Oracle 9i 10g slow spatial query

I have been using the following spatial query in oracle 9i to assign jurisdictions to spatial points.
SELECT /*+ordered*/ L.TCH_X_COORD, L.TCH_Y_COORD, T.NAME
FROM tis.tis_coordinates_hold_on L,
geospatial.mdt_admin_districts T
WHERE SDO_RELATE(T.GEOMETRY,
MDSYS.SDO_GEOMETRY(2001,41079,MDSYS.SDO_POINT_TYPE(tch_x_coord,tch_y_coord,NULL),
NULL,NULL),'mask=ANYINTERACT querytype=WINDOW') = 'TRUE'
AND tch_assigned_base_rte='M00001N'
By using the ordered hint I was able to double the retrieval rate. My problem is this: We are now migrating to oracle 10g, and the use of the ordered returns no rows (different incorrect results). If I remove the + ordered the results are correct, but I no longer get the increased speed of retrieval. Has anyone run into this problem, and can you suggest a way that I could speed up this query. As it stands now it takes more than 1/2 sec for each record retrieved, and I have millions of records !! Thanks.

We're using 10.2.4.0 I believe I have found the reason the queries were different. When I dropped the spatial index and re-created it, the query returned the same rows as 9i. However, I still have an issue with the speed. 10g appears to be about 1/3 as fast as 9i was. It doesn't seem to make any difference whether I put in the +ordered or not. Our dba says just based on cpu and processing speed the server that has 10g should be significantly faster. Any comments? Thanks.

Slow spatial query in oracle 11.2.0.3 [WAS 10.2.0.4 to 11.2.0.1 upgrade = SLOW sdo_geometry return]

Hi,
I've found a discussion ended last year.
I've Oracle 11.2.0.3 with the same problem: some query are very slow (in the Excecution plan I've found "PX COORDINATOR")
Others installation of Oracle 11.2.0.3 haven't same problem: in the excecution plan found "DOMAIN INDEX".
I 've solved using statement "ALTER TABLE table_name NOPARALLEL;" which disable parallel feature in the table
Can anyone tell me if it's a good (bad) solution ? thank you
Bye

Gabriele,
As indicated in the original post - the following work-around might work for you for bug 9743250. What this does is essentially force the optimizer to ALWAYS use the spatial index. That is usually good - unless the query is actually more efficient not using the index, such as when it is much cheaper to just to a FTS. Anyhow this is what you can do from 11.2.0.1 to 11.2.0.3 - fixed in 11.2.0.4 and 12.1.0.1:
connect /as sysdba
alter session set current_schema=MDSYS;
DISASSOCIATE STATISTICS FROM INDEXTYPES spatial_index FORCE
DISASSOCIATE STATISTICS FROM PACKAGES sdo_3gl FORCE;
DISASSOCIATE STATISTICS FROM PACKAGES prvt_idx FORCE;

Spatial query w/ logical operators in a subquery on Linux using Oracle 10g

Hello...
I'm being given XML that I need to parse and create SQL from it. Below my signature is the SQL that I generate (its a simple example) and can be more elaborate due to the logical operators (AND and OR) given in the XML.
The problem that we're seeing is performance-based: when one of the logical operator queries is Spatial-based, like below. Running it in JDBC, the query never returns.
The spatial query just by itself returns ~300 rows (takes approximately 0.2 seconds). The "PERCENTAGE" query by itself returns about ~40000 rows (takes approximately ~.8 seconds).
If we run the query below with 2 non-spatial subqueries, the result returns and performance is very acceptable (~ 0.9 seconds)-- the result set is about 80000 rows.
Thanks,
Jim

There is a spatial forum. You will likely have a far better experience there.

SQL slow after upgrading to Oracle Database 10g Enterprise Edition Release

Hi all:
We have recently upgraded our database from Oracle9i Enterprise Edition Release 9.2.0.6.0 to Oracle Database 10g Enterprise Edition Release 10.2.0.1.0
After that we found that our some sql getting very slow
for example query with 9i showing result in 4 seconds while in 10g showing result in 28 seconds.

I would say ..gather stats on 9i/10gfor the required table and indexes , then post the expalin plan.

Frm-40505:ORACLE error: unable to perform query in oracle forms 10g

Hi,
I get error frm-40505:ORACLE error: unable to perform query on oracle form in 10g environment, but the same form works properly in 6i.
Please let me know what do i need to do to correct this problem.
Regards,
Priya

Hi everyone,
I have block created on view V_LE_USID_1L (which gives the error frm-40505) . We don't need any updation on this block, so the property 'updateallowed' is set to 'NO'.
To fix this error I modified 'Keymode' property, set it to 'updatable' from 'automatic'. This change solved the problem with frm-40505 but it leads one more problem.
The datablock v_le_usid_1l allows user to enter the text (i.e. updated the field), when the data is saved, no message is shown. When the data is refreshed on the screen, the change done previously on the block will not be seen (this is because the block updateallowed is set to NO), how do we stop the fields of the block being editable?
We don't want to go ahead with this solution as, we might find several similar screens nad its diff to modify each one of them individually. When they work properly in 6i, what it doesn't in 10g? does it require any registry setting?
Regards,
Priya

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

Fast query in Oracle 10 but slow in Oracle 11

Hello all,
We have a query that is running smooth in Oracle 10g. It takes less then a second. We have setup a second server and used export/import to create the same database on 11g. On this 11g database the query takes a lot of time (like 8s or more).
Below are the details. Maybe somebody can point us to the reason why this happens.
We are talking about this statement :

I still find that my Oracle 10 DB is a tad faster.
Comparing the plans shows that my Oracle 10 DB does less physical reads. I think I will get the same speed if I can find a way to change that behaviour on my Oracle 11 DB or can find the reason why it does that.

select GEOMETRY_1
from table_a
where
ID = 970;
If I use sql plus I have this result
SDO_GEOMETRY(3001, NULL, NULL, SDO_ELEM_INFO_ARRAY(1, 0, 6000, 4, 1, 1), SDO_ORDINATE_ARRAY(1, -0, -
0, 580094, 4998494, -1))
but blank page when I use php sentence.
I use PHP Version 4.4.0
modules load are:

Now there isn't any problems: you and this link (Re: PHP and spatial data and Adamo Bozzetti helped me
I have used SDO_UTIL.GETVERTICES
my complete php script is:
$conn = @OCILogon("xxxxxx", "xxxxx", "xxxxx") or die
( "Non riesco a connettermi al server $host ");
$query = "select

and c.codice_via = TABLE_A.id_via
$istruzione = @OCIParse($conn, $query);
@OCIExecute($istruzione);
$nrows = @OCIFetchInto($istruzione, $results);

10G bug: Simple query terminate oracle session in 10g

The following query fails because it terminates the connection to the oracle database. This only occurs in 10g and Oracle XE. Below that query is the structure of the table and sql statements to populate the table.
I got this from a friend who tried to use 10g, but had to upgrade to Oracle 9 :-) I tested it with Oracle XE. Same problem with 10g and XE. We both use fully patched Windows XP professional.

Query execution taking longer time in Oracle form 10g !!

Hi,
I'm generating a report through Oracle form ( forms 10g) and its taking 3-4 hours to finish. But when I run the same report query in (Oracle 11g) database, it gets executed in less than 40 mins.
The form takes only from and to date as input.
I tried hardcoring the date in the Oracle Form and then the report takes only 40 mins to generate.
I tried various approaches like changing the datatypes of form variable and correspondingly changing the query, but met with no success.
When the report in run through the form , we can see the query getting run in backend for nearly 3 hrs !!! tats really confusing !!
Please let me know, if anybody got any idea on this problem??

Hi,
Even I am facing the same problem above. I am trying to fetch results from a cursor which has subquery running over the db link and placing the results set in a csv file using client_io package. When I run the cursor directly from database (11G), it takes not more than 3-4 min to get the results back. But when I run the same cursor via oracle forms 10G, the query in local database keep on waiting for hours to get results from remote database with "SQL*Net message from dblink". Session on local database remains in active status with state as "Waiting" while the session on remote database goes inactive with state as waiting for event "SQL*Net message from client"
This is confusing me since the same query when ran directly from backend fetches results soon.
Please let me know if anyone can help here
Thanks
Garima

Slow Problems with Oracle Forms 10g and Oracle Database 11g

Hi, I wonder if there is a compatibility problem between Version 10.1.2.0.2 32 Oracle Forms and Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production. This is because my application runs correctly on a version of Oracle Database 10g, and when we migrated the database to an Oracle Database 11g, slowness problems came out.
Thanks.

We have the same issue happening with our custom forms and with some of the standard forms in EBSO. So far we have found that the form invoking a view causes ridiculous slowness in opening the form (40 mins). Using a table access has shortened the open time significantly. At this time Oracle DBAs at OOD have no clear idea why it is happening.
we are on 11.1 database with 11.5 EBSO

Oracle spatial query SDO_LRS with php

Hello, I have this problem,
I use php for read data from oracle table.
I know I can't show on web page the result of SDO_ORDINATE_ARRAY
Christopher Jones has written that I must use SDO_UTIL.GETVERTICES like as
select
t.X,
t.Y
from table_a, TABLE(SDO_UTIL.GETVERTICES(table_a.GEOMETRY_1)) t
where
id_num = 970;
But now I must read a projection point ordinate of a point with respect to a geometric segment
and the same problem come back.
esemple of spatial query that I use:
SELECT
SDO_LRS.PROJECT_PT(geometry,
SDO_GEOMETRY(3301, NULL, NULL, SDO_ELEM_INFO_ARRAY(1, 1, 1), SDO_ORDINATE_ARRAY(580094.69, 4998493.68, NULL)) )
FROM
TABLE_B
WHERE
ID_CODE = 970;
If I use sql plus I have this result
SDO_LRS.PROJECT_PT(GEOMETRY,SD(SDO_GTYPE, SDO_SRID, SDO_POINT(X, Y, Z), SDO_ELEM
SDO_GEOMETRY(3301, NULL, NULL, SDO_ELEM_INFO_ARRAY(1, 1, 1), SDO_ORDINATE_ARRAY(
580093,325, 4998497,57, 45,2254405))
Which is exacly the query for extract these coordinates?
Someone can help me?
My English is very bad please reply easy.
Thanks for all!
Angelo

Hello thanks for all to everyboby.
I put the same question on Forum /Category/Database/Spatial and I have received this reply
from Brian Camire, this query worked well.
SELECT
T.X,
T.Y
FROM
TABLE
SELECT
SDO_UTIL.GETVERTICES
SDO_LRS.PROJECT_PT
GEOMETRY,
SDO_GEOMETRY
3301,
NULL,
NULL,
SDO_ELEM_INFO_ARRAY(1, 1, 1),
SDO_ORDINATE_ARRAY(580093.859, 4998493.5, NULL)
FROM
TABLE_B
WHERE
ID_CODE = 970
) T;
Best regards

Oracle 8i giving slow response when running sql query

hi ,
i am using oracle 8i server ;
and sql query giving slow response before some days;
so which parameter need to increase
DB_BLOCK_BFFERS OR SHARE_POOL_SIZE
CURRENT SETING IS
DB_BLOCK_BUFFER=256000;
SHARE POOLSIZE=300M;
pls advice to me
thanks

No parameters need to be increased. Tuning is not done but making arbitrary changes to values and hoping that good things will happen by accident.
The thing you really should be worrying about is your antique database and likely its impact on your skill set unless you are one year away from retirement.
Where's the actual version number?
Where's the DDL?
Where's the DML?
Where's the Explain Plan?

Spatial query w/ logical operators in a subquery on Linux using Oracle 1

Hello...
I'm being given XML that I need to parse and create SQL from it. Below my signature is the SQL that I generate (its a simple example) and can be more elaborate due to the logical operators (AND and OR) given in the XML.
The problem that we're seeing is performance-based: when one of the logical operator queries is Spatial-based, like below. Running it in JDBC, the query never returns.
The spatial query just by itself returns ~300 rows (takes approximately 0.2 seconds). The "PERCENTAGE" query by itself returns about ~40000 rows (takes approximately ~.8 seconds).
If we run the query below with 2 non-spatial subqueries, the result returns and performance is very acceptable (~ 0.9 seconds)-- the result set is about 80000 rows.
Thanks,
Jim
=========================
SELECT
COLUMN_WE_WANT , RESULTS
FROM
TABLE_A
WHERE
COLUMN_WE_WANT IN
SELECT
COLUMN_WE_WANT
FROM
TABLE_A
WHERE
SDO_OVERLAPBDYINTERSECT(TABLE_A.MY_SPATIAL_COLUMN,
SDO_GEOMETRY(2003,
4326,
null,
SDO_elem_info_array( 1 , 3 , 1 ),
SDO_ORDINATE_ARRAY( lng_1,lat_1 , lng_2,lat_2 , lng_3,lat_3 , lng_4,lat_4 , lng_1,lat_1 )
) = 'TRUE'
OR
COLUMN_WE_WANT IN
SELECT
COLUMN_WE_WANT
FROM
TABLE_B
WHERE
SOME_PERCENTAGE_RATE_COLUMN < 90
)

Its difficult to comment without seeing the execution plan. You should trace this query to get a better idea of exactly what's happening.
Depending on the complexity of the logical operators, I would look at doing this using set operations. So for an OR you might have...
SELECT COLUMN_WE_WANT, RESULTS
FROM TABLE_A
WHERE COLUMN_WE_WANT IN (
     SELECT COLUMN_WE_WANT
     FROM TABLE_A
     WHERE SDO_OVERLAPBDYINTERSECT(TABLE_A.MY_SPATIAL_COLUMN,SDO_GEOMETRY(2003,4326,
     NULL, SDO_elem_info_array( 1 , 3 , 1 ),
     SDO_ORDINATE_ARRAY( lng_1,lat_1 , lng_2,lat_2 , lng_3,lat_3 , lng_4,lat_4 , lng_1,lat_1 ) )) = 'TRUE'
UNION
     SELECT COLUMN_WE_WANT
     FROM TABLE_B
     WHERE SOME_PERCENTAGE_RATE_COLUMN < 90)For an AND, you would use INTERSECT.
Edited by: Reggie to remove the extra INTERSECT

Oracle Spatial Query from SQLPLUS deteriorates in performance

Hi,
I am running an sql-procedure, which does spatial queries. When I run this procedure (from SQLPLUS) for the first time it takes around 45 sec to complete, but when I run the same procedure for the second time it takes 65 seconds and the performance keeps on decreasing. But if I open a new SQLPLUS session it takes 45 secs and it also starts deteriorating subsequently. This strange behaviour is only for spatial queries, if I don't have spatial queries in my procedure then its fine.
I found this behaviour for any type of spatial query.
Is there something which can be done for improving it ? I found a lot of information on improving performance of a query, but my problem is to maintain the same performance of the same query in the same session.
Thanks,
Rishi

Hi,
Could you provide version information?
Also, could you try monitoring memory as the procedure is running an see
if memory climbs more each time the procedure is run?
Thanks
