• 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

• Data dictionary query takes too long.

  Hello
  I'm using ORACLE DATABASE 11 g.
  
  The following query takes too long to run and not give the result. As I've tried a few tricks SQL Oracle but it forces developed.
  

  SELECT 
  distinct B.TABLE_NAME, 'Y' 
    FROM USER_IND_PARTITIONS A, USER_INDEXES B, USER_IND_SUBPARTITIONS C
   WHERE A.INDEX_NAME = B.INDEX_NAME
     AND A.PARTITION_NAME = C.PARTITION_NAME
     AND C.STATUS = 'UNUSABLE'
      OR A.STATUS = 'UNUSABLE'
      OR B.STATUS = 'INVALID';

  Please guide me what to do? to run this query in a fast paced mode...
  
  
  Thanks in advance...

  Your query is incorrect. It returns all tables if A.STATUS = "UNUSABLE" or B.STATUS = "INVALID". Most likely, you meant:

  SELECT
  distinct B.TABLE_NAME, 'Y'
    FROM USER_IND_PARTITIONS A, USER_INDEXES B, USER_IND_SUBPARTITIONS C
   WHERE A.INDEX_NAME = B.INDEX_NAME
     AND A.PARTITION_NAME = C.PARTITION_NAME
     AND (C.STATUS = 'UNUSABLE'
      OR A.STATUS = 'UNUSABLE'
      OR B.STATUS = 'INVALID');
  

  But the above will return sous-partitionnee tables not valid/no usable index. He ain't no non-sous-partitioned tables partitioned index/index not valid/not usable with same partitions in the form of tables not partitioned with valid/no unusable indexes. If you want to get any table with indexes not valid/not usable, you outer join that's going to hurt even more performance. I suggest you use the UNION:

  SELECT  DISTINCT TABLE_NAME,
                   'Y'
    FROM  (
            SELECT INDEX_NAME,'Y' FROM USER_INDEXES WHERE STATUS = 'INVALID'
           UNION ALL
            SELECT INDEX_NAME,'Y' FROM USER_IND_PARTITIONS WHERE STATUS = 'UNUSABLE'
           UNION ALL
            SELECT INDEX_NAME,'Y' FROM USER_IND_SUBPARTITIONS WHERE STATUS = 'UNUSABLE'
          ) A,
          USER_INDEXES B
    WHERE A.INDEX_NAME = B.INDEX_NAME
  /

  The query you posted is obviously fake.

• 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 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.
  
  Thank you

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

  Thanks for the update!

• 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.

• Measure the power takes too long

  Hi all

  I use Agilent 8163 b with 2 slots: 81619A (2 heads) and 81618 a. (1 head) for power measurements.  I have set up my measurement with driver Setup for the time of Agilent vi to the average duration of 5 seconds.  However, it took total more than 20 seconds to complete the measure of 3 channels using Agilent 816 x reading PMW Value.vi (this VI calls a DLL hp816x_32).

  My question is that can I get this measure nearly 5 s with a parallel read 3 channels at the same time?  I.e. the reentrant hp816x_32 DLL?

  I tried to have a wiring in parallel of 816 x reading PMW Value.vi to test this, but still get a time of 21 seconds measures.  Anyone have a suggestion to improve this?

  Thank you

  Bryan

  I'm not familiar with this specific material. But how much time does it take if you only measure a single channel? If it also takes 20 seconds I guess that the vi is to configure the device whenever it works (it is a painful overload). You can go down to the Basic by using the READ and FETCH commands? for an optimal speed on similar devices (I don't remember too much syntax).

• Audio mixing for the preview takes too long

  Dear all people on the forum.

  I had a problem with the video preview in after effects CC, for awhile. I find the problem that he had just "Audio Mixer to Preview". This process is very long compared to other processes during the preview rendering. When I disable the audio preview on the Preview Panel, the preview began almost instantly after the preview has been triggered. Audios are easier to deal with videos, it's taking boring too long. Also, I noticed that the more layers, the graphics and audio files are added to the file, the longer it takes for previewing start. Help, please!

  There is probably nothing wrong. EI audio capabilities are severely limited and it doesn't all in time real mixture worth mentioning. It can only play a limited number of audio tracks in real time, and those who must match the settings of your audio driver, since that's what it is based on. All files that is not conform to the specifications as well as incompatible driver audio settings force resampling. Similarly, compressed as MP3 files, it will be decoded fully first and then mixed. Don't say things could not be better, but you should get used to. If you provide system information and more details about your project it may be possible to certain optimization...

• How can I stop firefox 13 takes too long to load pages

  I used to regularly visit http://kol.coldfront.net/thekolwiki/index.php/Special:RecentChanges

  I can't stand the ads, well, then I added all sites ad to etc/hosts pointing to localhost.

  until recently, the pages loaded fine, the dns lookup has failed in a transparent manner.

  I've just updated to firefox 13.

  now, every time the page loads I get "connecting to pagead2.googlesyndication.com"for about 15 seconds.

  Since everyone loses interest in a page after 10 seconds, what makes visit to this site a bit frustrating.

  any ideas how I can change this back to the pre-13 behavior?

  maybe try to use adblock more instead of the host file - https://addons.mozilla.org/firefox/addon/adblock-plus

• Save the JPEG, the process takes too long time, how to cut it short?

  Hi all

  I work 8 hours a day using Photoshop CS6 each time come to SAVE JPEG, it ask the quality and I have to select "highest quality 12", I go to the settings to reset, so that my files JPEG is always 12?

  Thank you

  Hi JimmyChelsea,

  Yes, reset default return Photoshop preferences and then open a jpeg file save the image with a high quality 12 and next time when you save any other jpeg, it should show you the quality, worth 12.

  To re-create the Photoshop preferences files, start the application while pressing Ctrl + Alt + Shift (Windows) or command + Option + shift (Mac OS). Then, click Yes to the message, "Delete the Adobe Photoshop settings file?"

  Kind regards

• The publication takes too long

  I have developed an AIR application that is compatible with Flash Player. I can't make it work on my iPad, I already have the developer certificate. Publication settings are correct, but it's 1 hour I publish, it still shows 'Édition. '... ». Any idea? [B] is it really so long to publish .ipa? [/ B] My scene resolution is 1024 x 768. Size of FLA is 1.63 MB and external jpg, SWF and FLV files are 503 MB.

  Finally, I understood the problem. I have something like that in my project:

  var arrayName:Array = new Array();

  var num:uint = 0;

  arrayName.push (new Object());

  arrayName [num] .type1 = "string value";

  arrayName [num] .type2 = "string value";

  arrayName [num] .type3 = "string value";

  arrayName [num] .type4 = "string value";

  arrayName [num] .type5 = "string value";

  arrayName [num] .type6 = "string value";

  arrayName [num] .type7 = "string value";

  arrayName [num] .type8 = "string value";

  arrayName [num] .type9 = "string value";

  arrayName [num] .type10 = "string value";

  arrayName [num] .type11 = "string value";

  NUM ++;

  Similarly, I add objects 571 (total length of arrayName is 571). It's like the database as flash does not support the database directly. If I publish along with all data (571), he stops creating file, but if I reduce the amount of data to 5, it creates the file ipa...

  Also, I discovered that whenever flash publishes for ipa, initially it creates a file in Directory publishing "AOTBuildOutput # .tmp ' and a file ' air # .tmp '... If all goes well as it creates a file more "AOT # .tmp '. It removes the folder and then deletes the two files and creates the .ipa file... If you see the Flash progress bar but can't find these files/folder, it is hung. You should stop editing and which would indeed crash flash and try again. It is for those who are facing similar problems like me.

  Could @Adobe/Sanika, you please let me know how to sort?

• Select the query takes a long time to run the second time

  Hi all
  
  I have Oracle 11 GR 1 material in windows server 2008 R2.
  I have a few tables with 10 million documents. When I run the select query to the tables of first time, it gives me a result in 15 seconds, but if I run the script even twice in the same session, I get the result in 15 minutes to complete...
  
  Why it's happening? What can be the solution for this?

  What I know is that this feedback from cardinality generates more problems than improving the performance is, in fact, its main objective. But first look at which is was written in the link I posted above

  "Return of cardinality was introduced in the Oracle 11 g database 2. The purpose of this function is to automatically improve plans for queries that are executed repeatedly, _For that the optimizer does not estimate the cardinalities in the properly_ plan"

  If the cardinality feedback kiks in your case it is certainly because you do not have an exact statistics. Get the command the explain plans that I have shown you with the E-lines and A-lines (lines estimates and actual lines) and see where things are poorly estimated.

  If you want to disable the cardinality feedback then add the indicator according to your request

  /*+ opt_param('_optimizer_use_feedback','false') */

• 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.
