• 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
  /

  Try to use the following text:

• 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.
  
  Thank you

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

  Thanks for the update!

• 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
          WHERE UPPER(a.desc_text) = UPPER(TRIM(B.POSITION_NAME));

  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.

• My daughter Air2 IPad takes too long to save. It is connected to wifi, connected and the screen is locked.mAny advice?

  My daughter Air2 IPad takes too long to save. It is plugged in, connected to wifi and the screen is locked. Any tips?

  How long is too long? If it lasts for more than a few hours - and even that is too long in my humble OPINION - then something is wrong. Completely backup, because it will not terminate in any case if its been so long, forced to reboot the device and try again.

  To force the reboot your device, press and hold the two buttons of sleep/wake and home for at least ten seconds, until you see the Apple logo.

  This may not work either. The backup may be damaged and you will need to remove and start over. However, its easy starting point and it will not hurt anything. If the backup will not end, he has nothing to lose.

• Why it takes too long to open attachments of the e-mail account?

  It takes forever to download attachments from my mail account. I tried to do the following tasks explained on the vista forum: http://windowshelp.microsoft.com/Windows/en-US/help/6b046ae9-1434-4423-9303-400ff6fe686b1033.mspx#ESD, but none of the fixed work possible.

  After clicking on open on the box pop up asking if I want to open or save the attachment, it takes too long to download. The transfer window remains open to showing that he is ready to download, but rest in this window of bhox. I press cancel and try to open once again, if the chance that it opens this file, otherwise it takes forever forceing me to cancel. Very small files most of the time, usually between 50 KB should take seconds.

  I even tried to save the files, but once again the same process. The transfer case remains open but does not download.

  One of the ideas.

  Thanks in advance.

  Hello

  It is not easy to tell exactly what is happening, but it must be something with the e-mail account provider and their page. For me, this case is not a typical problem of Vista, but you can try to find the solution on Vista from Microsoft IT Pro forum.

  By the way: you have an alternative email by another provider address? Is it the same situation?
