Is there a function in Oracle Spatial 11g to move/translate geometry?

Hello Everybody,
I am new to Oracle Spatial. I wanted to know if there is any function to move/translate a geometry in Oracle Spatial 11g? PostGIS has a function named ST_Translate to achieve the same.
Regards,
Shiva Shankar

Hi
There is an SDO_UTIL.AFFINETRANSFORMS function in the SDO_UTIL Package (Utility)
Note, that Simon Greener & Siva Ravada have published an excellent book ("Applying and Extending Oracle Spatial") that contains examples (in Chapter 7) of easy to use wrappers for this:

Oracle spatial 11g - 3D-Geometry and KML-Export

Hi,
I'm currently working with an Oracle Spatial 11g - database and there with 2d- and 3d-geometries. With this Version you can extrude 2d's to 3d's and calculate their volumes. This works fine.
The problem is to save the extruded areas as 3d-geometries in a specific table. Enclosed you will find the SQL-Code of the current workflow:
*1. Create tables for the 2d- and 3d-geometries (incl. metadata and spatial index)*
-- table for 3d-geometry
CREATE
TABLE ta_geb(
geom MDSYS.SDO_GEOMETRY
,area NUMBER(12,3)
-- metadata 2D
INSERT INTO USER_SDO_GEOM_METADATA (TABLE_NAME, COLUMN_NAME, DIMINFO, SRID)
VALUES
     'ta_geb',
     'geom',
MDSYS.SDO_DIM_ARRAY
(MDSYS.SDO_DIM_ELEMENT('X',4439900.00, 4440020.00, 0.005),
MDSYS.SDO_DIM_ELEMENT('Y', 5664050.00, 5664130.00, 0.005)
31468
-- spatial index 2D
CREATE
INDEX ta_geb_index ON ta_geb(geom) INDEXTYPE IS MDSYS.SPATIAL_INDEX;
-- table for 3d-geometry
CREATE
TABLE ta_3dgeb(
geom3d MDSYS.SDO_GEOMETRY
-- metadata 3D
INSERT INTO USER_SDO_GEOM_METADATA (TABLE_NAME, COLUMN_NAME, DIMINFO, SRID)
VALUES
     'ta_3dgeb',
     'geom3d',
MDSYS.SDO_DIM_ARRAY

     MDSYS.SDO_DIM_ELEMENT('Z', 0, 200, 0.005)
31468
-- spatial index
CREATE
INDEX ta_3dgeb_index ON ta_3dgeb(geom3d) INDEXTYPE IS MDSYS.SPATIAL_INDEX PARAMETERS ('SDO_INDX_DIMS=3');
*2. insert 2d-geomtry*

     SDO_NUMBER_ARRAY(10),
     'false', --validation
     0.005),0.005)
from ta_geb;
This works fine so far. Now I wanna insert the extruded geometry (now 3D) in the table ta_3dgeb. All my attempts were in vain...
*4. insert extruded geomtry*
INSERT
INTO
ta_3dgeb
select
SDO_UTIL.EXTRUDE(

          SDO_NUMBER_ARRAY(10),
          'false', --validation
          0.005)
from ta_geb;
I got the following error message after executing this Code:
ORA-29875: failed in the execution of the ODCIINDEXINSERT routine
ORA-13365: layer SRID does not match geometry SRID
ORA-06512: in "MDSYS.SDO_INDEX_METHOD_10I", line 709
ORA-06512: in "MDSYS.SDO_INDEX_METHOD_10I", line 225
Then I tried to change something on the metadata and spatial indices, wihtout success. Does anyone has advices to solve the problem??
Afterwards I would like to export the 3d-geometry in a KML file to visualize it in Google Earth. Therefore oracle provides a tool. But I didn't managed it to export the geometry. Any hints for the KML export or are there any other tools alternatively??
Thanks for any suggestions!
Regards

Extrude does not automatically populate the SRID for the resulting geometry as there may not be a 3D equivalent of the 2D SRID defined
in the DB.
So the extruded geometry comes out without the SRID. In your case, since you are creating an index on the ta_3dgeb table
before inserting the extruded data, it is causing this failure.
So drop the index on the ta_3dgeb table and do the inserts into it.
Then you can manually update the geometries with the SRID if there is a corresponding 3D SRID for 31468.
Otherwise, you can use 31468.

How Indexing function in Oracle UCM 11g

Hello All,
I am using Oracle UCM 11g on Windows platform.
I wanted to know as how the indexing in Oracle UCM Funtions? Here are few more questions related to this.
1. If multiple language characters are added in document and if document is indexed, then
how the data (tokens) will be stored in Database?
2. How the search will function

Hi
1. If multiple language characters are added in document and if document is indexed, then
a. how the data (tokens) will be stored in Database?
This is stored in the DB tables IdcColl1 or IdcColl2 ( if DB FullText is search indexer engine) and table would be IdcText1 or IdcText2(if OracleTextSearch indexer is used) . It is these tables that store the entire data from the contents and they are referred to / queried when a FT search is invoked from UCM .
b. how indexing will be done?
Indexer would extract all the data from the contents in case of FT indexer mechanism and would store them in the DB tables mentioned above . It is stored in BLOB columns where in the extraction process would do an insert for every content item that is being processed when Collection Rebuild Cycle / Automatic Update cycle is started .
2. What is settings to be done in Oracle and search engine for this?
For DB the relevant UCM scripts need to be executed so that the correct role are created and the packages are created.
3. What will be extra settings need to be done in case if the OS changes for example Linux.
The relevant libraries need to be checked to make sure that indexer can access them since there are lots of dependent libraries for the indexer process which is invoked by the TextExport process and these libraries vary for different OS . As part of the indexer process to be running fine all that needs to be done is to install/enable the OS specific versions of ContentAccess component on UCM .
Hope this gives an understanding on the Indexing part of UCM .
Thanks
Srinath

This error has nothing to do with Forms, it is an JavaScript error.
Most likely cause is this line

if (url.length > 0) {Or
if (url) { // not null checkCheers,

Oracle Spatial Object

I have more than 2 geographical points In USA saved in oracle DB using geometry object...
are there any function in Oracle Spatial Object that gives me the shortest route to go through all theses geographical points

You would need to create a network with all of your point geometries as nodes and lines as links. See...

Once you do that you can use it to solve your problem (traveling salesman).

Oracle Spatial functionality with WFS

Hi all
My first post here so be gentle on me ;-)
This may be an obvious question but here goes ...
When using a WFS client can you access the full SDO_... SQL functions within Oracle Spatial? I've had a read of the WFS spec and it is all a bit vague on how the queries get passed through to the data store.
Also with the WFS locking, is this done at the web server level? If so how would that impact on any direct access to the database? A bit dangerous??
Appreciate any advice on WFS implemtations with a 9i back end. I want to retain the full native Oracle functionality and still deploy via WFS ... a pipe dream??
Thanks
Richard

Thanks for your response Andreas
Sorry, perhaps I wasn't clear, I realise the WFS client will never directly access the data source, that it is the WFS server that makes the request to the data store, not the client, but can the call be passed through to Oracle as native SQL?
I think I found the answer in the OGC Filter Encoding Imp Spec where it desribes in great detail the optional filter component of a WFS request. It desribes the CQL filter operators that include some spatial operators. These could, I understand, be translated from CGL and Feature based schema to SQL (in GML?) and relational based schema.
While I don't think at first glance that the spatial operators in CQL match all the Oracle SDO_ functions they probably go far enough for most normal users.
Am I on the right track?
Does anyone know of any work that has been done in this filter translation to SQL and if it has been implemented successfully anywhere.
I think the locks would still pose a problem, but that's for another day :-)
Thanks
Richard

Oracle Spatial and Oracle Forms

Hi,
Does anyone have experience with Oracle Spatial and Oracle Forms?
I have generated a form, which is based on a view. The view uses the mdsys.sdo_relate operator. Somehow I am unable to get the form to perform (to get one record it takes over 20 minutes). While useing sql-navigator to process the same statement it seems no problem. The query that also uses the view, is then processed in 10 seconds.
I also noticed that when text-functions like ' lower' of ' upper' are used to query the view, the query is processed within 15 seconds. If I don't use ' lower' or ' upper' it takes a long time (> 20 minutes) to process the query. Is it possible that this causes the bad performance of the form?
On metalink I have found that forms and spatial do not cooperate because of the pl/sql version that
forms6 uses. There is no solution presented, does anyone know of a work around?
My configuration is:
Oracle 8.1.7 on WIN2K @ PIII-800Mhz 256 Mb memory.
Formsbuilder 6
If requested I can post the queries that I have made.
With regards,

Cost cutting requires reengineering spatial solutions to directly address business requirements. But enterprise computing for spatial data has, with even "Web 2.0", required the user to lose the responsiveness and feedback that traditional desktop thick client GIS software has provided. We took a different approach in the re-engineering effort and concentrated on making it work as much like a traditional desktop thick client - while simplifying use, making editing more reliable, and actually speeding up rendering. All this, while only supporting one versioned Oracle Spatial database, and application tier for all users.

Acquiring Oracle Spatial Data through WFS

Hi,
I have been researching for awhile and am slightly confused.
I have Oracle Spatial 11g with geometry data and would like to be able to retrieve that data through a WFS to serve to a viewing application.
Here's where I am confused:
1) Spatial has a WFS service which needs to be configured. If I were configure that, would I be able to access the data through URL getFeature commands? The documentation I see for them has the getFeature requests in the form of XML files so I am not sure if I can do that. Also it seems like the service is returning .log files but I think I would want GML...
If this is the option I should take, the tutorial to setup OC4J and the Web Services are for a Linux machine (http://www.oracle.com/technology/obe/11gr1_db/datamgmt/spatialws/spatialws.htm) -- Is there one for Windows 64bit?
2) Do I need another "application layer" to enable this URL support? I know MapServer can use URL requests.. can I just run this against the data in my DB and forget about the Oracle WFS?
3) MapViewer seems to work with WFS Themes and handle requests through Java and SQL.. is this another option?
I am basically confused as to where everything sits and what I should be focusing on to get my Spatial data out of the DB through a WFS. Any assistance on this matter would be greatly appreciated!
Thanks!

Any help debugging this issue would be greatly appreciated:
As per the documentation:
http://localhost:8888/SpatialWS-SpatialWS-context-root/wfsservlet?request=GetCapabilities&service=wfs&version=1.0.0
:this get request should return the capabilities info however I receive this error message instead in the browser:

Anything fixed in Oracle TopLink 11g Release 1 (11.1.1.1.0) ?

Was there anything fixed in Oracle TopLink 11g Release 1 (11.1.1.1.0) ?
I don't see anything in release notes ( http://www.oracle.com/technology/products/ias/toplink/doc/11110/relnotes/toplink-relnotes.html ) regarding fixes. Anybody know where I can get that info? We have run into a couple of issues in the previous 11g release (11.1.1.0.1) and want to know if those issues have been addressed in the new release.
Thanks!

The two major areas of work in 11gR1 (11.1.1.1.0) are enhancements to EclipseLink included with the its 1.1.1 release as well as enhancements around TopLink Grid (JPA-Coherence integration).
The EclipseLink 1.1.1 fixes are documented here: http://wiki.eclipse.org/EclipseLink/Release/1.1.1

Function in oracle to find number of occurances of a character in a string

hi,
is there any function in oracle to find the number of ocurrances of a character in a string ?
or is there any simple way of doing the same, rather than writting many lines of code as my program is already very complex.
Maria

Hi Maria,
I don't know of such a function in Oracle, but maybe you could use this:
length(search_string) - length(replace(search_string, character_to_be_found))
For example: select length('Hello') - length ( replace('Hello', 'l')) from dual;
Hope this is what you're looking for

Oracle bpm 11g Release

Hi,
Are there any news about oracle BPM 11g release? When it will be released (I heard early 2010). We are starting a new project and nnewd to decide weather to use version 10g or new features of version 11g.
Thanks,
Matej

Thanks for the links.
I was not aware of them. I've reviewed them,. They are pretty high level. We are looking for the documentation about integration with other applciations.
See for example:
How to listen to instance events in ALBPM
Thanks,
