (isValid() returns true even when the order of vertices is wrong).
Heterogenous collections are OK. Only multipolgons are wrong. To check whether the multipolygon was correctly stored in the table, I exported the table to XML using the SampleSDOtoXML.java sample. It looks good:
<MultiPolygon>
<Polygon name="0" srsName="0">
<LineString name="0" srsName="0"> <CList>310.0,310.0 320.0,310.0 320.0,320.0 310.0,320.0 310.0,310.0</CList> </LineString>
<LineString name="0" srsName="0"> <CList>311.0,311.0 311.0,319.0 319.0,319.0 319.0,311.0 311.0,311.0</CList> </LineString>
</Polygon>
<Polygon name="0" srsName="0">
<LineString name="0" srsName="0"> <CList>410.0,410.0 420.0,410.0 420.0,420.0 410.0,420.0 410.0,410.0</CList> </LineString>
<LineString name="0" srsName="0"> <CList>411.0,411.0 411.0,419.0 419.0,419.0 419.0,411.0 411.0,411.0</CList> </LineString>
</Polygon>
</MultiPolygon>
So why does SDO_GEOM.VALIDATE_GEOMETRY return 13050? Is there a special vertex ordering rule for multipolygons?
Thanks,
Jean-Pierre

  • Parrallel tables with spatial operators

    I have a point in polygon script that works, but in order to speed up the creation of the point table (~175M rows) I tried adding PARALLEL 4 and /*+ PARALLEL (t,4) */ Only the parallel part is new to the create point table sql.
    I used CTAS to create a point table like this:
    CREATE TABLE &OUT_POINT_SCHEMA..&OUT_POINT_TABLE NOLOGGING PARALLEL 4 TABLESPACE ORDERS_02
    AS
    SELECT /*+ PARALLEL (t,4) */
      cast(lpad(to_char(LON/1000000, '999.000000'),11) || lpad(to_char(LAT/1000000, '99.000000'),10) as varchar2(21))   ULL, 
      MDSYS.SDO_GEOMETRY(2001, 8307, MDSYS.SDO_POINT_TYPE(LON/1000000, LAT/1000000, NULL), NULL, NULL)    GEOM
    FROM
      &IN_POINT_SCHEMA..&IN_POINT_TABLE
    WHERE
      LON is not null
    GROUP BY
      LON, LAT;The spatial index was created like this:
    CREATE INDEX &OUT_POINT_TABLE._SIDX ON &OUT_POINT_TABLE (GEOM) INDEXTYPE IS MDSYS.SPATIAL_INDEX PARAMETERS('TABLESPACE=ORDERS_IDX WORK_TABLESPACE=ORDERS_03 LAYER_GTYPE=POINT');In theory, should the sql still work when I use, for example SDO_INSIDE? Or are there other things that I need to take into consideration? In other words, would the fact that the spatial point table was created with a parallel option impact spatial queries. When I try to monitor the process of the point in polygon sql with a check_session script (I am not a DBA) I see 4 rows with the same sql text which I assume is due to the parallel 4 parameter and I am also seeing wait_events like async descriptor resize and wait_time -1. Sorry to be so vague but I am trying to figure out if this query has a chance of finishing or if i broke it by adding the parallel option. Any guidance or suggestions would be appreciated.
    Thanks,
    David

    Yes, spatial operators (say SDO_INSIDE) can work in parallel queries.
    If you can show us your query explain plan, it will be easier to see
    how SDO_INSIDE is executed.

  • How to realize the function like SDO_GEOM.SDO_BUFFER in Spatial Operators?

    Dear all,
    I wanted to use SDO_GEOM.SDO_BUFFER function to generate a
    buffer polygon around a geometry object while it is pretty slow
    to perform for a large spatial database. I think it better
    to use Spatial Operators for it takes advantage of spatial index.
    But within operators, there are no availble function. Can anyone
    tell me how to do it with Spatial Operators?
    Thanks a lot,
    Fan

    Fabio,
    Error 13349 indicates that the polygons intersect with themselves.
    You need to fix these errors. There are tools in MapInfo Professional 7.5 to check and automatically fix them. There are other tools commercially available which also fix geometry errors.
    If you know MapInfo I would fix these errors there.

  • Use of several spatial operators in one select

    I am using Oracle 10g 10.1.0.2.0

    I want to check that the geometry of State and geometric union of corresponding counties is equal. I already found no very nice solution but cannot understand why in the following Oracle gives me an error of invalid identifier GU
    select S1.Name
    from State S1, (
    Select sdo_aggr_union(sdoaggrtype(C.Geometry, 0.005))

    where sdo_geom.relate(S1.Geometry, ‘EQUAL’, GU, 0.005)= ‘EQUAL’;

    Hi.
    If somebody is interested I found the solution. Conntact me if you want an explanation
    Select S1.Name

  • Best practice for use of spatial operators

    Hi All,
    I'm trying to build a .NET toolkit to interact with Oracles spatial operators. The most common use of this toolkit will be to find results which are within a given geometry - for example select parish boundaries within a county.
    Our boundary data is high detail, commonly containing upwards of 50'000 vertices for a county sized polygon.
    I've currently been experimenting with queries such as:
    select
    from
    uk_ward a,
    uk_county b
    where
    UPPER(b.name) = 'DORSET COUNTY' and
    sdo_relate(a.geoloc, b.geoloc, 'mask=coveredby+inside') = 'TRUE';
    However the speed is unacceptable, especially as most of the implementations of the toolkit will be web based. The query above takes around a minute to return.
    Any comments or thoughts on the best practice for use of Oracle spatial in this way will be warmly welcomed. I'm looking for a solution which is as quick and efficient as possible.

    Thanks again for the reply... the query currently takes just under 90 seconds to return. Here are the results from the execution plan ran in sql*:

  • Cannot view table with spatial advisor

    I have loaded a table using SafeFME software. It did not populate SDO_GEOMETRY.SDO_SRID during the conversion from ArcInfo coverage to Oracle8i Spatial SDO_GEOMETRY.
    Since I could not view the spatial data with the spatial advisor, I ran the VALIDATE_LAYER procedure and found the error. At that point I INSERTed a value for SDO_SRID into my table, and into XXXX_SDO_GEOM_METADATA. Still cannot view the spatial data with spatial advisor. Why not?

    Hi Dan:
    the Spatial Index Advisor message at the lower part of the apps' frame says 'Drew 3701 geometries' after I attempt to "Draw all geometries" (third button down on the left).
    After this, the viewport is blank. It is odd, though - it appears that the bounds are set correctly. When I add another "layer" and draw it, the viewport is referencing the correct area (the bounds for the first layer). This behavior occurs when the XXXX_SDO_GEOM_METADATA.SRID is either NULL or set to a value.
    Our MapXtreme app shows the same behavior (no display of data, no error message).
    I'll try to run the VALIDATE (layer and geometry) functions and procedures again.
    We have loaded some data with the routine using shp2sdo.exe (like in the tutorials) and those are drawing just fine. Strange.

    I've already installed data and created spatial indexes on other machine correctly with the same data with less memory use, and I can't find any difference.
    Could anybody help me?

    Andre,
    I didn't think the , and ; in the sdo_geom_metadata would be causing the problem because he indicated that he could build indexes on other data - I assume he uses the same diminfo values for these as well. But, one can never be too sure!
    But certainly, follow what the error messages indicate.
    The Oracle Error message manual says:
    "ORA-13232: failed to allocate memory during R-tree creation
    Cause: This feature assumes a minimum of 64K memory for bulk creation.
    Action: Create the index for a small subset of the data. Then, use transactional insert operations for the rest of the data."
    The spatial manual says:
    "Before you create a spatial index, be sure that the rollback segment size and the SORT_AREA_SIZE parameter value are adequate, as described in Section 4.1.1."
    One way to change the sort area size is to alter your existing session before
    executing the create index statement. So, from 4.1.1. this can be done via:
    ALTER SESSION SET SORT_AREA_SIZE = 20000000;
    Also, do what Andre suggests. On my laptop with 1G of memory as a matter of course I change the SGA from the default to being much larger.

  • SDOAPI and SPATIAL operators

    Hi, does anyone know if there is a java package that permits me to do some operations such as distance between 2 geometry SDO objects? I know there's sdoapi package that permits to create jgeometry objects, but it hasn't methods equivalent,for example, to within_distance operator of the spatial ...
    Another thing... are sdoapi and oracle spatial free or do i need a licence for them?

    Tnx

    Hi,
    SDOAPI and Locator (a large subset of spatial including all datatypes, indexes, and operators) are included with the database.
    SDOAPI allows you to call the server side spatial operators - they aren't implemented in the API.

  • Odd Error with decode function in Order By Clause

    I am trying to compile a procedure and can't get around an error with a dynamic order by that doesn't make much sense to me. I can repoduce the error with a plain select statment in sql plus so I can rule out a declaration error. Here is an example with 2 numeric columns and a date column.
    select task_id, display_date, remark_id from task_list
    where task_id > 1000
    order by decode('Task_ID', 'Task_ID',Task_ID, 'Display_Date', Display_Date, 'Remark_ID',Remark_ID)
    returns the error:
    select task_id, display_date, remark_id from task_list
    ERROR at line 1:
    ORA-00932: inconsistent datatypes: expected NUMBER got DATE
    I'm not sure why this error is occuring, because it doesn't even hit the Display_Date field in the Decode statment. If I take the Display_date out of the statement, it runs properly. If I change Display_Date to To_Char(Display_Date) it also runs fine, but the sorting is incorrect. Also I'm running 9.2, and do not want to use dynamic sql to build my query. Any Ideas out there as to the cause of this error?

    I did find a workaround to this issue by breaking the decode statment into three separate statement, but I still think that the way it is written above should work, and may be a bug, or an error that I don't understand fully.
    The Order by was rewritten like this:
    order by decode(pSort, 'Task_ID',Task_ID), decode(pSort, 'Display_Date', Display_Date),
    decode(pSort, 'Remark_ID',Remark_ID);

    2. Template file (RTF/PDF/..)
    XML data will not be created by the template file.
    We will be required to create XML data. One of the easiest way to create xml output is using the RDF. We can change the rdf output type in the concurrent program to XML.

    When i click con "perform" i get graphic errors.
    I have the same issue with the old Mainstage version since Mountain Lion.
    Also a fresh installation didn't help.
    I think i'm not the only one with this issue!
    I don't know how to report a bug?
    Perhaps someone can help me.
    (and  I'm probably not the only one (see feedback in Apple Store) If you also have this problem, please add a comment with your configuration (Hardware, Software))

    So, here an example how it looks like when i click on "perform":

    Same configuration,same problem. BUT I found a workaround.
    Mainstage has this error with the AMD video card and/or a second monitor connected.
    With a little app (http://gfx.io)  it's possible to really force the MBPro to use the Intel Graphics card.
    This will work only with the internal screen, not with a second screen connected.
    And sometimes you need to restart, to really make the Intel video card free.
    This works fine...In the meantime of a fix.
