Loading from MS SQl Server to Oracle

Hello,
I am trying to load data from MS SQL Server to Oracle using LKM SQL to ORACLE, this works well with the tables with less number of rows but I have some tables with rows over few Mils so I am trying to use BCP to export into a flat file and then use SQL LDR to load into Oracle.
My problem is ODI sits on UNIX and dosent support the BCP file format. Has someone ran into similar situation or have a solution to this?
Thanks!

Hi Srinivash, You can follow below KMs
1. LKM SQL to SQL
2. CKM ORACLE
3. IKM SQL Incremntal Update (Insert and update)/ IKM SQL Control APpend (Insert only )
Hope it helps.
Thanks

TRANSFER DATA FROM MS-SQL SERVER TO ORACLE

hello everybody
can anyone tell me how 2 transfer or convert data from ms-sql server to oracle
is there any utility
if yes let me know .
thanks in advance

There are various options depending on how much data we're talking about, where you want the program logic, whether it's a one-time migration, etc.
Among the options
- Use SQL Server's DTS
- BCP the data from SQL Server into flat files and use SQL*Loader to load it
- Create a database link using Heterogeneous Services and Generic Connectivity to extract data from SQL Server
- Use the Oracle Migration Workbench, which is now integrated into SQL Developer
- Use an ETL tool like Oracle Warehouse Builder

How to replicate data from MS SQL Server to Oracle

Hi,
Can someone please help me on how to replicate data from MS SQL Server to Oracle 8i database.

Dear,
I'm a student.
I do simple replication on Oracle 8.0.5 successfully. (one master site and one snapshot site). I only use the SQL*Plus and Schema Manager to do.
But when I do advance replication (multimaster replication) I meet many problem. So I don't get the result.
Do you show me the technology to do that ?
Thanks !

Passing from MS SQL Server to Oracle. Options?

Hello,
We are going to be passing from MS SQL Server to Oracle (ver 10.2.0.3 on Windows Server 2003).
It looks like there is no Oracle tool which will translate TSQL code so that an Oracle database can read it.
What can be used to pass SQL Server DML statement TO Oracle? What are the options?
Thanks

Nell,
If you want to translate TSQL to Oracle PL/SQL you have a tool to do that.
This is Oracle SQL*Developer, you can download (version 1.5.1 build 54.40 )from this website:
http://www.oracle.com/technology/products/database/sql_developer/index.html
This is a free tool.
When you use SQL*Developer, you have the menu Migration/Translation Scratch Editor.
For example, you can create a connection directly to your SQL server db, display your TSQL procedures and then translate automatically to PL/SQL.
You can migrate automatically SQL SERVER database, or only several tables to Oracle.
If you have question about this tool, please go in the Database/SQL developer forum
I hope it helps you.

Mireille

Translate Stored Procedure from MS SQL Server to ORACLE 9i

Hi...
I work usually with MS SQL Server, and now I need to migrate an application from MS SQL Server to ORACLE 9i. I think to preserve most of User Interface made actually in MS Visual Basic .NET 2003 and change or "translate" all the MS SQL Server stored procedures to ORACLE 9i(most of business logic was code in Stored Procedures). So I need an advise of how to do that, if there are a tool for migration (tables, PK, FK, Rules, Defaults...etc) and, if possible, a procedure or tips for translate the stored procedures.
Thanks in advance....

Migration from MS SQL Server to Oracle 10g

Hi,
In our application, we are planning to refresh data every one hour from MS SQL Server to Oracle 10g. Can anyone tell me what approach can be followed?
Thanks & Regards,
Faizal MK

Hello,
migrations can be done with the Migration Workbench that is included in the SQL Developer: http://www.oracle.com/technology/tech/migration//workbench/index_sqldev_omwb.html
But your question sounds more like a replication of data than a migration. Please read as a starter the following note in My Oracle Support (former Metalink):
Note 283700.1: How to replicate Data between Oracle and a Foreign Datasource
That note describes ways for the replication in both directions. Please let me know whether this is helpful for you.

Migrating from MS-SQL Server to Oracle

Hi,
Is there any Java Tool to migrate from MS-SQL Server to Oralce?
(My Organization's data is already stored in MS-SQL Server database, now we want to migrate to Oracle;
is there any easy way to pull data from MS-SQL Server and push into Oracle database)
thanks,

I think u should use a third party help to resolve this problem, i use dbload to solve it when i was migrated my data, it can migrate almost any data, it helps me to convert MSSQL to MYSQL, MS access to MSSQL, mysql, csv loader, foxpro and MSSQL to MS access, MYSQl, CSV, foxpro etc. i found it on google search.

One way replication from MS sql server to Oracle 10g

Hi,
We are using Sql server 2005 windows 2003 32 bit and Oracle 10g 10.2.0.3 on linux 64 bit
Is it possible to replcate table data on real time from sql server (2005 32 bit or sql server 2000 32 bit)to oracle 10g running on linux 64 bit?
If yes then what are the steps.
It will be one way replication from sql server to oracle.
Which option is best sql server dts or Oracle Stream replication to replicate table data?
Regards,

If you want to push data from SqlServer, then ODBC, Linked tables, DTS etc.
If you want to pull data from Oracle, then Heterogenous Services / Gateway.

Sending image from MS SQL SERVER to Oracle BLOB

Hey all, we're trying update Oracle via a SQL Server linked server and we're having an issue with a blob column. The update from SQL is:
UPDATE Banner..GENERAL.PS_EBI_IF_TBL
set photo = a.blob_file, photo_change_date=a.blob_date
from PWNT.dbo.BLOBS a, PWNT.dbo.BADGE_V b
where a.ID = b.ID
and base_name = b.BADGE_BASE_NAME
and b.BADGE_blob_date > getdate()-.021
GO
The error we get is:
OLE DB provider "OraOLEDB.Oracle" for linked server "Banner" returned message "ORA-01747: invalid user.table.column, table.column, or column specification".
The syntax is correct, we can run it if the column being updated (photo) is not a blob, so we believe there is something else we have to do because of the blob. Has anybody done anything like this and know how it works? Thanks!
Tom

Given that there are no version numbers is your post I can imagine many possibilities for misconfiguration. Especially as an Oracle BLOB bears no direct size relationship to anything MS SQL could possibly support.

Interface from MS SQL Server to Oracle 8

We have a situation where we need to have Oracle PO tables updated with data from SQL Server tables. This would need to happen on a daily basis, by way of an automated interface. The folks "in the know" here have indicated that it is not feasible. Is this really that difficult to do? I am new to Oracle, but it just doesn't make sense to me that Oracle would be that difficult to deal with. Your help is greatly appreciated.

Thanks for the reply.
I am not sure what you mean by PO tables <I am referring to Purchase Order tables.
I haven't done any analysis yet - I don't even know the table names, but surely there is a PO Header table and a PO Line table, for example. What is needed is an automated interface from a separate PO system (running on SQL Server) that will update the appropriate Oracle PO tables. Apparently there is no "open interface" delivered by Oracle for these tables. So I guess my question really is: do shops typically do custom interfaces between Oracle and other systems? Surely Oracle doesn't drop support if you exercise a little intelligence and tie your systems together. My feeling is that they do, and it is simply that this particular shop prefers not to, for whtever reasons. Also, it seems to be more of a challenge given that the source data is on SQL Server, at least that is the impression I am getting. Thanks.

Transferring data from MS SQL Server to Oracle through Oracle's Stroed Procedure

Hi,
I need to access 3 tables of MS SQL Server database through oracle's Stroed procedure.
Is It possible? if yes how to do?
is there any way of accomplishing this?

Yes. Using Attunity Connect native drivers for Oracle. Attunity Connect drivers are also licensed and resold by Oracle under the name "Oracle Transparent Gateways" or "Oracle Eterogeneous Services".
The OEM Oracle driver are "light" ones. The Attunity drivers are more complete. Consult www.attunity.com

Migration from SQL server to Oracle

Hi,
Has anybody done migration from the SQL server to Oracle? If so, what manual method do you recommend? I'm a new college grad and I would like to get your expertise, if you have done this in the past.
Thanks in advance!
Sho

It is some time back, so I do not remember the specifics. Oracle gives Oracle Migration Workbench for free. You can use it to convert all SQL tables and procedures etc to oracle. It is not that difficult. If there are no stored procedures etc, you can just extract the DDL and create the tables with minor changes to the script. You might need bcp-sqlloader/trasparent gateway etc copy the data.

Convert Joins from SQL Server to Oracle

I am converting a client application's back end from using SQL Server to Oracle. This application provides a GUI that allows people to capture one or more areas of text in a text file and create database tables from these areas. It allows them to perform joins between the tables, etc. I have to convert the area that programatically creates queries behind the scenes to do these joins. Having not done much work with Oracle joins, I'm wondering if someone could show me how I could convert the sample join provided. I can probably handle the rest from there.
SQL Server Query:
SELECT
[T1].[Tk] AS [Tk],
[T1].[Tk Title] AS [Tk Title],
[T2].[Rate] AS [Rate],
[T1].[TotCurHrs] AS [TotCurHrs],
[T1].[TotCurAmt] AS [TotCurAmt],
[T1].[TotCaseHrs] AS [TotCaseHrs],
[T1].[TotCaseAmt] AS [TotCaseAmt],
[T3].[SortF] AS [SortF]
FROM
[T1] FULL JOIN [T2] ON [T1].[Tk] = [T2].[TKName]
INNER JOIN [T3] ON [T1].[Tk Title] = [T3].[EliteTitle]
)

Do as previous colleagues suggested, although you may get the problem with column names. I see at leats one of them has space in it [Tk Title]. So the question is - how you migrated table structure to Oracle? Do the column names are ABSOLUTELY the same as in MS? Then you have to replace brackets with double quotes ", because normally Oracle all identifiers tries to convert to uppercase and also space is not allowed. Only if you use quotes this is possible.

Loading data from SQL server to Oracle database

i want to create one table in oracle db from table in sql server. Table is huge it got 97,456,789 records.
I created db link (HS) in oracle database which is pointing to sql server. i can select that table from oracle thru db link.
select * from "dbo"."t1@dblink;
i fired below create table.
create table t2 nologging parallel (degree=3) as select * from "dbo"."t1@dblink;
and its taking long time.... but its running...
is there any alternate method to do this and and populate table in oracle db faster.
Please advise. thanks.

is there any alternate method to do this and and populate table in oracle db faster.Part of the performance overhead is pulling that data from SQL-Server to Oracle across the network link between them. This can be sped up by compressing the data first - and then transferring that across the network.
For example: using +bcp+ to export the data on the SQL-Server box to a CSV file, compress/zip the file, scp/sftp the file to Oracle, and then unzipping it there. Parallel and direct load processing can now be done using SQL*Loader to load the CSV into Oracle.
If this is a Linux/Unix base system, then the unzip/decompress process can be run in parallel with the SQL*Loader process by creating a pipe between the two - where the unzip process writes uncompressed data into the pipe and SQL*Loader reads and loads data as it becomes available via the pipe.
Alternatively, you can do you own PQ processing. Let's say the data is date ranged. You can create a procedure on Oracle that looks something like this:
{code}
create or replace procedure CopyDay( day date ) is
begin
insert /*+ append */ into local_tab select * from remote_tab@remotedb where col_day = day;
-- add logging info, commit, etc.
end;
{code}
You can now start 10 or more of these for different days and run it in the background using DBMS_JOB.
