Copy data from one schema to another. Reopen the Question
HelloI had asked this question earlier to copy data from tables of one schema to another in the same database using the database link. In my previous post have mentioned below.
Now I am faced with the question for the remote copy of database
I have created a DB connection between my local system and the remote database. with the chain of connection as shown below
CREATE THE DATABASE PUBLIC LINK "MERU_DEV_LOCAL_DEV".In the above script
CONNECT TO MERUDEV IDENTIFIED BY MERUDEV WITH THE HELP OF "MERUPROD";
I try to copy remote database to my local database tables using the script below.LOCAL DEVELOPMENT scheme IS
REMOTE schema is MERUDEV
network_link DEVELOPMENT impdp = schema MERU_DEV_LOCAL_DEV = MERUDEV remap_schema = MERUDEV:DEVELOPMENT TABLE_EXISTS_ACTION = REPLACEBut the copy of the table does not occur. What could be the problem? Please suggest me or do I need to modify the script
Thank you

LKM to move data from one schema to another in the same DB
Hello
I am new to ODI. My question is simple:
I created a mapping to move data from a table in Figure 1 to another table in Figure 2 (the two schemas in the same Oracle DB.
What is the best LKM Oracle for performance to use in this case? Most of the LKMs using DB link... but is it really necessary that the two schemas are in the same DB?
Ive used SQL knowledge SQL module, but I guess it's probably slower strategy.
Thank you!

Hello
If two phyiscal patterns are on the same database, you want a Phyiscal server with two patterns of phyiscal under this server in your topology, this way ODI will recognize that you don't need a LKM (at all) and mapping will have to IKM / CKM only.
If ODI is to ask a LKM, looks like the two schemas to belong to their own physical server in the topology browser? In this case, it is not optimal.
Just make sure that your user has access to two objects in diagrams and you'll be fine.
If you really want to go Oracle DB Oracle DB then DB link or Datapump for large volumes of data, JDBC/Agent (SQL for SQL) for smaller volumes.

This script will copy only the tables that are not out? If the output table it does not copy the data?
For example > EMP table is DEVELOPMENT exist BUT without data, in this case it does not copy the data.IF EMP table does not exist, it will create the table and copy the data.
If the table exists, then DP he falls and created again with the structure and data.
If not - only creates -
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...

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.

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. Published by: hm on 10.08.2011 22:15

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.

I use windows media play to organize my music with various information. I recently bought another computer to contain music. Copied music from the folder on a windows xp on a windows system system 7. All data for all columns except columns Custom1 and Custom2 was preservered. Is this a known issue? If so, is there a solution? If there is not a fix is there a workaround. Which is a file that is associated with the music files that can be retrieved and updated with the correct information.
Note the same issue occurs on the same system for the music that resides on an external hard disk if the hard drive is cut then re add the files to the library and once they are added all the previous metadatsa entered for all the columns are again the same as previously entered excpet for the the cutom1 and the custom2 colums
Has anyone seen this problem and if yes anyone knows how to avoid losing information that is added to the custom1 and custom2 colums

Export data from one schema to another SQL schema
Hello.
I have 2 plans. One is called MICC_ADMIN and the other is called MICC_PROD. What I want is to export from MICC_ADMIN to import into MICC_PROD. I tried to do with the tool of data workshop, one of the table has approximately 19,000 records, so he gets frozen trying to export data. So I was wondering if is it possible to do this via the sql command. Thank you.
Best regards, Bernardo.Hello

Then sign in as MICC_APEX_ADMIN and runGRANT SELECT ON MICC_APEX_ADMIN.SRDB_MAIN TO MICC_APEX_PROD;
Then log in as MICC_APEX_PROD and INSERT performance

And can you describe your condition more clearly?
My question was... you try to copy the incident followed summary on behalf of the task? In this case, you will need to find the event that triggers ONCE you have entered your resume. Enter in the preview, select display custom events and see what events are triggered. These are the 'moments' that you can use to add additional programming.

Hello
Is it possible to copy sheets from one workbook to another in the same sector of activity? (discoverer more 10g v 10.1.2.55.26)
Thank you
Select this option.Hello
It is not possible to use the most.
It is possible to do so using the Discoverer Desktop edition.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.You move the worksheet from one to the other, if you copy the worksheet to another workbook, and then before you start duplicate the worksheet and accomplish the foregoing on the duplicated worksheet.

When I copy something from one page to another, it seems to change text color or background, that I do not understand why he never used to do.
Whether it's text or only a shape it changes its color to something else when I copy and paste on.
Do you mean 'page' or 'site '?
If you copy something from another site, the reason may be, to have different, but all also named colours on each site.
It would be normal and causes the noticed effect.

transfer of data from one server to another server
transfer of data from one server to another server... How is possible?
We used to transfer data of one cube to another using... report script... then load rule... so can we use even for that?
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. -
