copy data from one database to another

Hello

I want to copy data from one database to another.

I have two patterns such as

dev1/dev@ORCL
DEV2/dev@DCEL


I have same tables dev1 and dev2 (tables)
but I have not given in dev2 (tables).
now, I want to copy dev1 (tables) in dev2 (tables).

You can also use the database link:

select * from dev1.emp@orcl;

What database are you connected to?
You must create and use the links in the database for all other databases.

For example if you are connected to the database A and to retrieve data from database B, you must create a connection of database in base B

create database link B connect to  identified by  using 'B';

Then you can retrieve data from database B with

select * from [yourschema.]yourtable@B;

This will work only for tables that are visible to the user that you used in the definition of database link.

    Hello

    We have two databases on both exadata machines... we need to transfer a huge amount (more than 50 million lines) data regularly between these two databases...
    One thing we can do is to create the database link between these two databases and data transfer...

    other than that is there a better way in ORACLE 11 g to transfer data... data loading is incremental data load in the tables...

    I would just use a database link. GoldenGate is expensive and powerful, data with filters pump is a bit more complex and cannot be a faster. One thing you could do is to create logs of materialized view in the database of origin and convert the destination in materialized views tables (create a materialized view TABLE_B in select * from TABLE_B@source_database), then use 'RAPID' refreshes to update the data. I did it and I can tell you that discounting 'fast' is actually fast when you keep it simple. But it is perhaps too exaggerated.

  • Need some ideas on the copy of the data from one schema to another.

    Dear all,

    I would like to know the best method and possible by copying data from one schema to another. (I won't use EXP / IMP).
    Example:


    I have a scheme of production on which I have hundreds of tables. I copy the data of the TEST environment after comparing data, I should copy the data incrementally.
    Maybe this copy of data may occur once a month, or on request.

    I want to have this done by a procedure.
    I was thinking about the logic below, using a procedure I will compare the tables and the structures between the two schemas.
    Then I willl use the primary key in both tables column and compare the data first. If the data if it does not exist then I only inserts these records in the target.
    The above said logic could be as similar as the synchronization of data or records, but the table does not all columns to track records archived / copied from the source.
    Suggest me so if you can give me the best logic or solution.

    Thanks in advance...

    I don't know why you don't want to opt for EXP/IMP.
    As an alternative, if you have a link DB between Production and Test pattern (which I seriously doubt), you can use the MERGER to a copy of data from Production to Test Delta.
    a. INTRODUCE IN test_schema.table_name SELECT sequence_columns, column_list FROM (SELECT column_list FROM prod_schema.table_name LESS SELECT column_list from test_schema.table_name)
    Column_list must not contain columns that contain sequence values because they may differ and result in an incorrect result; Therefore, this is taken into account in the outer query rather than Inline mode.
    b. MERGE STATEMENT
    c. FALL of test_schema.table_name. CREATE test_schema.table_name as SELECT column_list from prod_schema.table_name; -A way very neat to copy all the data, provided you do not keep any changes to test the tables in the schema.

    However, you mentioned to find existing records based on the primary key; IMO, primary key is normally a sequence (may be alphanumeric) and its value on env Production and Test may defer or even can have different attributes, therefore, I find it incorrect to match only the primary keys. I would say to match the key attributes.

    If you want to follow the last update/insert for a record, you can add a column that puts the time of last modification. In this way, you can track the changes of a column. Another alternative would be to use a check to the table.

  • transmission of data from one container to another

    Hello

    Let's say I have two containers (Container1 = application, Container2).  Container1 receives data from user, do some search database and displays Container2 with database search results.

    -Container1 (call and display)-> Container2

    Below shows how I use a bindable variable in container1 for transmitting data of container1 in Container2.  Also shows how to display Container2 of container1.

    <! - Container1 - >

    " < = xmlns:mx mx:Application ' http://www.Adobe.com/2006/MXML ">


    ....
    [Bindable] public var foo:String = 'bar ';
    ....
    private void loginHandler(event:LoginEvent):void
    {
    mycontainer2 = new Container2();
    mycontainer2. Name = "mycontainer2";
    this.addChild (mycontainer2);
    }
    < / mx:Application
    >

    I am data access in Container2 as follows:

    <! - Container2 - >

    {mx.core.Application.application.foo}

    T1) is there a better way to transfer data from one container to another and to access the data?

    Q2) is the only way to call and display of the container1 Container2?

    Q3) how can I return to container1 Container2, i.e. Container2 call and display container1

  • Best way to move data from one page to another within the app

    Hi all as I started to write that and was way to complicated to explain in full without a novel.

    Brief description. I use the query string that begins in the parent (from href in JSON) window must then be moved in the iframe url when moving to other pages to avoid security as a page and iframe is conflicting http and https. and are not accessible... It seems that there must be a better way.

    So my question is what is the best way in a platform open to move data from one page to another?

    You do it this way, it's in the menu.json, but when you work within the iframe and if your loading pages in applications using vairable relative URLS cross they come through.
    Discovered only this framework using the browser and you can se the construction and scope of all URLS used.

    The apps are sandboxed you cannot access aything in the parent frame, this is a feature of derliberate if something you can not do.

    As I said, you have a few methods to your own data storage space.

  • transfer of data from one server to another server

    transfer of data from one server to another server... How is possible?

    but

    I would like to know any other comments and other means (like to explore)

    If you move the range of data to load into the different cube, then you can use report script or calc extrcat data and can use the rule files to load the data.
    If you move the data to load into a cube replicated in another environment, you can take the lev0 data and can do the free form of loading.

    with office, follow these steps:
    1. connect to the discoverer desktop computer and open the workbook you want to copy from.
    2. open the workbook you want to copy.
    3. While both are open, press the "Restore down" button in the upper right area of the worksheet. (the Center button of the 3 to minimize, restore down, and close).
    4. now change the size of windows so that you will be able to see two worksheets side by side 1.
    5. place the mouse on the name of the new worksheet, press left click and drag the worksheet in the second workbook.
