• query takes too long

  Hello
  
  The following query takes too long (more than 30 minutes), work with 11g.
  The table has three columns RID, ida, geometry and index has been created on all of the columns.
  The table has about 5,40,000 documents of point geometries.
  
  Please help me with your suggestions. I want to select the geometry in double point where ida = STRING.
  
  
  SQL > select a.rid, b.rid from totalrecords, totalrecords b where a.ida = 'CORD' and b.idat = 'CORD' and
  sdo_equal (a.geometry, b.geometry) = 'TRUE' and a.rid! = b.rid order of 1,2;

  Hello

  Just glad it helped, don't forget to award points ;-).

  The SDO_JOIN will use the spatial index for a spatial comparison.
  First of all, it will use the index to check which geometries MBR interact, it is the primary filter: http://docs.oracle.com/cd/B28359_01/appdev.111/b28400/sdo_intro.htm#g1000087

  Secondly, you should apply a space MASK, pair of geometries that comes out of the primary filter is then compared according to the MASK, MASK for example = EQUAL, will check these pair of geoms are equal.

  Now, because you have points, the members are the points themselves, so that if their MBR interact, points to interact, which means they are equal.
  This means that the result of the SDO_JOIN points, in this case even a self-join, will give you all the points that are equal.

  But as points are also equal in their car, the join join reflexive sdo, will give you: a = b & one = one but also a b.
  To this effect, you set the a.rowid< b.rowid,="" to="" avoid="" a="a" but="" also="" b="">

  I hope this explains it a little, again read and read great literature (early!), will have a better understanding.

  Good luck

• What query takes too long

  How can you know which application takes too long to run in a database? and most of the resources consumption?

• Query takes too long, but the cost is low

  Hi guys,.
  
  I run a query on two databases that were created in the same way and have the same data.
  
  On one, the cost is almost 1 million, and it runs in the space of a few seconds
  On the other hand, the cost is 40,000, and it does not end execution
  
  I looked at the plan to explain it and there is no Cartesian merge on the second query join, but it takes so long. What can I do to study this?
  
  Thank you

  The sqlxtplan provides comprehensive information on the query that was executed, or running, depending on the mode you choose. It has all the information of dbms_xplan plus much more. for example all the table definitions used in the query, filters of predicate query, plans for execution, his stats of all tables, indexes, etc... used in the query.
  I find the way the fastest to get an overview of how the optimizer made its decision. If it is running run mode, it, rather than using the id of sql or hash, it also gives a 10053 trace.

• Query takes too long to run after clone

  Hi all
  
  We have a query that works well in our development environment and take about 15 seconds to run the query. When we run the same query with the same parameters in a recently cloned instance, the query takes 1200 dry run.
  Please help us on this issue.

  Thanks for any response.
  We have solved the problem by using indicators of index.

• create table query takes too long...

  Hello experts...
  
  I take the backup of table A, which consist of 135 million records...
  
  Why use query below...
  
  create the table tableA_bkup in select * from tableA;
  
  It takes more time... always running...
  
  is there another way to quickly query...
  
  Thanks in advance...

  ECT is one of the fastest ways to do such a thing.

  Do you remember the duplicate data. This means that if your table contains 50 GB of data, then it will have to copy these 50 GB of data.

  Another way may be to use EXPDP to create a backup of the data of the table dump file. However I don't know if there is a difference in performance.
  The two versions might benefit from parallel execution.

• Statement Update takes too long to run

  Hi all
  
  I am trying to run this update statement. But its takes too long to run.
  

      UPDATE ops_forecast_extract b SET position_id = (SELECT a.row_id
          FROM s_postn a
          WHERE UPPER(a.desc_text) = UPPER(TRIM(B.POSITION_NAME)))

  SELECT count(*)
          FROM s_postn a, ops_forecast_extract b

  What could be the reason for the update statement to run so long?

  You did not say what means "too long", but a simple and good reason might be that the scalar subquery on "s_postn" using a full table for each run scan. Potentially this subquery is executed for each row of the table "ops_forecast_extract" that satisfies your filter predicates. 'Potentially' due to "filter/subquery optimization" cunning of the Oracle execution engine that tries to cache results of already executed of instances of subquery. Given that the in-memory hash table that contains these cached results is limited in size, the optimization algorithm depends on the sort order of data and could suffer collisions of hash that it is unpredictable, how this optimization works in your particular case.

  You can view the execution plan, it should at least tell you how Oracle will run the scalar subquery (that tell you nothing about this "filter/subquery optimization" feature).

  Follow the generic guidelines how to generate a useful plan explain output and how to post here:

  Could please post a correctly formatted explain you plan output using DBMS_XPLAN. SCREEN, including the 'Predicate information' section below the plan to provide more details about your statement. Please use the noformat} [{noformat} code {noformat}] {noformat} before tag and {noformat} [{noformat} / code {noformat}] {noformat} tag or after the noformat} {{noformat} code {noformat}} {noformat} tag before and after to improve the readability of the outing:

  In SQL * more:

  SET LINESIZE 130
  
  EXPLAIN PLAN FOR ;
  
  SELECT * FROM TABLE(DBMS_XPLAN.DISPLAY);
  

  Note that the DBMS_XPLAN package. DISPLAY is only available from 9i on.

  In 9i and above, if "Predicate information" section is missing from the DBMS_XPLAN. Output display, but you get the message "Plan table is old version" instead, you must recreate your plan table using the script server '$ORACLE_HOME/rdbms/admin/utlxplan.sql '.

  In previous versions, you can run the following in SQL * Plus (on the server) instead:

  @?/rdbms/admin/utlxpls
  

  A different approach in SQL * more:

  SET AUTOTRACE ON EXPLAIN
  
  ;
  

  also displays the execution plan.

  In order to get a better understanding where your statement passes the time, you might want to turn on SQL tracing as described here:

  When your query takes too long...

  and after the "tkprof' out here, too.

• Inserting data in the remote table takes too long

  That takes a lot of time, then don't you have an idea how can we send the data fast

  Buy more band witdth?

  No, honestly. As you can see, the quality of my answers match the quality of your question.

  You must locate the bottleneck, where is - this "too much" time has passed.

  Is it
  collection of data on the local side?
  net send?
  Actual insertion on remote site?
  Maybe you have a condition on the remote site, which causes the data sent to the remote side to local?

  Impossible to give advice without knowing anything about what is happening.

• LaserJetPro HP 1102w impression takes too long

  Hello

  I installed HP 1102w on my laptop using the driver from the CD. Printing is configured using USB and ePrint is disabled.

  Printing takes very long (18 s). When I send a print job (even test page), I don't see that it appears in the printer job window liquid. However until I see that some data has been sent to the printer (for example 4 KB / 146kb) time is about 9 seconds. To start sending data up to what the page is printed is another second 8-9 so time total is Reiver 18 seconds in the best of cases.

  My laptop is:

  Windows Visa Business, 3 GB of RAM, Dual-Core clocked at 1.6 GHZ, SSD drive 120 GB.

  I tried to install the XPS (planned it will be faster) driver for this printer however failed to install with the 0x070c error code.

  Please have a tip how to print faster (reduce the time of 8 seconds until that data is sent to the printer)

  Thank you

  Miro.

  Hi @MKLI ,

  I see by your post that the printer takes too long to print in a USB connection. I would like to help you today.

  What kind of documents you print? (PDF, Txt)

  Have what applications you tried?

  Try a different file or application to see if you have the same results.

  Try and print a self-test on the printer hardware to see if it is a hardware or software problem.

  Printing a Configuration Page. Select the method two.

  Make sure the printer is connected directly to a wall outlet and the USB cable is connected directly to the computer. The USB cable should not be more then 6 feet. Try a different USB port on the laptop. Some ports are higher power then others. You may need to try another USB cable to see if that causes this problem.

  Check the power on the computer to see if that is causing the problem.

  How to make in the Windows Device Manager?

  Go to Device Manager, under Bus for each made USB root hub controllers right click and left click on properties, for the management of the power supply remove the check box for "allow the computer to turn off this device to save energy. It allows the computer to restrict or cut off the power for this unit.

  Restart the spooler to print on the laptop.

  Click Start (), type services.msc in the Search box and press ENTER.

  Find the service named print spooler, right click and select Properties. Click on stop and then click Start.
