• How oracle will show the large amount of data

  Hi all

  I have server Oracle 11 g on linux os 2. Total sga size is 500 MB only. Now, if customs wants to read the 1 GB of data from database, there no sufficient memory in the buffer cache. So how it will work. the transaction will get successful or it will fail.

  And I have another doubt, done oracle can read data from memory only or it can also read directly on the disc.

  Please let know us your opinion. Thank you.

  Please go through the below documents

• Connector using Siebel-OPA BO mapping for the large amount of data

  Hello
  
  We intend to use the approach to mapping of BO to pass several values of OPA to Siebel, which we intend to store in the form of several records in Siebel.
  1. it is recommended to do by using BO mapping?
  2. mapping IO would be preferable, given the size of the data concerned?
  
  Thank you

  Thank you

  For the passage of a lot of data between OPA and Siebel, I highly recommend using a map of IO. You can find more quickly and also, return xml IO will be easier to deal with.

• How to load the large amount of data in 2 tables oracle ~ mill 6 lines-URGENT

  Hi all
  
  
  
  
  I have a file with lines of 6-8 million load us using a direct charge into a temporary table. Then we insert the missing data by research. The data in this temporary table are inserted/updated in table1.
  
  for ex - we have:
  Table1 (key1, key2, key3, key4, key5, col1, col2, col3)
  Table2 (key1, key2, key3, col1, col2, col3) - the only diff between table1 and table2 is key4 and key5 (located in table 1).
  
  First we insert/update data into temporary table table1.
  
  Insertion: insert into table1
  Select * from insert_table where (key1, key2, key3, key4, key5) IN
  (select key1, key2, key3, key4, temporary_table key5
  less
  Select key1, key2, key3, key4, key5 from table1)
  
  
  
  because me to (select all colulmns
  of insert_table
  less
  Select all columns in table1)
  loop
  Update table1;
  end loop;
  
  
  Then we insert/update data into table2 from table1.
  -the only difference in the insert/update is I use partiiton by making the sum of the columns non-cles and inserted the aggregated data in table2.
  
  Insertion: insert into table2
  Select key1...
  sum (nonkey col) over (partition by key1, key2, key3)
  FROM table1 where (key1, key2, key3) IN
  (select key1, key2, key3 in table2
  less
  Select key1, key2, key3 in table1)
  
  
  Update:
  I'm in (select key1...
  sum (nonkey col) over (partition by key1, key2, key3)
  FROM table1 where (key1, key2, key3,) IN
  (select key1, key2, key3 col1 in table2
  less
  Select col1, key1, key2, key3... from table1)
  )
  loop
  Update table1;
  end loop;
  
  
  
  First we insert/update data into temporary table table1.
  
  Insertion: insert into table1
  Select * from insert_table where (key1, key2, key3, key4, key5) IN
  (select key1, key2, key3, key4, temporary_table key5
  less
  Select key1, key2, key3, key4, key5 from table1)
  
  
  
  because me to (select all colulmns
  of insert_table
  less
  Select all columns in table1)
  loop
  Update table1;
  end loop;
  
  
  
  Data is loading properly - IF full charge. As the size of the file grows long OPS in Toad/Session browser - sorting becomes huge.
  
  How can I improve the speed and make it better?

  You can consider using a single command to MERGE instead of your insert and the separate update loop if you're already on 9i.

  In addition, you should consider generating statistics to a minimum on the insert_table using DBMS_STATS. GATHER_TABLE_STATS.

• Advice needed on the way to store large amounts of data

  Hi guys,.

  Im not sure what the best way is to put at the disposal of my android application of large amounts of data on the local device.

  For example records of food ingredients, in the 100?

  I have read and managed to create .db using this tutorial.

  http://help.Adobe.com/en_US/air/1.5/devappsflex/WS5b3ccc516d4fbf351e63e3d118666ade46-7d49. HTML

  However, to complete the database, I use flash? If this kind of defeated the purpose of it. No point in me from a massive range of data from flash to a sql database, when I could access the as3 table data live?

  Then maybe I could create the .db with an external program? but then how do I include this .db in the apk file and deploy it for android users device.

  Or maybe I create a class as3 with a xml object initialization and use it as a way to store data?

  Any advice would be appreciated

  You can use any way you want to fill your SQLite database, including using external programs, (temporarily) incorporation of a text file with SQL, executing some statements code SQL from code AS3 etc etc.

  Once you have filled in your db, deploy with your project:

• When I scroll with the wheel of the mouse Microsoft Wireless Mobile Mouse, it jumps instead of sliding to the bottom of the page. It ignores even the large amounts. This can be solved? Rose

  When I scroll with the wheel of the mouse Microsoft Wireless Mobile Mouse, it jumps instead of sliding to the bottom of the page.  It ignores even the large amounts.  This can be solved? Rose

  Hi Rose,
   
  The problem occurs on specific applications?
   
  This can be for one of the following reasons:
  1. bad mouse is selected in the IntelliPoint software.
  2. conflict with other mouse or pointer (non-Microsoft) software.
  3. problem with IntelliPoint software or drivers.
  4 application does not correctly recognize scrolling the mouse messages.
   
  I suggest for the link and follow the steps in the KB article:
  The problems with the mouse button or scroll the parameters
  http://support.Microsoft.com/kb/303091
  Note: Put the computer to normal mode after the troubleshooting in clean boot mode.
   
  Hope this solves the problem. If the problem persists, you can write to us and we will be happy to help you further.

• Looking for ideas on how to get large amounts of data to the line in via APEX

  Hi all

  I am building a form that will be used to provide large amounts of data in row. Only 1 or 2 columns per line, but potentially dozens or hundreds of lines.

  I was initially looking at using a tabular subform, but this feels like a method heavy since more than an insignificant number of lines.

  So now I'm wondering what are the solutions others have used?

  Theoretically, I could just provide a text box and get the user to paste in a list delimited by lines and use the background to interpret code on submit.

  Another method that I've been thinking is to get the user to save and download a CSV file that gets automatically imported by the form.

  Is there something else? If not, can someone give me any indication of which of the above would be easier to implement?

  Thank you very much

  PT

  Hi PT,.

  I would say that you need a loading data wizard to transfer your data with a CSV file. 17.13 Creating Applications with loading capacity of data

  It is available for apex 4.0 and distributions, later.

  Kind regards

• How can I find a large amount of data from a stored procedure?

  How can I find a large amount of data to a stored procedure in an effective way?
  
  For example do not use a cursor to go through all the lines and then assign values to variables.

  Leave the query to create the object back to you.

  Declare a cursor in a package specification than the result set gives you desired. And to declare a TYPE in the package specification which returns a table composed of % rowtype to this cursor.

  Then use this type as the function's return type. Here is the code example that shows how easy it is.

  create or replace
      package pkg4
        as
          CURSOR emp_cur is (SELECT empno, ename, job, mgr, deptno FROM emp);
          type pkg_emp_table_type is table of emp_cur%rowtype;
          function get_emp(
                           p_deptno number
                          )
            return pkg_emp_table_type
            pipelined;
    end;
    / 
  
   create or replace
      package body pkg4
        as
          function get_emp(
                           p_deptno number
                          )
            return pkg_emp_table_type
            pipelined
            is
              v_emp_rec emp_cur%rowtype;
            begin
                open emp_cur;
                loop
                  fetch emp_cur into v_emp_rec;
                  exit when emp_cur%notfound;
                  pipe row(v_emp_rec);
                end loop;
            end;
    end;
    / 
  
  select * from table(pkg4.get_emp(20));
  
       EMPNO ENAME      JOB              MGR     DEPTNO
  ---------- ---------- --------- ---------- ----------
        7369 DALLAS     CLERK2          7902         20
        7566 DALLAS     MANAGER         7839         20
        7788 DALLAS     ANALYST         7566         20
        7876 DALLAS     CLERK           7788         20
        7902 DALLAS     ANALYST         7566         20
  

  If you return a line an actual table (all columns of the table) so you don't need to create a cursor with the query a copy you can just declare the type like this % rowtype tables table.

   create or replace
      package pkg3
        as
          type emp_table_type
            is
              table of emp%rowtype;
          function get_emp(
                           p_deptno number
                          )
            return emp_table_type
            pipelined;
    end;
    / 
  
   create or replace
      package body pkg3
        as
          function get_emp(
                           p_deptno number
                          )
            return emp_table_type
            pipelined
            is
            begin
                for v_rec in (select * from emp where deptno = p_deptno) loop
                  pipe row(v_rec);
                end loop;
            end;
    end;

• Is it better to transfer usb2, eSATA (or usb3) in small quantities or large amounts of data? Corrupted data?

  Not sure if this should be in performance/maintenance or hardware/drivers.

  Hello. I was wondering about the usb2, eSATA and a bit on the usb3. I have usb2 and eSATA on my systems.

  Someone I work with told me that there may be corrupted data if you transfer a large amoutns of data via Usb2. It is best to break your files to move, copy, etc., he said. My colleague told me earlier that anything more than 30 or 40 GB start to be transferred correctly from external factors or for some reason any.

  These issues apply to eSATA or Usb3? I guess not, since these other methods are designed to transfer large amounts of data.

  Is this true? Is this due to material limitations? What is the recommended size of transfer? It's Windows XP, Vista or 7 limits?

  Any info or links are appriciated.

  Thank you.

  I have never heard of something like this before and have done some fairly large data movements in the past.  I would recommend using the program Robocopy in Windows Vista/Windows 7 (and available for Windows XP as a download add-on) to drag the move instead of type / move, given that Robocopy includes a number of features and security provisions that are not present in the case.

• Impossible to transfer large amounts of data more than 10 GB

  Original title: the maximum data transfer size?

  I recently installed an eSata controller card in location faster PCIex-1 of my computer to benefit from a transfer of data to and from my Fantom drives GreenDrive, of 2 TB external HARD drive.  When I started to copy the files from that drive to a new drive HARD internal, I recently installed I could not transfer large amounts of data more than 10 GB.  The pop-up message indicating files preparing to copy, then nothing would pass.  When I copy or cut smaller amounts of data all works fine.  Perplexed...

  I think I got the question.  It seems that some of the files I transfer were problematic.  When I transferred in small amounts, I was then invited for what I wanted to do about these files.  Thanks for the reply!

  Speed? Just copy the data files themselves at the level of the BONE. Of course, you use always EXPDP to export the "metadata" for the tablespace but that takes just seconds.

  See and try the example from Oracle-Base
  http://www.Oracle-base.com/articles/Misc/transportable-tablespaces.php

  You can also use the first two steps listed on your actual DB to see if it is eligible for transport and to see what there could be violations.

• Send large amounts of data

  Hi all
  
  I did an applet that receives the data, signs and returns the signed data. When the amount of data is too big, I break into blocks of 255 bytes and use the Signature.update method.
  
  OK, it works fine, but perfomarnce is poor due to the large amount of blocks. Is it possible to increase the size of the blocks?
  
  Thank you.

  Hello

  You cannot change the size of the block, but you can change what you send.

  You can get better performance by sending multiple of your block size of hash function that the card will not do an internal buffering.

  You could also do as much of the work in your host as possible application and then simply send the data you need to work on with the private key. Generate the hash of the message does not require a private so key can be made in your host application. You then send the result of the hash to the card is encrypted with the private key. This will be the fastest method.

  See you soon,.

• Windows xp professional sp3 general system control panel displays the wrong amount of system memory

  Have a Dell Optiplex GX280 running Windows XP Pro SP3 with 3.5 GB of memory. BIOS confirms the good memory installed, but the control panel > system > general tab displays only 2.99 GB of memory.  Is there a fix for this issue or Windows using only the first 3 GB of memory?

  If you have Windows XP with service pack 3 - it's a 32-bit operating system.  The most he could use is 4 GB and some of which will be used for overhead costs.  The most I've seen Windows XP with SP3 report was 3.85 GB of memory - although it is more common to see a 3.25 and 3.5 GB.

  Memory shared (with a video device) can also take off the total.  It's usually anywhere from 64 MB to 1 GB if the video device uses the system memory compared to (or in coordination with) committed memory.

  With Windows XP, however, have probably seldom got you much above 1.5 GB of memory space used without some graphics intense or video edition GOLD of virtual machines.  ;-)

  Essentially - there is unlikely to be anything to fix.  If you want to use/manage better memory, you need a 64-bit operating system (I'm not implying Windows XP 64-bit) and possibly a new video device.
