[HELP] EJB using Oracle Spatial

hello staff,
I'm with a doubt I'm working with EJB and JDeveloper 11g and I need a map table space that has the kind of field MDSYS.SDO_GEOMETRY, as I do to map the table by creating an EJB Bean Entities with the field JGeometry when the data type the table by MDSYS.SDO_GEOMETRY
Regards

I found the solution to the blog of our friend's Andrejus Baranovskis

How to use Oracle Spatial in this scenario

My scenario is like that:
I'm very new to Oracle Spatial
I'm building an application that will be based on asp.net.(I am
confident about .net)
As per my client requirement there are some kml file in one archive
folder.
Let me give an example:
say there is a kml file for region A.(latitude say 36 n to 40 n and
longitude is 110 w to 115 w) already in the archive folder.
Now if a new kml file(say A1.kml) that has been created by the user
and say its latitude and longitude are respectively 37n and 112w. As we clicked A.kml, google earth is opened up for the region A and as
we move our mouse cursor to more deeper more polygons are visible.
eventually polygon for A1.kml is also visible and definitely which is
inside the polygon for region A.
How can I achieve this thing by using oracle spatial 10g? ---(it's one of my senior's advice to use "oracle spatial 10g" in this scenario)
I'm not too sure whether I can able to make it clear to u about my
situation; plz xcuse me if I'm wasting ur valuable time.

Quick and easy way to learn to use Oracle Spatial?

Could anyone recommend a quick and easy way to learn to use Oracle Spatial?

Depends on your style.
Reminds me of a story a contractor to an IT department I worked in once told me.
He used to work in Silicon Valley in the '70s and told a story of a company that
hired a particular programmer who was brilliant but unstable. They used to set
up a room with a VT100 and a bottle of Tequila. The programmer would arrive
and set to work. As the Tequila emptied it was replaced. At some point over
the following days or weeks a scream would be heard from the room, followed
by a crash as the VT100 went through the window and the programmer disappeared.
They would replace the window, the VT100, the Tequila and wait till he came back
from "walkabout".
"Extreme Programming" '70s tyle!
OH&S would never allow this nowadays! That, plus Prozac means these sorts
of programmers are probably very rare!
Cheers!

Looking for some help with using Oracle stored procedures in vb2010

First off thank you to whoever lends me a hand with my problem. A little background first I am in a software development class and we are currently building our program using VB (I have no experience in this), and Oracle(currently in a Oracle class so I know how to use Oracle itself just not with VB).
I am using vb2010 express edition if that helps. Currently I have a stored procedure that takes a 4char "ID" that returns a position (ie, salesperson,manager ect). I want to use the position returned to determine what vb form is displayed (this is acting as a login as you dont want a salesperson accessing the accountants page for payroll ect).
Here is the code I have currently on the login page of my VB form
Imports Oracle.DataAccess.Client
Imports Oracle.DataAccess.Types
Public Class Login
Dim conn As New OracleConnection
Private Sub empID_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles empID.Click
End Sub
Private Sub LoginBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LoginBtn.Click
conn.ConnectionString = "User ID = Auto" & _
";Password = ********" & _
";Data Source = XE"
conn.Open()
Dim sq1 As String = "Return_Position" 'name of procedure
Dim cmd As New OracleCommand(sq1, conn)
cmd.CommandType = CommandType.StoredProcedure
cmd.Parameters.Add(New OracleParameter("I_EmpID", OracleDbType.Char, 4)).Value = Emp_ID.Text
Dim dataReader As OracleDataReader = cmd.ExecuteReader
dataReader.Read()
Dim position As New ListBox
position.Items.Add(dataReader.GetString(0)) 'were I am getting an error, I also tried using the dataReader.getstring(0) to store its value in a string but its a no go
If position.FindStringExact("MANAGER") = "MANAGER" Then
Me.Hide()
Dim CallMenu As New Menu()
CallMenu.ShowDialog()
End If
LoginBtn.Enabled = False
End Sub
I have read the oracle.net developer guide for using oracle in vb2010 and have successfully gotten through the document however they never use a stored procedure, since the teacher wants this program to user a layered architecture I cannot directly store sql queries like the document does, thus the reason I want to use stored procedures.
This is getting frustrating getting stuck with this having no background in VB, I could easily do this in c++ using file i/o even through it would be a pain in the rear....

Hello,
I am calling Oracle 11g stored procedures from VB.Net 2010. Here is a code sample (based on your code) you should be able to successfully implement in your application.
Please note that you may have to modify your stored procedure to include an OUT parameter (the employee position) if it doesn't have it yet.
Private Sub LoginBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LoginBtn.Click
Dim sProcedureName As String = "Return_Position" 'name of stored procedure
Dim ORConn as OracleConnection, sConn as String
Dim sPosition as String, sDataSource as String, sSchema as String, sPWD as String
Dim cmd As OracleCommand
'please provide below sDataSource, sSchema and sPWD in order to connect to your Oracle DB
sConn = "Data Source=" & sDataSource & ";User Id=" & sSchema & ";Password=" & sPWD & ";"
ORConn = New OracleConnection(sConn)
ORConn.Open()
cmd = New OracleCommand(sProcedureName, ORConn)
With cmd
.CommandType = Data.CommandType.StoredProcedure
'input parameter in your stored procedure is EmpId
.Parameters.Add("EmpID", OracleDbType.Varchar2).Value = Emp_ID.Text
.Parameters.Item("EmpID").Direction = ParameterDirection.Input
'output parameter in your stored procedure is Emp_Position
.Parameters.Add("Emp_Position", OracleDbType.Varchar2).Direction = ParameterDirection.Output
.Parameters.Item("Emp_Position").Size = 50 'max number of characters for employee position
Try
.ExecuteNonQuery()
Catch ex As Exception
MsgBox(ex.Message)
Exit sub
End Try
End With
sPosition = cmd.Parameters.Item("Emp_Position").Value.ToString
'close Oracle command
If Not Cmd Is Nothing Then Cmd.Dispose()
Cmd = Nothing
'close Oracle connection
If Not ORConn Is Nothing Then
If not ORConn.State = 0 Then
ORConn.Close()
End If
ORConn.Dispose()
End If
ORConn = Nothing
If UCase(sPosition) = "MANAGER" Then
Me.Hide()
Dim CallMenu As New Menu()
CallMenu.ShowDialog()
End If
LoginBtn.Enabled = False
End Sub
If you need further assistance with the code, please let me know.

Very slow queries when using oracle spatial

Hi,
I am new to oracle, please help with me the problem that I am facing.
I am storing spatial regions inside the data base. The data is in very simple in form. That is each region is a small rectangle. The boundaries of rectangle touch each other but they do not overlap. Basically I am filling the 2D space with rectangles.
I use the SDO_FILTER query to find regions inside the data base that intersect with a line. The data base contains a single table. With one column of type SDO_GEOMETRY. And the table has around 25000 tuples.
The problem is that when the result of the query is large (70% of the tuples) that means there are many regions in the cache that intersect the line, the amount of time it takes is a lot more(6 times) than if I do the same without using the R Tree.
I can do it without using the R Tree because all my objects are rectangles. I store the the left bottom and the top right corner of the rectangle in the data base. And then use a simple range query.
Is this behaviour expected? should I use an R Tree index structure, or something else. I know that when the result is very large the R Tree search will have to search many sub trees to retrieve the data points. But should the performance be worse than a sequential scan?
Or will indexes only work for cases where the selectivity of the query is high?
Please reply I need help,
Thank you,
Nishant

Hi,
I am using the version of spatial that we get with Oracle9i Release 2 (9.2.0.1) or it could be
Oracle 9i release 2 (9.2.0.2).
I don't know how to check that.
Here I provide the create script, create index statement and a few sample data items that I insert into the data base.
Create Script:
create table out5d(
ID                          NUMBER(9),
PID NUMBER(9),
X                          NUMBER,
Y NUMBER,
L NUMBER,
PL NUMBER,
shape                          MDSYS.SDO_GEOMETRY,
HEIGHT                         NUMBER,
N                          NUMBER(9),
d0 NUMBER,
d1 NUMBER,
d2 NUMBER,
d3 NUMBER,
d4                         NUMBER,
D0_MAX NUMBER,
D1_MAX NUMBER,
D2_MAX NUMBER,
D3_MAX NUMBER,
D4_MAX NUMBER,
D0_MIN NUMBER,
D1_MIN NUMBER,
D2_MIN NUMBER,
D3_MIN NUMBER,
D4_MIN NUMBER);
alter table out5d
add constraint keyConstraint
primary key (ID);
Create Index:
INSERT INTO USER_SDO_GEOM_METADATA VALUES ('out5d' , 'shape' , MDSYS.SDO_DIM_ARRAY( MDSYS.SDO_DIM_ELEMENT('X', 0, 1, 0.0000001), MDSYS.SDO_DIM_ELEMENT('Y', 0, 1, 0.0000001) ), NULL);
CREATE INDEX out5d_rtree ON out5d(shape) INDEXTYPE IS MDSYS.SPATIAL_INDEX;
I changed the fan out to 50. Because I read in the spatial user guide that in case you are expecting a big output result you should increase the fan out to 50 or 60.
Also here is a sample data items that I inserted into the tables.

Path direction in Oracle spatial network data model

Hi all,
can any one help me how to implement path direction using oracle network data Model?
We are using Oracle Spatial database. there is one feature called network constraint in Network data Model. but how to implement path direction of my Network ? Please help me any one

The path direction in a Spatial network is enabled at creation time when calling the create network procedure such as SDO_NET.CREATE_LOGICAL_NETWORK. If you describe the Create procedure you're using you should see a IS_DIRECTED argument, which when set to TRUE will enable path direction. Then just ensure that your links are created in the right direction -specifying correct orientation for start node and end node.
Cheers,
Stuart.

Oracle Spatial explained!?

Can anyone tell me in layman terms about Oracle Spatial please? I know it's a feature to help GIS solutions but can someone define this for a novice such as myself?
Thanks, Ian Bennett

I have not actually used Oracle Spatial, but I do have some experience with GIS solutions. What I do know is that Oracle Spatial provides capabilities designed to more easily deal with geometric data types, such as shapes, lines and points. Functionality which would be difficult to achieve with standard data types is optimized (for example, the ability to query all customers within a 10 mile radius of a known location). Another common component of GIS systems is geocoding (converting an address to a geographic coordinate like latitude / longitude).

I suggest reading the Oracle Spatial User's Guide

SDO_NN with Oracle Spatial

Hello,
although the description of my problem is a bit long, I hope you could help me.
I would like to compute the nearest neighbor of a point being located on the surface of the unit sphere.
For that query, I would like to take advantage of the features provided by Oracle Spatial (10g).
Table spatial_test contains the columns point_name, x, y, z, ra, dec where:
point_name is the primary key
x, y, z are the coordinates of the points on the unit sphere (so x^2+y^2+z^2=1)
ra, dec are the the concerning spherical coordinates where the following conditions hold: x=cos(dec)*cos(ra) , y=cos(dec)*sin(ra), z=sin(dec).
For computing the nearest neighbor of a point with point_name='point1' the query without using Oracle Spatial is:
select * from(
select
acos(t1.x*t2.x+t1.y*t2.y+t1.z*t2.z) as distance, t1.*
from spatial_test t1,
spatial_test t2
where t2.point_name='point1'
and t1.name != t2.name
order by dist
where rownum<2;
For taking advantage of Oracle Spatial, I have to prepare my data doing the following five steps:
1. add a column to of type SDO_GEOMETRY to table spatial_test
2. insert values to that table
3. update table user_sdo_geom_metadata
4. create the spatial index
5. execute the following query on the amended table spatial_test:
SELECT t1.point_name name1, t2.point_name name2 FROM spatial_test t1, spatial_test t2
WHERE SDO_NN(t2.geom, t1.geom, 'sdo_num_res=2') = 'TRUE'
and t1.point_name = 'point1'
and t1.point_NAME != t2.point_name
As mentioned in the User Guide for Oracle Spatial, only two dimensional objects are supported.
So, if I insert tuples in the following form to my table:
insert into spatial_test (point_name, x, y, z, geom) values (..., ..., ..., ...,
SDO_GEOMETRY(3001,
NULL, --SDO_SRID is null, so no coordinate system is associated with the geometry
SDO_POINT_TYPE(x_value, y_value, z_value),
NULL,
NULL));
I won't get the correct results. I assume that the z_value is just ignored. Am I right with that assumption?
For using Oracle Spatial, I have to use the equivalent just using two dimensions. Since ra, dec is another representation for x, y, z, I tried to do the same, just using ra and dec. But here, my results also differ from the ones computed with my own computation of the nearest neighbor.
Here an minimal example which shows my problem:
CREATE TABLE spatial_test(
point_name varchar(20) PRIMARY KEY,
x float,
y float,
z float,
ra float,
dec float,
geom SDO_GEOMETRY);
-- INSERT POINTS --
insert into spatial_test(point_name, x, y, z, ra, dec, geom) values ('point1', -0.00472924, 0.110927216, 0.99381728, 92.44125, 83.62542,
SDO_GEOMETRY(2001, -- 2 dimensions, last dimension is the measure, geometry type 01 = point
NULL, --SDO_SRID is null, so no coordinate system is associated with the geometry
SDO_POINT_TYPE(92.44125, 83.62542, null),
NULL,
NULL));
insert into spatial_test(point_name, x, y, z, ra, dec, geom) values ('point2', -0.00239923, 0.112814014, 0.993613226, 91.21833, 83.52097,
SDO_GEOMETRY(2001, -- 2 dimensions, last dimension is the measure, geometry type 01 = point
NULL, --SDO_SRID is null, so no coordinate system is associated with the geometry
SDO_POINT_TYPE(91.21833, 83.52097, null),
NULL,
NULL));
insert into spatial_test(point_name, x, y, z, ra, dec, geom) values ('point3', -0.00701052, 0.122780703, 0.992409065, 93.26792, 82.93584,
SDO_GEOMETRY(2001, -- 2 dimensions, last dimension is the measure, geometry type 01 = point
NULL, --SDO_SRID is null, so no coordinate system is associated with the geometry
SDO_POINT_TYPE(93.26792, 82.93584, null),
NULL,
NULL));
-- UPDATA user_sdo_geom_metadata --
INSERT INTO user_sdo_geom_metadata
(TABLE_NAME,
COLUMN_NAME,
DIMINFO,
SRID)
VALUES (
'spatial_test',
'geom',
MDSYS.SDO_DIM_ARRAY(
MDSYS.SDO_DIM_ELEMENT('ra', 0.0, 360.0, 0.0000000000001),
MDSYS.SDO_DIM_ELEMENT('dec', -90.0, 90.0, 0.0000000000001)
NULL -- no specific coordinate system should be associated with the geometries.
-- CREATE THE SPATIAL INDEX --
CREATE INDEX spatial_test_idx
ON spatial_test(geom)
INDEXTYPE IS MDSYS.SPATIAL_INDEX;
Now I could execute the following queries which should both compute the nearest neighbor of 'point1'.
This is the statement computing the nearest neighbor without Oracle Spatial:
select * from(
select
acos(t1.x*t2.x+t1.y*t2.y+t1.z*t2.z) as distance, t2.point_name p1, t1.point_name p2
from spatial_test t1,
spatial_test t2
where t2.point_name='point1'
and t1.point_name != t2.point_name
order by distance
where rownum<2;
RESULT:
DISTANCE P1 P2
,003005107 point1 point2
With the following statement, I compute the nearest neighbor of 'point1' using Oracle Spatial:
SELECT t1.point_name name1, t2.point_name name2 FROM spatial_test t1, spatial_test t2
WHERE SDO_NN(t2.geom, t1.geom, 'sdo_num_res=2') = 'TRUE'
and t1.point_name = 'point1'
and t1.point_NAME != t2.point_name;
RESULT:
NAME1 NAME2
point1 point3
As you see, unfortunately, the two results differ.
Could you please tell me, what I understood wrong in using Oracle Spatial?
In addition, what kind of coordinate system is assumed if it isn't specified in my SDO_GEOMETRY? Which kind of distance is computed using sdo_nn (euclidean distance, ...)?
Would be glad, if you could tell how to reach the same results for my nearest neighbors using Oracle Spatial.
Regards,
Ina

I would like to compute the nearest neighbor of a
point being located on the surface of the unit
sphere.That would be a spherical 3D computation. Currently, OS does not work well with 3D such as spheres, sorry. I know R2 was supposed to improve on this for cubes and pyramids, but to be honest; I havent had time to go back and test the simple cube operations. With 10gR1, for most of the operators and functions 2,2,3 and 2,2,5 are same point. I know this is something that is being worked on, possibly Dan can comment further.
See for more info:
Re: 3D Polygon
For now, if you have your own routines, Id use them as a package instead. If you need help there, let us know and well try to point you in the right direction or help you to translate the code to PL/SQL.

Reengineering Desktop Thick Workgroups into Web
Rich Enterprise Clients
Bryan Hall, Spatial Architect, L-3 Communications
Jeff Walawender, Senior Software Engineer, L-3 Communications
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.

Oracle Open World in SanFrancisco and Oracle Spatial

Hi,
This week is Oracle Open World in San Francisco, and while usually we try to keep this message board strictly technical, I wanted to mention that there are some interesting things happening here.
There are a few sessions Wednesday in Room 2016 starting at 3:00 pm:
Data Management on a Budget with Oracle 10g: Exploring Strategies and Tactics with the U.S. Geological Survey
by Nate Booth and Harold House, USGS
Oracle Database 10g Spatial Performance and Manageability Best Practices and German Rail Case Study
by Dan Abugov (me) and Andreas Hoefler, Fichtner Consulting & IT AG
I'm excited to be talking about Partitioning Best Practices, and we'll be posting the white paper here on OTN.
Finally, please come and see us at booth E28 in the Oracle DemoGrounds (we have Locator/Spatial, MapViewer, and Workspace Manager here in the pod). If you are the FIRST person to mention reading this posting on OTN when you visit the booth, we'll be happy to give you a copy of "Pro Oracle Spatial", the first book devoted to developing applications using Oracle Spatial. The book was written by Ravi Kothuri, Albert Godfrind (two Oracle Spatial Developers) and Euro Beinat of Geodan NL. One of the authors (Albert Godfrind) is here, and if you ask I'd bet he'd autograph it for you!
We also have a very limited supply of the book we'll be giving out over the course of the conference.
Of course, everyone who stops by will get the Oracle Spatial mini CD which includes viewlets, white papers, and more.
The book is also available here:
http://www.amazon.com/exec/obidos/tg/detail/-/1590593839/qid=1102358585/sr=1-1/ref=sr_1_1/002-9450919-8639226?v=glance&s=books

Hello,
Take a look at this page, http://www.oracle.com/technology/events/oracle-openworld-2007/index.html
There are links here to the whole OOW (social network,twitter,blog/flicker)osphere I think the new buzzword being "Social Graph" that covers all that.
But anyway there are tons of ways for people to sign up and track the sessions and see who's going to go where, etc.

Carl

Oracle Spatial on RAC

Hi,
We have an application where we use Oracle Spatial (SDO_GEOMETRY) and we use Eclipselink as the JPA provider. When using this on RAC with MutliDatasource with algorithm as "LoadBalancing" we are seeing the following exception when storing entities
An error has occured flushing the user transaction.

The same works in standalone DB or if the MultiDataSource algorithm is failover. Similarly when a RAC node goes down, the same problem exists even with Failover
I searched in Oracle forums and found the following link which could be related
https://community.oracle.com/message/1147983#1147983
By looking at the above pattern, I think if the JGeometry class is passed different connections (one of each node) it fails. Is there a way to clear the descriptors in Eclipselink safely?
Is Spatial designed to work with RAC ?
Any pointers on how to solve this is highly appreciated.
Thanks,
Rama

Hello
You should try to split the upgrade into two tasks - upgrade and migration. Upgrade to 11.2.0.3 on the Windows server first and then migrate to the Linux RAC.
Spatial will be upgraded as part of the database upgrade, you may need to reindex as per
http://docs.oracle.com/cd/E11882_01/appdev.112/e11830/sdo_migrat.htm
There are many ways to migrate from Windows to Linux, you could use RMAN as it is possible to restore Windows backups on Linux and vice versa.

Nice to have a EXPERT in this FORUM...!!
Hi Dan, if you look at my reply I mentioned that I had loaded loc_updates.sql
From my previous reply:
execute loc_updates.sql which doenot update any of the rows since if you look at the syntax in loc_updates.sql file it shows update the table customers whose customer_id=344.
Where is this customer_id=344 coming from?
Also the datatype is a number.
Dan, were you able to get the results as desired?
or may be I am missing something...
Thanks and Regards,
Nandakishore.
