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.

Keep Oracle spatial data in memory

Can I keep Oracle Spatial data (including metadata and related functions and procedures) in memory using TimesTen?

It depends what form the data takes. TimesTen does not support any spatial types, only regular relational data types. Also, TimesTen does not support any of the Oracle spatial functions.
In general this is not possible.

Keep Oracle Spatial data in Coherence Caches?

Can I keep Oracle Spatial data in Coherence Caches?

You can store the Oracle Spatial data in Coherence caches. But creating Spatial indexes in Coherence neeeds too much effort, I guess. How do you create the Spatial geocoding package, map symbols, map styling rules and Spatial network model?

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?

I need to move 1000 photos from one library to another. How do I do that and keep the ratings and dates they were created?

I need to move 1000 photos from one library to another. How do I do that and keep the ratings and dates they were created? I tried exporting them, but it loses all info. Also, how do I move the quicktime movies from one iphoto library to another? They were exported as jpgs

Add both libraries to iPhoto Library Manager. Then select the events or albums that you want to copy from library A and drag them to library B in iPLM.

How do I keep the time and date stamp of my photo when exporting from iphoto

Hi,
I notice the time and date stamp changed when I exported the photos from iPhoto 11 to a external HDD.
When I looked at the information about the exported photos on my external HDD the time and date changed to the time and date of when I exported the photos form iPhoto instead of keeping the time and date information of when the photo was taken as it appears in iPhoto.
I thought the time and date stamp is in the meta data of the photo file and can't be changed, am I correct?
Thanks,

Kyzelios,
How can view the meta data from "finder" or do I need a 3rd party app?
"Get info" function only gives me the creation date which is the export date and time.

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:
<?xml version="1.0" encoding="UTF-8" ?>

The sytem out from the oc4j container provides this error message:

[Begginer] How to view my Oracle spatial Data ?

I'm a begginer , I know how to make and insert Spatial data but , i want to see it like map , how ?
Please tell me the software and good documentation ?

Try using MapViewer. It is downloadable from OTN:

then click on the software button to find instructions and the MapViewer software.

Interfacing Oracle spatial data with ArcView 9

Hello,
I'm trying to take my spatial data in Oracle which has SDO_GEOMETRY fields, and have it display in ArcView. I know I have to do something with SDO_GEOMETRY, but I'm not sure how. I've been reading that 3rd party tools can be used. Is this the only way, or is there something else I can do?
Thanks much,
Nora

the way i use is through arcsde. register the oracle table with sde and then you can view it in any arc software.
there is another way through direct connect. i havent used it but you can find some help on esri website.

What countries are supported by the Oracle Spatial Geocoder (10g 2)?

hi @ all,
can anybody tell me which countries are supported (especially in east-europe[turkey,georgia,...]) ?
Denmark
France
Germany
Ireland
Italy
Regards,
greq

Hi Luc,
our data supplier deliver us the geodata as shape-files, so we migrate them in 'Oracle Spatial geocoding' tables.
For some countries (west europe: germany, france,... ) a geocoding-Parser already exists, but not for all countries. We get now some new data from turkey, ukraina, ..., but we don't know if a parser for this countries exists.

Can you re-import your CD's in high quality, but keep the original track data?

Dear All
I got roughly halfway through importing my collection of about 800 CD's into iTunes 12, before realising that the default import settings applied by iTunes is not 'the best'. In fact it's not set anywhere near 'the best', it's something like 128kbps lossy format.   I wanted to import my CD's in lossless CD-quality. WAV would have been ideal. However it would appear I've missed a trick by assuming it would be full-quality unless I specified something else.
I'm not using portable devices to listen to my music, I have a Mac Mini and an endless supply of hard-drive storage space, and I'm only accessing it at home.
A large number of my discs are classical and jazz, and in many cases I've needed to amend or reorganise the metadata, so that it all complies with an overall filing and categorising system that makes sense and is useful.   I also have a large number of rock and blues CD's, but their metadata is normally correct when the discs are issued, so they usually doesn't need adjusting.   If you're wondering, yes my taste in music is eclectic.   I'm just as big a fan of Mozart as I am of Motorhead as I am of Mo Foster.   The problem is that with classical and opera it's important that the 'artist' category shows the names of the performer/soloist/conductor/orchestra, not the name of the composer! (I wish I *did* have actual recordings of JS Bach playing the Well Tempered Clavier!!).
So I'm looking at this big pile of CD's thinking, "is it worth re-importing them all again at CD-quality?", because I'd really like top-quality copies, and I only really want to have to do this once.   It *is* worth doing so long as I don't have to do all the jiggery-pokery with all the artist/composer data again, because that takes an enormous amount of time.
So the question is... will iTunes 12 let me re-import my discs at maximum quality, but at the same time let me keep the data that was painstakingly edited and stored with the previous (lesser-quality) versions?   Or is there a workaround? Maybe I could surreptitiously replace the old audio with new audio when iTunes isn't running and hope that it won't notice?
It goes without saying that I have spent quite a while trying to do this for myself before asking the forum, and so far I've drawn a blank so I'd be very grateful for any expert thoughts and opinions.
Best wishes
Nick

HI
Don't use WAV format as you will not retain metadate. You should use aiff if space is not a problem but Apple lossles format will be just as good with smaller file size.
When you reimport your CDS, you will be asked if you wish to replace existing copies. Select yes, you data changes should be retained. Be aware that when you reimport, CD track names and album title must match your existing files, otherwise they will not replace existing versions.

Point Object of the Oracle Spatial

Dear All,
This is C. T. Lin. I got some problem about point object of the Oracle geometry!
Describe:
1.I use the GeoMedia Professional to export the points to Oracle, but the oracle do not insert the geometry data into the SDO_Point, the Geomedia put the point geometry into the Ordinate_Array.
2. I also use the MapInfo Professional to export the points to oracle, then the geometry write in the SDO_Point!
3. the problem is occur! the MapInfo look like support the Point object that define the coordinate in the SDO_Point ,only!
So, Can some one tell me how to write the coordinate data from the Ordinate_array into SDO_point!

First you should create a PL/SQL function that does this convertion. Here is two version of this function, one 2D and one 3D:
CREATE OR REPLACE
Function changePoint3D ( Geo Mdsys.Sdo_geometry )
return Mdsys.Sdo_geometry AS
declare
Point mdsys.sdo_geometry ;
begin
Point := Mdsys.Sdo_geometry( 3001, 82344,
Mdsys.Sdo_point_type( geo.sdo_ordinates(1), geo.sdo_ordinates(2), geo.sdo_ordinates(2) ),
NULL, NULL );
return Point;
end;
Function changePoint2D ( Geo IN Mdsys.Sdo_geometry ) return Mdsys.Sdo_geometry AS
Point mdsys.sdo_geometry ;
begin
Point := Mdsys.Sdo_geometry( 2001, 82344,
Mdsys.Sdo_point_type( geo.sdo_ordinates(1), geo.sdo_ordinates(2), NULL ),
NULL, NULL );
return Point;
end;
When you have these functions defined it is very easy to do what you want with a simple update sentence , like this :
update table_X set Geo_Column = changePoint3D( Geo_Column );
Hope this helps you.

Update Oracle spatial data!

Hi everybody!
i'm new in Spatial, i want to update data in Oracle spatial to make a map of Asia with couty, street, state...
Could any body tell me where source to update.
Thanks so much.

I do not understand.
Do You need to update Your own tables, or You need to find reference data for Asia which You intend to import into Oracle Spatial?
If You are seeking for reference data for Asia, then You need to find it for every country. I doubt that exist for entire continent.
If You have Your own table and want to extend it with conty, street etc, You can use simple ALTER statement, like:
ALTER TABLE <table_name> ADD (
state VARCHAR2(25),
county VARCHAR(25)
);
