Spatial talk at IOUG Collaborate '08

I'd like to invite everyone here to a talk I will be giving at IOUG Collaborate '08 in April. The presentation will be for Spatial beginners and it's titled "Getting Started with Oracle Spatial Without Stopping to Ask Directions." (OK, I was told to try to make a little joke.)
My intended audience is experienced Oracle developers who have never used Spatial and want enough information to get started.
Please come up and introduce yourself afterwards.

Session #414 Monday April 14 1:00pm

If you are wondering about topics...this forum and its threads provide plenty of possibilities. You can see many of the recurring questions and topics with variations on a theme that would really attract a crowd.
Off the top of my head - topics on: AJAX functions/functionality, javascript, tabular forms and dependent drop-down lists, manual tabular forms, pdf printing and report templates without BI Publisher, report and tabular form - dynamic column formatting and attribute setting...I'm sure you can think of many more.
Any of these would draw a crowd and might just justify attending the conference for some APEX developers who need to know "how" and can network with those who know how.

OBIEE Analytics/Reporting Solutions for E-Business Suite
Audio Dial-In: 888 967 2253 Audio Meeting ID: 572994 Audio Meeting Passcode: 334451

BIWA Wednesday TechCast Series - Sixth Event!
This presentation will showcase different options for OBIEE-based Analytical Reporting such as:
1) Oracle BI Applications for supported Oracle E-Business Suite Modules and other Oracle Applications.
It will include real world experiences for implementing BI Apps Version 7.9.6
2) Custom OBIEE Development against E-Business Suite (when no BI apps are available)
3) Migration of Discoverer EUL to OBIEE RPD using Migration Utility
While OBIEE and BI Apps are clearly the strategic analytics reporting direction from Oracle, only certain Analytics applications are available. Sometimes all customer needs for BI reporting may not be met by these pre-built analytics. For instance, JD Edwards has pre-built ETL connectors only for Financial Analytics. While more BI Apps and ETL connectors are in the pipeline, how can users meet their reporting needs today as they go live in near future? In this session, we will look at several short and medium term solutions without deviating from the long term strategic goal of using pre-built BI applications to reduce the overall risk.
Several real life situations will be evaluated with demonstration of the steps involved such as how to Migrate Discoverer reports to OBIEE with the highest degree of automation. Likewise, we will cover how DBI views be used for custom OBIEE reporting.
Presenter: Shyam Varan Nath is an OBIEE Architect for IBM Global Business Services with extensive experience in implementing OBIEE and BI Apps. He has worked on several Oracle Data Warehousing Projects for customers including Citigroup, Air Force, Land O'Lakes, and Blue Cross Blue Shield Association. Shyam has been a Certified Oracle DBA since 1998 and has 18 years of industry experience. He is a regular speaker at BIWA Summit, IOUG/Collaborate, Regional User Groups and Oracle Openworld since 2003. Shyam has also worked at Oracle (BI Consulting Practice) and Deloitte Consulting. Currently, he is the top expert in Oracle OBI apps Forum, in terms of user awarded points. Shyam is also the Founder and President of BIWA SIG.

Does SQL Server agent/IIS plugin support User-Defined metrics?

Hi,
Does anyone know if there is a way to add a user-defined metric that connects to a SQL Server database?
Thanks

Recently, I released a full MySQL plug-in, for example - http://www.pythian.com/blogs/mysql-plug-in-for-oracle-grid-control
For me it's not very difficult but it takes some time to get used to.
I did presentations on creating Management plug-ins and couple articles in IOUG SELECT Magazine. The latest presentation and whitepaper is here - http://www.pythian.com/blogs/466/ioug-collaborate-07-oracle-10g-grid-control
Official extensibility guide has much more details and is priceless reference but, still, not everything is documented there.

OEM Extension for MySQL

Hi,
I'm looking for an OEM extension to Monitor (and/or manage) MySQL databases. or another option to monitor MySQL databases through EOM
Guido

I did a presentation during UKOUG 06 and part of it was a MySQL plug-in (very basic but can serve as goos basis). You can find it here - http://www.pythian.com/blogs/309/ukoug-2006-presentations-available (second presentation + sample). A bit older article is here - http://blog.oracloid.com/2006/06/extending-oracle-enterprise-manager-10g-article/
I'll be presenting about it on IOUG COLLABORATE in case you are there.

Project UDF Vs Activity UDF

Hello Friends,
Following is my query.
Project UDF can have formulas and can be seen / Pulled in P6 Dashboard- Project Statistics but on other side ,Activity UDF does not have any formulas and can't be pulled in P6 Dashboard - Project Statistics. Why ?
Requirement: I want to have PO Release and Its Status for each procurement activity . I can put that in primavera, but if i want to prepare dashboard , I can't pulled that information in any standard dashboard of Primavera EPPM 8.2 .
Any thoughts?
Note : I don't want to use BI for reporting.
Also can anyone enlighten me , what is difference between actual usage for Project UDF , WBS UDF and Activity UDF as implementation point of view.

looked at one of powerpoint presentation from a user group
James,
Yes. I believe you actually meant my presentation. If you looked at the presentation of UKOUG - here (http://www.pythian.com/blogs/466/ioug-collaborate-07-oracle-10g-grid-control) is the improved version and it also has a white paper - much easier to follow than simple PDF slides. I do include a fully functioning MySQL target example. I'm actually working on improving it but it takes time as I'm quite busy.
No collection on cumulative counters
To collect stats based on cumulative counters you have to calculate the rate. I.e. if you have counter that shows you number of physical IOs since instance startup, you will have to calculate a difference between two collections divided by the size of the period. This would give you meaningful results.
You can't do that with UDM.
Limited collection mechanisms ?
Only very simple SQL and script based collections are available with UDM.

Sebastien Lanoe, Product Marketing Manager, Lorienne SA
The production of maps out of GIS databases is often a challenging process. Lorienne innovates with a new map production environment for map creation, map publication and map updates from Oracle Spatial, with a focus on high quality, production cost, data integrity and diversification of map products across media. The case study with Tele Atlas data stored in Oracle Spatial will address the benefits, the level of quality, the efficiency of the production process and its dedicated user-friendly environment.
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.
Complete eGovernment solution at City of Bolzano
Stefan Putzer, CreaForm
Giulio Lavoriero, Director of Engineering, CreaForm
The City of Bolzano, Italy has a unique, complete editing and publishing environment for geographical data. The Oracle Spatial-based enterprise editing environment supports import and export into geospatial tools from Bentley and ESRI, and network modeling from Oracle Spatial. Data is shared with GeoJAX, an easy-to-use geographical web browser that uses the Oracle MapViewer framework in combination with J2EE and AJAX for browsing Oracle Spatial data. This provides a flexible viewer supports spatial queries, and can be fully customized (style and functionality). Users can easily import any kind of geographical data from an ESRI file, edit it with a CAD precision functionality and make those data visible to anyone via the web in a very short time.

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.

Spatial tables in Data warehouse database or separate?

Hi all,
I have a question from a customer who's asking what the recommendation is of storage of the spatial tables and the warehouse tables.
Should they reside on the same database for best performance or doesn't it matter where the spatial tables are located.
Is there any official recommednation from Oracle on this?
Best regards,
Hakan

Hi Hakan,
it's not easy to give a quick answer here.
a) you want to compare warehouse tables with spatial tables
To answer this very well you should define what is a warehouse table and what is a spatial table. In this forum you will get for spatial tables the definition "A spatial table is a table with one or more columns of type SDO_GEOMETRY". How do you define a spatial table and how do you define a warehouse table?
b) you ask for performance
Performance is not depending only on table type. Performance is depending on a lot of steps. For example on the work which has to be done to answer the question, can data read from buffer cache or must they be read from physical devices, execution plan .....
I don't know if there is a official statement from Oracle which is usefull to answer your query.
Can you ask a little bit particular please?
In my experience there it is not adviseable to store tables in different databases (instances) when I have to query it together. If you split the tables in different instances, the execution has much more overhead because you have to talk to 2 instances and it will very hard for the optimizer to find the best execution plan.

U. Martin

Best Practice for Storing Spatial Data in Multiple Projections?

From what I've been able to determine MS SQL can't do reprojections is that correct? Assuming it is, the state of Washington requires that our GIS data be managed in Washington Stat Plane South
but for our web mapping sites need the data in Web Mercator. Is it OK then to have two geometry columns in a spatial enabled table, say a county table, one in WSPS and the other in WM?
I’m coming at this from a 30 year background in GIS using ESRI software.
Usually we would store the shape / geometry in one projection and project it to other on the fly when needed.
That way there is only one definitive source. I don’t see a way to do this in MS SQL.

Hi Scott.
Storing two columns of spatial data is fine in SQL Server. And you are correct that there is no built-in reprojection in SQL Server, most folks do that as part of data loading. There was talk of porting parts of ogr2ogr to SQLCLR, but I don't think anyone
did that.
Cheers, Bob
