• Performance problem when inserting in an indexed table space with JDBC

  We have a table named 'feature' that has a "sdo_geometry" column, and we created the spatial index on this column,
  
  CREATE TABLE (ID, desc varchar, sdo_gemotry oshape) feature
  
  CREATE INDEX feature_sp_idx ON feature (oshape) INDEXTYPE IS MDSYS. SPATIAL_INDEX;
  
  Then we executed following SQL to insert some 800 records in this table (we tried this using the DB Viewer and)
  our Java application, both of them were using JDBC driver to connect to the database oracle 11 g 2).
  
  insert into feature (id, desc, oshape) values (1001, xxx, xxxxx);
  insert into a values (id, desc, oshape) feature (1002, xxx, xxxxx);
  ...........................
  insert into a values (id, desc, oshape) feature (1800, xxx, xxxxx);
  
  
  We met the same problem as this topic
  Performance of the insert with spatial index
  It takes almost 1 dry for inserting a record, compared with 50 records inserted per second without spatial index.
  which is 50 x slow performance when you perform the insertion with the spatial index.
  
  However, when we copy and paste these scripts inserted in Oracle Client(same test and same table with spatial index), we got a completely different performance results:
  more than 50 records inserted in 1 seconds, as fast as the insertion without having to build the spatial index.
  
  Is it because that the Oracle Client not using JDBC? Perhaps JDBC has been something bad when updating of these tables indexed on the space.

  JDBC normally use autocommit. So each insert can leads to a commit.
  I know not all customer Oracle. In sqlplus, insert is just an insert,
  and you run "commit" to commit your changes explicitly.
  So maybe that's the reason.

• Qosmio G50-12 X - Windows 7 performance index decreased

  After having changed the HARD and WIN7 32-bit drive to SSD and Win7 64 bit Windows Experience Index decreased:
  for processor - 6.1 to 3.9
  for memory (RAM) - 5.9-4.5.

  This isn't good, is it?
  Does anyone know what might be a reason?
  Does anyone have the same problem?

  All the official drivers for Win7 64 (chipset, video, etc.), tried to install different versions for other OS-did not help.
  PC: Qosmio G50-12 X (PQG55E).

  You have changed the system to 32 bit to 64 bit.
  There is a difference between 64-bit and 32-bit system and therefore the performance index will also be different.

  To be honest, I don t care about clean internal Windows experience index.
  Firstly this Index isn't very useful because any change in the system may affect the unique results. So the results are not very significant.

  If you want to get more details about Windows 7 performance index, I recommend this MS site:
  http://Windows.Microsoft.com/en-us/Windows7/products/features/Windows-experience-index

  However, the upgrade of the SSD HARD drive is the best decision you could ever made.
  I also changed the HARD drive to SSD drive and the performance gain is huge

• Satellite P200-1FZ: Question about Vista performance index?

  I recently bought a P200D-128 announced as having 256 MB of memory graphic dedicated only to find only has a HD2400 with 128 MB card (the name must have been an idea, I know).

  I was looking for a model with 256 MB I had read that it was recommended for good graphics performance in Vista.
  On the P200-128 model Vista performance index showed:

  Processor: 4.8
  Memory: 5.9
  Graphics: 3.3
  Games graphics: 3.7
  Hard drive: 5.2

  If the overall score of 3.3 seems not be limited by the graphics performance.

  I now plans to upgrade this model to a P200-1FZ (which has a HD2600 with 256 MB memory card), but would like to know if it significantly improves the score of graphics and Vista performance index.

  If anyone has this model (or a relative) and could tell me the VEI score, I would be very grateful.

  Thank you.

  Hello

  Just FYI: I Satellite P200D-111 with ATI Mobility Radeon X 2600 almost 5 months now. I use Vista Home Premium and to be honest, I'm quite satisfied with the performance of Vista. Up to now, I also tested with several games such as Call of Duty 2, Call of Duty 4, El Matador and older games like FarCry and Max Payne 2 WXP. It works perfectly.

  I like Call of Duty 4. He funs all simply fantastic. I do not even use complete running. At the moment I think to upgrade RAM to have better running OS. in the end, I can say one thing: for the reasonable price, I have large notebook.

  Good bye

• Satellite A100 - low Windows Vista performance index

  Hey there,

  I bought a Toshiba Satellite A100 just for more than a year now with Vista Home Premium. I recently formatted the laptop and installed Vista Business. When I got Home Premium, my 'Windows experience index' (found in Control Panel > system) has been a 3.0 for the graphics. Under Business, is however now that 1.0. I guess that it has not detected the graphics hardware on my laptop.

  How do it detects hardware?

  > I guess that it has not detected the graphics hardware on my laptop.

  I put t know what do you say that it has not detected the graphic material, but you should definitely check out if the graphic and other driver drivers Toshiba have been installed on your laptop properly.

  In addition, the Windows Vista experience index can change and can go down if more programs are installed on the system.
  I noticed that my Windows Vista performance index decreases every time if a 3rd party application has been installed and then removed from the system.

  In my opinion, Windows Vista index experience might be less because you have installed a newer version of the Vista operating system which contains functions of Vista more and so would need of more resources.

• Performance index Windows sides my RAM at 5.5, how can I increase this score.

  I have Windows 7 Home Premium 32 bit, and the performance index scores my RAM to 5.5 (lowest score).  I have 4 GB of RAM installed, which is the maximum 32-bit windows can use.  Because a maxed out what's a low score?

  -Mike

  Because it has to do with the amount of RAM you have, but rather that it's good. What you have in your computer is probably some 800 MHz RAM, which is realitivly slow compared to my 1600 MHz... that is much faster.

• Delete Performance index organized Tables

  Hello
  
  We are experiencing some performance problems with one of our tables.
  
  We have a table (test), which contains 9 columns:
  
  A number (10) not null not pk,.
  B number (10),
  C number (10),
  D number (10),
  E number (10),
  F varchar2 (30),
  F varchar2 (2),
  G varchar2 (2),
  H varchar2 (250).
  
  The table test is an ITO (Index Organized Table) in configuration of default ITO.
  All columns are often necessary for we can not all overflows.
  
  The table has currently 8 m records, which is roughly 1/2 years of a data value, so insignificant.
  Inserts and updates are fine, but it takes 40 + seconds to delete a single line!
  
  (remove test where a = 3043 ;))
  
  If I convert this table in a standard table, deletes are only 0.5 of a second?
  
  No idea why the delete statement takes an excessively long time on the IOT, or what I could do wrong?
  
  Thank you
  Victoria
  
  Oracle Enterprise version 10.2.0.1.0
  Oracle XE version 10.2.0.1.0

  It seems as if the PK on this table of ITO is referenced by a FK on a child table (big enough) but the FK does not have an associated index.

  Deleting a line in this table, Oracle is required to perform a FTS on the child table to make sure that there is no matching FK.

  Find out if you have indeed a FK that refers to this table, and if CF is indexed.

  Just a guess, of course. A long track during the delete operation should be noted where Pio come just to be sure.

  See you soon

  Hi Rohit,

  Thanks for posting your question on the Microsoft community.

  I would like to know some information about the problem so that we can help you better.

  1. What is the brand and model of your computer?
  2. is your computer connected to a domain network?

  Thank you to provide detailed information and screenshot of the question and your efforts

  the solution there.

  This problem may occur either corrupt drivers installed or due to missing or corrupted Windows files.

  I would suggest trying the following methods and check if it helps.

  Method 1:
  Date of display drivers and chipset of your computer from the manufacturer's website and check.
  Refer to this article:
  Updated a hardware driver that is not working properly
  http://Windows.Microsoft.com/en-us/Windows/Update-driver-hardware-ISN

  If this does not help, use method 2.

  Method 2:
  Run the system file checker (SFC) and check the issue.
  Reference:
  Use the System File Checker tool to repair missing or corrupted system files
  http://Support2.Microsoft.com/kb/929833

  System File Checker is a Windows utility that allows users to find corruptions in Windows system files and restore the damaged files.

• WEI - the Windows of your system performance index could not be calculated.

  Hello

  Ive installed a clean copy of Windows7 64 bit, on a formatted hard drive. I am unable to execute WEI.

  I've updated the BIOS for my M3A79-T DELUXE for later (1303 rev). Installed the latest drivers for hardware and Windows was last updated.

  I ran CHKDSK/f/r/x c: (I saw on a Web site that's the problem for one person)

  checked everything is installed ok and there is no conflict in Device Manager.

  Index of Windows performance has a logfile '% SystemRoot%\Performance\WinSAT\winsat.log '. This can give a few pertinent details.

  I got the same error message and, in my case, the log file reported "Unable to save". He seems to have been Kaspersky Internet Security 2010 that blocked WEI to save the results. The full test of the WEI ran OK and even flashed-up the message 'done', but this was then immediately replaced with the message 'assessment could not be completed'... because he could not * recording * results.

  Can I suggest you try another AV package? If you disconnect the network cable, you can safely uninstall your existing AV package and see if WEI works again. If that solves it, perhaps you need another AV package in the future.

  Personally, I found that Microsoft Security Essentials seems not to have this issue and I can now my notes again. But I can try a few other (try before you buy) packages to see which is better.

  Worth a try?

• Insert parallel use

  What does that last statement?  It is as if the query is executed without any evidence.

  doc Oracle:

  Using the parallel execution

  Examples of parallelization of Distributed Transaction

  This section contains several examples of distributed transaction processing.

  Example 1 Distributed Transaction parallelization

  In this example, the DML queries a remote object:

  INSERT /* APPEND PARALLEL (t3,2) */ INTO t3 SELECT * FROM t4@dblink;  

  The query operation is executed serially without notification, because it refers to a remote object.

  UPDATE: this comment is nonsense - see more of the two comments.

  I think the manual is misleading.

  The Insert CAN run in parallel and can be more effective for parallel execution, since two slaves PX can write to disk twice as quickly in one sitting, notwithstanding the fact that the QC distribute data to the PXs. The select statement must serialize the data link-, but the query sent to the remote database could still be parallel to the remote database.

  Here's some output showing the insert might do are parallel, in the way (10.2.0.4 rather than manual 9.2.0.x referenced the OP):

• performance index

  Hi Experts,
  
  I use ecm11.1.1.5, my client has the following question:
  
  After you create a new doc with api RIDC, index will be updated after a few seconds, so after 1 or 2 refresh page click, customer can find the created new doc in the doc list, the list of doc is returned using api RIDC of research.
  
  My client wants to improve the performance of the index so the author can see that the doc is in the doc just after that that he created the list rather than wait for several seconds, is this possible?
  
  Best regards

  By definition, no. Wait for the item to add to the search index before you can search for it.
  I guess you could speed up the process by jumping all the conversions. Or installation of bigger equipment.
  But the entire process should take only a second or two. Your user name has just need a bit of patience - it's not like it takes an hour.
  Here is a simple trick - put a "transformation" icon turns on the screen. This "misuse" should allay the.

• Partial insertion with secondary index

  I would like to use partial inserts (DB_DBT_PARTIAL).
  However, I also need secondary indexes. Now when I insert partial data, the secondary index function is called immediately, but again, I don't have enough data to calculate the secondary key. I tried to provide some app_data is the DBT, but it does not reach the secondary index function.
  Is it possible that I can use partial inserts as well as secondary indexes?

  Hello

  Your secondary index callback function detects when there is not enough data to generate the secondary key? If so, you can return your callback function DB_DONOTINDEX.

  For more information about DB_DONOTINDEX, see the db-> documentation here: http://download.oracle.com/docs/cd/E17076_02/html/api_reference/C/dbassociate.html

  DB_DONOTINDEX basically tells the library is not to create a secondary key for this record. Subsequent updates to the data structure (that do contain the data that you need) can then return the value of secondary key appropriate to the callback function.

  Kind regards
