Oracle 9 spatial index export/import

Hi,
when exporting/importing a user via exp/imp I encounter a problem with the numeric characters encoding during creation of a spatial index.
Imp tool produces script like this:
"BEGIN "
"execute immediate 'INSERT INTO USER_SDO_GEOM_METADATA values (''POINTS'',''GEOMETRY'',mdsys.SDO_dim_array(MDSYS.SDO_DIM_ELEMENT(''X'',50000000,160000000,,005),MDSYS.SDO_DIM_ELEMENT(''Y'',450000000,600000000,,005)),,005) ' ; "
"COMMIT; END;"
Problem is with wrong representation of the numeric value '0.005' as ,005.
Originally, the index was created via
INSERT INTO USER_SDO_GEOM_METADATA
VALUES (
'points',
'geometry',
MDSYS.SDO_DIM_ARRAY(
MDSYS.SDO_DIM_ELEMENT('X',-125000000,-115000000, '0.005'),
MDSYS.SDO_DIM_ELEMENT('Y', 30000000, 42100000, '0.005')
NULL
Any hints how to reimport the index correctly?
Thanks,
Bogart

You might need to set the NLS_LANG environment variable to get character set conversion done on import (I don't know this unfortunately - it has never been a problem for me).
There is a section on character set conversions in the utilities manual.

Problem with oracle text indexes during import

We have a 9.2.0.6 database using oracle text features on a server with windows 2000 5.00.2195 SP4.
We need to export its data ( user ARIANE only ) and then import the result into another 9.2.0.6 database.
The import never comes to an end.
The only way to make it work is to use the "indexes=n" clause.
Then ( without the indexes ), we tried to create manually the oracle text indexes.
We get this error :
CREATE INDEX ARIANE.DOSTEXTE_DTTEXTE_CTXIDX ON ARIANE.DOSTEXTE (DTTEXTE)
INDEXTYPE IS CTXSYS.CONTEXT PARAMETERS('lexer ariane_lexer stoplist ctxsys.default_stoplist storage ariane_storage');
ORA-29855: erreur d'exécution de la routine ODCIINDEXCREATE
ORA-20000: Erreur Oracle Text :
DRG-10700: préférence inexistante : ariane_lexer
ORA-06512: à "CTXSYS.DRUE", ligne 157
ORA-06512: à "CTXSYS.TEXTINDEXMETHODS", ligne 219
We then tried to uninstall Oracle text and install it ( My Oracle Support [ID 275689.1] ). The index creation above still fails.
We also checked our Text installation and setup through My Oracle Support FAQ ( ID 153264.1 ) and everything seems ok.
Do we have to create some ARIANE* lexer preferences through specific pl/sql ( ctx_report* ? ) before importing anything from the ARIANE user ?
What do we need to do exactly when exporting data with oracle text features from one database to another given we used to restore the database through a copy of the entire windows files ?
Is there a specific order to follow to succeed an import ?
Thank you for your help.
Jean-michel, Nemours, FRANCE

Hi
index preferences are not exported, ie ariane_lexer + ariane_storage, only the Text index metada, thus the DRG-10700 from index DDL on target/import DB.
I recommend to use ctx_report.create_index_script on source/export DB, see Doc ID 189819.1 for details, export with indexes=N and then create text indexes manually after data import.

Oracle Spatial Index Advisor

Have tried to use subject and got an error when adding the table to analyze.
Error: Server object could not be created: server object could not be initialized: Non supported character set: oracle-character-set-171.
What's issue of this error? Does anyone know?

Hi Igor,
Not sure what the problem is.
This could be an NLS issue.
You might want to log a bug against
the Spatial Index Advisor with a small dump
file of your layer.
Also, can you make sure your entries
in USER_SDO_GEOM_METADATA are correct?
Thanks.

Oracle spatial Indexing

Hi Guru's
I am newby to Oracle spatial. Working as Database Admin.
I want information about spatial indexing like creation, maintenence ..etc.
It would be a great help if you can refer any relevant documents, articles or presentations.
Thanks in advance
Cheers
Antony

Welcome Antony
First place to start is the user documentation:
http://download.oracle.com/docs/html/B14255_01/toc.htm
start reading on the indexing here:
http://download.oracle.com/docs/html/B14255_01/sdo_intro.htm#sthref98
As an alternative/added value the Pro Oracle Spatial book is also a very good reference.
http://www.oracle.com/technology/products/spatial/htdocs/pro_oracle_spatial.html
there is also a second version for 11g.
For the maintenance, certainly from a DBA point of view, it is worthwhile looking at Radius Check. The lightweight free version offers an easy overview on the geometry tables, their metadata and their spatial indexes.
The professional version also gives Checks for invalid geometries with fixing capabilities.
On the Oracle Spatial Download page (http://www.oracle.com/technology/products/spatial/htdocs/spatial_partners_downloads.html), you can find the link second at the top to the webpage of Radius Check (http://www.1spatial.com/products/radius_check/index.php).
Good Luck

Tune oracle spatial index

Hi everyone,
how to tune spatial index in oracle? Pls advice
Thanks in Advance

That's a very open ended question. When posting questions on this forum you'll get better results if you have very specific questions. So do you have a specific spatial query which isn't performing well? If so then post as much information as you can about it.
- Exactly what version of Oracle database?
- What is the SQL query you're running - if possible include the explain plan
- What is your expected response time for the query?
- How much data is in the table and what kind of data is it
- Is possible provide some information about the use case behind the query you're running.
There are various techniques available to make spatial queries perform as you'd expect, but I'm not going to waste my time going through them here until you provide some useful information.
I'd recommend having a look at this presentation for some advice:
http://download.oracle.com/otndocs/products/spatial/pdf/ow_2009/spatial_oow09_tuning_and_best_practices2.pdf
Also have a look at this:

About Oracle 10g Data export/import

I have two DBs, let's call them AProd, BAcpt.
all tables/procedures/sequences etc. are defined same, only schema names are different, and the role names are different (e.g. In AProd, role 1 named as AProd_ROLE1, but corresponding role in BAcpt is named as BAcpt_ROLE1).
In order to use Aprod data to refresh BAcpt, in OEM, I established a DB link from BAcpt to Aprod and planned to use "Import from Database" option.
Option 1: By selecting "Schema" -> "Data Only", Import content type =" Import all objects", I am able to refresh BAcpt's tables with AProd's data, however, I can't refresh Sequences, especially the last_number of the sequences.
Option 2: By selecting " Schema" -> "All", Import content type =" Import all objects", I am afraid this will overrite all the roles/privs of BAcpt, and I have to run scripts to recreate BAcpt's roles, and grant those roles to users again...
Is there any better solution for this request?
Thanks,

Thank you first.
I did drop and recreate on target DB using source DB's sequences. Extending the original question a bit, if the sequence doesn't exist on target, I guess Option 1 won't bring over the new sequence/procedures from source DB either, correct?
Also for Option 1, It seems the Index also be updated........... Any document I can refer for details? I thought after import data, I need to "rebuild Index online" ... will it still be true ?
Thank you for any answers:-)

Oracle 10g - SCHEMA Export Import

Hi
I have a query - Whenever there are some changes in Database schema say for eg, New Columns are added, Some New Sequences are created and sundry other changes for an application release - What is the best way to take backup of the DDL so that I can bring the database / it's objects to the same position as they were in before the release?
Regards
Kapil

You can take export of the schema. Its not required any downtime.
Also, you take the cold backup and restore it to other server.
Clone the database by RMAN duplication and restore it to other server before making the changes.

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

Export/Import in Oracle8i to Oracle10g

Hi,
We have an Oracle8i Enterprise Edition Release 8.1.6.0.0(32 Bit) running on AIX4.3.3,we are planning to upgrade/migrate it to[b] Oracle10g running on AIX5.3.If i do an export from oracle8i whether i can import it in Oracle 10g without any issues.
Regards,
Cherry

Dear All,
Thanks for your efforts.
I have solved this problem and running the db in windows 2000 server without any problem.
Solution:
A tablespace should be created in the same name, size as in the solaris server. we cant transfer a tablespace created by solaris to windows. Before importing the data we need to create a tablespace and assign to the user (empuser).
here is the method that works for me.
1.GENERAL STEPS TO FOLLOW:
WINDOWS 2000 Server:
Install Oracle 9i release 1 (9.0.1.1.1) in windows 2000 server.
Create a database with following parameters;
1. Select 'General Database'
2. Global Database Name: EMP
3. SID: EMP
4. All default Options and click finish to create and start the oracle instance.
5. Login to SQL-PLUS (username: scott, Password: tiger, Hoststring: <empty>)
6. Connect as sys/change_on_install as sysdba;
7. CREATE TABLESPACE empdeploy DATAFILE 'C:\oracle\oradata\EMP\emp_data_new.dbf' SIZE 1000m AUTOEXTEND ON NEXT 100m MAXSIZE 2048m EXTENT MANAGEMENT LOCAL;
8. CREATE USER empuser IDENTIFIED BY emppass DEFAULT TABLESPACE EMPDEPLOY TEMPORARY TABLESPACE TEMP;
9. GRANT DBA TO EMPUSER (Im not sure whether i given this command or not, dont use this unless u get error during import)
10. disconnect

http://www.adp-gmbh.ch/ora/sql/create_tablespace.html
SUN-SOLARIS 5.6 (SPARC):
It is running Oracle Enterprise edition 8.1.6.
Get the informations below,
INSTANCE NAME
SID
USER HAVING CONTROL TO THAT INSTANCE (like here it was EMPUSER)
TABLESPACES USED
TABLESPACE NAME
DATAFILE NAME and PATH
ORACLE VERSION
2.EXPORT/IMPORT PROCEDURE:
I) Exporting Database from SOLARIS SERVER:
option-1:
exp empuser/emppass
leave all default options
Select Entire database to export (option 1)
YOU SHOULD GET 'Export terminated successfully without warnings'. (Failure causes may be low disk space, ensure that u have enough disk space)
Option-2:
exp empuser/emppass
leave all default options
Enter the user name whose tables to be exported: EMPUSER
Enter the user name whose tables to be exported: <Enter-to-quit>
YOU SHOULD GET 'Export terminated successfully without warnings'.
Option-3:
exp TRIGGERS=y CONSTRAINTS=y GRANTS=y FILE=expdat.dmp
Username: EMPUSER as sysdba
Password: emppass
leave all default options
Select Entire database to export (option 1)
YOU SHOULD GET 'Export terminated successfully without warnings'.
Option-4 (99% wont Work, RISKY):
EXPORT THE TRANSPORTABLE TABLE SPACE (This is different from exporting tables/data, so if all the above fails then export the Transportable table space and import into windows probably it will fail due to platform issue and CHARACTER SET Conversion)
Now import the expdat.dmp file again and see.
Change the required TABLESPACES READ ONLY.
exp TRANSPORT_TABLESPACE=y TABLESPACES=PMTDEPLOY TRIGGERS=y CONSTRAINTS=y GRANTS=y FILE=expdat.dmp
Username: EMPUSER as sysdba
Password: emppass
YOU SHOULD GET 'Export terminated successfully without warnings'.
Now Again Change the TABLESPACES to READ WRITE. (If you forgot this production server cant able to write to the database, the database will be left in read-only mode.)
$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
II) TRANSFERRING EXPORTED DATA FROM SOLARIS TO WINDOWS 2000 Server.
Now from windows system,
Open command prompt.
connect to SOLARIS SERVER USING FTP.
( cd /user1/home/oracle)change to the Path where you have exported the expdat.dmp file.
set the transfer mode to binary (dont use the default ASCII Transfer Mode)
get expdat.dmp
close
quit
Now the database was successfully exported from solaris and transferred to Windows 2000 server.
$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
III) Importing the Database in Windows 2000 server:
Open a Command prompt,
imp FULL=y IGNORE=n
Enter User Name : empuser
Password : emppass
You should get the same messages what you got during export, with out any other warnings or big messages running in the screen.
After completion you will get,
'Import terminated successfully without warnings'.
+++++++++Now Login thru SQLPLUS using username: empuser, password: emppass++++++++++
#the following query should return the total number of tables (142 here), this should be same as what you get in solaris. If you get 'no rows selected' then the import was failed, may be take a look at creating tablespaces, or around tablespaces)
select * from tab;
142 rows selected.
A kind request:
if you got your problem solved, please update the forum / usergroup and write how you solved the problem. this might be helpful for others who may face the same trouble. for me also there was some old postings that having similar problem. but they haven't given the solution. after their problem solved just left this forums.

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

Function-based spatial indexes

hello,
I'm using a function-based spatial index, which I've set up in a way similar to Oracle's examples in the Spatial documentation. Here's the basic idea:
create table places (
place_id not null
primary key,
latitude number,
longitude number
-- This function is used to create an MDSYS.SDO_GEOMETRY object
-- as part of the Oracle Spatial indexing of the latitude and
-- longitude.
create or replace function get_long_lat_pt(
longitude in number,
latitude in number)
return MDSYS.SDO_GEOMETRY deterministic
is
begin
if latitude is null or longitude is null
then
return null;
else
return mdsys.sdo_geometry(2001, 8307,
mdsys.sdo_point_type(longitude, latitude, NULL), NULL, NULL);
end if;
end;
show errors
INSERT INTO USER_SDO_GEOM_METADATA
VALUES ('PLACES', 'schema_name.GET_LONG_LAT_PT(LONGITUDE,LATITUDE)',
MDSYS.SDO_DIM_ARRAY(
MDSYS.SDO_DIM_ELEMENT('Longitude', -180, 180, 0.00000005),
MDSYS.SDO_DIM_ELEMENT('Latitude', -90, 90, 0.00000005)),
8307
-- Create Oracle Spatial function-based index
CREATE INDEX places_long_lat_idx ON places(get_long_lat_pt(longitude, latitude))
INDEXTYPE IS mdsys.spatial_index PARAMETERS('layer_gtype="POINT"');
All of this works just fine. But then I try to do a nearest neighbor calculation:
select /*+ INDEX(places places_long_lat_idx) */ place_id
FROM places WHERE
SDO_NN(
get_long_lat_pt(longitude,latitude), -- table values
get_long_lat_pt(-71.1482, 42.3367), -- an arbitrary point
'sdo_num_res=2') = 'TRUE'
and I get this:
ERROR at line 1:
ORA-13249: SDO_NN cannot be evaluated without using index
ORA-06512: at "MDSYS.MD", line 1723
ORA-06512: at "MDSYS.MDERR", line 17
ORA-06512: at "MDSYS.PRVT_IDX", line 27
It's as though Oracle isn't using the function-based index inside my SDO_NN call, even with a INDEX hint. I am stumped.
Just for kicks I tried to do a query using SDO_FILTER instead. I get:
ERROR at line 1:
ORA-13268: error obtaining dimension from USER_SDO_GEOM_METADATA
ORA-06512: at "MDSYS.MD", line 1723
ORA-06512: at "MDSYS.MDERR", line 8
ORA-06512: at "MDSYS.SDO_3GL", line 365
I am using Oracle 9.0.1.0.0, and I set QUERY_REWRITE_ENABLED=TRUE and QUERY_REWRITE_INTEGRITY=TRUSTED as noted in the Spatial documentation.
Any clues?
Thanks,
Greg

Greg,
The only times I have seen this error is when the
two parameters you mention are not set properly for the session.
I have a feeling that the parameters (QUERY_REWRITE_ENABLED,
and QUERY_REWRITE_INTEGRITY) are not getting the right values.
Can you verify this by doing a
show parameter QUERY_REWRITE_INTEGRITY
and
show parameter QUERY_REWRITE_ENABLED
from the session from where you are trying to execute
the Spatial operator.
Or you can try setting them for the session by
alter session set parameter=value
to see if it makes a difference.
thanks

Hello:
The Oracle Data Pump utility is now the preferred tool to use to import and export data and metadata from an Oracle database. Oracle Data Pump provides capabilities that far exceed those provided by the older imp/exp programs. Further, in addition to command line invocation of the tool, Oracle Data Pump has a set of pl/sql APIs (DBMS_DATAPUMP) that will let you do import and exports from pl/sql. You can therefore easily set up an APEX page that will accept a bunch of parameters and execute the appropriate procedures within DBMS_DATAPUMP to do the export/import.
