Incremental export/import

Hi all

I'm migrating from Oracle 8i data DB server to Oracle 11 g on another DB server. I intend to use the import/export method.

Our environment is one of production manufacturing, we want to keep very low downtime.

A normal export of our database takes about 4 hours for us.

Incremental export/import, you shorten this time and it will work for me?

Thank you!

Incremental export/import will shorten the time.

But remember, during an incremental backup to backup updated the table, not only changed records.

Assume that a line has been added in a table after the full backup, then during the incremental backup the entire table is saved again. It is once again a lot of time.

When importing you first apply a full and whole backup by applying an incremental backup it will remove the table and reimport the table from an incremental backup

Thank you

  • under a project to export/import

    Hello world

    as bad students, didn't us use the version included in ODI. On each increment version, we used the export/import process.

    In order to reduce the size of our project, we try to import/export only latest version to a new repository to work.

    The problem that we face is:

    -How easily pass variable project, km, only both of the functions of the repository 1 at rep 2?


    Because we started with an export of the overall project and we are dealing with a 3, 5G XML file, impossible to select only the variables in this file.


    Is there some 3rd party import tool that can help us?

    Thanks in advance.

    You can automate the import / export of all components of the project into a package of ODI. Take a look at the ODI - ODIImportObject and ODIExportObject tools. You can create a procedure that used these tools in conjunction with the use of alternatives to underlying charly ODI working repository tables for the desired information.

  • How export/import prefs.js? Copy of the file does not work

    I want to export/import on: configuration changes. The path is "Firefox/Profiles/i63866ho.default-1384517947097/prefs-js". I also copied prefs.js, all the contents of the file "i63866ho.default - 1384517947097" and the folder "Profiles". Nothing has worked. When I copied prefs.js he did nothing and returns to the old/first prefs.js after restarting firefox. When I copy the file it says that it cannot do.

    Can someone help me?

    Thank you very much

    I'm not very familiar with profiles.ini. There are probably other volunteers who can tell you the best way to add the new (old) profile name to the file.

    The prefs.js file is small, but you mentioned the copy of your extensions as well, so I thought it would be more convenient copy the entire folder. I think that if you can afford the disk space, it is easier to grasp this. That said, some of the information is redundant with, for example, the bookmarkbackups folder contains many safeguards dated (mine are over 1 MB). If you use download sites that use IndexedDB (such as the mega), can have a very large folder indexedDB that you really don't need to carry with you.

  • Is there a switch Terminal to export/import a JSON FILE?

    I need to get and put the Firefox files in an external program, so I need to be able to export/import JSON files programmatically (probably the command line). Is there a switch that I can use, or another way to do this?

    You can do that via the command line.

    There is a daily backup of JSON in the bookmarkbackups folder in the Firefox profile folder

    Maybe you can create a component XPCOM to do what you want.

  • Export/Import Favorites

    I have Windows XP and IE8. I checked help for export/import of Favorites and know it:

    1. Click the Favorites button, click the arrow next to the Add to Favorites button, and then click import and export.

    However there is no arrow next to the add to Favorites button. I remember in IE7 that's exectly so.

    http://support.Microsoft.com/default.aspx/KB/211089/en-us

    Internet Explorer 8 to export the Favorites folder, follow these steps:

    1. In Internet Explorer, click Favorites, click the arrow next to Add to your Favoritesand then click import and export.
    2. Click export to a file, and then click Next.
    3. Click to select the Favorites check box, and then click Next.
    4. Select the Favorites folder that you want to export. If you want to export all Favorites, select the top level Favorites folder. Otherwise, select the individual folder that you want to export.
    5. Click Next.

      Note By default, Internet Explorer creates a Bookmark.htm file in your Documents folder. If you want to use a different name than the file Bookmark.htm, or if you want to store the Favorites exported in a different folder in the Documents folder, specify the new file and the name of the folder.

    6. Click Next.

      Note If you already have a file with the same name, Internet Explorer asks you to replace. Click Yes to replace the file. Click No to provide a new file name.

    7. Click export.
    8. Click Finish.

  • ODI Export / IMPORT

    Hello world

    I'm developing an ETL process in my virtual machine and at one point that I need for my project and models export and import in the environment of my client.

    There is no advice that you guys can give me? How can I use to avoid the lack of references? INSERT? Duplication?

    Thanks in advance,

    Agostinho

    Hi Agostinho,

    Apparently you use ODI 11 g, that this exception has not been, in ODI 12 c, due to the fact that 12 c ODI repositories have an identifier Global unique which guarantees the uniqueness of the object across different repositories work.

    In ODI 11 g, two important facts need to be known (from Doc Oracle):

    Guidelines and rules important export/import

    Due to the structure of the object ID, these instructions must be followed:

    • Repositories of work should always have different internal IDS. Repositories of work with the same ID are considered as containing the same objects.
    • If an export/import operation is performed between two repositories of work/master with the same internal ID, there is a risk of crush objects when importing. Objects of these two repositories that have the same ID are considered to be identical.

    The link: http://docs.oracle.com/cd/E21764_01/integrate.1111/e12643/export_import.htm#ODIDG579

    Then, of course, you try to insert an ID existing in the new repository which is not possible.

    To resolve this problem, you can renumber your repository. Please read carefully how to achieve this:

  • 9i export/import - multiple exports running

    Hi all

    I have a Database 9i running on an AIX machine. I'm trying to export a few patterns.

    accidentally I ran after 2 minutes that I wasn't able to find the process with expdp (instead of exp).

    to my surprise, it doesn't show any error or any matter that the same dump file and logfile are reused

    normally that I know in datapump I can kill by going to prompt export orders, but don't know how I'd do the same thing with the traditional export/import.

    (1) if I kill it of operating system level. He will have to dump of origin file problem as I'm not sure of what process use the dump file to write data

    (2) why it did not any error when running it a second time as it normally gives an error in expdp to logfile if his re-employment.

    (3) is there a link where I can find a good post, containing information or export import tips

    Database: 9.2.0.6

    Machine: AIX

    Thank you

    H,

    Thus, if the main table would exist, then he doesn't average I export dump would be consistent? Even I don't see any errors recorded in the logfile anywhere.

    is there a manual way to perform a check consistency of my export dump file.

    1. I was little confused with the word and the context / term "Coherent"?  Can you specify what is consistent - from your view, so that I can try myself to provide information from my side.

    To be honest, if the export went very well, you would see then all problems.

    Export master table helping - complete/progress of the task (to track the progress of it). Is to contribute to the collection (* as scale all the objects he needs to go through the base on your export type)

    Since then, if dynamic if you want to join some tasks to the existing in progress/task, can he help you.

  • Data Pump: export/import tables in different schemas

  • Office loses datebook categories after export & import the file dba.

    Hello

    After reading a lot of posts, I can't find any that have reported a similar problem, so here it is.  Office loses datebook categories after export & import of a file of dba.  I use Palm Desktop by Access v6.2.2 and a Verizon Centro.  This problem has nothing to do with the synchronization.  I just exported my calendar of events in a DBA file, import the same file and all event categories have been set to "unclassified".  Is this a known bug, or perhaps, the s/n file includes no category information?

    I'm really curious to know if the dba file (archive date?) contains information catergory.

    Thanks in advance,

    CentroIllinois.

    Hello!

    A bit of a limitation of Palm Desktop.  Before you import the file s/n, manually add the category nanes via change categories and then try again to import the file dba.  Due the category names must be exactly the same spelling and spacing as before when they were exported.

  • Export/import a report

    Hi all

    I tried to manage a report to other FMS of export/import.

    I found this good documentation:

    http://en.community.Dell.com/TechCenter/performance-monitoring/Foglight-administrators/w/Admins-wiki/6425.building-a-custom-dashboard-to-summarize-LogFilter-alarms

    export:

    C:\Quest_Software\foglight5\bin > fglcmd.bat - srv 10.4.118.110 - port 8080 - usr foguser - pwd fogpwd123 cmd - m system util:uiexport: sa_salogsummary f C:\Temp\LogFilterSummaryDashboard.zip

    Import:

    $FOGLIGHT_HOME/bin/fglcmd.sh - 10.4.118.110 - port 8080 srv - usr - pwd fogpwd123 cmd - foguser util:uiimport f LogFilterSummaryDashboard.zip

    but my problem is, in this example, the module he wants to export has a good reputation: "system: sa_salogsummary.

    But if I look in my report, it bears the name: "user: saladisc.3" so I cut the '. '. 3 "and does, but as expected it does my all-inclusive usersettings of photos and so on.

    And if I extracted the zip file that was does and only change the wcf.xml of does, deleted all the other reports/dashboards that I don't want and didn't import xml without all the other stuff he does not appear :)

    any ideas how I could get this special report in an another fms? where is my failure?

    Thanks in advance

    The blog article that you referenced, build a custom dashboard to summarize LogFilter alarms describes the difference between data-driven drag and drop dashboards and reports and dashboards WCF based queries and reports.

    The 'special report' you are trying to copy to an another FMS appears to be a drag and drop the report. This report has a number of data views with direct references to the data in your original FMS. None of these specific data elements will exist in your FMS target, so it is unlikely that your migrated report will have any content once you've imported it there.

    The blog post also describes the technique of export and importation of a module of dashboard from a FMS. The system works at the level of a module, so all the views, queries, converters, etc in the module will be included in the export. If you want to export a single view/report and not others in the same module, you need to create a new module, and then (deep) copy the target view/report of the original module in the new module before exporting the new module. The technique of export/import works with both 'system' and 'user' modules, but queries modules WCF-based 'system' are more suited to sharing across different FMS that modules the user with drag-and-drop views/reports with direct references.

    Kind regards

  • DataPump - validate vs export import many records

    All the

    You ask is there any technique to validate the ACCOUNT RECORD between vs Data Pump Export Import, when you only use the option to export DATA_ONLY.

    (1) export DATA_ONLY using Data Pump. (No DB objects or metadata)

    (2) DATA_ONLY using Data Pump import.

    After import, want to compare the number of records migrated on each table are match between vs Export Import.

    Debate with the following options of 2.

    (1) if I compare using LOG files from vs. Export Import (unix more format and compare files)

    (2) generate... SELECT COUNT (*) FROM sql using EXPORT and IMPORT a log file, and then compare these results.

    Please share if someone does something similar. Appreciate your comments.

    Thanks in advance.

    Hello

    > Was wondering is there a technique to validate the ACCOUNT RECORD between vs Data Pump Export and Import, when you only use the option to export DATA_ONLY.

    There is no need to do the whole process, just look for the error in the export/import log file... If you don't get any error means your account is fine... It's enough to validate the registration.

    There is something that I am missing?

    Any idea?

    Concerning

    OK, I found the problem. (less)

    I think this problem is the file system of the old machine.

    The old machine's file system is reiserfs. I have not found any note on the problems with reiserfs, but this is my conclusion, given that all the tests I did.

    This old machine had an NFS volume on a backup server, so I changed to this volume export dump file. Then I transferred the file via scp on the new computer, as I did before.

    Now import worked well. !

    I repeated the steps by changing the backup file to export to back reiserfs volume, only to ensure that I did not make other changes, scp the new machine, and failed to import. So, no doubt. It seems that reiserfs causes a kind of corruption of dump files when they are copied to another file system (but it's weird, because I run md5sum on the two file systems and the result is the same)

    I would like to do another test. So I'll write here the results to confirm and help other people with the same problem.

    Thank you all.

    Hello

    First check the lob corrupt as:

    SQL > create table corrupted_lob_data (corrupted_rowid rowid);

    Table created.

    SQL > set off concat

    SQL >

    declare

    SQL > error_1555 exception;

    pragma exception_init (error_1555,-1555);

    number num.

    Start

    for cursor_lob in (select rowid r, & lob_column of table_owner. & table_with_lob) loop

    Start

    NUM: = dbms_lob.instr (. cursor_lob & lob_column, hextoraw ('889911'));

    exception

    When error_1555 then

    insert into corrupted_lob_data values (cursor_lob.r);

    commit;

    end;

    end loop;

    end;

    2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

    17.

    Enter the value of lob_column: FILE_BLOB

    Enter the table_owner value: hclm_admin

    Enter the value of table_with_lob: SCAN_UPLOADEDFILES_TEMP

    former 6: for cursor_lob in (select rowid r, & lob_column of table_owner. & table_with_lob) loop

    6 news: for cursor_lob (select rowid r, FILE_BLOB of hclm_admin loop SCAN_UPLOADEDFILES_TEMP.)

    old 8: num: = dbms_lob.instr (. cursor_lob & lob_column, hextoraw ('889911'));

    8 new: num: = dbms_lob.instr (cursor_lob. FILE_BLOB, hextoraw ('889911'));

    PL/SQL procedure successfully completed.

    SQL > select * from corrupted_lob_data;

    CORRUPTED_ROWID

    ------------------

    AAASF/AAKAABacyAAA

    To resolve this problem, we have 3 options

    (1) to restore and recover the LOB segment using physical backup.

    (2) empty LOBs affected using the UPDATE, as mentioned in the Note 787004.1statement:

    SQL > update SCAN_UPLOADEDFILES_TEMP

    Set FILE_BLOB = empty_blob()

    where rowid in (select corrupted_rowid

    of corrupted_lob_data);

    SQL > commit;

    (3) perform the export, excluding the corrupt ROWID. by adding the following to export command parameter

    Query =------"where rowid not in (\'AAASF/AAKAABacyAAA\'\) \ \" "

    Kind regards
