How to migrate the data from DB to another DB
Hi folks,
In my project I have one requirement. Let me explain in detail we are maintain two databases one for
master database called *GIIS* and one is history database HIST. Both DB version is 10g R1.
(Both DB’s have same no table as well structures)
1. The GIIS database contains nearly 400 tables (master table as well as temporary table)
each Master table having it’s own temporary table.
2. Whenever we made the entry first it will go to temporary table after authorized that entry it will move to the master table
3. But the temporary table contains the data after move to master table .
4. The temporary table data’s will be move to the HIST database each and every day at the night.
This migration we done through the procedure. After migration complete the temporary table data’s will de deleted.
My Question:
1. Whether it’s good practice to migrate the data from GIIS DB to another HIST DB using oracle stored procedure.
(we created the DB link from GIIS to HIST)
2. If not can any one suggest me the way to migrate the data from GIIS to HIST.?
3. Is there any other possibility to migrate the data from GIIS to HIST with out using procedure?Thanks

Hi Mr.Aman Brother
First of all sorry . I am not saying that don't command my requirement. Just i want know the way of migrate the data from one DB to another DB.
you saying that IMPORT/EXPORT is one of the way to do migration.
But in client side they don't know how to do the IMPORT & EXPORT the database..
Can you suggest me the another way to do that
Arun,
If the client doesn't know how to do exp/imp, I would really doubt and would be immensely concerned before suggesting the client any other way. If they don't know, tell them that there is a concept called test database which is used for learning so they should invest time to learn this technique since the other options suggested by fellow members are far more tougher than this one.

How to migrate the data from DEC RDB 5.1 to Oracle 11g
Hi,
As part of my project, we need to migrate the data from DEC RDB 5.1 present on Alpha server with VMS 6.1 OS into Oracle 11g. The size of the data in DEC RDB is around 40 GB.
Could you please suggest various ways of getting this done in easy and simpler way?
Thanks in advance.Hello,
when Oracle bought Rdb from Digital Equipment Corporation (DEC) in 1994, the name of the product changed from DEC Rdb to Oracle Rdb. Meanwhile the actual version of Rdb is 7.2, so you are on a VERY old version. And that excludes the suggestions from the mentioned note to use a database link from Oracle RDBMS to Rdb, that is simply not possible with that old version of Rdb.
But Rdb 5.1 knew already the Rdb Management Utility (RMU) - I just checked that with Rdb 4.1 which is even older.
There are two commands that are helpful for your task.
RMU/EXTRACT - that writes the metadata into a file. That output helps you to build a script to create all the objects in your target database.
RMU/UNLOAD - that writes the data of each table into a formatted file (one file per table). That output can be used by the SQL*Loader to load your data into the target database.
You can read all details about these commands in the online help on your Alpha. At first, issue the HELP command and look in the output list whether it lists a command RMU or RMU51. Then run that command:
$ help rmu /extract
and
$ help rmu /unload
Replace rmu by rmu51 if the help command shows you that rmu51 exists but not rmu.
There is one caveat. Do you use blobs in your Rdb database? If you don't know that, create an the output with RMU/EXTRACT and search the output file for the string LIST OF BYTE VARYING. If there are none then you have no blobs. If you have some you need to take more care of them, they can't be unloaded into a formatted file, that must happen programmatical. If you have such fields then let me know, then I'll tell you how to get them out of your Rdb database.
Best regards
Wolfgang
P.S.: For Rdb related questions it is better to ask in our Communities at https://communities.oracle.com/portal/server.pt/community/rdb_product_family_on_openvms . That forum is watched by Rdb Support and Development. -

How to Transfer the Data from ORACLE APPS to SAP
Hi Gurus,
Here are my couple of quieries regarding Data Migration from Legacy(Oracle Apps) to SAP.
1. How to link between Legacy system(ORACLE APPS) and SAP ?
2. How to migrate the data from Oracle tables to SAP directly, instead of loading the flat files(.txt, .xls) ?
Please respond to my queries ASAP.
Thanks,
SAPSURE.

Edited by: sapsure on Sep 10, 2010 2:32 PM1. How to link between Legacy system(ORACLE APPS) and SAP ?
If you have SAP PI in place then you can interact with oracle database tables directly from PI and then data can be posted to SAP transactions through IDocs/BAPIs.
If you did not have SAP PI still you can do JDBC connection directly from ABAP program. Not sure about the exact steps check in forum.
2. How to migrate the data from Oracle tables to SAP directly, instead of loading the flat files(.txt, .xls) ?
If you want to directly post the data SAP transactions (I hope not directly to SAP tables) then connection needs to establish through ABAP program or Via. PI.

How to pass the data from a input table to RFC data service?
Hi,
I am doing a prototype with VC, I'm wondering how VC pass the data from a table view to a backend data service? For example, I have one RFC in the backend system with a tabel type importing parameter, now I want to pass all the data from an input table view to the RFC, I guess it's possible but I don't know how to do it.
I try to create some events between the input table and data service, but seems there is no a system event can export the whole table to the backend data service.
Thanks for your answer.Thanks for your answer, I tried the solution 2, I create "Submit" button, and ser the mapping scope to be "All data rows", it only works when I select at least one row, otherwise the data would not be passed.
Another question is I have serveral imported table parameter, for each table I have one "submit" event, I want these tables to be submitted at the same time, but if I click the submit button in one table toolbar, I can only submit the table data which has a submit button clicked, for other tables, the data is not passed, how can I achieve it?
Thanks. -

You cannot use OPEN DATASET to transfer data from application server to presentation server.
You can do the following :
<b>Do 1st point in BACKGROUND</b>
1. Read the data file from application server into an internal table using OPEN DATASET
<b>Do 2nd point in Foreground</b>
2. Once you get the data into an internal table, then use FM GUI_DOWNLOAD to download it on presentation server
You cannot use the above 2 point together in Background because its not possible. Hence you need program it partially in background and partially in foreground.

How to get the data from mysql database which is being accessed by a PHP application and process the data locally in adobe air application and finally commit the changes back in to mysql database through the PHP application.
If the data is on a remote server (for example, PHP running on a web server, talking to a MySQL server) then you do this in an AIR application the same way you would do it with any Flex application (or ajax application, if you're building your AIR app in HTML/JS).
That's a broad answer, but in fact there are lots of ways to communicate between Flex and PHP. The most common and best in most cases is to use AMFPHP (http://amfphp.org/) or the new ZEND AMF support in the Zend Framework.
This page is a good starting point for learning about Flex and PHP communication:
http://www.adobe.com/devnet/flex/flex_php.html
Also, in Flash Builder 4 they've added a lot of remote-data-connection functionality, including a lot that's designed for PHP. Take a look at the Flash Builder 4 public beta for more on that: http://labs.adobe.com/technologies/flashbuilder4/ -
How to delete the data from partition table
Hi all,
Am very new to partition concepts in oracle..
here my question is how to delete the data from partition table.
is the below query will work ?
delete from table1 partition (P_2008_1212)
we have define range partition ...
or help me how to delete the data from partition table.
Thanks
Sree874823 wrote:
delete from table1 partition (P_2008_1212)This approach is wrong - as Andre pointed, this is not how partition tables should be used.
Oracle supports different structures for data and indexes. A table can be a hash table or index organised table. It can have B+tree index. It can have bitmap indexes. It can be partitioned. Etc.
How the table implements its structure is a physical design consideration.
Application code should only deal with the logical data structure. How that data structure is physically implemented has no bearing on application. Does your application need to know what the indexes are and the names of the indexes,in order to use a table? Obviously not. So why then does your application need to know that the table is partitioned?
When your application code starts referring directly to physical partitions, it needs to know HOW the table is partitioned. It needs to know WHAT partitions to use. It needs to know the names of the partitions. Etc.
And why? All this means is increased complexity in application code as this code now needs to know and understand the physical data structure. This app code is now more complex, has more moving parts, will have more bugs, and will be more complex to maintain.
Oracle can take an app SQL and it can determine (based on the predicates of the SQL), which partitions to use and not use for executing that SQL. All done totally transparently. The app does not need to know that the table is even partitioned.
This is a crucial concept to understand and get right. -

What does this mean?
So I browse through forum & i got to know that i need to initial the UTL_FILE_DIR ="C:/OracleProject" in init.ora
So can i edit the init.ora with notepad.When i tried to do that it says permission denied
In my system it shows the init.ora file in path C:\oraclexe\app\oracle\product\10.2.0\server\config\scripts
but there is also other file initXETemp in the same path do i need to do the changes in it.
I have tried even editing the SPFILE as mentioned below:
C:\oraclexe\app\oracle\product\10.2.0\server\dbs\SPFILEEXE - I had edit this file using notepad & set the value of UTL_FILE_DIR ="C:/OracleProject". So next time when i restarted i'm unable to log on to the database.
So i had reinstall the software again.
