Using Java with Oracle Spatial

I am using the JDBC (Java classes dowloaded from
technet.oracle.com - (sdoapi.zip)) together with Oracle Spatial
8.1.6. I am writing a collection of Linestrings into Oracle
Spatial using the supplied java classes(sdoapi.zip). I use the
function createGeometryCollection(myCollection)to write the
Linestring collection to Oracle Spatial and they are written to
the database without error. However, when I try to read the
object back I get the following error:
Exception in thread "main"
oracle.sdoapi.geom.InvalidGeometryException
at oracle.sdoapi.adapter.AdapterSDO.importGeometry
(AdapterSDO.java:101)
at
MapInfoToOracleSpatial.MapInfoToOracleSpatial.main
(MapInfoToOracleSpatial.java:211)
I do not have a listing of this code so can you please tell me
what the error is (line of code) at line 211. Also, when I use
the Oracle Spatial Index Advisor to view the spatial data, it
only displays a quarter of the data. When I use MapInfo to view
it's equivalent TAB (Table) file it views correctly all the
data.
I can't understand why this is happening because the writing to
oracle and creation of each individual linestring does not
throw an error. It is only when I try to read back larger
objects from the database (2500 points) that it gives an error.
Is there a limitation on the size one can create linestrings?
Thanks

Using Toplink with Oracle Spatial (missing right parenthesis error)

Hi,
I always get the following error when I try to create spatial query with toplink.
Internal Exception: java.sql.SQLException: ORA-00907: missing right parenthesis
Any idea ? Also, there is no trace of my point in the generated sql....
Here is the generated query:
SELECT ID, [...]
FROM QUEBEC_CITY
WHERE (MDSYS.SDO_NN(GEOMETRY, JGeometry (gtype=1, dim=2, rid=8307, NULL) = 'TRUE')
ORDER BY ID ASC
Here is my code... :
double[] coord = new double[]{-71.25163d, 46.8527d};
JGeometry point = JGeometry.createPoint(coord, 2, 8307);
SpatialOperator nearestNeighbor = SpatialOperator.nearestNeighbor(session);
ReadAllQuery query = new ReadAllQuery(UrbanEdgeDescriptor.class);
ExpressionBuilder eb = query.getExpressionBuilder();
Expression geom = eb.get("geometry");
query.setSelectionCriteria(nearestNeighbor.buildExpression(geom, point));
query.addAscendingOrdering("id");
List<UrbanEdgeDescriptor> results = (List)db.getSession().executeQuery(query);
System.out.println(results!=null);

The problem is the toString() on JGeometry. It does not print out a complete description the database can use inline. It produces:
JGeometry (gtype=1, dim=2, rid=8307
To get JGeometry types to work in your queries the easiest solution is to use parameter binding so the literal representation is not used.

Regarding working with oracle spatial database connections

sir/madem,
i am an engg student, my final year project on inserting data into oracle spatial database through java /jsp , i am working with oracle spatial database 10g/11g,
i want know how to insert/retrive/ manuplute the spatial data into oracle spatial databse for 10g/11g, through java programing,

For database access from Java, you will use JDBC.
For the specifics of the oracle spatial database, you'll have to check the documentation/forum of Oracle.

Poor performance with Oracle Spatial when spatial query invoked remotely

Is anyone aware of any problems with Oracle Spatial (10.2.0.4 with patches 6989483 and 7003151 on Red Hat Linux 4) which might explain why a spatial query (SDO_WITHIN_DISTANCE) would perform 20 times worse when it was invoked remotely from another computer (using SQLplus) vs. invoking the very same query from the database server itself (also using SQLplus)?
Does Oracle Spatial have any known problems with servers which use SAN disk storage? That is the primary difference between a server in which I see this poor performance and another server where the performance is fine.
Thank you in advance for any thoughts you might share.

OK, that's clearer.
Are you sure it is the SQL inside the procedure that is causing the problem? To check, try extracting the SQL from inside the procedure and run it in SQLPLUS with
set autotrace on
set timing on
SELECT ....If the plans and performance are the same then it may be something inside the procedure itself.
Have you profiled the procedure? Here is an example of how to do it:
Prompt Firstly, create PL/SQL profiler table
@$ORACLE_HOME/rdbms/admin/proftab.sql
Prompt Secondly, use the profiler to gather stats on execution characteristics
DECLARE
l_run_num PLS_INTEGER := 1;
l_max_num PLS_INTEGER := 1;

BEGIN
dbms_output.put_line('Start Profiler Result = ' || DBMS_PROFILER.START_PROFILER(run_comment => 'PARALLEL PROFILE')); -- The comment name can be anything: here it is related to the Parallel procedure I am testing.
v_geom := Parallel(v_geom,10,0.05,1); -- Put your procedure call here
dbms_output.put_line('Stop Profiler Result = ' || DBMS_PROFILER.STOP_PROFILER );
END;
SHOW ERRORS

How to use Java with PL/SQL commands to send an email with attachment

Apologizes in advance if this is the wrong place to ask the question.
I need to use Java with PL/SQL commands to send an email with attachment. My java application runs from the command line and does some magic to gather info from an Oracle 11g db. If the DB has sendmail configured, I'd like to send the results of the data gathering as an attachment to the email addresses. I'm not sure how to do this. I've been reading up on on PL/SQL can send email with UTL_SMTP - with attachments. I'm just not sure how to translate that into being triggered by my Java application. Any suggestions or pointers on what I should read would be appreciated.
Background - I've been programming in Java for 10+ years, but this is my first time using databases. I also have been on these forums for a long time, but lost my profile when it was switched to Oracle.
Thanks for all help.

user13726880 wrote:
The original requirements were put together and given to me, an Oracle newbie. They expected the Java app to use something intrinsic to Oracle and Unix sendmail. To solve my problem, I use a JDBC connection to run some SQL commands. I take that data, format it and send the results by email to the user. By default the requirement is to send it as an HTML attachment using Unix 'sendmail'. So I do that using Runtime exec. I have also added JavaMail functionality as an alternative to sendmail. It works great and as expected.Sounds like a reasonable solution.
Note however that PL/SQL itself can send email. And PL/SQL can call unix sendmail too.
However myself I would have done it in java with JavaMail.

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.

Markus,
Sorry for my late reply it had been awhile since I was here at SDN
I did it manually in the 'old' way and at that time it did work.
Kulvir,
I did get it from SAPnet but when I downloaded it it contained the proper file.But I did had the same with an add-on for the business connector which only contained an empty file.
Thanks for your answers and again sorry for my late reply back to you all

Hi,
Oracle JVM in 11gR2 (the latest release) supports Java 1.5 only. So no, you won't be able to load classes compiled with target class level 1.6 into DB. But you surely may explicitly set target class level of 1.5 in javac and then load compiled classes. Or you may not use 1.6 features in your code and then CREATE JAVA SOURCE from it.

Problem while using XML with Oracle

I have a problem using XML with oracle applications
The process I am following
1. Making a XML string.
2. Parsing it to get a document
3. Free the parser using xmlparser.freeparser
4. Traversing through nodes .
5. Freeing the document.
The whole Process is executed in batch mode.
The problem occurs after executing the procedure for 5000 records and I get the error
ORA-04031: unable to allocate 4176 bytes of shared memory ("shared pool","unknown object","sga
heap","library cache")
Can you please help me out to overcome this problem
It's urgent
I have
Oracle version 8.1.7.0.0
XML version 1.2
OS Windows NT
To resolve the problem I have increase shared memory size and java initialization parameters ,which seems OK
Looking forward for your answer.

Hello, Reena
Your process flow seems to be correct in term of getting/freeing memory.
Following error
The problem occurs after executing the procedure for 5000 records and I get the error
ORA-04031: unable to allocate 4176 bytes of shared memory ("shared pool","unknown object","sga
heap","library cache")may be caused by memory leaks in xdk or memory fragmentation(due to get/free memory cycle)
To find out if this is an memory leak issue you could try to monitor V$SGASTAT from one session while running your batch process in another session.
To prevent (or lower its impact) fragmentation issues try to PIN objects, and adjust java_pool_size and shared_pool_reserved_size.
Anyway, counsult your Oracle DBA.
Oracle version 8.1.7.0.0I think, you should apply database patch first of all. The latest one (8.1.7.4.x) could be accured from Metalink.

Server Hardware for Oracle Database 11g Release 2 with Oracle Spatial

Hi ,
We're to set up an Oracle Database 11g Release 2 Enterprise with Oracle Spatial.
Can you provide me the possible Server Hardware CPU / Memory specs , number of CPUs,type of OS and teh Model, for Spatial which a million users hits the database via a webservice?
The vendor suggested us SDD instead of HDD, any performance hike on this?
Budget seems to okay but I think Exadata will be too dear.
Your insights is much appreciated.Anything relating to setting up a server with spatial is greatly appreciated.
P/S: Been a programmer and don't knwo much about server hardware specs.

It depends.
Seriously - before anyone can offer anything but generalities here you need to really define exactly what you expect the database to deliver.
In general however, I will throw out these questions and ideas...
For instance - you say a million users "hit" the database (via a web service). Is that WFS, WMS, KML or ???
Over - how long? A year? A month? A minute? A million hits over a year spread out evenly is only about 2 per minute.
And what is a hit? A single random record? Or about 10,000 records in the same spatial area... or? And for each record - are you returning simple point data - or hugely complex polygons with thousands of vertexes each?
How does this software work? Is it custom - or is it well known? Does it really query the database for every map (I assume it is a map service) feature - or does it read an area once and cache it in the middle tier? Or does it do something really smart and use cached tiles for static data - overlayed with vectors for dynamic data?
And although you say Oracle Spatial - are you really using Spatial - or just Locator functions (less processing in general)? And if spatial - are you doing raster in the db - or 3D analysis - or other special functionality?
SSD vs. HDD. - If you can buy a server with more RAM than the data set size (pretty easy these days) - and you do mostly reads (almost always the case for a map app) - buy a small cheap array of RAID'd HDD's - internal to the server is fine. Once the data is read into RAM - the HDD's do basically nothing.
Server CPU and memory. Amount - see above. CPU Speed (use performance benchmarks - not GHz numbers) AND memory speed (often overlooked) - buy as fast as possible. Why? You pay for licenses by the core (2 cores per license for x64). And HW is MUCH MUCH MUCH cheaper than Oracle licenses. Plan to upgrade HW every year if necessary to avoid buying more licenses (sounds crazy - but it is much cheaper).
This may seem like a lot - but these questions are just the tip of the iceberg. I have been in charge of spec'ing, building, and programming spatial systems now for about 20 years, so I have a pretty good idea of how to do enterprise scale computing on a Ramon-noodle budget.
Smart clean software is your friend - don't ask the HW to do anything unless absolutely necessary (cache results and reuse as much as possible), and you can get crazy performance from minimal hardware.

Thanks you in advance for your answers.Looking at the 8.1.7 doc set (the oldest available on tahiti) I get no hits when searching for 'dict_from_online_catalog'. Searching the 9.2 doc set turns up a reference. Looks like you are trying to use an option that isn't available in your version of Oracle.

Using Tuxedo with Oracle Real Application Clusters (RAC)

Hi all ,
Our present Producation environment is Tuxedo8.0 with Oracle 9i as database .
We are planning to implement oracle RAC .
Can any one tell us , with the current tuxedo version which is 8.0 ,can we for RAC Or we need to upgrade Tuxedo to 9.1 for RAC Implementation?
If anyone has Implemented Tuxedo and Oracle with RAC successfully
Pls share your experience.
Thanks In Adavance
Nadeer .

Subbu,
As I mentioned earlier in this thread, support for Oracle RAC has been
implemented in Tuxedo 9.1 and in the Tuxedo 8.1 and Tuxedo 9.0 rolling patch
streams. There are no plans to backport this feature to Tuxedo 8.0. If you
plan to use RAC transactionally and if it is possible for multiple services
that could be located on different RAC instances to be accessed in a single
transaction (which will be true for most applications), then you should
upgrade to a version of Tuxedo with support for Oracle RAC. The
documentation at http://e-docs.bea.com/tuxedo/tux91/ads/adorac.htm#248431
gives an overview of RAC support in Tuxedo.

Hello Nadeer, Hello Ed,
Has the implementation of Tuxedo8.0 with Oracle RAC was completed
successfully ?.
If it is done , I have few doubts. Could you please help me ?.
1) I hope your Tuxedo middleware connects to the oracle Database using
Oracle XA resource manager and the TMS server built using buildtms with
oracle as RM .As per the mail from Ed, migration of Tuxedo9.1 should be done
before moving to Oracle RAC.
Also from BEA documentation, Oracle RAC support was given as new feature in
Tuxedo9.1.
Our Application uses Oracle RM to connect to Oracle DB[ Oracle 10g] from
Tuxedo8.0. So do we need to upgrade to Tuxedo9.1. for using Oracle RAC ?.
Thanks for your help
