Test the oracle insert very very slow

I just created a 11.2.0.3 db based on data warehouse model and tested 10 000 000 insert records through sysbench and took 1 hour.

IT is extremely slow. I did not tune the db parameters still, I guess that the parameters are good for datawarehouse.

Operating system is linux redhat.

Anyone has any advice on this?
Thanks in advance.

If the tool generates separate SQL statements that do not bind variables, it is not terribly surprising that Oracle is much slower than MySQL (especially based on things like what engine you use for MySQL). It is a very bad way to test a data warehouse in general and it is a very bad way to design an application that interacts with a database of Oracle in particular. You need to watch a Statspack / report AWR to be sure, but my guess is that most of the time was spent hard - analysis of 10 million separate queries.

If you really want to optimize a type very non - DW workload that doesn't use bind variables, you can to some extent. But there will be a way of poor Oracle reference or a reference data warehouse loading process.

  • The display is very slow on the Satellite 1800 412

    I installed Windows XP Professional (do not use the Toshiba installation disc) and since then, the display is very slow refreshing when scrolling. It takes about 30 seconds to scroll one page down in Word for example. I tried to install the latest display driver but the installation block. Installing the driver in safe mode works but the computer hangs at startup and I needed to uninstall the driver. The laptop now seems to use a standard VGA driver of XP.

    Hello

    If you install the operating system from the original Microsoft CD you need drivers Toshiba. These drivers must be installed in the correct order. Is very important to install the driver from chipset to the first common modules and if they are available. Please also check what graphics card you have and install a good driver.

  • Insert very slow (XE 11g)

    Hello

    I did a new install of 11g XE by default on a Windows 8.1, and I have to spend in its 1.5 GB of data (50 tables) database. A table contains a blob column, and it has 600 k rows; each line has a blob, and the size of each BLOB can range from 1 KB to 100 KB.

    When you insert this table with blobs, it goes very quickly (50 lines can take 1 second or less) until some point in the insertion of these counts, where it begins to be very very slow (50 may take more than 5 seconds).

    If I cancell all the processes (for example in line 150 000), then I start cero by removing all the tables and adding it again, it goes very quickly to line 150 000 and then I'm getting very slow again. It is not a cache issue (I checked to restart the machine). It seems that he compared to the tablespace more, but I can´t find an answer on this point.

    Is there some clues for this?.

    I'm sorry to ask, I'm not an expert of the Oracle.

    Best regards

  • DVD burner in the new laptop VERY SLOW - PLDS DVD +-RW OF THE - 8A5HH

    I just got a new laptop from Best Buy - Dell Inspiron 3521. There a PLDS DVD +-RW OF THE - 8A5HH drive built in. I tried to burn a data CD, but it failed several times.

    I tried these in the file Explorer and CyberMedia Power2Go Burns, also at the Maximum speed or 24 X. It was using both Philips 52 X speed CDR burning failed at the end, when the burner is trying to close the disc. He couldn't complete a burn speed X 10 (very slow) to Power2Go. File Explorer strangled between 7 X and 10 x to be able to burn and did not show a dialog box saying if the burn is complete or not. He left me guessing.

    It was after a call to Dell technical support and a trip on the Microsoft Support Site to use their CD - RW test online. He said he updated something, but I don't know what.

    I must say it's a disappointment. I think I should have bought a laptop without a burner inside and bought an external burner. At least that way I had have the choice of what I got. This burner is slooowly.

    Anyone have any idea if this can be fixed, or is it just a limitation of the burner is in this laptop? If it is material, well I guess you get what you pay for.

    Dell phone support fixed it. Went to the Microsoft Support website and ran a convenience store of material for DVD players, who suggested the update of the firmware of the player. He did that, and then we went back and burned a disc in the file Explorer and it worked, but only to 10 X I opened Power2Go and burned a disc at 24 X, and it burned successfully. I didn't actually measure the speed (Power2Go shows you that), but it worked well and quickly. I think that the problem was an outdated firmware for the DVD/CD burner. Flashing to the latest firmware fixed the problem.

    I want, I knew that this troubleshooting tool on the Microsoft support site, but now I can not find.

    Hi Gianni,

    I use Nero to burn DVDs, and one of the configurable options is the task of "priority". If I set it to 'high' then my phone behaves as you described, that is very slowly. Check if you have you encode/burn too high task priority.

  • New laptop and download the applications is very slow

    Just bought the new laptop is stuck with win8 as the only thing available.  It took 2 days (11 hours) to open the account of ms to get to email.  Now he's just hanging.  Thought to download ms Pinball, game tried, after an hour, it was 8% done, stopped.  This is typical of access to anything on the net.  Pages that came in a second XP now take more than a minute to 8.  Everything is delayed.

    No I've not added anything, have not changed anything, have read the news and played cards.

    Features are so sensitive that happening sites and programs if I place my hand on the keyboard.

    It's horrible, I can get windows XP and remove windows 8?

    Is there a way to make it useful?

    HELP HELP

    Your question is not very clear.

    As long as you have internet connection, Microsoft Account opening should not take more than a few minutes and you can always connect to Windows 8 without Microsoft Account.

    For new PC, first you need to run Windows Update and install all updates. Even if the updates to day will install automatically, but you can do it yourself too.

    If your internet connection is not fast loading, it might be because update is ongoing enforcement and once installed all updates your PC would be quick. I'm not sure what you are referring to the sensitive features but it could be features provided by the manufacturer of your PC and not as in some Windows PC, you can use your mouse pad to open the start screen or scroll down.

    It is NOT recommended to install Windows XP because it is supported and you download the update or support for Windows XP more.

  • W7 Ent. SP1 x 64 clean install on the new PC - very slow to load after reboot during installation

    Hi all

    I'm busy to install W7 Ent. SP1 x 64 on two computers for a small organization non-profit of my friends, all the similar Assembly (motherboard: ASRock H81M-VG4, CPU: Intel Celeron G1840, transcend SSD). The first PC went perfectly, no problems with the installation at all. Now, I installed the second, but unfortunately the following happens:

    After restarting the installation, was asked to enter the name of the computer normally, and then to set up a password. When I clicked on next (and leaving the word password empty) the whole process seems to freeze a little, and then after a few minutes, I could choose settings updates, after which everything slowed even further. "Finalizing settings" took about three quarters of an hour. Once this done, all slowed even more, and it now displays a black screen telling me that this is not a genuine copy of Windows (had no chance to fill in the key product of course) and after about half an hour he is now "configuration of settings customized for xxxx".

    -EDIT - Windows has begin once (between my opening message and my second post), and it was terribly slow in everything that (like several minutes before opening anything). I installed the LAN driver with the idea of updating all the drivers, but after a reboot it is so late it now already taken 10 minutes to boot Windows (and is suspended in the Welcome screen again).

    I've done an another clean install after using DISKPART to format the SSD, but the same thing is happening again once unfortunately. I installed on a USB bootable, I used to install two other computers as well (one before this one and the other afterwards), and everything is fine with those. Swapping the RAM module for a good known has not changed the situation.

    All comments are welcomed, appreciated, thanks.

    All other essential drivers have been installed: video, Chipset?

    Try the SSD at the other system and see how it starts in the system causes problems.

    Also try the SSD with the painful installation in this computer to see if the problem persists.

    Could contribute to isolate if the SSD.

    If it does not work at the same time, but working again later, it is unlikely that the problem is with Thunderbird.
