How to take partial dump using EXP/IMP in oracle only for the main tables

Hi all

select*from v$version;

Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Prod
PL/SQL Release 10.2.0.1.0 - Production
"CORE    10.2.0.1.0    Production"
TNS for 32-bit Windows: Version 10.2.0.1.0 - Production
NLSRTL Version 10.2.0.1.0 - Production

I have about 500 huge data main tables in my database of pre production. I have an environment to test with the same structure of old masters. This test environment have already old copy of main tables production. I take the dump file from pre production environment with data from last week. old data from the main table are not necessary that these data are already available in my test environment. And also I don't need to take all the tables of pre production. only the main tables have to do with last week data.

How can I take partial data masters pre prodcution database tables?  and how do I import only the new record in the test database.

I use orders EXP and IMP. But I don't see the option to take partial data. Please advice.

Hello

For the first part of it - the paintings of masters just want to - use datapump with a request to just extract the tables - see example below (you're on v10, so it is possible)

Oracle DBA Blog 2.0: expdp dynamic list of tables

However - you should be able to get a list of master tables in a single select statement - is it possible?

For the second part - are you able to qrite a query live each main table for you show the changed rows? If you can not write a query to do this, then you won't be able to use datapump to extract only changed lines.

Normally I would just extract all the paintings of masters completely and refresh all...

See you soon,.

  • How to take a screenshot using Windows 7 screen

    I'm using Windows 7 Home Edition. I want to take a screenshot of the homepage of MSN in 31ish Firefox and Internet Explore 11ish to show the difference that I see. MSN.com Firefox display is so bad on my PC that I had to go home pages at http://www.twcc.com/ . I prefer to use MSN.com as I always until they came out with their "New and improved" MSN.com.

    So, if someone can tell me how to take a screenshot using Firefox 31ish MSN.com Web page, I would appreciate the help. Then I'll go to forums on how to do the same thing with the Internet Explorer browser. Then, I'll post the two shots in the Mozilla's Support forums to see if I can find how do Firefox works better for me. Thank you.

    The current versions of Firefox have a built-in feature to take a screenshot as the one of the commands on the toolbar Developer (SHIFT + F2; Firefox 3-bar menu button > developer or tools > Web Developer).

    You can use it if you need only a screenshot sometimes because you must use a command line and can't click a button or use the context menu.

    • A quick way to save a screenshot is to press the 's', and then press the tab key to accept the suggestion of AutoComplete screenshot.
    • You can press the F1 key for context-sensitive help with suggestions where you can select an entry with cursor key and press Tab to copy the entry in the command line
    • You can type a space and two hyphens (-) to see the list of command options and use the Tab key to copy the selected highlighted (for example, fullpage or Clipboard) in the command line entry.

    Note that some commands have their own options and you can type two hyphens at once to see additional options.

    • The default file name is "Screen Shot yyyy-mm-dd to HH.MM.SS.png" in the download directory.

  • How can I add a text field for the main menu?

    I have a project with a menu.  He has a title.  I wanted to add an additional track on the menu, what I had done in an earlier draft.  I would have thought he would have intuitively obvious, as highlighting the existing title I and do a copy and paste.  However, I learned that nothing is intuitive with Premiere elements 12.  Can someone tell me how to get a 2nd title on my main menu?  I have done it before, but apparently did not write it and I was faced with that I falsely assumed would take me 30 seconds to accomplish.  Thank you.

    Rick

    Do you really need a second title for the page in the main menu and the selection of scene or you page fixed for your Adobe title in more than one line?

    I wonder

    I wanted to add an additional track on the menu, what I had done in an earlier draft.

    Is it possible that as soon as you use a theme which came with 'subtitle', as the trip/Beach Resort, not all do.

    Workaround for the title with more than one line of text can backfire on you. But you can try. Excerpt from my first items 13 on this blog

    0019 first Elements 13 movie Menu title question: multiple lines of text


    A first elements 13/13.1 user reports that, if it creates a 3 lines of title text for the main menu of the fake big screen theme in the customization area of Movie Maker project, these 3 lines of text eventually "encoded" in the project of reopening after that that there had been closed.

    We have confirmed this report and extended it to include this problem appears for 13 of Menus other than the fake Widescreen cinema. This issue is not seen in first items 12/12.1 and earlier versions.

    BEFORE REOPENING THE CLOSE SAVE

    Figure 1. Main menu of Spring Flower home with 3 lines of text, as seen before the closure of the Reopen

    AFTER THE REOPENED NARROW SAVE


    Figure 2. Spring Flower main Menu title initially with 3 lines of text, as seen from the closure of the Reopen



    The only way found so far to get the final product to have 3 lines of title text for menus in the final product is to customize the theme to the movie Menu in the customization of the Menu movie of the project area, do not save, close the project at this time and can do the burn to.


    Many variables were examined to explain this behavior. So far, no answer for why.

    If you are determined to use a particular theme that comes with the title menu and subtitle, look at the text of the Palette layers layers in the editing menu .psd file (.psd Editor could be Photoshop CS or higher).

    Regarding

    on my project last year that was the menu that I liked with 2 text fields, I have also got rid of the "arrow" shortly before the text that was the menu key.  Anyone know how I do that?  I can't figure that out now.

    Could you be more specific. But, for now, consider... If you Play All text, you double-click to open the text of the amendment, the deleted text, click OK. Play All disappeared. Sometimes, in page and removal of text "main menu" scene selection to the navigation button... double click on the button to open the changes to the text, delete text, press ENTER, and then bar spacing, and click OK.

    Please let us know if everything above the target you wanted to know.

    Thank you.

    Hi Robert,.

    We understand your problem, but with the subscription online, we can only convert the slides in PDF format. Speaker's notes would not get converted to PDF.

    If you want to convert the speaker notes with slides, then you need to buy the complete PDF solution: Adobe Acrobat

  • Correct a way to clone a new database using EXP/IMP?

    Hello

    What is the right way to import into a new database?

    I have an export to an existing base (say 8i) and I need this clone under a new name (lets assume on the same machine).

    1 export the existing database
    2. create the necessary folders / init.ora / run the db creation script / run catalog & catproc / create TS
    3 import like: file system/password@newdb = full imp = xx is ignore = y

    Set to 'ignore' or not? Anyway what I will meet some errors with sys / tables system; such as:

    IMP-00019: line rejected due to the ORACLE 1 error
    IMP-00003: ORACLE error 1
    ORA-00001: unique constraint (SYSTEM. REPCAT$ _OBJECT_TYPE_PK) violated
    Column 1 - 1005
    Column 2 SYNCHRONOUS EDITABLE TABLE
    Column 3 02
    Column 4
    IMP-00019: line rejected due to the ORACLE 1 error
    IMP-00003: ORACLE error 1
    ORA-00001: unique constraint (SYSTEM. REPCAT$ _OBJECT_TYPE_PK) violated
    Column 1 - 1004
    UPDATE TABLE ASYNCHRONOUS column 2
    Column 3 00
    Column 4

    (BTW... It is a 10 DB g I imported), but I suppose that errors with sys / system would likely happen on older databases as well (for sys or system tables).

    OR is it better to create new DB and import individual patterns?

    Can someone shed some light on the correct way to ensure that the new clone is 100% fit?

    Thank you.
