How will I know where the time goes when you delete a line?

Dear experts,

Removal of certain rows in a table (approx. 4.9 GB / 2.9 Millon lines) takes an average of.5 seconds each line (on average).

This table contains 3 clues, just I just rebuild. Statistics from a couple of the day before.

I have imported/exported the table to a new schema and destruction prend.002 seconds each line (on average).

How will I know where the time goes when you delete a line?

BTW, this is ORACLE 10 g

Thank you
Serra

There the child tables of this table with FK defined as DELETE CASCADE?

  • How will I know where all the reports of users has access

    Hi gurus,

    We use the Hyperion Financial Reporting 9.3.1 & we have 80 reports & 750 users. How will I know where all the reports of users has access. Where can I find this information. I checked the SSP, it only shows the provisioing details, but not the name of the report. I also checked the Essbase.sec but no use. Where can I get the info. Kindly help me.


    Kind regards
    Kris...

    There is no tool of Hyperion to display easily groups and security filters.

    But it really depends on how you set up your security model.

    Normally, you add users into groups and assign these groups to essbase and reports (via the BEEP groups) cubes, so you can check reports have access to correct group and the users are in a good group.

    There is a security tool to export available here, hosted by Applied Olap, and underground work Olap-based:

  • How will I know where to find an object?

    When there is already an object placed on the block diagram, how will I know where to find it in the hierarchy of the functions Palette?

    (Specifically VI Scripting - crosses, in this case.)

    You can find a range where it is enabled by get the context menu drop down for the item (right-click if you use Windows). In the second section of the menu the first element (in most cases) will be the palette that contains the object.  For the crossbar for GObjects.vi the first item in menu in the second section is VI Scripting palette. For a larger? the first item on the menu is the comparison. A primitive as array to build, you go down to the first element "pellets" in the menu. It is still in the second part, but is not the first item.

    You can also select Replace in this context menu. The first enumerated palette will be the one that contains the item. However, it takes two clicks compared to the other to the above method.

    The Palette list detailed help files have on the line under the name of VI. You can access this by clicking on the link detailed help at the bottom of the window context ehlp.

    If the object is a VI, Show VI hierarchy include VI selected lib and see the full path in the labels of VI will show the location on the disc, but which does not correspond exactly with the paddles.

  • Laptop had a problem to "Solve a problem with PSIKey", solution from Windows & installed according to the instructions. How will I know that the problem is solved?

    has stopped working properly.

    An update is available that solves this problem.

    Downloaded Update site Web Protexis, Inc. and told to follow the steps in the installation wizard. The file downloaded and said he was setting up installation. Then after a few seconds, the box has disappeared and nothing else happened. How will I know if this problem has actually been resolved? My laptop has shown 6 problems with this unit from 30/07/11-08/12/11, where the unit has stopped working. Because I don't know what it is yet, I don't know really if the problem is solved or not. What should I do at this point? I have a SP2 7520-5185, running Vista Home Premium, Acer-Aspire. Thanks for any help you can give.

    Hello

    If you have installed a trial or paid a licensed version of Corel software products, you probably may notice a third unannounced software application makes its way into your computer too. The program is PSIService.exe by Protexis, which installs a Protexis V2 of Licensing Windows operating system service or Protexis licensing service.

    PSIService belongs to protect DRM (digital rights management) copy protection and license management software, which is intended to protect an application or software against piracy and illegal copying. Thus PSI service is normally installed by another program, such as Corel Paint Shop Pro Photo X 2, Corel Paint Shop Pro XI (X 1), Corel Paint Shop Pro X, that uses its service to collect information of license to repatriate much like spyware, protect copy and authenticate the user who is using an authentic version of the program.

    When you tried to download and install the program, if the box that says closed the dialog box when the download is complete has been verified, it will close the dialog box.

    I suggest that you restart the computer and check if you get an error message.

  • How will I know if the processor is 64-bit

    I am looking to buy a laptop Toshiba Satellite A series and said that I should get only one with a 64-bit processor because what it takes for the Microsoft Vista work properly and anything else will be obsolete as soon as next year.

    I looked on the website of intel to get numbers of processors, but they don't seem to even not list all the numbers on the models for sale and it is especially goobley gook for me!

    Help!

    You comment is not 100% good.
    The fact is that Microsoft has designed Vista 32 bit and Vista 64-bit.

    If you use the Vista 32 bit with a 64-bit processor you won't see a better or faster performance. Therefore, you can simply use the Vista 32 bit on the laptop with 32-bit processor with the same performance.

    Of course if you are going to buy a laptop with 64-bit processor I advise to use the Vista 64-bit. You know it; Let's go all the way. ;)

    But as much as I know Toshiba does not own notebooks with Vista 64 bit and you will find also all Toshiba compatible drivers for Vista 64-bit.

    So now, my last question: why you want to buy a laptop with 64-bit processor?

    PS: You can check the CPU specifications in the control panel or you are going to use a tool of diagnosis as Everest

  • How will I know that the synchronization completed successfully and that it is prudent to close the browser?

    I'm working on my desktop PC or on my laptop. The latest Firefox is installed on both computers (FF10.0)

    (1) I don't know if I start synchronization manually (Tools/sync now) or if this is supported automatically on an ongoing basis.

    (2) in any case, how can I know when the synchronization completed successfully, and it is prudent to close the browser.

    I don't want to meet me on the road with my latest password updates or missing bookmarks.

    I do not see in the status information about the synchronization process. It is very disturbing and not exactly which involves trust.

  • How will I know if the text in a cell in Excel blocked fonts?

    I read in a worksheet, excel and read in the text of the cells needed. I want to skip all the cells where the text was blocked (blocked?).

    I tried to use the code:

    error = Excel_GetProperty (ExcelSingleCellRangeHandle, & ErrorInfo, Excel_FontStrikethrough, CAVT_OBJHANDLE, & MyHandle);

    but it did not work.

    Any suggestion?

    Thank you.

    Neil.

    Hi Neil,

    If you use ExcelRpt_GetCellRangeAttribute (CAObjHandle worksheetHandle, char [], int attributeID cellRange, void * attributeValue)

    and use the if... else with the following properties ExRConst_False (Boolean False) and ExRConst_True (Boolean True)

    You should then be able to manipulate if necessary.

    Help with these functions can be found in Labwidows/CVI help OR under library tools > Excel Report > alphabetical list of functions and highlighting the ExcelRpt_GetCellRangeAttribute function.

    Hope this helps

  • How will I know where my CC licenses are used?

    I have several seats of CC for the teams, but they are turned on and off on many computers constantly.

    How can I keep track of what the licenses are in use on my computers? Are the MAC addresses or hostnames stored somewhere?

    If I need to get a license, do I do by the user (e-mail address), or can I revoke a license from a machine instead?

    In fact, Adobe offers by computer or simultaneous license as an alternative to the CC for the teams? How to manage users in the enterprise?
