Oracle spatial data compression (using advance compression).

What are the bast practice for oracle spatial to compress data using advance compression).
ver. 11.2.0.3

Details about Advanced Compression can be found in:
Oracle E-Business Suite Release 12.1 with Oracle Database 11g Advanced Compression (Doc ID 1110648.1)

Keep the Oracle Spatial data in memory

I can keep any database tables in memory (for fast access) using Oracle Coherence (the In Memory Data Grid).
Now I want to store Oracle Spatial data in memory, is it possible?

I think it is possible. The difference is it is not easy to recreate some Spatial-related functions and procedures in caches. But you can invoke them from the in-memory applications using Oracle Spatial Java API.

Cannot edit Oracle Spatial data

Hello,
I am running into some problems with my Oracle Spatial data. Maybe somebody has some insight. Here's what is going on:
1) I am able to connect to and view the data in uDig but I cannot edit the data and also the data shows up in the table of contents with a line symbol even though it is polygon data (it renders correctly in the map as polygons). I try using the 'Create Polygon Geometries' tool and it errors saying 'Create Polygon Tool' cannot operate on current layer.
2) When I try testing edits through WFS-T it errors and tells me that the table is read only.
The table is in the USERS tablespace and I have verified that it is read/write. I also set object permissions on the user: ALTER, DELETE, INSERT, SELECT, UPDATE
Am I missing something obvious? Anyone else have this problem? Thanks a lot for any ideas anyone has.

My apologies for the confusion. My insert statement DID work just fine. I just wasn't seeing it...probably because I was querying the table in Enterprise Manager DB Control and it looks like it takes some time to refresh. So it appears that user permissions are not the issue.
I have used two data loading methods:
Before loading data, I needed to create a user defined coordinate reference system:
1 create projection operation for my custom projection
2 configure projection parameters
3 create the projected CRS in mdsys.sdo_coord_ref_system
First data load steps
1 shp2sdo.exe my_shapefile my_table -g geom -s 1000002 -v
2 execute my_table.sql
3 execute sqlldr.exe
4 EXECUTE SDO_MIGRATE.TO_CURRENT('my_table','GEOM');
5 CREATE INDEX my_table_index ON my_table(geom) INDEXTYPE IS MDSYS.SPATIAL_INDEX;
Second data load steps:
1 open up MapBuilder, make a connection, and go through the Import Shapefile wizard. MapBuilder automatically creates a spatial index.
Does it appear that I am missing any steps or doing anything obviously wrong that would be causing me to not be able to edit the data through clients such as uDig or WFS-T?

Keep Oracle spatial data in memory

Can I keep Oracle Spatial data (including metadata and related functions and procedures) in memory using TimesTen?

It depends what form the data takes. TimesTen does not support any spatial types, only regular relational data types. Also, TimesTen does not support any of the Oracle spatial functions.
In general this is not possible.

Keep Oracle Spatial data in Coherence Caches?

Can I keep Oracle Spatial data in Coherence Caches?

You can store the Oracle Spatial data in Coherence caches. But creating Spatial indexes in Coherence neeeds too much effort, I guess. How do you create the Spatial geocoding package, map symbols, map styling rules and Spatial network model?

Acquiring Oracle Spatial Data through WFS

Hi,
I have been researching for awhile and am slightly confused.
I have Oracle Spatial 11g with geometry data and would like to be able to retrieve that data through a WFS to serve to a viewing application.
Here's where I am confused:
1) Spatial has a WFS service which needs to be configured. If I were configure that, would I be able to access the data through URL getFeature commands? The documentation I see for them has the getFeature requests in the form of XML files so I am not sure if I can do that. Also it seems like the service is returning .log files but I think I would want GML...
If this is the option I should take, the tutorial to setup OC4J and the Web Services are for a Linux machine (http://www.oracle.com/technology/obe/11gr1_db/datamgmt/spatialws/spatialws.htm) -- Is there one for Windows 64bit?
2) Do I need another "application layer" to enable this URL support? I know MapServer can use URL requests.. can I just run this against the data in my DB and forget about the Oracle WFS?
3) MapViewer seems to work with WFS Themes and handle requests through Java and SQL.. is this another option?
I am basically confused as to where everything sits and what I should be focusing on to get my Spatial data out of the DB through a WFS. Any assistance on this matter would be greatly appreciated!
Thanks!

Any help debugging this issue would be greatly appreciated:
As per the documentation:
http://localhost:8888/SpatialWS-SpatialWS-context-root/wfsservlet?request=GetCapabilities&service=wfs&version=1.0.0
:this get request should return the capabilities info however I receive this error message instead in the browser:

[Begginer] How to view my Oracle spatial Data ?

I'm a begginer , I know how to make and insert Spatial data but , i want to see it like map , how ?
Please tell me the software and good documentation ?

Try using MapViewer. It is downloadable from OTN:
http://otn.oracle.com/products/spatial
then click on the software button to find instructions and the MapViewer software.

Interfacing Oracle spatial data with ArcView 9

Hello,
I'm trying to take my spatial data in Oracle which has SDO_GEOMETRY fields, and have it display in ArcView. I know I have to do something with SDO_GEOMETRY, but I'm not sure how. I've been reading that 3rd party tools can be used. Is this the only way, or is there something else I can do?
Thanks much,
Nora

the way i use is through arcsde. register the oracle table with sde and then you can view it in any arc software.
there is another way through direct connect. i havent used it but you can find some help on esri website.

Update Oracle spatial data!

Hi everybody!
i'm new in Spatial, i want to update data in Oracle spatial to make a map of Asia with couty, street, state...
Could any body tell me where source to update.
Thanks so much.

I do not understand.
Do You need to update Your own tables, or You need to find reference data for Asia which You intend to import into Oracle Spatial?
If You are seeking for reference data for Asia, then You need to find it for every country. I doubt that exist for entire continent.
If You have Your own table and want to extend it with conty, street etc, You can use simple ALTER statement, like:
ALTER TABLE <table_name> ADD (
state VARCHAR2(25),
county VARCHAR(25)
);

BI & Oracle XI data exchanges using WEBServices (into both sides)

Hello,
Would you be so kind and give me suggestions.
We have:
BI 7 server Oracle Exchange Infrastructure Oracle DB server
Our client wants to implement this data exchange solution:
Scenario A: i have load data to BI from Oracle DB
My steps are: from BI i have to call WEBService from Oracle Exchange Infrastructure when Oracle Exchange Infrastructure calls WEBService from Oracle DB and Oracle DB returns data set to BI via Oracle Exchange Infrastructure.
How to schedule job for calling WEBServices from Oracle Exchange Infrastructure? What have i configure in BI?
Scenario B: Application based on Oracle DB wants to get data from BI
Steps are: Oracle DB calls WEBService from Oracle Exchange Infrastructure when Oracle Exchange Infrastructure calls WEBService from BI and BI sends data to Oracle DB via Oracle Exchange Infrastructure.
BI offers Open Hub Service for data distribution from BI, but I didnt find description how to distribute data using WEBServices.
Is is possible to implement Scenario A and Scenario B in BI with standard tools.
Could you give me detailed answers(step-by-step what I have to do)?
Thanks in advance.
Best Regards,
Arunas Stonys

Arunas,
Quite an interesting landscape....
Also what do you mean by standard tools ?
Option A :
You can use the XML datasource for the same and once the XML data source is called , the data enters the Delta Queue in the BI server and from there you can use the normal infopackage / real time daemon to load data into your cubes / DSO. The XML datasource works on SOAP and this has to be supported by the Oracle XI.
Option B:
Slightly more trickier since you are hitting the BI server directly....
I am not sure if an infospoke can be a web service but some of the ways this could be done is :
a. Have an Func Module which acts as a web service and have that FM return the data
b. Have SAP XI inbetween to do the same
Also on the landscape- depending on the nature of data loads / data requests - if BI-Oracle is more - you can look at having SAP XI there instead....
Arun
Hope it helps....
P.S I would also suggest that you post the same in the Enterprise SOA forums / enterprise web services and people like Karthik Iyengar , Durairaj etc can respond to the same in a much better way that what I am able to give you right now...

How to get list of indexes compressed using Key Compression !!

Hi....Experts.
How can i find out INDEXES compresses in my system using Index Key compression as explained in Note #1109743
Ref : SAP Note 1109743 - Use of Index Key Compression for Oracle Databases
Ref : Find out INDEX type ?? for INDEX Key Compressions. !!!
(or)
I got a foolish question in my mind,
Rgds

Hi,
Check Section 17 of Note 1289494 - FAQ: Oracle compression
How do I determine which tables and indexes have active compression?
SELECT
OWNER,
INDEX_NAME,
NULL PARTITION_NAME,
PREFIX_LENGTH
FROM
DBA_INDEXES
WHERE
COMPRESSION = 'ENABLED'
UNION ALL
( SELECT
    INDEX_OWNER OWNER,
    INDEX_NAME,
    PARTITION_NAME,
    NULL PREFIX_LENGTH
FROM
    DBA_IND_PARTITIONS
WHERE
    COMPRESSION = 'ENABLED'
ORDER BY
OWNER,
INDEX_NAME;
Hope it helps.
Thanks

Dynamic table in Oracle report data model using laxical parameter is giving error Ora-00936: missing expression

Hi ,
I am using Oracle report 10G
And trying to create report with dynamic table

Can anybody advise to solve this issue.

Look in the Reports Builder Help:
If you want to use lexical references in your SELECT clause, you should create a separate lexical reference for each column you will substitute. In addition, you should assign an alias to each lexical reference.
Does adding the column alias solve the problem?

Basic vs Advanced Compression in Oracle 11g

Hi,
We are going to install Oracle 11gR2 in one new database server. Since the database will be used for Data Warehouse purposes and our company has rejected to pay licenses for "Oracle Advanced Compression", I wanted to know which options of "Basic Compression" are suitable for us, if we want to compress the biggest tables in our environment.
Thanks in advance for your feedback.
Regards,
Rubén

Hi;
OAC mean you need to pay extra money to oracle. We are using basic compression in our env. Please check this search. Check first 4 links which is explain already how&what basic compress
PS: This is installation related forum site. For your similar issue please use Oracle Discussion Forums » Oracle Database » General Questions forum part

Supported data types for BASIC compression.

Hi,
I am in the way of preparing a white paper for one of my customer on basic compression.
As per the URL below, it says that there is a separate compression method for LOB type objects.
http://docs.oracle.com/cd/E11882_01/server.112/e25494/tables.htm#CJAGFBFG
Now my question, apart from LOB type, can i use basic compression method for all other data types. Any restrictions. Thanks in-advance.
as per below URL, there is a different method for compressing LOB. They are talking about secure file LOBs not basic LOBS. what is the method for compressing normal/basic LOBs.
Using Oracle SecureFiles LOBs
Regards
DBA.

You can not compress normal/basic LOBs.
Compression and Deduplication on SecureFile LOB data requires the Advance Compression add-on.
Compression ratios are comparable to WinZIP/gzip. However, since this works on a block level, it may only be useful when the LOBs are significantly larger than your DB Block size (normally 8k)
YOU MUST RUN BENCHMARKS!!!!
BASIC and OLTP Compression apply to the table, not any particular column.
BASIC is only good for bulk load. (i believe it is 'free'.. but don't quote me.)
OLTP requires Adv. Compression.
