The Data Pump export utility provides a mechanism for transferring data objects
between Oracle databases. The utility is invoked with the following command:

   Example: expdp scott/tiger DIRECTORY=dmpdir DUMPFILE=scott.dmp

You can control how Export runs by entering the 'expdp' command followed
by various parameters. To specify parameters, you use keywords:

   Format:  expdp KEYWORD=value or KEYWORD=(value1,value2,...,valueN)
   Example: expdp scott/tiger DUMPFILE=scott.dmp DIRECTORY=dmpdir SCHEMAS=scott
               or TABLES=(T1:P1,T1:P2), if T1 is partitioned table

USERID must be the first parameter on the command line.

  • Data Pump Export Wizard in TOAD

    Hello
    I am new to the interface of TOAD.

    I would like to export tables from a database and import it into another. I intend to use Data Pump Export / Import Wizard in TOAD.

    I installed 9.1 Toad on WINDOWS XP and I connect to the BOX (DB server) using the customer Oracle UNIX.

    I know that the command line data pump process IE $expdp and $impdp.

    But I don't have a direct access to the UNIX BOX, IE the HOST so I would use TOAD to do the job.


    I would like to know what is the process for this.

    How different it is to use the command line data pump... With the help of TOAD where we create DIRECTORY DATAPUMP?

    I can do it on the local computer?

    Basically, I would like to know the process of import/export using TOAD with no direct access to the UNIX MACHINE.

    Thanks in advance.

    I don't think that you can do with TOAD withouth physically copy of the file on the remote host. However, you have another option. "You can use the link to database to load data * without copying it to the remote host" using NETWORK_LINK parameter, as described below:

    For export:
    http://download.Oracle.com/docs/CD/B19306_01/server.102/b14215/dp_export.htm#sthref144
    The NETWORK_LINK parameter initiates an export using a database link. This means that the system whereby the customer expdp is connected contact data source referenced by the source_database_link, he extracted data and writes the data to a dump on the connected system file.

    To imprt:
    http://download.Oracle.com/docs/CD/B19306_01/server.102/b14215/dp_import.htm#sthref320
    The parameter NETWORK_LINK initiates a network import. This means the impdp customer initiates import demand, usually in the local database. This server comes in contact with the remote source database referenced by source_database_link and retrieves the data directly, it rewrites in the target database. There is no involved dump file.

  • Excluding views materialized to a data pump export

    Hello

    I use the Oracle11g 11.1 RAC on Linux version

    I am trying to remove a schema of data pump export materialized views. I used EXCLUDE = MATERIALIZED_VIEW in the
    settings file. The materialized view is not exported, but the table associated with the view is always exported. Does anyone know how to remove those?

    Thank you

    Richard

    You will need to specify the tables in the exclude parameter.

    EXCLUDE the = MATERIALIZED_VIEW would not exclude the paintings of masters associates.

    In a single parameter EXCLUDE specify:
    EXCLUDE THE = MATERIALIZED_VIEW, TABLE: IN "('EMP', 'DÉPARTEMENT')" "

  • Data Pump Export/Import

    Hello Forum,

    I have a question regarding imports and exports of data pump, perhaps what I should already know.

    I need to empty a table that has about 200 million lines, that I need to get rid of about three quarters of data.

    My intention is to use the data pump to export the table and and indexes and constraints etc..

    The table has no relationship to any other table, it is composed of approximately 8 columns with constraints not null.

    My plan is

    1 truncate table

    2. disable or remove index

    3 leave the constraints in place?

    4. use data pump to import a lines to keep.

    My question

    will be my clues and imported too much constraints I want to import only a subset of my exported table?

    or

    If I dropped the table after truncation, I'll be able to import my table and indexes, even if I use the sub as part of my statement to import query functionality?

    My table using the query sub in data pump functionality must exist in the database before doing the import

    or handful of data pump import as usual IE will create table indices grants and statistics etc.?

    Thank you for your comments.

    Concerning

    Your approach is ineffective.

    What you need to do is to

    create the table in select foo * bar where the

    bar of truncate table;

    Insert / * + APPEND * / into select bar * foo.

    Rebuild the indexes on the table.

    Fact.

    This whole thing with expdp and impdp is only a waste of resources. My approach generates redo a minimum.

    It is not possible in data pum export only selective table columns. However you can try next.

    (1) create table export_selective as select c1, c2 from the source table; (you can create it in the source db)

    (2) expdp export_selective table

    (3) export_selective impdp in the target table
