How to choose the access method (direct path or external tables) for Data Pump export?

I have this slow data export pump, and I have a few suggestions for settings that might improve the speed. But I can't seem to pass them through the DBMS_DATAPUMP package. Is this possible?

REPORT THE NUMBER OF PUMP_HANDLE: = DBMS_DATAPUMP. OPEN (OPERATION = > 'EXPORT', JOB_MODE = > 'TABLE', JOB_NAME = > 'EXP_DATABASE_370');

BEGIN

DBMS_DATAPUMP. ADD_FILE (PUMP_HANDLE, DIRECTORY = > 'EXP_DATABASE_DIR', FILENAME = > ' MY_DATA_A1.) DMP', FILETYPE = > DBMS_DATAPUMP. KU$ _FILE_TYPE_DUMP_FILE);

DBMS_DATAPUMP. ADD_FILE (PUMP_HANDLE, DIRECTORY = > 'EXP_DATABASE_DIR', FILENAME = > ' MY_DATA_A2.) DMP', FILETYPE = > DBMS_DATAPUMP. KU$ _FILE_TYPE_DUMP_FILE);

DBMS_DATAPUMP. ADD_FILE (PUMP_HANDLE, DIRECTORY = > 'EXP_DATABASE_DIR', FILENAME = > ' MY_DATA_A5.) TXT', FILETYPE = > DBMS_DATAPUMP. KU$ _FILE_TYPE_LOG_FILE);

DBMS_DATAPUMP. METADATA_FILTER (PUMP_HANDLE, NAME = > 'NAME_EXPR', VALUE = > 'IN ("MY_DATABASE_370")');

DBMS_DATAPUMP. SET_PARAMETER (PUMP_HANDLE, NAME = > 'INCLUDE_METADATA', VALUE = > 1);

DBMS_DATAPUMP. SET_PARALLEL (PUMP_HANDLE, LEVEL = > 4);

< < THIS_LINE_FAILS > > DBMS_DATAPUMP. SET_PARAMETER (PUMP_HANDLE, NAME = > 'ACCESS_METHOD', VALUE = > "DIRECT_PATH");

DBMS_DATAPUMP. START_JOB (PUMP_HANDLE);

DBMS_DATAPUMP. DETACH (PUMP_HANDLE);

END;

< < THIS_LINE_FAILS > > line throws an exception:

ORA-20020: error: ORA-39001: value of the invalid argument. ORA-39049: parameter not valid name ACCESS_METHOD;

DBMS_DATAPUMP. SET_PARAMETER (PUMP_HANDLE, NAME = > 'ACCESS_METHOD', VALUE = > "EXTERNAL_TABLES");

Replace < < THIS_LINE_FAILS > > this call fails with the same message

DBMS_DATAPUMP. SET_PARAMETER (PUMP_HANDLE, NAME = > 'ACCESS_METHOD', VALUE = > 1); / * INTEGER does not seem to work either * /.

Replace < < THIS_LINE_FAILS > > this call also fails with a message similar

  • How to make the handles visible direct selection on the pasteboard?

    When I go to for transformation/resize images within frames using direct Selection, I don't see the handles of the image because they are white against a white cardboard.  I use InDesign CS5 (ver 7.0.4) on a Mac. I've been using InDesign for a few years and never noticed that it was a problem; all of a sudden, the handles seem invisble. I don't remember what the color scheme was before. (Maybe I'll lose my mind). The colors did not alter an update? There is an option in the preferences to choose the color of the pasteboard, but this does not seem to have any effect. In the meantime, I can't find the handles to resize/convert images. I can enter a percentage to scale, but it is sometimes useful. How to make the handles visible direct selection on the pasteboard?

    If you're talking about the color of a path and its handles, which is dependent on the color of the layer selection. Go to the layers panel. Double-click the currently selected schema and change the selection to something darker color.

  • HP pavilion 15-e034tx: how to choose the right RAM for laptop

    How to choose the right RAM for my laptop (Pavilion 15-e034tx). I know I should buy DDR3 ram.

    Are there other factors should I consider when buying one? I got 2 slots for ram, which od these combos are possible?

    1-4 + 4 GB
    2-4 GB + 8 GB
    3-8 GB + 8 GB

    Thank you

    From the Manual:

    Two customer accessible/upgradable memory module slots

    Support for dual channel DDR3L (1600 MHz)

    Support 8192 MB RAM system in the following configurations:

    8192 MB (8192 MB × 1, × 4096 MB 2)

    Manual download link

    See page 53 for instructions. Memory access is easy via the service Panel. This is the part number for the approved 4 HP concert module:

    4 GB (PC3L, 12800, 1600 MHz) 691740-001

    http://www.Amazon.com/HP-691740-001-4GB-1600MHz-PC3L-12800/DP/B00CI08FX4/ref=sr_1_2?ie=UTF8 & qid = 1451655870 & SR = 8-2 & Keywords = 691740-001

    A 8 GB module is listed in the manual, and it's a 3rd generation of processor i5 I suspect 2 x 8 = 16 concerts would work, but strictly following the manual your only option is to add a 4 GB for a total of 8. Most users really not more 8 GB and adding a second identical module will allow two-channel operation, so you should see a noticeable jump in the overall performance.

    If you want to return only the rows that contain the string 'TEST', followed by zero or more space characters, followed by one or more digits?

    How about this:

    FROM my_table

    WHERE REGEXP_LIKE(description,'^TEST\s*\d+$')

  • How to choose the scheme of work of a different database instead of the database target

    Hi everyone, can you please answer to my problem.

    Q1.is it is mandatory that the two target schema schema and work must present in a database.if not then How to choose the scheme of work of another data base instead of target database schema. Please suggest.

    __Description__

    My work, my work patterns in odi's in a database schema and target in a different database,
    Now I'm dataserver with identification of the target or credentials of scheme work information.
    Here's the problem.

    I can't see scheme of work in the drop-down list when you create the physical schema with data server with the credentials of the target.

    It's obvious that he cannot show the workschema which presents in an another database.because - database server has the schema of the target database credentials.

    Vice versa

    Please suggest

    Concerning
    Chantal

    Hello

    Your KM will create the tables for working in the schema, you write to and that's why you have the problem:

    create table< %="odiRef.getTable" ("l",="" "int_name",="" "w")="" %="">

    I don't know of an option to replace this 'W' that will say 'go and get work in the staging area, I've specified.

    I guess that you can customize the KM and pass all the commands to Execute on the Source tab, or I guess you could specify the schema for each of the steps to be the logic diagram of the various staging areas.

    BUT I don't know if it would work throughout and I think it will create a massive Mount of work unnecessarily.

    Is there a decent reason why you can not have the staging area on the target?
