• Insert - Performance problem

  Hi Experts,

  I am new to Oracle. Ask for your help to fix the performance of a query of insertion problem.

  I have an insert query that is go search for records of the partitioned table.

  Background: the user indicates that the query was running in 30 minutes to 10 G. The database is upgraded to 12 by one of my colleague. Now the query works continuously for hours, but no result. Check the settings and SGA is 9 GB, Windows - 4 GB. DB block size is 8192, DB Multiblock read file Count is 128. Overall target of PGA is 2457M.

  The parameters are given below

  Thanks in advance

  Firstly, thank you for posting the 10g implementation plan, which was one of the key things that we were missing.

  Second, you realize that you have completely different execution plans, so you can expect different behavior on each system.

  Your package of 10g has a total cost of 23 959 while your plan of 12 c has a cost of 95 373 which is almost 4 times more.  All things being equal, cost is supposed to relate directly to the time spent, so I expect the 12 c plan to take much more time to run.

  From what I can see the 10g plan begins with a scan of full table on DEALERS, and then a full scan on SCARF_VEHICLE_EXCLUSIONS table, and then a full scan on CBX_tlemsani_2000tje table, and then a full scan on CLAIM_FACTS table.  The first three of these analyses tables have a very low cost (2 each), while the last has a huge cost of 172K.  Yet once again, the first three scans produce very few lines in 10g, less than 1,000 lines each, while the last product table scan 454 K lines.

  It also looks that something has gone wrong in the 10g optimizer plan - maybe a bug, which I consider that Jonathan Lewis commented.  Despite the full table scan with a cost of 172 K, NESTED LOOPS it is part of the only has a cost of 23 949 or 24 K.  If the math is not in terms of 10g.  In other words, maybe it's not really optimal plan because 10g optimizer may have got its sums wrong and 12 c might make his right to the money.  But luckily this 'imperfect' 10g plan happens to run fairly fast for one reason or another.

  The plan of 12 starts with similar table scans but in a different order.  The main difference is that instead of a full table on CLAIM_FACTS scan, it did an analysis of index on CLAIM_FACTS_AK9 beach at the price of 95 366.  It is the only main component of the final total cost of 95 373.

  Suggestions for what to do?  It is difficult, because there is clearly an anomaly in the system of 10g to have produced the particular execution plan that he uses.  And there is other information that you have not provided - see later.

  You can try and force a scan of full table on CLAIM_FACTS by adding a suitable example suspicion "select / * + full (CF) * / cf.vehicle_chass_no...". "However, the tips are very difficult to use and does not, guarantee that you will get the desired end result.  So be careful.  For the essay on 12 c, it may be worth trying just to see what happens and what produces the execution plan looks like.  But I would not use such a simple, unique tip in a production system for a variety of reasons.  For testing only it might help to see if you can force the full table on CLAIM_FACTS scan as in 10g, and if the performance that results is the same.

  The two plans are parallel ones, which means that the query is broken down into separate, independent steps and several steps that are executed at the same time, i.e. several CPUS will be used, and there will be several readings of the disc at the same time.  (It is a mischaracterization of the works of parallel query how).  If 10g and 12 c systems do not have the SAME hardware configuration, then you would naturally expect different time elapsed to run the same parallel queries.  See the end of this answer for the additional information that you may provide.

  But I would be very suspicious of the hardware configuration of the two systems.  Maybe 10 g system has 16-core processors or more and 100's of discs in a matrix of big drives and maybe the 12 c system has only 4 cores of the processor and 4 disks.  That would explain a lot about why the 12 c takes hours to run when the 10 g takes only 30 minutes.

  Remember what I said in my last reply:

  "Without any contrary information I guess the filter conditions are very low, the optimizer believes he needs of most of the data in the table and that a table scan or even a limited index scan complete is the"best"way to run this SQL.  In other words, your query takes just time because your tables are big and your application has most of the data in these tables. "

  When dealing with very large tables and to do a full table parallel analysis on them, the most important factor is the amount of raw hardware, you throw the ball to her.  A system with twice the number of CPUS and twice the number of disks will run the same parallel query in half of the time, at least.  It could be that the main reason for the 12 c system is much slower than the system of 10g, rather than on the implementation plan itself.

  You may also provide us with the following information which would allow a better analysis:

  • Row counts in each tables referenced in the query, and if one of them are partitioned.
  • Hardware configurations for both systems - the 10g and the 12 a.  Number of processors, the model number and speed, physical memory, CPU of discs.
  • The discs are very important - 10g and 12 c have similar disk subsystems?  You use simple old records, or you have a San, or some sort of disk array?  Are the bays of identical drives in both systems?  How are they connected?  Fast Fibre Channel, or something else?  Maybe even network storage?
  • What is the size of the SGA in both systems?  of values for MEMORY_TARGET and SGA_TARGET.
  • The fact of the CLAIM_FACTS_AK9 index exist on the system of 10g.  I guess he does, but I would like that it confirmed to be safe.

• How to perform an addition of column values in an insert query that would insert in the 3rd column, and the values how to insert into another table.

  I have two tables (2) RESULT TAB (1)

  CREATE TABLE TAB

  (

  NUMBER OF SNO

  A NUMBER,

  B THE NUMBER.

  NUMBER OF THE SUM

  );

  CREATE AN ARRAY OF RESULT

  (

  NUMBER OF SNO

  NUMBER OF THE SUM

  )

  my doubt is:

  (1) I want to insert a table TAB, my question is how to insert a column to the SUM using the column A AND B... Here im adding two values of the column and store result in the AMOUNT column.

  SNO   A  B  SUM           

  1 100 150 250

  2 300 100 400

  I want to like this, it is possible with single insert query?

  
  

  (2) at the time of the insertion TAB of values that SNO, and the values of table TAB $ insert in the table of RESULTS... is it possible these two inserts at the same time?

  in fact, im using another this table.fro TAB and easy to understand I write like that, please solve this problem

  First, you post in the wrong forum as this one is only for Oracle's SQL developer tool. So you might ask your question in the general forum of SQL.

  Second, you might solve your problems with bind variable:

  Insert tab

  (sno, a, b, sum)

  values

  (: SNO,: A: B: A + B :))

  You should not use sum as column name because it is a reserved word.

  More you cannot insert into two different tables with a single SQL, but you can use PL/SQL to do this:

  Start

  insert into tab values (: SNO,: A: B: A + B :);)

  insert into result values (: SNO,: A + B :);)

  end;

  If you meet sno from a sequence, you could do something like this:

  Start

  insert into values tab (seq_sno.nextval,:,: B,: A +: B) return sno in: SNO.

  insert into result values (: SNO,: A + B :);)

  end;

  Hope that helps,

• Insert query syntax error

  Any recommendations?

  > Any recommendations?

  (1) enable debugging in order to visualize the generated actual query and post the SQL here
  (2) empty the form field. Are all of the form simple strings of values?
  

  (3) for the values inserted into a date/time column, you use cfqueryparam or CreateODBCDate, CreateODBCDateTime to convert the string to an object of good time. This ensures that the value is inserted properly

  Although I personally recommend to use cfqueryparam to subject parameters (not only date values).

• Problem with PL/SQL insert query

  Hello to all the genius... Vikram im, Im new in the world of the apex and pl/sql... I need everything that you guys help... This is my first application user (for example)
  
  name of the table - form
  name of the column - f_no number, name varchar2, number of salary.
  Apex page n - p1_f_no, p1_name, p1_sal
  
  Now my problem is the query that is below works in the workshop of sql (insertion of data in the table in shape) and can be seen using the select query... but when I implement this in the apex... It shows - in all areas:
  
  declare
  v_no number (3);
  v_Name varchar2 (20);
  v_sal number (10);
  Start
  Insert in the form values (: v_no,: v_name,: v_sal);
  end;
  
  IM using this query in the Process button,
  
  Thank you
  
  -Best regards,.

• Insert the problem using a SELECT table with an index by TRUNC function

  I came across this problem when you try to insert a select query, select returns the correct results, but when you try to insert the results into a table, the results are different. I found a work around by forcing a selection order, but surely this is a bug in Oracle as how the value of select statements may differ from the insert?
  
  Platform: Windows Server 2008 R2
  11.2.3 Oracle Enterprise Edition
  (I've not tried to reproduce this on other versions)
  
  Here are the scripts to create the two tables and the data source:

  CREATE TABLE source_data
  (
    ID                 NUMBER(2),
    COUNT_DATE       DATE
  );
  
  CREATE INDEX IN_SOURCE_DATA ON SOURCE_DATA (TRUNC(count_date, 'MM'));
  
  INSERT INTO source_data VALUES (1, TO_DATE('20120101', 'YYYYMMDD'));
  INSERT INTO source_data VALUES (1, TO_DATE('20120102', 'YYYYMMDD'));
  INSERT INTO source_data VALUES (1, TO_DATE('20120103', 'YYYYMMDD'));
  INSERT INTO source_data VALUES (1, TO_DATE('20120201', 'YYYYMMDD'));
  INSERT INTO source_data VALUES (1, TO_DATE('20120202', 'YYYYMMDD'));
  INSERT INTO source_data VALUES (1, TO_DATE('20120203', 'YYYYMMDD'));
  INSERT INTO source_data VALUES (1, TO_DATE('20120301', 'YYYYMMDD'));
  INSERT INTO source_data VALUES (1, TO_DATE('20120302', 'YYYYMMDD'));
  INSERT INTO source_data VALUES (1, TO_DATE('20120303', 'YYYYMMDD'));
  
  CREATE TABLE result_data
  (
    ID                 NUMBER(2),
    COUNT_DATE       DATE
  );

  Now, execute the select statement:

  SELECT id, TRUNC(count_date, 'MM')
  FROM source_data
  GROUP BY id, TRUNC(count_date, 'MM')

  You should get the following:

  1     2012/02/01
  1     2012/03/01
  1     2012/01/01

  Now insert in the table of results:

  INSERT INTO result_data
  SELECT id, TRUNC(count_date, 'MM')
  FROM source_data
  GROUP BY id, TRUNC(count_date, 'MM');

  Select the table, and you get:

  1     2012/03/01
  1     2012/03/01
  1     2012/03/01

  The most recent month is repeated for each line.
  
  Truncate your table and insert the following statement and results should now be correct:

  INSERT INTO result_data
  SELECT id, TRUNC(count_date, 'MM')
  FROM source_data
  GROUP BY id, TRUNC(count_date, 'MM')
  ORDER BY 1, 2;

  If someone has encountered this problem before, could you please let me know, I don't see what I make a mistake because the selection results are correct, they should not be different from what is being inserted.

  Most likely a bug in 11.2.0.3. I can reproduce on Red Hat Linux and AIX.

  You can perform a search on MOS to see if this is a known bug (very likely), if not then you have a pretty simple test box to open a SR with.

• insert calendar problem

  Hi I have a scheduled task that executes the code below, I have problems with it.
  
  what I have to do is
  
  1. get all the records of appoint_table where the servertime is lessthan present (which I'm sure that my request is ok).
  
  2. define a TotalSMSLeft session that gets users credit left.
  
  3. If the credit users is SUPERIOR to 0, follow this
  3. send an email
  UPDATE appoint_table 3 b. delete the server time
  3 c. Select all records that servertime is empty
  3D. Insert in SMS_Records where servertime is empty
  3. remove all records where servertime is empty.
  
  4. If not, remove all records in which servertime is empty.
  
  Maybe I owe a lot of code for what I m doing?
  
  can some help me please with the best code to use
  
  Thank you very much

  I think it's get sent twice because your tag is inside a of your GetSchH1 request, but you also have your tag a loop in the query (query = "GetSchH1"). Delete the query = "GetSchH1" of your tag and it should only send 1 copy of each.

  Also, I would perform your deletions outside your loops - in this way, you only need to do 1 connection to the database to delete everything and you won't delete other records before send you by e-mail.

• Eurotherm EPower controller: query problem

  Hello

  I have a problem with communicating with a controller Eurotherm EPower (with 4 units) by OPC server.

  I use:

  -LV 8.5.1

  -iTools OPC Server 7.50 with a number of product formed the social reason (active license)

  -EPower Firmware v3.01

  Communication between LV and OPC server is made by "DataSocket write" and "Read DataSocket".

  I can write => values without problem I only write Main.SP on the evolution of events user and everything's fine.

  But on reading, I would like to read Meas.I Meas.P, Meas.V, continuous for each unit (up to 12 url request)

  The first reading is ok, so I have values, the url are ok. But after that, it is impossible to put in a loop-online no error, (status = 0 on LV and OPC Server) but the values are not updated with the following query.

  I tried to play with the option "wait for updated value", but without success.

  The only way I've found is to open the interface for server, the device, right click and select "Synchronize Active device". But this option is only a shot and very long because, I guess, he gets everything in the device...

  Another point: it works perfectly with the Engineering Studio, commonly called iTools-iTools. It is a client of the OPC server on my application.

  Another point on the other: when I run my application is the ID_EPower.exe in the list of Windows processes and consume resources (0 or 1%) so he lives.

  Complete, with one hour, I thank them but not way with Eurotherm hotline.

  My question is: Y at - it a particular way to obtain ongoing measures such as sending a query each time or a general property to get updated data?

  I used to cruise control disc from the same manufacturer with no problem and no need to send a request to get the values, but here it is perhaps a different case.

  List of requested URL:

  OPC:/Eurotherm.ModbusServer.1/CLA_Gradateurs.192-168-1-222-502-ID001-ePower.network.1.MEAs.V

  OPC:/Eurotherm.ModbusServer.1/CLA_Gradateurs.192-168-1-222-502-ID001-ePower.network.1.MEAs.I

  OPC:/Eurotherm.ModbusServer.1/CLA_Gradateurs.192-168-1-222-502-ID001-ePower.network.1.MEAs.P

  OPC:/Eurotherm.ModbusServer.1/CLA_Gradateurs.192-168-1-222-502-ID001-ePower.network.2.MEAs.V

  OPC:/Eurotherm.ModbusServer.1/CLA_Gradateurs.192-168-1-222-502-ID001-ePower.network.2.MEAs.I

  OPC:/Eurotherm.ModbusServer.1/CLA_Gradateurs.192-168-1-222-502-ID001-ePower.network.2.MEAs.P

  ... Ditto for network 3 and 4

  I joined the part of the code that is dedicated for the reading of values, but it is not really helpful because I think that my method of reading is correct (data arrive but are never updated) is a 'lack' of command to request that the server acquires new data or a bug with the LV-iTools OPC server interface...

  For LabViewers advanced, I know that my attached code is not optimized and not the smartest, but keep cool, I do not need crazy performance

  Any suggestion?

  So, I was not on the spot for the tests, but now it's ok.

  Several series shares have been made to the walkthrough to the problem, but it's hard to know if all were beneficial:

  -An update of software Eurotherm: 7.50 to 7.68

  -An update of the firmware EPower: 3.01 to 3.03

  - and probably the main cause of the problem: change the cable through a cross-wired (we thought it was, but not in reality...). But even if it is the main cause: how it was possible to receive data by forcing the update in the OPC server... strange.

  Thanks for your help.

• How to remove suspicion used in an insert query - help plss

  I just know that when we create a materialized view it inturn creates a table too and this new object are in the user_mviews and also user_tables.
  So begins my question. We have received a report of the times long SQLs and that is the request below:

  INSERT /*+ BYPASS_RECURSIVE_CHECK */ INTO MVIEW_TEST SELECT * FROM TABLE_TEST;
  

  There is no source/code in my entire DB which has this stmt. But the creation of the mview - MVIEW_TEST has the below script:;

  CREATE MATERIALIZED VIEW MVIEW_TEST 
  REFRESH FORCE
  ON DEMAND
  AS SELECT * FROM TABLE_TEST;
  

  This means when the mview - MVIEW_TEST's get updated that it performs an insert in the underlying table for the MVIEW_TEST too?
  The biggest problem for me here, is that the insert stmt using BYPASS_RECURSIVE_CHECK hint that im not sure why it is used. I want to get that replaced by / * + APPEND * /. But how can I do since I don't raise this INSERT manually.
  Is anyway to stop creating the table when my mview is created? Or y at - it a way to stop letting use this hint - BYPASS_RECURSIVE_CHECK when inserting into the table MVIEW_TEST.

  I want to use the indicator - ADD instead.

  If you want the MVIew using APPEND, then do a refresh by using ATOMIC_REFRESH = FALSE.

  Why do you use APPEND? You already know that it is your bottleneck?

  See also: https://asktom.oracle.com/pls/asktom/f?p=100:11:0:P11_QUESTION_ID:15695764787749

  on the reduction of repeat:.

  and the only way to reduce that would be to use a custom job to refresh the MV and the job would: a) disable indexes b) call refresh c) rebuild indexes with no logging

• Connect query problem

  Hello world
  
  I stuck with a query. Let me explain the situation: I have a table I store the IDS of the logically equal records.
  
  For example;
  A = B
  B = C
  X = Y
  Z = Y
  
  My query must return all equivalent records. If you call the query with the parameter 'A', the result set must contain B and C. And if you call the query with the parameter 'Y', the result set contains X AND Z. I thought I can write the spiritual query using start with connect by statement. But the query does not work as I expected. Here's my code and sample data:
  
  
  
  create table temptable (ID1, ID2 number); /
  
  insert into a values (11,12) temptable; /
  insert into a values (12,13) temptable; /
  insert into a values (13,14) temptable; /
  insert into a values (13,15) temptable; /
  
  
  
  SELECT distinct from ID1
  (
  SELECT * FROM temptable
  START WITH 13 = ID1 OR ID2 = 13
  CONNECT TO NOCYCLE
  (
  (PREREQUISITE ID1 = ID1) OR
  (PREREQUISITE ID1 = ID2) OR
  (PREREQUISITE ID2 = ID1) OR
  (PREREQUISITE ID2 = ID2))
  ) WHERE ID1 <>13
  Union
  SELECT distinct from ID2
  (
  SELECT * FROM temptable
  START WITH 13 = ID1 OR ID2 = 13
  CONNECT TO NOCYCLE
  ((PRÉALABLE ID1 = ID1) OR)
  (PREREQUISITE ID1 = ID2) OR
  (PREREQUISITE ID2 = ID1) OR
  (PREREQUISITE ID2 = ID2))
  ) WHERE ID2 <>13
  
  
  In my example, the definitions of equality;
  11 = 12
  12 = 13
  13 = 14
  13 = 15
  
  When I call the query with parameters 13, I expect to get 11,12,14,15. But it returns only 12,14 and 15.
  
  Thanks for any help or suggestion.

• Insert query

  Hi all
  
  DB version: 10.2
  
  I have table with 8 columns namely num1, num2, num3, num4, num5, num6, num7, num8. I have to insert all these column values in a table with a column "Num".
  

  create table nums_tb
  (
  key char(16),
  num1  char(16)
  ,num2  char(16)
  ,num3  char(16)
  ,num4  char(16)
  ,num5  char(16)
  ,num6   char(16)
  ,num7   char(16)
  ,num8   char(16)
  )   ;
  
  create table nums_tmp
  (
  num1  char(16)
  )   ;
  
  I have to insert all column values into nums_tmp. I have written query like this:
  
  insert into nums_tmp
  select * from (
  select distinct num1
  from  nums_tb
  
  union
  select distinct num2
  from  nums_tb
  union
  
  select distinct num3
  from  nums_tb
  union
  
  select distinct num4
  from  nums_tb
  union
  
  select distinct num5
  from  nums_tb
  union
  
  select distinct num6
  from  nums_tb
  union
  
  select distinct num7
  from  nums_tb
  union
  
  select distinct num8
  from  nums_tb);

  The nums_tb table contains 20 million records. So this insert takes a lot of time around 5 hours. Is there a better way to write this query to achieve the right?
  
  Kind regards
  SK

  Is it possible that we can write the query to improve performance?

  Put separate on the outer query not every query internal, using the union all in inline mode.

  Use parallel DML. Consider using a manual sort area size.

  alter session enable parallel dml;
  
  insert /*+ parallel */
  into nums_tmp
  select distinct nums.num1
  from (
    select num1 num1
    from  nums_tb
    union all
    select num2 num1
    from nums_tb
    union all
    select num3 num1
    from nums_tb
    union all
    select num4 num1
    from nums_tb
    union all
    select num5 num1
    from nums_tb
    union all
    select num6 num1
    from nums_tb
    union all
    select num7 num1
    from nums_tb
    union all
    select num8 num1
    from  nums_tb) nums;
  

• Printable report query problem

  I try to develop a printable report query. I created a report under shared components query which consists of 12 separate queries that collect data are all related to a single page element. The intention is to create a PDF document that is printed to the user on demand that will display all this information on the page element they have chosen.
  
  The query of the report gathers information and generates an XML file in the following format.

  <DOCUMENT>
      <ROWSET1>
          <ROWSET1_ROW>
                           *Data from query 1*
          </ROWSET1_ROW>
      </ROWSET1>  
      <ROWSET2>
          <ROWSET2_ROW>
                            *Data from query 2*
          </ROWSET2_ROW>
          <ROWSET2_ROW>
                            * Data from query 2*
          </ROWSET2_ROW>
     </ROWSET2>
     <ROWSET3>
         <ROWSET3_ROW>
                            * Data from query 3*
         </ROWSET3_ROW>
         <ROWSET3_ROW>
                            * Data from query 3*
         </ROWSET3_ROW>
     </ROWSET3>
  ......
  </DOCUMENT>

  Then, I took this XML file and developed a model RTF using Office BI Publisher and imported as a layout of the report.
  I then connected this provision of the RTF to the report query and he ran. I don't have all the data to print.
  
  I found the reason why that it did not work, it is that the XML file that is generated by the report query is not static. The following XML file that was generated by the report query looked like this:

  <DOCUMENT>
      <ROWSET1>
          <ROWSET1_ROW>
                             * Data from query 3*
          </ROWSET1_ROW>
          <ROWSET1_ROW>
                             * Data from query 3*
          </ROWSET1_ROW>
      </ROWSET1>  
      <ROWSET2>
          <ROWSET2_ROW>
                             * Data from query 7*
          </ROWSET2_ROW>
          <ROWSET2_ROW>
                             * Data from query 7*
          </ROWSET2_ROW>
          <ROWSET2_ROW>
                             * Data from query 7*
          </ROWSET2_ROW>
     </ROWSET2>
     <ROWSET3>
         <ROWSET3_ROW>
                             * Data from query 1*
         </ROWSET3_ROW>
     </ROWSET3>
  ......
  </DOCUMENT>

  So I can't develop a RTF model to display the data, if I do not know where these data will appear in the generated XML.
  
  Questions (I'll offer several POINTS to anyone who can answer all of these questions!)
  
  I use APEX version 3.1
  
  * 1. Why the report query seems randomly to renumber and reorganize the XML it produces? *
  
  * 2. Is it possible to make the report query to display the XML data in the order in which the individual queries are classified each time? *
  
  * 3. Is it possible to designate exactly the lines of sets of lines or lines supported by APEX? *
  
  * 4. Are there other methods can I Explorer to produce this report? *
  
  * 5. Is it a problem because I'm on an older version? Is it not a problem on 4.1? *
  
  Published by: bhenderson on February 1, 2012 08:22

  So, you have 12 separate petitions? No there is no way to join them in a union to build the required data set? Or even using views inline in a query for each set of values?
