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.
Best regards

    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.

  • Migrating users in sql server to oracle 10g

    migrating users from sqlserver to oracle10g
    what are the setps to follow for migrating users in sqlserver to oracle10g
    also
    please let me know the migration of roles and privelage in sqlserver into oracle10g
    meaning
    these are roles in sqlserver
    public
    db_owner
    db_accessadmin
    db_securityadmin
    db_ddladmin
    db_backupoperator
    db_datareader
    db_datawriter
    db_denydatareader
    db_denydatawriter
    what are equivalent role and priv in oracle

    Hi,
    We can't directly and exactly map the roles but I have mapped to similar roles below.
    In Oracle, the access mechanisms work like this:
    A user with create table privilege can create any number of tables in his own schema. He may have some quota on tablespaces, the amount of data he can use for all his tables together in that tablespace and he becomes the dbowner for his schema and schema objects.
    He can grant select, insert, update and delete privileges to any user he like.. the user who got the privileges is called a "grantee". A grantee can again grant the privileges that he received to others, provided he has been granted with "with grant option".
    A pseudo user called public, is only a place holder to say ALL ... if you grant some privileges to PUBLIC, then everyone in the database will have that privileges.
    A user with EXP_FULL_DATABASE will be able to backup the full database.
    Please refer to oracle documentation for complete details.
    public - PUBLIC
    db_owner - SCHEMA USER him self
    db_accessadmin - SCHEMA USER himself
    db_securityadmin - SCHEMA USER himself
    db_ddladmin - SCHEMA USER himself
    db_backupoperator - a role EXP_FULL_DATABASE
    db_datareader - any user who has select previliges
    db_datawriter - any user who has select, insert , update and insert privileges
    db_denydatareader - any user who do NOT have select priviliges
    db_denydatawriter - any user who do NOT have insert , update and delete privileges
    HTH

  • 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

  • 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.
    Regards
    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....

  • 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 !

  • Migration from Informix 9.4 to Oracle 10g

    We have to perform a migration from Informix 9.4 to Oracle 10g. Many tables, many data and many stored procs.
    We use the Online mode and the imports finish with any errors, but it has not recovered any stored procedures or we can't view the Informix Stored Procedures in the Source Model in the workbench.
    In the importation log appears as no found procedures, but under owner informix are all procedures.
    What we can do?

    In the 10.1.0.4 version of the workbench we create an informix user who will have all the stored procedures.
    If you want these migrated as another user you can right click on the user in the oracle model and rename it for a start.
    If this is a large migration, I would recommend the following.
    1. generate the ddl for the oracle database.
    2. for the users, that will be created, move the objects to the users that you want these in.
    3. Make sure that the privileges that a particular user has is appropriate to use the data and execute the stored procedures if necessary.
    This tool is not just a one shot deal.. It will bring the informix db over to Oracle, but you need to verify the structure and the logic of the stored procedures as being correct.

  • 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.

  • Faster way to migrate data from SQL Server to Oracle 10g

    We have to migrate data from SQL Server to Oracle 10 g.
    One particular table on SQL Server has records around 1.25 millions.
    We tried moving data using DTS package, but looks it will take hours with current speed of 300 records/minute.
    This table has TEXT column, which has XML strings stored. I am not sure, if this is the reason for slow migration.
    Would you please suggest better options to migrate it faster?
    Thanks in advance !!!

    Have you tried Migration work bench?

  • Migration from SQL server to Oracle 10g

    Hi, I am new here,
    I would like to ask how to use SQL developer MWB to migration SQL Server to Oracle?
    I have go through the doc(s) like: getting start, user's guild, etc. and have following problems
    (1), where should the SQL developer installed? in SQL Server side? Oracle side? or any PC with connection to the databases?
    (2), do I need to get some plug-in(s) for MWB to work? If yes, which plug-in do I need and where are they?
    Thank you very much.

  • Migration from sybase sql server 7 to Oracle 8i

    Hi,
    We have a very old Sybase database which contains some 2gb of data which is still being used by the users, we want to phase this out. We want to selectively export some tables and import them into our oracle 8i database. I have looked at documentation related to the migration workbench and it wont work for us because the version of sybase database is very old and I cannot find any client software either to help me to connect to the database.
    I noticed in this forum, several messages suggesting the use of bcp to export data from the sql server and then sql*loader to import the data into oracle.
    Can anybody please send me the information on bcp and how to export data using that and then how to import it in oracle. I am familiar with sql*loader but am not a expert so any help on how to define the control file etc for sql*loader would be helpful.
    Thanks

    Hi Hari,
    You will be able to get the Beta release on this site in the next
    couple of days in the 'Software' section of this page.
    We are just waiting on our web page administrators to make this
    software public.
    The amount of interest in the SQL Server 7.0 plugin is
    substantial, so we are focussing on making it production as soon
    as possible.
    Please provide feedback on the beta to [email protected]
