Re:LOB, Spatial data

Hi all,
can any one tell me that does goldengate support LOB and spatial data? if so do we have to add any parameters to the parameter file in the goldengate?
thanks in advance..

Hi
I hoppe this help you:
----- Supported data types Classic Capture
**Basicfile LOB columns
LOB modifications done via
DML
(INSERT/UPDATE/DELETE)
are captured from redo.
◆ LOB modifications done via
DBMS_LOB package are
captured by fetching values
from the base table.
*** Securefile LOB
◆ Securefile LOBs are only
captured from redo if LOBs are
not transformed (such as not
compressed or encrypted) and
stored out of row, and if the
modification is done via DML
statements.
◆ LOBs are fetched from the
base table for the following
cases:
◆ LOB is encrypted
◆ LOB is compressed
◆ LOB is stored in-line
◆ LOB is modified via
DBMS_LOB package
◆ LOB is deduplicated
◆ LOB is modified via
fragment operations
◆ NOLOGGING LOBs

Anyone have on opinion on the usage of SECUREFILE LOBs for spatial data?

Hi folks,
From everything I read the usage of SECUREFILE LOBs over BASICFILE LOBs appears to be a nobrainer.
http://www.oracle.com/technetwork/database/options/compression/overview/securefiles-131281.pdf
Yet the default table creation remains set to create BASICFILE LOBs so my 11g spatial data is still sitting in BASICFILE LOBs (also I need to push it to and from 10g for the moment).
Should we all be changing over to SECUREFILE LOB storage as a matter of course on 11g? Is there a big payoff for VARRAY storage beyond compression? A little payoff?
Oracle says SECUREFILE LOBs "dramatically improve performance". Hey, I want some of that!
http://www.oracle.com/newsletters/sap/products/database/oradb11g-features.html
But yet there just has not been much traffic on the topic.
Pro Oracle Spatial mentions weakly on page 250 that
"Secure File LOBs are expected to be faster than BASIC LOBs".
but seems to only be referring to the spatial index.
Here Godfrind says to use them with points clouds but only trumpets the compression aspect.
http://www.ncg.knaw.nl/Studiedagen/09PointClouds/presentations/PointCloud_14_AlbertGodfrind.pdf
For those of us using ArcSDE, its pretty easy to add the SECUREFILE LOB keyword to the dbtune keyword that governs creation of the spatial column. But not a peep on the topic from the ESRI folks that I can find.
Anyone have any experiences or opinions to share? I am hoping to finally leave 10g behind one day this year and putting together a migration plan. Should converting the LOBs be a first day bullet item or just something to consider sometime down the road?
Thanks!
Paul

I have been writing on the benefits of rounding ordinates on storage and performance.
That series has not yet been finished and fully published but my main finding (backed by stats/graphs) is that rounding ordinates does have an effect on performance as average coordinates per feature increases.
As part of the work I also looked at SECUREFILE LOB storage in the hope that some sort of zlib/rle etc compression of the sdo_ordinates would substantially reduce storage size and thus increase performance.
The reason I looked at this is because a customer has migrated from SDEBINARY to SDO_GEOMETRY (though most others are going from SDEBINARY to SDE.ST_GEOMETRY) and saw a substantial increase in storage costs. They also have taken a performance hit in some aspects of their operations but that may be due to ArcSDE programmer SDO_GEOMETRY access issues rather than any real issues with Oracle performance (though the perception is very much that Oracle is to blame). SDEBINARY was always a compressed storage format and with SDE.ST_GEOMETRY being WKB (of some description) also has a low storage footprint.
The result of my work on LOB storage, though not published, is that I agree with Paul: there is little benefit for a lot of pain.
However, I do still the whole question of storage size as being an area of benefit if reductions could be made as this is a necessary precursor for spatial being able to reap benefits if column-oriented storage ever migrates down to standard Oracle database.

How to load spatial data from .shp file

Could anyone suggest an easy to use, free tool to upload spatial data from .shp file (or/and other open source spatial file sources) into an Oracle Locator database?
We have licensing for ArcGIS10, but nobody (including ArcGIS) have been able to successfully create a direct connection from their software to our Oracle 10.2 database.
Client desktops here are Windows 7 64bit, which further complicates matters (tend to find neither ArcGIS nor Oracle support 64bit OS in a cogent fashion)

790951,
. . . .You can also try Oracle's ShapeFile Converter (shp2sdo). It's a command line utility so there's automation potential.
. . . .Note that ESRI's tools may (depending on how they're used) store spatial content in Oracle Spatial as BLOBs containing their ST_GEOMETRY data-type (rather than Oracle's SDO_GEOMETRY type).
Regards,
Noel

Can you try SDO_GEOM.VALIDATE_GEOMETRY_WITH_CONTEXT
or SDO_GEOM.VALIDATE_LAYER_WITH_CONTEXT? e.g.
select * from base_sdo a where
SDO_GEOM.VALIDATE_GEOMETRY_WITH_CONTEXT(a.CA, 0.000005) != 'TRUE';

Retrieving spatial and non spatial data in one query

Hello. I am having slight difficulties using JDBC to retrieve both spatial and non spatial data in the same query. The following is code from a sample program of mine that retrives spatial data from spatial tables.
(In spatialquery geom is a geometry column and city is simply the name of the city):
try
Geometry geom = null;
String database = "jdbc:oracle:thin:@" + m_host + ":" + m_port + ":" + m_sid;
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
con = (OracleConnection)DriverManager.getConnection(database, sUsername, sPassword);
GeometryAdapter sdoAdapter =
OraSpatialManager.getGeometryAdapter("SDO", "8.1.7", STRUCT.class, null, null, con);
String spatialquery = "SELECT a1.geom, a1.city \n" +
"FROM cities a1";
Statement stmt = con.createStatement();
OracleResultSet rs = (OracleResultSet) stmt.executeQuery(spatialquery);
int i = 0;
int noOfFeatures = 2;
while (rs.next())
for(i = 1; i <= noOfFeatures; i++)
STRUCT dbObject = (STRUCT)rs.getObject(i);
try
geom = sdoAdapter.importGeometry(dbObject);
catch(GeometryInputTypeNotSupportedException e)
System.out.println("Input Type not supported");
catch(InvalidGeometryException e)
System.out.println("Invalid geometry");
System.out.println(geom);
}//end while loop
This retrieves the sptial data fine, however when I attempt to retreive the non-spatial data I keep getting a "ClassCastException" error. I understand it is something to do with "STRUCT dbObject = (STRUCT)rs.getObject(i);" line. Can anyone tell me how to retrieve both spatial and non-spatial data in the one query using JDBC. I have tried nearly everything at this stage. Cheers joe

Best Practice for Storing Spatial Data in Multiple Projections?

From what I've been able to determine MS SQL can't do reprojections is that correct? Assuming it is, the state of Washington requires that our GIS data be managed in Washington Stat Plane South
but for our web mapping sites need the data in Web Mercator. Is it OK then to have two geometry columns in a spatial enabled table, say a county table, one in WSPS and the other in WM?
I’m coming at this from a 30 year background in GIS using ESRI software.
Usually we would store the shape / geometry in one projection and project it to other on the fly when needed.
That way there is only one definitive source. I don’t see a way to do this in MS SQL.

Hi Scott.
Storing two columns of spatial data is fine in SQL Server. And you are correct that there is no built-in reprojection in SQL Server, most folks do that as part of data loading. There was talk of porting parts of ogr2ogr to SQLCLR, but I don't think anyone
did that.
Cheers, Bob

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:

DISPLAY SPATIAL DATA USING JDBC ON A JAVA FRAME

I am trying to set up some spatial data and need help in getting some sample
code for displaying the data on a Java Frame using JDBC.
The shapes I am setting up are simple polygons, lines, circles. I was going
through the samples in the demo directory under $ORACLE_HOME/md/demo/examples, but could not find any JDBC
I would really appreciate if you can point me towards some sample code and any other spatial resources.
Madhukar

Here you go. It uses JDBC to fetch geoms, convert them into Java JGeometry objects, which then create Java2D shapes (these are functions of the public sdoapi.jar library). It then uses some class in the sdovis.jar library (the rendering engine of MapViewer) to setup the necessary viewport transform. If you know how to setup the viewport transform, then you dont even need sdovis. sdovis.jar is found in an deployed MapViewer's WEB-INF/lib directory. Or you can extract it from the mapviewer.ear's web.war file.

Conversion of .dgn file to .shp files for spatial data processing

Hi All,
Presently I am working oracle spatial database (10gR2). I have following task:
Task: Spatial data loading into oracle database 10g Release 2:
Task process description: Client has given the input file as with .dgn extension. So we have to convert that to .shp file and load to spatial database.
There is utility in OTN site for loading data .shp file data into spatial database. This we can able to do.
Now I am looking for how to convert the .dgn file to .shp file? I mean, if there is any tool for it or any commands to do this in specific environment.
Any help would appreciate.
Thanks,
[email protected]

Hi,
There are several ways to do this.
Get a general GIS format translator. I use FME. This can be obtained from SAFE at safe.com. There is a free 30 day evaluation.
Get GIS software which has a data translation facility. Take your pick of the systems.
Write some code to read the DGN into Oracle. The DGN format can be found at http://www.bentley.com/en-US/Products/MicroStation/OpenDGN/. You need to know the version of DGN.
Ask your client to supply data in SHP format.

Oracle 11g R2, Problem Loading Spatial Data

We have a geodatabase which has been implemented by oracle spatial. it has been working quite fine since 2 years ago. Recently the data center serving our geodatabase has been upgraded on both software and hardware specifications. The handler application now has difficulty retrieving spatial data. The problem is somehow strange; only some spatial objects are loaded and then application encounters exceptions.
Previous working database engine was an Oracle 11g R1 and the new one is Oracle 11g R2. The application is a java application mostly written by swing. Here is the stack trace:

I read in some forums that the problem could be caused by jdbc version incompatibility, so I just copied jdbc archives from the installed oracle 11g R2 jdbc folder but the problem persists. Last thing I should mention is that only spatial data is problemistic and non-spatial data is easily loaded.
Please Help, Thanks.

Hi storm,
During the installation of oracle as you said if you have given the global password, basically this specific password will reflect to users such as
-sys
-system
-dbsnmp
-sysman
As you are new to oracle the basics that you should know is that "SYS" user is the highly privileged user in Oracle and should be logged in as "sys as sysdba" with his respective password (i.e. the global password that you have entered during database installation) to obtain his privilege. Remember to manipulate your database with caution when you are logged in as the sys user. You can log into the database using the sys user in the following way:
c\> sqlplus sys as sysdba
password: ****** --It will ask you for the password and you will have to give the global password that was given during installation
Hope this helps!!!
Regards,

Keep the Oracle Spatial data in memory

I can keep any database tables in memory (for fast access) using Oracle Coherence (the In Memory Data Grid).
Now I want to store Oracle Spatial data in memory, is it possible?

I think it is possible. The difference is it is not easy to recreate some Spatial-related functions and procedures in caches. But you can invoke them from the in-memory applications using Oracle Spatial Java API.

Cannot edit Oracle Spatial data

Hello,
I am running into some problems with my Oracle Spatial data. Maybe somebody has some insight. Here's what is going on:
1) I am able to connect to and view the data in uDig but I cannot edit the data and also the data shows up in the table of contents with a line symbol even though it is polygon data (it renders correctly in the map as polygons). I try using the 'Create Polygon Geometries' tool and it errors saying 'Create Polygon Tool' cannot operate on current layer.
2) When I try testing edits through WFS-T it errors and tells me that the table is read only.
The table is in the USERS tablespace and I have verified that it is read/write. I also set object permissions on the user: ALTER, DELETE, INSERT, SELECT, UPDATE
Am I missing something obvious? Anyone else have this problem? Thanks a lot for any ideas anyone has.

My apologies for the confusion. My insert statement DID work just fine. I just wasn't seeing it...probably because I was querying the table in Enterprise Manager DB Control and it looks like it takes some time to refresh. So it appears that user permissions are not the issue.
I have used two data loading methods:
Before loading data, I needed to create a user defined coordinate reference system:
1 create projection operation for my custom projection
2 configure projection parameters
3 create the projected CRS in mdsys.sdo_coord_ref_system
First data load steps
1 shp2sdo.exe my_shapefile my_table -g geom -s 1000002 -v
2 execute my_table.sql
3 execute sqlldr.exe
4 EXECUTE SDO_MIGRATE.TO_CURRENT('my_table','GEOM');
5 CREATE INDEX my_table_index ON my_table(geom) INDEXTYPE IS MDSYS.SPATIAL_INDEX;
Second data load steps:
1 open up MapBuilder, make a connection, and go through the Import Shapefile wizard. MapBuilder automatically creates a spatial index.
Does it appear that I am missing any steps or doing anything obviously wrong that would be causing me to not be able to edit the data through clients such as uDig or WFS-T?

Oracle Content Management for spatial data

Hi,
Is it possible to use Oracle universal content management sofware for managing GIS files/spatial data.
Can we integrate Oracle Universal content management or anyother tool to manage spatial files. I am looking for standard content management features like login/chekin/checkout/security/previes for spatial files etc..
Thanks

Controlling access to Oracle Mapviewer spatial data through VPD

I am building a web GIS application in Oracle Application Express (APEX) and have used the Virtual Private Database feature of Oracle Database 11g Enterprise Edition so as to ensure row level security. I've integrated APEX with Oracle Mapviewer through Oracle Maps API in order to display a map.
VPD feature is working properly through the command prompt at the database level but I also need to use the VPD policy at the application level so that each authenticated user can only see his own spatial data on the map.
So far I have accomplished that by creating as many data sources as the number of application users on the mapViewerConfig.xml file. Every time a user logs in the web GIS application, the correct data source is being employed.
I was wondering if there is any other parameterised way that I can perform this access control functionality without having to create all these data sources.
Many thanks in advance.

Yes you can define a single "secure" MapViewer data source to achieve VPD or make use of your database VPD setup. For more details and how to get the Apex app user to MapViewer and then onto VPD you can check out my blog post here: http://oraclemaps.blogspot.com/2008/09/apex-oracle-maps-and-secure-mapping.html
hope this helps,

Spatial Data in distributed environment

Hi,
I have some question regarding holding spatial data:
1- Is any interchange possible between spatial data via DB Links
2- is it possible to hold spatial data in distributed environments/different instances for several purposes so that a general application has an access via DB Links to each instance (different spatial data)

You can fetch data via dblink. You cannot put data across a dblink.
You cannot use spatial operators with data across a dblink (for instance, find all the geometries on a remote system that have some interaction with a user-specified query window).
