Migrate MS SQL Server data to Oracle

Hi,
We need to move our data from SQL Server to Oracle, the thing is that we already have db schema for SQL Server and Oracle, so there is no need to migrate the schema(Actually our application relies on the existing schema, we don't want to change that). Is there any way to migrate the data only with the predefined db schema?
Thanks in advance

I think best for you should work to create some bcp and sql loader migration scripts, similar to the ones that SQL Developer Migration Workbench creates when moving the data in offline mode.

  • Data length problem migrating from sql server 7 to oracle 8i

    I just migrated SQL Server 7 database to Oracle 8i db and everything seemed to have ran ok except that in my newly created oracle database, the field size is doubled. For instance a field with nvarchar(4) in sql server would convert to varchar2(8). Has anyone ran into this problem and also does anyone know how to fix it? Thank you so much.

    Hi Roberto,
    You cannot use Workbench 1.2.2 to migrate from SQL Server 7 to
    Oracle 8.
    However, the good news is that we have a new verion of the
    workbench that will have a plugin that can migrate from SQL
    Server 7.0 to Oracle8.
    A beta version will be downloadable from this web-site in approx
    one week. Eventhough this version is a beta version, it has
    undergone some rigourous testing and is very close to production.

  • Error when using Oracle Migration WorkBench (Sql Server 2k to Oracle 8i)

    I'm trying to migrate a Sql Server 2k database to an Oracle 8i schema using OMWB. After using BCP to collect metadata information on the source database, I tried to capture the source data model and got a "Capture aborted" message on the progress screen (even though then it appears a dialog window reporting "0 errors and 0 warnings", funny!). Down there is the error log OMWB generated. After reading some posts, I changed some columns of the OMWB dictionary that holds the source database name, but still got the same error. If someone can enlighten me on this toppic, I'd greatly appreciated it.
    Here's the error log of OMWB:

  • Migration from SQL SERVER 2008 to Oracle 10g issues.

    Hi ,
    I'm trying to migrate from SQL Server 2008 to Oracle 10g and I end up with some issues that I wanted to ask some info about it.
    First, I was following a tutorial
    http://st-curriculum.oracle.com/obe/db/hol08/sqldev_migration/mssqlserver/migrate_microsoft_sqlserver_otn.htm
    and and in the last version of Oracle SQL developer I downloaded, I didn't find the Load Database Capture Script Output option.
    My first question is how can I either add this option or is there a new way to load the capture script ?
    Then I use the migration wizard and after following everything, I had the migration complete message from the application.
    When I tried to open my connectionss, it tells me version 11.2 is required. Does that mean that Oracle SQL developper 3 only
    do the migration for oracle 11g? And if I tried the previous versions, it doesn't support SQL server 2008.
    What do I do in this case ?
    Thanks !

    Thank you for your reply.
    After using the wizard and made the offline migration script, in the Migration projects window I made a move data to the oracle connection I previously made and after when I tried to reopen the connection, I couldn't.
    Well I didn't retry it yet to see if I'll have the same behavior but basically this is what I think I did. When I tried to open the connection I made, it says, Oracle 11.2 is required.
    Now, I just generate target from the convert model and it says migration complete but how do I test it and I do I go to oracle and see change ?
    Do I had to create a special user in SQL Server to log to it first ? How do I logon to it ?

  • Migrating From Sql Server 2005 to Oracle (Uniqueidentifier Issue)

    If i want to migrate from SQL SERVER 2005 to Oracle, How Oracle will deal with my primary key columns in almost all tables having datatype of UNIQUEIDENTIFIER ???
    is there any concept of uniqueidentifier in Oracle same as in SQL SERVER ????
    Regards

    When you migrate your SP's from SQL Server to Oracle the parser basically does 'as good a job as it can' to migrate them.
    Luckily, using SQL Developer you are able to look at the source SP and converted SP in windows next to each other and see what oracle has done to them.
    You can also paste your SQL Server code into a window and ask SQL Developer to translate it to oracle for you. Use the 'Translation Scratch Editor' on the migration menu if this is something that interests you. I was told that the parser used by the Translation Scratch Editor is different to the parser used when migrating the whole database.

  • Migration from SQL Server 2005 to Oracle 10g

    Dear buddies,
    I need to migrate my tables with data from SQL Server 2005 to Oracle 10g. How can I do it in the best possible way?
    Please guide me.
    Nith

    Nith,
    I doubt if there is one best practice that can cover all cases of migrating data from sql server to Oracle. l generally find various factors case-by-case that make me chose one approach over the other. Without considering the business case and environment specific factors, some of the things I would like to know would be: The data types of the tables columns, table sizes, number of tables and if this is a one time process or a recurring process.
    One of the easiest (some times rather pesky) process would be:
    -Dump source data (Sql Server data) into flat files, csv or any preferred format
    -Setup a set of staging set of tables in the destination DB (Oracle in your case). You can setup the stage tables to enforce data-types, value sets and even some level of integrity constraints or any data logic or what ever you would like to filter out. Load the flat file data into a set of Oracle stage tables (Sql*Loader would be a good candidate)
    -You can always move data from these stage tables to you application tables
    You can script this whole process to run as batch or on demand or how ever you would like.
    I am sure you can google and find a bunch of proprietary as well as open source tools to do the same with little to a lot of work.
    good luck!

  • Migration From SQL Server 2005 to Oracle DB through Oracle SQ Dev Problem

    Hi all,
    we are trying to do a full Migration from MS SQL Server 2005 to Oracle DB 9.2 i
    we are using Oracle SQL Developer V 1.5.3,
    the capturing of the DB and the conversion to the oracle model completed succefully
    however when we try to generate the scripts from the converted model
    the script generation hangs on a sequence and no further progress is made (the script generation pop up keeps still on a certain sequence displaying its name, and thats it )
    no error messages are displayed,
    how can we know the reason for this? or atleast find a log for whats happening...
    any suggestions?
    Thank you

    Hi,
    migrating a sequence shouldn't make a problem. I did a quick test. I created this table in SQL Server:
    create table test_seq (col1 int identity(1,1),col2 char(1))
    Then I captured the table, converted the table and generated the script. There was no problem.
    CREATE SEQUENCE succeeded.
    CREATE TABLE succeeded.
    Connected
    TRIGGER test_seq_col1_TRG Compiled.
    As you see, applying the script was also successful.
    I am using Oracle RDBMS 11g, I don't know whether this makes a difference. Do you have any 11g instance available to test it?
    Can you show me one of the sequences that are causing the hang? Is the CREATE SEQUENCE statement already in the generated script, or not? Your table is for sure more complex than my simple example.
    Regards,
    Wolfgang

  • Database Migration MS Sql Server 2008 to Oracle

    I have downloaded the latest updates for SQL Developer and am attempting to migrate my SQL Server 2008 DB to Oracle 11g. I get the following error when attempting to test my Sql Server connection:

    After attempting and following several posts, I have been unsuccessful in getting past this error - I have downloaded and placed in the specified directories the various .dll's suggested....
    Any help is of course appreciated.

    Boy do I look foolish. I told this guy that the owners of the application answer questions here... suerly he would get a reply.
    Such is the problem with "free" software. No one to blame when it doesn't work.

    Hi Naveen,
    We would like to migrate our Siebel database from Sql Server 2005 to Oracle 11g RAC. Can you suggest the best way to do that ?You will need much more which suggestions.
    You will need a Siebel professional which has done this type of migration. Migrating the Database is not a task so hard, after migrating your environment should be functional and healthy it is usually the task problematic.
    The hardware can be changed if needed. Can you please suggest the best approach ?We can recommend the minimum recommended, but this documentation already does, you need to do a analysis on your environment and ask a vendor Siebel tell the which is recommended for you and how to find the best "number" for you, in your case is very hard because everything changes.

  • Migrate sql server data to oracle

    you can drop all unwanted tables from the Oracle model before doing the data migration.
