• Bottleneck in bulk updates/inserts

  I worked on doing updates in block and inserts through sqlapi ++ using a library of extention udpate in bulk developed internally long ago. The oracle database is. Inserts/changes in bulk are in batches of 50K. I am facing a problem of very specific performance with respect to these bulk operations.
  
  The first batch of insert in block (50K records) is done within 3 seconds; While the next similar batch for bulk insert or update (50 files again) takes a second huge 373. 'Top' on a RHEL-AS-4 server using, I could see what the oracle process that includes all of the 373 secods for completion; so sqlapi ++ or the in-house name extension isn't the culprit.
  
  The third batch of 50K records in the sequence take much longer (second 913). The time will increase exponentially; and it doesn't seem to be > all < model out of it.
  
  Surprisingly, this is not consistent. On a good day, I have the second batch browsing in 3 seconds. All the documents intact and perfect without any kind of defect in the data. In fact, all of the following prizes would end in or about 3 seconds.
  
  Even more surprising, if I truncate the table and begin the process, the problem will reappear. He would again begin taking 370-380 seconds for 2nd batch. Once again, if I had used "delete from ' query instead of 'truncate table' query to delete all records from the table, there is no problem!
  
  So in short, I came to the conclusion that the bottleneck occurs when the table is truncated (or is created new), and not when all records are deleted using the query "delete from.
  
  All guess why it could be produced? I admit that I am not very good in data bases, so any help would be much appreciated.
  
  Thanks in advance.

  Well, I ran the SPÖ in bulk a new with statspack snapshots before and after the operation. as suggested by Jonathan, used the old hash value (for the operation of your time UPDATING) of the statspack report for sql_id and prepare the execution plan. I could of course.

  Then I recompiled the program to generate the behavior that is 'good '. has run the op in bulk, statspack report generated. and surprise... There is no UPDATE statement in the report. UPDATE was simply not fired by the server; While in the test program, the rows affected by UPDATE operations have been exactly the number of lines in input (which is just, according to the supplied input data). so now it seems that somehow the server decides not to trigger the UPDATE, but still (rightly) returns all the rows as rows affected.

  While I understand that statspack report contains not all queries fired; If the correct entry, to INSERT to get me fired, is fed, the op of the INSERT, which takes considerably takes less time the UPDATE operation, finds its place in the report. so I think that in the case of UPDATE, the UPDATE query is not triggered, and so 'good' behavior reports 3 seconds, while 'bad' behavior that triggers the UPDATE reports 440 seconds.

  - dynamic sampling used for this statement
  

  It seems that I did not yet understand the logic of your 'server' process, but if this seems to be a reasonable explanation to you that, in the case of the 'good' performance update is not performed at all, then this might be the point.

  But looking at the execution of the UPDATE plan you don't think it might be better to accomplish the UPDATE using an index? Is there an index on the parentmemberid columns, the childmemberid and the parentdimid of MDS_MEMBERRELATIONMAP?

  Moreover, it seems that you have no statistics at all on the MDS_MEMBERRELATIONMAP table because the optimizer using dynamic sampling, which takes some time to run because the optimizer runs a query on your table using predicates to check the cardinality in the analysis of the declaration.

  I already mentioned that the execution of a single update requires that an average of 22 000 block gets by executing the statspack report you posted previously. Which is probably due to the carried out full table scan. If the three predicates parentmemberid, the childmemberid and the parentdimid only identify a few rows (or may be even one), then it is probably much faster to have an index suitable for the execution of the update.

• Cannot install Windows in bulk updates

  After a major update (back to top), my computer will only install updates MS 131and I know there are more than 100 more, they have obviously downloaded but have NOT installed. For updates they show has failed, and in the updates installed, they are nowhere to be found. Does this mean "that they have been downloaded, but NOT installed?"  Because I continue to check the updates because I know they are NOT installed and it telling me there is no. To download more than 100 updates one is ridiculous, if it can still be done. After the update it downloaded 1.5 GB of MS updates and the other half has failed. I don't have a choice on my date of restoration, a mouse driver crashed, so the update was important. And the next day he downloaded more than 100. "Should I download these one? If Yes, I switch to Apple.

  Original title: amount of updates

  Hello

  I've seen a number of messages about this problem, so I spent the evening reload an image of two year, perform a new installation of Win 8 who had never had Windows updates...

  For the most part just out of curiosity I guess... and the fact that you mentioned 200 + updates that seemed much too much for me.

  There were 109 updates for my machine. After installation of these groups, I checked once again more updates to Windows, and there is more than 18... A couple less than your total actually. And after checking again once there is no more...

  Your total of 131 is probably correct... I think that you have a gap in your numbers it's because a lot of the first failed and redownloaded again.

  If I go on my updates installed page, it lists 137, even if I downloaded only 127...

  This is because some updates are 'Cumulative' who have more than an update of the package.

  I don't know if I mentioned this in another thread or not, but don't try to do all the updates at the same time... It SHOULD work, but according to the actual updates, they can actually interfere with each other.

  Especially if the .net Framework updates are included. .NET 3.5 in particular. This issue has been much come on the forum, and I'm little tired of repeatedly typing, so I wrote a few notes...

  This is just my opinion, for what it's worth, it's here...

  I just did a test installation 109 updates Windows in groups. All groups have continued the installation process even if they were supposed to be finished, and showed the RESTART...

  You must run the Task Manager to see this.

  I did thirteen .net Framework 3.5.1 updates totaled 206 MB. At least 20 minutes after the RESTART appeared several process continued to run.

  Because I have an application that displays all internet activity, I have seen that Windows Installer would go several times, and when it ran, it would trigger a download of a certain type.

  Two other processes that are running are Windows Module Installer and Windows Module Installer Worker.

  In Win 7, they are called "mscorsvrs" and after you have installed a .net Framework update there are sometimes up to three who take turns running. The best I can describe their function, they're afflicted a compiler.

  Even if the installation is supposed to be completed according to Windows Update, it is not. Not until the end of the process...

  This is the source of many problems with the updates of Windows not... Over the years, I saw countless times in which an update failed after that these processes started to run... To the beautiful environment of the rest updates.

  It's the sequence, I used to install updates 109 @ 1.22 GB on a computer where Windows Update had never been performed...

  Group #1... @ 128 MB's malicious software removal tool and Windows Defender... Then restart

  Group #2... Graphics, internet explore ActiveX

  (Updates of seven first in the list before the .net start) 7 @ 188 MB...  Then restart

  Group #3... .NET framework 3.5.1...  13 @ 105 MB...  It took about 20 minutes for the CPU go to zero before rebooting, as mentioned above...

  Group #4...  .NET framework 4.5...   11 @ 162 MB...   It took about 45 seconds for the CPU to zero before the reboot even if reboot was not required.

  Group #5...  Updates to security...   45 @ 105 MB...     Once again, reboot only after zero CPU

  Group #6...  Important updates...  30 @ 419 MB...     Once again, reboot only after zero CPU

  After installing the first 109, I checked for new updates, and 18 were found @ 579 mb. None were .net Framework... All were successful.

  I actually did this process twice to check it again and with no failure... He managed both times.

  BTW... I have 1.01 GB of updates of Windows to be 'cleaned '... This does mean that they have failed. What is cleaned is the old files that have been replaced and the left on the packages that are no longer needed.

  Kinda like your TEMP folder where a large number of programs store the installation files... After a week, disk cleanup will allow you to remove...

  Published by: user8848256 on November 13, 2009 18:15

  No data found is not an exception that is thrown when an UPDATE cannot find all files.

  % ROWCOUNT SQL can be used to determine the number of rows affected by an update statement, but if 0 rows are updated, no exception will be thrown (it's just not how things work).

  If you post your real return of CURSOR (injured), it is quite possible, that we can help you create a single SQL statement to meet your needs (a single SQL will be faster than your current implementation).

• DirectX, d3d9.ll & d3d10.dll and Windows Update does not work... (Same problem?)

  I had some problems with my computer lately...

  The first thing I noticed is that I failed to run games and applications and I got this weird error 'missing d3d9.dll' and something in style with... "it could be fixed if you have reinstalled the application," but it didn't and I kept getting the error, then I went to see if there was even a d3d9.dll or a d3d10.dll - but it was not...

  Then. I tried to download em for the internet, but later, I noticed that they were for DirectX and therefor was not sure I had good... Then I went to update my DirectX - but failed. He says that I already had an update of DirectX version and it refused to install. I however, perhaps I could uninstall directX, but I couldn't find where and how...

  Then I however, maybe it's because some weird windows update problems - so I went to check how many updates there. I check it the day prior to that, but all of a sudden there are 14 new updates that I had not installed yet (overnight 14 new updates!).

  Does anyone have a solution to this? Please, I desperately need help!

  Hi exique,

  1. don't you make changes before the show?
  2. on what game and application that you get this error?

  DirectX runtime for end-users (also known under the name of DirectX) is an extension for the Microsoft Windows operating system that provides a set of quick material orders, low level that they can use to improve performance for Windows games and multimedia programs. The current generation of Windows games and multimedia programs does not work properly without DirectX. So, by design, you cannot remove DirectX.

How can I remove that annoying popup which does not in any case all in ensuring that I have updated to the latest version?

  Some Firefox problems can be solved by performing a clean reinstall. This means that you remove Firefox program files, and then reinstall Firefox. Please follow these steps:

  Note: You can print these steps or consult them in another browser.

  1. Download the latest version of Firefox from http://www.mozilla.org office and save the installer to your computer.
  2. Once the download is complete, close all Firefox Windows (click on quit in the file menu or Firefox).
  3. Remove the Firefox installation folder, which is located in one of these locations, by default:

• Satellite L750-1NF - I want to remove ODD and put the new SSD

  Hello everyone.

  I have this laptop and I want to improve it with SSD.
  I want to remove the optical drive and buy a mount for SSD. But I don't know with mount I can buy.

  I see [this | http://www.amazon.com/Silverstone-Tek-2-5-Inch-Conversion-TS08/dp/B00AFP89F8] but I'm not if it fits.

  Can anyone help please?

  Thank you very much.

  This isn t possible upgrade for all laptops available on the market.
  I know some laptops Toshiba supported Bay select option in the past.

  This was the case for certain series Portege and Tecra but my knowledge, don t support Satellite notebooks these updates.
  Of course, I could be wrong but I think the BIOS won't recognize the device.

  If you want to use a SSD drive, you will need to replace the internal HARD drive.
