Oracle10g Spatial - Some information

Hi,
Some of the talks at Oracle World this week will discuss publicly for the first time some of the new features in Spatial for Oracle10g. There has been some interest expressed in this forum in finding out what to expect, so some information has been put together specifically to post here.
A brief list of major features include:
Topology Data Model - The ability to store and maintain spatial data in a topologically consistent way using nodes, edges, and faces. The topology model is a persistent (stored) model. Java and PL/SQL APIs are provided for applications/users who want to update topology data. The ability to select spatial features from the topological primitives is supported, as is the ability to store spatial features in a separate geometry column.
Network Data Model - The ability to store and maintain connectivity (graph) information in the database. The network data model includes a routing engine, and it can be integrated with spatial data, linear referenced spatial data, or topology data. Cost information can be stored and accounted for when doing network analysis.
GeoRaster - The ability to store, index, and retrieve Raster data (image, grid, raster, you name it) using the Oracle 10g database. Oracle Spatial GeoRaster includes an xml metadata schema for GeoRaster metadata. GeoRaster supports georeferenced data so you can dynamically determine which pixels/cells to fetch from an image based on a set of Earth coordinates and determine Earth coordinates based on pieces of an image. It also includes the ability to publish GeoRaster data as GIFF or JPEG images.
GeoCoding - New function to generate long/lat from Address data.
Spatial data mining features for use in demographics, epidemiology, insurance, business analysis, etc.
New, supported Java API (ships with Spatial). Includes in-memory R-tree indexing.
In the Application server associated with 10g, a faster and improved version of MapViewer.
A short (incomplete) list of other new features include:
Transportable tablespace support for tables with Spatial indexes.
Generate the location of a point given a start point and bearing.
Generate GML (geography markup language) from spatial data.
SDO_JOIN feature to optimally combine two layers based on spatial interactions.
Default for SDO_RELATE and SDO_FILTER is now querytype=window, which no longer needs to be specified.
New operators for specific interactions, such as SDO_INSIDE and SDO_ANYINTERACT.
New function to validate WKTEXT of user-defined coordinate systems.
MBR type is now supported for geodetic data (internally densifies every degree of latitude).
LRS enhancements to include signed offset for some functions.
New function to estimate the R-tree index size before it is created.
Interior buffers (negative buffer distance).
...and many others.
Thanks for using spatial, and hopefully the new features will help with current development as well as give ideas for future work using spatial.

I got some info at https://www.oracleworld2003.com/published/40125/40125_Lopez.doc and at
https://www.oracleworld2003.com/published/40125/40125_Lopez_v3.ppt
However, I would like to know some details about nw functions, model etc.
Thanks
Syed

Hard drive error: Some information was unavailable during an internal lookup

I tried upgrading my hard drive on my 13" MacBook Pro (mid-2010) to a solid state drive. When I did, I encountered a problem where I could not boot from my internal drive.
It boots fine from the external drive that I used to clone my old HHD.
When I run repair disk in disk utility I get an error:
Problems were encountered during repair of the partition map
Error: Some information was unavailable during an internal lookup.
Running repair disk on the external drive returns no errors.
My first thought was I have a bad SATA cable. After replacing the SATA cable, I am still having the problem.
Anyone have any ideas on what could be the problem? SATA Connector on the motherboard failed?
Thanks in advance.

I formatted it a Mac OS Extended (Journaled) using the Erase function in Disk Utility then copied the contents of my HD using Restore in Disk Utility. It seemed to copy all of the contents correctly. It boots from the external drive.
The problem starts when I put it in the computer and try to boot internally. It will not boot. Also, my old HD will also not boot internally now either.

Hi everyone i'm trying to access a web page using midlet to retrieve some informations in text format, the web page is [http://daviddurand.info/D228/?villes|http://daviddurand.info/D228/?villes] for my project.

You need to connect to iTunes and restore.

You may need to put the device into recovery mode, this is covered in the link on this page.
Did you back up the device?

Aint you quick to jump to conslusions? So becasue one thing isn't working of the hundreds of things I donwloaded doesnt work, my drivers are broken?
Ok then, let me download some other things to make sure
Minecraft: it worked ✓

Flash: it worked✓
Synfig was made in 2006, so it's not unlikely that it might not work for some people. By 'some people', I mean me. I was just asking if it was something on my side, but if that's all you got, I think it's highly unlikely that it's my fault. I don't even want it anymore, I got Flash Professional. I was just wondering. I could have sworn you used to write more detailed answers before jumping striaght to conclusions. 'Did this happen to you on anything else?' or maybe even 'Why don't you complain to them?' would have been fine.

Good afternoon, I would like some information I have an ipod nano 6th generation and has the same one-year warranty is only 2 months of use, and it fell down and broke the glass of the display, I called technical assistance in Brazil and informed me that Brazil has no repair services for Apple, which was the basis of its price change in the exchange is not worth half the value of the product.
I wonder how I do to change this device without the expense of 50% for the same product is in warranty?
Thanks in advance.

yes agree, plus a multinational seeing a product and has no technical assistance to do the maintenance then it's no use I buy a new product if it is damaged I will always be because it has no prejudice in this maintenance.
sorry but even more products coming from China to Brazil in technical assistance.

I Need To Know Some Information About Installing Windows On A Macbook Pro 13

Hello !
Actually Playing My Favourite Games Is A Problem Because I Can't Find DVD Games (Mac Version) For My Macbook Pro So I Found Out That You Can Install Windows 7 Software On A Mac But I Wanted To Know Some Information Like :
- I Know That I Can Install It Using Boot Camp But I'll Need A Windows 7 DVD So Is There Some Specialized Version For Mac ? Or I Just Need A Normal Windows 7 DVD For PC ?
- If I Installed Windows 7, Will I Lose The Mac OS X Lion ? Or I Can Have Both Softwares Together At The Same Time ?
- If I Installed Windows 7, Will It Have The Same Specifications Of Macbook Pro 13 ? (Ex: 2.4 GHz Processor)
- If I Installed Windows 7 And I Already Had Mac OS X Lion, Will The Macbook Lag Or It Will Work Properly ?
- If There's Any More Info That You Know About Installing Windows 7 On A Macbook Pro 13, Please Provide Me With It, Thanks!

This really is a forum about the MacBook Pro hardware. The best place to ask your questions would be the Windows/BootCamp forum. Your MacBook Pro 13 has one weakness that's going to make gaming a bad experience. It has an integrated Intel HD graphics processor, whereas the higher end MacBook Pro's have discrete ATI graphics processors. But the forum will help you out.

From reading Vista forums support for SSD is one of the things Vista SP2 and Windows 7 hope (need) to improve upon. I was in a similar discussion once befoe on SSDs:

http://www.google.com/search?hl=en&rls=com.microsoft%3Aen-US&q=IntelSSDVista
I don't think it is EFI issue, but with XP and drivers, lack, and wonder if you can try with Vista?

That won't solve performance issues, but should work.
http://www.reghardware.co.uk/2008/07/22/sandiskssd_vistabeef/
"My guess is that [Samsung and Microsoft] are maybe working on the OS recognizing an SSD with a 4K-byte sector size instead of a hard disk drive with a 512-byte sector size," Wong said.
Sun is already working with Samsung to bulk up SSD support on the ZFS (Zettabyte File System), which is included in the Solaris OS, and will also be supported in Apple's upcoming Mac OS X 10.6, codenamed Snow Leopard. Sun is adding capabilities to boost the durability and performance of SSDs on ZFS-based operating systems. For example, Sun may add defragmentation capabilities for SSDs, which organizes data in a particular order to enable quicker data access.
SSDs were not considered ideal for defragmentation because of limited read-and-write capabilities, Wong said. However, Samsung and Sun in July jointly announced an 8G-byte SSD that bumped up durability from 100,000 read-and-write cycles to 500,000. That brings defragmentation in SSDs closer to reality, which could improve its caching and provide quicker access to data. Sun plans to put SSDs into storage products later this year.

Some information about http time out

hi 2 all,
I want some information about http time out,like what all different transactions are used.

Hi,
Could you be more specific? Here is a blog about timeouts:

I recently purchased some information to be downloaded to one of my apps I never received the download and I was charged multiple times I reported the problem And it's been about a week my question is how long does it take to credit my account back. It's my money and I want it now.

It can take a while for your money to show up in your bank, but a week is a bit over the top. Try contacting iTunes Store Support to make sure the refund was issued.

Create a new header+item after sync the item some informations are deleted

Hi All,
I have a DO with a backend adapter and 3 bapi wrapper (GetList, GetDetail, Create).
When I create a new instance (header+item) on client side the data are correct in the database. After a sync the instance is also on the client and the Backend but he lost some informations in the item.
For example i create e_top object (header) and t_vehicle object (item) the i added the item to the header an wirte it in the database. In the datebase both tables for header and item are correct filled.
Application Code:----
public void SaveVehicle( java.lang.String Manufacturer, int Driver, java.lang.String Licence_Number, java.lang.String Type ) {
       VEHICLE_E_TOP e_top = model.createVEHICLE_E_TOP();
       e_top.setLICENCE_NUMBER(Licence_Number);
       wdContext.nodeVEHICLE_E_TOP().bind(Collections.singleton(e_top));
       wdContext.nodeVEHICLE_E_TOP().setLeadSelection(0);
       model.addToVEHICLE_E_TOPs(e_top);
       VEHICLE_T_VEHICLES t_vehicle = e_top.createNewT_VEHICLESs();
       t_vehicle.setDRIVER_ID(Driver);
       t_vehicle.setLICENCE_NUMBER(e_top.getLICENCE_NUMBER());
       t_vehicle.setMANUFACTURER(Manufacturer);
       t_vehicle.setTYPE(Type);
       wdContext.nodeVEHICLE_E_TOP().currentVEHICLE_E_TOPElement().model();
       e_top.addToT_VEHICLESs(t_vehicle);
       wdContext.nodeVEHICLE_T_VEHICLES().bind(Collections.singleton(t_vehicle));
       wdContext.nodeVEHICLE_T_VEHICLES().setLeadSelection(0);
       model.commit();
Now when I snyc with the middleware the object is still on the client (1 row in the e_top table and 1 row in the item table) but in the row of the item table all data until the header key(Licence_Number) is deleted. In the Backend there is a new objekt with only the header imformations.
Best Regards,
Dirk

Hi,
there was another post today n a similar issue. I still do not think it is a standard issue - so lets check first if your implementation is correct.
You should have a look on the CREATE BADI in the backend and on the mapping in the DOE. I expect the CREATE handler does not get all informations form the client, cause you missed to do the propper mapping in the DOE on the middleware. Check this first. If you see the data on the client, the client side should be fine. Check the DOE and its mapping and the BADI implementation on the backend.
Hope it helps!
Regards,
Oliver
