Can not deploy Oracle Spatial Routing Engine on Oracle Weblogic

I posted my question with Oracle Support, however they directed me to the oracle forums. I am hoping this problem can be resolved here. In any event I am getting the following stack trace (shown below). I am using Spatial Version 11.2.0.1.0, Map Viewer 11.1.1.5.1, and WebLogic 10.3.5.0, and data-set provided by Pro Oracle Spatial for Oracle Database 11g - Apress boos. I have successful in deploying Map Viewer, Geocoder Server, but not the Routing Server.
Below is the stack trace:

Loading shapefiles into Oracle Spatial

Fellow Oracle Spatiallers!
Currently we edit Oracle Spatial data by checking data out into a shapefile,
making our changes off-line, and reloading the shapefile back into Oracle.
Instead of using the Oracle Spatial supplied tool, we decided to purchase
a utility called the "Spatial Loader" from a company called Geometry Pty Ltd
(http://www.geometryit.com). There are a number of reasons why we decided to
go that way which might become evident from the command line parameters of
this utility:
Usage: Shp2Spt [Arguments] [Options]
OR
Usage: Java com.geometryit.spatialloader.oracle.AdvancedJavaSpatialTranslator [Arguments] [Options]
[Arguments] must specify these values:
-o create
type of operation to perform
create creates a new table, must not exist already
recreate creates a new table, may exist already
init drops existing table, creates a new one
append appends data onto existing table
-f <shape_file>
the shape file or project to translate
-l <table,column>
target table and column for the geometry data
-D <database>
target database name
-u <username>
username for RDBMS
-p <password>
password for RDBMS
[Options] values are not necessarily required:
-s <server_name>
name of server with database
-port <port_number>
the port to connect to on the server
-ufi <column_name>
specify the name of the UFI field (unique ID)
-seq <sequence_name>
specify the sequence to use for the spatial data unique IDs
-a none
attributes mode
none no attributes will be transferred
all all attribtues will be transfered as found
file= file containing lines of the form:
<shape_attribute><space/tab><rdbms_column>
where
<shape_attribute> selects the column to be output
<rdbms_column> name of the column in RDBMS
-srid <id>
specify the Spatial Reference ID for the spatial data
(this must be set to use Spatial Reference Transformations)
-i [<level>] or -i rtree
create an index for the generated table
the <level> parameter is an optional integer
representing the depth of the quadtree created
if rtree is specified, the index created will be
an rtree
-c <commit_interval>
number of rows to commit after
-t <tolerance>
tolerance value for metadata
-r none
used to determine number of decimal places to round vertices to
if you use the tolerance-parameter option, specify the -t parameter before -r
-igc
ignore geometry collections
-sgc
split geometry collections
-sgd f
split geometry direction [forward | reverse]
-update-metadata <true/false>
update the Oracle Spatial Metadata table after loading data
-validate <true/false>
perform Oracle Spatial validation after loading data
-v
verbose mode on
-h or -?
display this help message
The main things I like about this tool are:
1. One step (no conversion to sqlloader form followed by a call to the sqlloader).
2. The ability to round the coordinates of the shapes in the shapefile by applying
the XY tolerance values held in the SDO_GEOM_METADATA table.
This is quite important because our editing package - due to double/single precision
issues - can actually move coordinates but those movements are sub the precision of
the actual data. By rounding to the nominate precision we can detect situations where
no actual change to the shape (and its attributes) was made and thus not create superfluous
revisions within the database.
3. It will correctly re-wind the coordinates of the outer/inner shells of polygons. This is
important as ESRI shapefiles are agnostic on the winding order: an outer shell coordinates
can be listed in either clockwise or anti-clockwise order.
4. You can specify the primary key (UFI) column (numeric) and an Oracle Sequence number such
that each new shape loaded can have its UFI assigned from that sequence.
Because of this flexibility, and the excellent support (it is a purchasable product) from the
developers, I can heartily recommend this loader to fellow Spatiallers. It is worth every
penny I spent on it. Try the free version on their website and if, like me, you like it,
purchase it!
regards
Simon

Hi Shuan,
As part of the zip file created for the next training course to be posted for Oracle Spatial on OTN (within the next few weeks) there is a free (unsupported, undocumented) version of a shape to sdo converter. This should work, but it is unsupported. It will create a layer that then needs to be migrated into 8.1.6 format.
If you need it quite soon send email to [email protected] and I can get it to you.
Hope this helps,
dan

Oracle Spatial and Oracle Forms

Hi,
Does anyone have experience with Oracle Spatial and Oracle Forms?
I have generated a form, which is based on a view. The view uses the mdsys.sdo_relate operator. Somehow I am unable to get the form to perform (to get one record it takes over 20 minutes). While useing sql-navigator to process the same statement it seems no problem. The query that also uses the view, is then processed in 10 seconds.
I also noticed that when text-functions like ' lower' of ' upper' are used to query the view, the query is processed within 15 seconds. If I don't use ' lower' or ' upper' it takes a long time (> 20 minutes) to process the query. Is it possible that this causes the bad performance of the form?
On metalink I have found that forms and spatial do not cooperate because of the pl/sql version that
forms6 uses. There is no solution presented, does anyone know of a work around?
My configuration is:
Oracle 8.1.7 on WIN2K @ PIII-800Mhz 256 Mb memory.
Formsbuilder 6
If requested I can post the queries that I have made.
With regards,
Gerjan Walrecht

Hello Priya,
Look into the following.
1. Book - Pro Oracle Spatial for Oracle Database 11g by r. Kothuri, A. Godfrind, E. Beinat. This book provides a nice introduction on Oracle Spatial concepts and have examples.
2. Look at the Oracle Spatial & Graph User Guide
2. Book - Applying and Extending Oracle Spatial by S. Greener and S. Ravada. This book provides hands on information for advanced oracle spatial application developers. Practical guide on hands-on examples, Data models and develop cross-vendor database solutions.
3. This oracle spatial forum, once you understand these concepts.
In the future consider Certification on Oracle Spatial 11g Certified Implementation Specialist.

Help define the requirements for an Oracle Spatial management tool

Hi,
We are developing a tool that, we hope, will be indispensable for all Oracle Spatial and Locator dbas/users. We've released version 1.0, but we need your help to define the requirements for the next version.
What features would you like to have in a management tool for your spatial databases?
The features we've got so far:
1. Viewing of vector data in a map + attributes
2. Loading from shapefiles
3. Exporting to shapefiles
4. Validating metadata, indexes and spatial data.
We are adding editing of vectors in the next version - basic stuff for add, update and delete.
But there must be a lot more. What do you find difficult to do in Oracle Spatial/Locator? What would you like in a tool such as this?
Any feedback either to myself or the forum is much appreciated.
cheers,
Andrew
[email protected]
PS If you like to have a look at what we have done so far, go to http://www.geometryit.com/products/spatialConsole.php

Andrew knows what I have asked for but for others to think about and to start
the ball rolling, here's what they are:
1. Ability to enter own SQL commands but with PARAMETERS for attributes
and shapes as in the following examples:
SELECT ...
FROM my_spatial_table a
WHERE a.ATTRIBUTE = :attr
AND MDSYS.SDO_RELATE(a.shape,:polygon,'mask=anyinteract') = 'TRUE'
When executed the attribute value is asked for via a input box (data type?)
and the user is asked to define the SDO_GEOMETRY for the :polgygon parameter via mouse clicks on the screen.
Similarly, this would work for INSERT, UPDATE and DELETE...
INSERT INTO my_spatial_table (shape) values(:polygon)
The data type of an attribute parameter could be determined in two ways:
a) By querying the Oracle catalog;
b) By using a "PARAMETERS" command before the query as follows
PARAMETERS name type [(size)] [, name type [(size)] ...]
The PARAMETERS declaration has these parts:
name     The name of the parameter.
type     The type of the parameter.
size     The size of the parameter in characters or bytes.
2. When executing an SQL SELECT statement I would like the tool
to suggest the HINTS that are needed to improve performance.
3. Following on from 2, I would like to Tick an option that would return the
EXPLAIN PLAN that the query optimizer used when executing my query.
4. The tool has to support ALL Oracle's spatial vector data types.
5. It would be nice to be able to work with GeoRasters. Since Spatial Console
imports/exports shapefiles why not the same for rasters. However, the problem
with supporting foreign data formats is WHERE DO YOU STOP!!!!!
6. You could allow for the styling of the Spatial Console to be stored in the MapViewer catalogs or use the MapViewer catalogs when styling an Sdo_Geometry if it exists (I note that your tool extracts the SDO_METADATA
why not the MapViewer metadata as well)?
regards
S.

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.

Its all listed in Appendix B of the Oracle Spatial Developer's Guide. It varies a little from release to release so you'll need to check the guide for the database release you're on.

Oracle Spatial functionality with WFS

Hi all
My first post here so be gentle on me ;-)
This may be an obvious question but here goes ...
When using a WFS client can you access the full SDO_... SQL functions within Oracle Spatial? I've had a read of the WFS spec and it is all a bit vague on how the queries get passed through to the data store.
Also with the WFS locking, is this done at the web server level? If so how would that impact on any direct access to the database? A bit dangerous??
Appreciate any advice on WFS implemtations with a 9i back end. I want to retain the full native Oracle functionality and still deploy via WFS ... a pipe dream??
Thanks
Richard

Thanks for your response Andreas
Sorry, perhaps I wasn't clear, I realise the WFS client will never directly access the data source, that it is the WFS server that makes the request to the data store, not the client, but can the call be passed through to Oracle as native SQL?
I think I found the answer in the OGC Filter Encoding Imp Spec where it desribes in great detail the optional filter component of a WFS request. It desribes the CQL filter operators that include some spatial operators. These could, I understand, be translated from CGL and Feature based schema to SQL (in GML?) and relational based schema.
While I don't think at first glance that the spatial operators in CQL match all the Oracle SDO_ functions they probably go far enough for most normal users.
Am I on the right track?
Does anyone know of any work that has been done in this filter translation to SQL and if it has been implemented successfully anywhere.
I think the locks would still pose a problem, but that's for another day :-)
Thanks
Richard

Oracle Spatial 8.1.7 r-tree indexes

I don't think this problem is specific to r-tree indexes vs. quad-tree.
Even though I specify a tablespace other than the SYSTEM tablespace in Oracle Spatial Index Advisor when creating r-tree indexes, the index is still created in the SYSTEM tablespace. I don't want my spatial indexes in the SYSTEM tablespace!
select tablespace_name from user_indexes where index_name = 'GPS_IDX';
TABLESPACE_NAME
SYSTEM
Here is the sql statement that Spatial Index Advisor constructed:
create index gis.gps_idx on gis.gps (geometry) indextype is mdsys.spatial_index parameters ('sdo_indx_dims=2');
I was not able to issue this sql from worksheet with the tablespace option added. Is there a way to do that?
In Spatial Index Advisor, if I don't select the geometry column, then the sql is constructed with the tablespace option added, but when I select the geometry column, it removes it from the sql.
Can anybody shed some light on how to do this?
thanks
Dave

Spatial creates an index entry in the system tablespace but realy creates the spatial index in the tablespace you gave it. To verify it execute the select:
select table_name,tablespace_name
from user_tables
where table_name like 'spatial_table%';
It will return your table_name plus the spatial index table created for it.
The table_name will look something like this:
spatial_table_SX_FL10$.
spatial_tables beeing your spatial table.
You can query the same for the indexes built on that previous table.
select index_name,tablespace_name
from user_indexes
where table_name = 'SPATIAL_TABLE_SX_FL10$';
The two index names would look like:
spatial_table_sx_fl10$B1
spatial_table_sx_fl10$B2
They should be created in the tablespace mentionned in your tablespace clause when creating the spatial index.
Hope this helps

Oracle Spatial 10g R2 Java API

Hi All,
I have a JAVA tool said to be written for Oracle Spatial 10g R2 Java API which uses for example the class oracle.spatial.georaster.JGeoRaster. I have to port it to 11g R2. The tool is definitely written for an earlier version, because compilation fails on for example JGeoRaster.getProperties() method which is not present in the new API. For this new API I have a fine Javadoc documentation here:
http://download-llnw.oracle.com/docs/html/E11829_01/
I have searched for a similar one for 10g R2 but found only like
http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14373/toc.htm
which misses the oracle.spatial.georaster package. Is there such a package and if so, where can I find docs for it?
thank you in advance, best regards: Balázs Bámer

Hi Balázs,
the GeoRaster Java API was first released with 11gR2. Your first link points to that, or this link:
http://download.oracle.com/docs/cd/E11882_01/appdev.112/e11829/toc.htm
your second link points to 10g Oracle Spatial Java API, which doesn't include any GeoRaster related API. your tool might have been developed based on the old INTERNAL georaster jar file, which is not supposed to be used by your java program. But if you do want the api doc, you can run javadoc or jdeveloper to find out the api from the old sdogr.jar file.

Oracle Spatial system requirements

Hi Experts,
I have a 32bit window 2003 server with 8G memory (PAE added to *g from 2G) with 4 CPU.
we use oracle 10GR4 suppour in stream.
Based on application, I need to install Oracle Spatial ( Actually, I can saw Oracle Spatial object in sysaux tablespace).
I could not find how many system resource requirement to support Oracle Spatial future.
ALso How to check Oracle Spatial is installed into system?
Thanks for HELP!!
JIM

You can see what kind of options you have with:
select * from dba_registry;
Do you really need Oracle Spatial or just the free subset Oracle Locator?

Oracle spatial datasets

Are there any sites from where i can get spatial data that can be downloaded to Oracle Spatial. I am doing project on spatial datawarehousing, so need some real data on climatic conditions for some span of time. I have searched a lot on google but can not find a good one. May be you can help me
thanks

All you can do is find sites that have shapefiles or GML for download
and then use the appropriate loader to put into Oracle.
There are NO sites that I know of that make data available in Oracle exporter format.

Oracle spatial 11g - 3D-Geometry and KML-Export

Hi,
I'm currently working with an Oracle Spatial 11g - database and there with 2d- and 3d-geometries. With this Version you can extrude 2d's to 3d's and calculate their volumes. This works fine.
The problem is to save the extruded areas as 3d-geometries in a specific table. Enclosed you will find the SQL-Code of the current workflow:
*1. Create tables for the 2d- and 3d-geometries (incl. metadata and spatial index)*
-- table for 3d-geometry
CREATE
TABLE ta_geb(
geom MDSYS.SDO_GEOMETRY
,area NUMBER(12,3)
-- metadata 2D
INSERT INTO USER_SDO_GEOM_METADATA (TABLE_NAME, COLUMN_NAME, DIMINFO, SRID)
VALUES
     'ta_geb',
     'geom',
MDSYS.SDO_DIM_ARRAY
(MDSYS.SDO_DIM_ELEMENT('X',4439900.00, 4440020.00, 0.005),
MDSYS.SDO_DIM_ELEMENT('Y', 5664050.00, 5664130.00, 0.005)
31468
-- spatial index 2D
CREATE
INDEX ta_geb_index ON ta_geb(geom) INDEXTYPE IS MDSYS.SPATIAL_INDEX;
-- table for 3d-geometry
CREATE
TABLE ta_3dgeb(
geom3d MDSYS.SDO_GEOMETRY
-- metadata 3D
INSERT INTO USER_SDO_GEOM_METADATA (TABLE_NAME, COLUMN_NAME, DIMINFO, SRID)
VALUES
     'ta_3dgeb',
     'geom3d',
MDSYS.SDO_DIM_ARRAY
(     MDSYS.SDO_DIM_ELEMENT('X',4439900.00, 4440020.00, 0.005),
     MDSYS.SDO_DIM_ELEMENT('Y', 5664050.00, 5664130.00, 0.005),
     MDSYS.SDO_DIM_ELEMENT('Z', 0, 200, 0.005)
31468
-- spatial index
CREATE
INDEX ta_3dgeb_index ON ta_3dgeb(geom3d) INDEXTYPE IS MDSYS.SPATIAL_INDEX PARAMETERS ('SDO_INDX_DIMS=3');
*2. insert 2d-geomtry*
INSERT
INTO
ta_geb
VALUES
MDSYS.SDO_GEOMETRY(

*3. calculate volume of the extruded area*
SELECT SDO_GEOM.SDO_VOLUME(SDO_UTIL.EXTRUDE(

     SDO_NUMBER_ARRAY(10),
     'false', --validation
     0.005),0.005)
from ta_geb;
This works fine so far. Now I wanna insert the extruded geometry (now 3D) in the table ta_3dgeb. All my attempts were in vain...
*4. insert extruded geomtry*
INSERT
INTO
ta_3dgeb
select
SDO_UTIL.EXTRUDE(
          GEOM,
          SDO_NUMBER_ARRAY(0),
          SDO_NUMBER_ARRAY(10),
          'false', --validation
          0.005)
from ta_geb;
I got the following error message after executing this Code:
ORA-29875: failed in the execution of the ODCIINDEXINSERT routine
ORA-13365: layer SRID does not match geometry SRID
ORA-06512: in "MDSYS.SDO_INDEX_METHOD_10I", line 709
ORA-06512: in "MDSYS.SDO_INDEX_METHOD_10I", line 225
Then I tried to change something on the metadata and spatial indices, wihtout success. Does anyone has advices to solve the problem??
Afterwards I would like to export the 3d-geometry in a KML file to visualize it in Google Earth. Therefore oracle provides a tool. But I didn't managed it to export the geometry. Any hints for the KML export or are there any other tools alternatively??
Thanks for any suggestions!
Regards

Extrude does not automatically populate the SRID for the resulting geometry as there may not be a 3D equivalent of the 2D SRID defined
in the DB.
So the extruded geometry comes out without the SRID. In your case, since you are creating an index on the ta_3dgeb table
before inserting the extruded data, it is causing this failure.
So drop the index on the ta_3dgeb table and do the inserts into it.
Then you can manually update the geometries with the SRID if there is a corresponding 3D SRID for 31468.
Otherwise, you can use 31468.

Oracle Spatial book sample application

Hi all,
On Monday I received the Oracle Spatial book and I would like to post a topic about it. First of all I would like to congratulate the authors for their huge effort doing this excellent book. I think it will be very useful to the people that works with Spatial.
Next, my question is about the sample application showed in chapter 12 (SampleApplication.jsp). I run correctly mapviewer in my server and I can do the other examples, nevertheless when I want to start this application I recieve this error message about 'jdbc/spatial10g not found' in my web browser:

I am using Java 2 Runtime Environment version 1.4.2_02 and I think I have correctly configured the shared libraries in the oc4j server (sdoapi.jar, sdonm.jar, ojdbc14.jar, etc.). Anyway, I think I will be missing something but I don't know what.
I would be very grateful if somebody could help me.
Juan M.

Hi Juan
Thanks for purchasing our book, and thanks also for the kind words.
I think I know what that problem is.
The application uses the network API. That API needs a database connection for the initial loading of the network. The connection used is provided by OC4J. This is done in the following code lines in the SampleApplication.jsp:
// Get JDBC database connection
InitialContext ic = new InitialContext();
DataSource ds = (DataSource) ic.lookup("jdbc/"+dataSource.toLowerCase());
Connection conn = ds.getConnection();
// Load network
net = NetworkManager.readNetwork(conn, networkName);
In other words, for this to work, you need a datasource defined for OC4J, called "jdbc/spatial10g" (since dataSource is defined by default to be "SPATIAL10G".
To define the datasource, refer to chapter 11, page 499, at the bottom of the page. You need to add the following to your data-sources.xml config file ($OC4J_HOME/j2ee/home/config/data-sources.xml):
<data-source
class="com.evermind.sql.DriverManagerDataSource"
name="spatial10g"
location="jdbc/spatial10gCore"
xa-location="jdbc/xa/spatial10gXA"
ejb-location="jdbc/spatial10g"
connection-driver="oracle.jdbc.driver.OracleDriver"
username="spatial"
password="spatial"
url="jdbc:oracle:thin:@localhost:1521:orcl101"
inactivity-timeout="30"
/>
(Adapt the url parameter to match your database definition)
Thanks for pointing out this problem. We will update the errata page (http://www.apress.com/book/errataDisplay.html?bID=315&sID=2374) with clearer instructions.

Oracle Spatial Performance with 10-20.000 users

Does anyone have any experience when Oracle Spatial is used with say 20.000 concurrent users. I am not interested in MapViewer response time, but lets say there is:
- an app using 800 different tables each having an sdo_geometry column
- the app is configured with different tables visible on different view scales
- let's say an average of 40-50 tables is visible at any given time
- some tables will have only a few records, while other can hold millions.
- there is no client side caching
- clients can zoom in/out pan.
Anwers I am interested in:
- What sort of server would be required
- How can Oracle serve all that data (each Refresh renders the map and retrieves the data over the wire as there is no client side caching).
- What sort of network infrastructure would be required.
- Can clients connect to different servers and hence use load balancing or does Oracle have an automatic mechanism for that?
Thanks in advance,
Patrick

Patrick, et al.
There are lots of things one can do to improve performance in mapping environments because of a lot of the visualisation is based on "background" or read-only data. Here are some "tips":
1. Spatially sort read-only data.
This tip makes sure that data that is close to each other in space are next to each other on disk! Dan gave a good suggestion when he referenced Chapter 14, "Reorganize the Table Data to Minimize I/O" pp 580- 582, Pro Oracle Spatial. But just as easily one can create a table as select ... where sdo_filter() where the filtering object is an optimized rectangle across the whole of the dataset. (This is quite quick on 10g and above but much slower on earlier releases.)
When implementing this make sure that the created table is created such that its blocks are next to each other in the tablespace. (Consider tablespace defragmentation beforehand.) Also, if the data is READ ONLY set the PCTFREE to 0 in order to pack the data up into as small a number of blocks as possible.
2. Generalise data
Rendering spatial data can be expensive where the data is geometrically detailed (many vertices) esp where the data is being visualised at smaller scales than it was captured at. So, if your "zoom thresholds" allow 1:10,000 data to be used at 1:100,000 then you are going to have problems. Consider pre-generalising the data (see sdo_util.simplify) before deployment. You can add multiple columns to your base table to hold this data. Be careful with polygon data because generalising polygons that share boundaries will create gaps etc as the data is more generalised. Often it is better to export the data to a GIS which can maintain the boundary relationships when generalising (say via topological relationships).
Oracle's MapViewer has excellent on-the-fly generalisation but here one needs to be careful. Application tier caching (cf Bryan's comments) can help here a lot.
3. Don't draw data that is sub-pixel.
As one zooms out objects become smaller and smaller until they reach a point where the whole object can be drawn within a single pixel. If you have control over your map visualisation application you might want to consider setting the SDO_FILTER parameter "min_resolution" flag dynamically so that its value is the same as the number of meters / pixel (eg min_resolution=10). If this is set Oracle Spatial will only include spatial objects in the returned search set if one side of a geometry's MBR is greater than or equal to this value. Thus any geometries smaller than a pixel will not be returned. Very useful for large scale data being drawn at small scales and for which no selection (eg identify) is required. With Oracle MapViewer this behaviour can be set via the generalized_pixels parameter.
3. SDO_TOLERANCE, Clean Data
If you are querying data other than via MBR (eg find all land parcels that touch each other) then make sure that your sdo_tolerance values are appropriate. I have seen sites where data captured to 1cm had an sdo_tolerance value set to a millionth of a meter!
A corollary to this is make sure that all your data passes validation at the chosen sdo_tolerance value before deploying to visualisation. Run sdo_geom.validate_geometry()/validate_layer()...
4. Rtree Spatial Indexing
At 10g and above lots of great work went in to the RTree indexing. So, make sure you are using RTrees and not QuadTrees. Also, many GIS applications create sub-optimal RTrees by not using the additional parameters available at 10g and above.
4.1 If your table/column sdo_geometry data contains only points, lines or polygons then let the RTree indexer know (via layer_gtype) as it can implement certain optimizations based on this knowledge.
4.2 With 10g you can set the RTree's spatial index data block use via sdo_pct_free. Consider setting this parameter to 0 if the table/column sdo_geometry data is read only.
4.3 If a table/column is in high demand (eg it is the most commonly used table in all visualisations) you can consider loading (a part of) the RTree index into memory. Now, with the RTree indexing, the sdo_non_leaf_tbl=true parameter will split the RTree index into its leaf (contains actual rowid reference) and non-leaf (the tree built on the leaves) components. Most RTrees are built without this so only the MDRT*** secondary tables are built. But if sdo_non_leaf_tbl is set to true you will see the creation of an additional MDNT*** secondary table (for the non_leaf part of the rtree index). Now, if appropriate, the non_leaf table can be loaded into memory via the following:
ALTER TABLE MDNT*** STORAGE(BUFFER_AREA KEEP);
This is NOT a general panacea for all performance problems. One should investigate other options before embarking on this (cf Tom Kyte's books such as Expert Oracle Database Architecture, 9i and 10g Programming Techniques and Solutions.)
4.4 Don't forget to check your spatial index data quality regularly. Because many sites use GIS package GUI tools to create tables, load data and index them, there is a real tendency to not check what they have done or regularly monitor the objects. Check the SDO_RTREE_QUALITY column in USER_SDO_INDEX_METADATA and look for indexes with an SDO_RTREE_QUALITY setting that is > 2. If > 2 consider rebuilding or recreating the index.
5. The rendering engine.
Whatever rendering engine one uses make sure you try and understand fully what it can and cannot do. AutoDesk's MapGuide is an excellent product but I have seen it simply cache table/column data and never dynamically access it. Also, I have been at one site which was running Deegree and MapViewer and MapViewer was so fast in comparison to Deegree that I was called in to find out why. I discovered that Deegree was using SDO_RELATE(... ANYINTERACT ...) for all MBR queries while MapViewer was using SDO_FILTER. Just this difference was causing some queries to perform at < 10% of the speed of MapViewer!!!!
6. Consider "denormalising" data
There is an old adage in databases that is "normalise for edit, denormalise for performance". When we load spatial data we often get it from suppliers in a fairly flat or normalised form. In consort with spatial sorting, consider denormalising the data via aggregations based on a rendering attribute and some sort of spatial unit. For example, if you have 1 million points stored as single points in SDO_GEOMETRY.SDO_POINT which you want to render by a single attribute containing 20 values, consider aggregating the data using this attribute AND some sort of spatial BUCKET or BIN. So, consider using SDO_AGGR_UNION coupled with Spatial Analysis and Mining package functions to GROUP the data BY <<column_name>> and a set of spatial extents.
6. Tablespace use
Finally, talk to your DBA in order to find out how the oracle database's physical and logical storage is organised. Is a SAN being used or SAME arranged disk arrays? Knowing this you can organise your spatial data and indexes using more effective and efficient methods that will ensure greater scalability.
7. Network fetch
If your rendering engine (app server) and database are on separate machines you need to investigate what sort of fetch sizes are being used when returning data from queries to the middle-tier. Fetch sizes for attribute only data rows and rows containing spatial data can be, and normally are, radically different. Accepting the default settings for these sizes could be killing you (as could the sort_area_size of the Oracle session the application server has created on the database). For example I have been informed that MapInfo Pro uses a fixed value of 25 records per fetch when communicating with Oracle. I have done some testing to show that this value can be too small for certain types of spatial data. SQL Developer's GeoRaptor uses 100 which is generally better (but this one can modify this). Most programmers accept defaults for network properties when programming in ADO/ODBC/OLEDB/JDBC: just be careful as to what is being set here. (This is one of the great strengths of ArcSDE: its TCP/IP network transport is well written, tuneable and very efficient.)
8. Physical Format
Finally, while Oracle's excellent MapViewer requires data its spatial data to be in Oracle, other commercial rendering engines do not. So, consider using alternate, physical file formats that are more optimal for your rendering engine. For example, Google Earth Enterprise "compiles" all the source data into an optimal format which the server then serves to Google Earth Enterprise clients. Similarly, a shapefile on local disk to the application server (with spatial indexing) may be faster that storing the data back in Oracle on a database server that is being shared with other business databases (eg Oracle financials). If you don't like this approach and want to use Oracle only consider using a dedicated Oracle XE on the application server for the data that is read only and used in most of your generated maps eg contour or drainage data.
Just some things to think about.
regards
Simon
