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.

Hi Chocobo,
I put together a Quick Guide myself

I updated it to answer your questions.
Hope that helps
Dermot.

  • Migrate Data action hanging migrating from sql server to Oracle 10g

    Hi,
    I am currently migrating a SQL Server 2005 db to Oracle 10g using SQL Developer 1.2.1. I have created the migration repository, captured the SQL Server db objects, and created the target schema. There are about 109 tables captured. During Data migration, however, the data move hangs. I have run the data move a couple of times now and it does not hang while migrating any particular table, but seems to be more to do with the length of time it is taking to migrate. Could this be an issue with SQL Server connections being lost? The SQL Server db is quite large. Row counts of 100k plus.

    Probably. There is an offline option for migrating data under the migration menu. Generate Scripts for the data move using the appropriate converted model and u can export the data to bcp export files and load it with teh generated SQL Loader scripts.

  • Migrating from SQL Server to Oracle 8i

    Hi all :),
    I am trying to migrate from SQL Server to Oracle 9i.
    I am using the Migration Workbench.
    Everything goes fine during Capturing phase, but while
    creating Oracle model the Workbench just hangs at
    "Mapping Tablespaces" for over three hours.
    (not exactly hangs in the sense that it responds to mouse
    events and I can abort the ongoing activity ...)
    What should I do ? Should I let it go on and see what
    happens.
    I follow each and every step as mentioned in the
    documentation ... but obviously I am doing something
    wrong. Any pointers ???
    However ... if I try to migrate to Personal Oracle 8 ...
    the migration goes fine from start to end ... just that
    the SQL Server triggers aren't successfully migrated.

    You may want to start by downloading the Oracle Migration Workbench. That generally does a reasonable job in moving the tables, stored procedures, etc. from SQL Server to Oracle. If your VB code is database agnostic, it should continue to work without any more intervention. Realistically, however, you'll rpobably have to at least tweak a few things that don't work the same way in the old ODBC/ OLE DB provider and the new one.
    The hard part of migrations like this is that you may need to revisit some of your architectural decisions if you want Oracle to perform well. There are plenty of things that one does in SQL Server (i.e. frequent commits) to improve performance that have the opposite affect in Oracle. Identifying and fixing these sorts of things tends to be the largest part of a migration like this. Unfortunately, I don't know of a resource that talks addresses all the possible gotchas here.

    tool but it was created only table structures not ported any data.

  • 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 !!!

  • Migration from SQL Server to Oracle 8i

    Hi,
    what are the general issues to be considered when migrating a database from SQL server to Oracle 8i.
    Is it documented on the web/ or any publication
    Samit

    What we did was to create the schema using migration work bench and then transfer the data using data junction
    The main issues that you have to handle are
    1) Data type issue, here problem comes converting chars to varchars as chars are padded and may not work in indexes, so you have to trim the afterwards, and if you have any image type data types in Sqlserver, you can use either lobs or long raw, it again depends upon your application, if you uses lobs you may have to recode your application
    2) Sql statements, Oracle cannot understand Sqlserver sql statements, so you have to convert them all. Sqlserver allows two outerjoins to a table, Oracle does not, so you have to modify your functionality
    3) Connections to the database. if you are using ODBC then use Oracle ODBC drivers and the latest ones, otherwise you may encounter memory leaks.
    These are from the top of my head, if you have any specific problem I may be able to help.
    Good luck

  • Migration from SQL 2000 to Oracle 10g

    Hi every one,
    This is the first i am posting to this forum.
    I have a problem in migration of Sql Server database to Oracle 10g.
    We use Microsoft Navision Axapta 3.0 SP4 as front end.
    and Sql Server 2000.
    All table and indexes are created in sql server by Navison only.
    My Database size is 300 GB and now we face thousands of Problem with SQL server so we decided to make a intelligent move to oracle 10g.
    As we have 1200+ users.
    The problem i am facing when i tranfer all the table to my Oracle Database it gives a error out of buffer.
    some time it gives me error about the index as few of our developer have create two indexex on one field.
    So oracle identifies that there are two indexes on one field.
    So pls help how can i solve this problem.
    I have 1234 tables.
    from
    Mohd Sufian

    Can you post the exact Oracle error you are getting? The ORA-xxxxx part is the most important for us to identify what particular problem(s) you're having.
    Is your front-end certified to use an Oracle database? Particularly if the front end is creating database objects, it needs to know how to work with whatever database it is connecting to.

  • Reading milliseconds from Sql server into oracle 10g

    Hi,
    We have a very time sensitive pressing requirements to be addressed immediately.
    We need to read the date time column from sql server 2008 into oracle 10g.
    We have a dblink established between the two servers and have tried to use sql server and sql native client 10 driver to read the dates from sql into oracle.This we are able to do very successfully.
    The issue is in reading milliseconds stored in sql server.The millisecond part comes in as 00000 from sqlserver to oracle.These milliseconds are needed to identlfy the unique records.
    For instance
    SQL SERVER Oracle
    source_id source id
    01/01/2012 6:30:35:456 01/01/2012 6:30:35:000000.
    Im issuing my query through Toad via Oracle to remote sql server using a dblink which connects using HS ODBC connection to sql server 2008(remote).
    We have no control over sql server Db as this is remote third party DB.We just have select access to their tables to bring into our own oracle DB.
    Any insight or help will be much appreciated.

    Hi,
    Could you please send the following information -
    - what version of HSODBC are you using ? Is it a 10.2 version ?
    - what is the SQL*Server datatype of the column you are reading ?
    - from Oracle could you issue -
    describe sql_server_table@hsodbc
    - what is the Oracle datatype shown for the column ?
    Could you also run your tests using SQLPLUS instead of TOAD ? We don't support TOAD and need to know if the problem also happens when using SQLPLUS, to avoid it being a TOAD problem.
    Also, 10.2 HSODBC is now desupported and you should be using the 11g Database Gateway for ODBC (DG4ODBC) which is a direct replacement for HSODBC. To use DG4ODBC your RDBMS needs to be at 10.2.0.4 or higher and DG4ODBC should be installed in a completely separate ORACLE_HOME from the existing 10.2 install.

  • 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.

  • Migration from SQL Server to Oracle database

    I have got 2 questions:
    1. We are planning to convert our OLTP sql server databases to oracle databases. I tried using SQL Developer to migrate a small sql server database to oracle database(size 5Gb). It was fine. when I tried to migrate another database(size 90G), it is taking too long. The problem with sql developer is I cannot choose and pick tables. out of 250 tables, I need to migrate abt 80 tables(size will be abt 50G). can anybody share their experiences, if any, in converting medium size sql server databases to oracle databases? any others options??
    2. I am planning to convert sql server ddl to oracle ddl. I am testing bcp out and use sql loader to import the data. Right now, I am manually creating oracle tables from sql server tables. I am using http://download.oracle.com/docs/cd/E11882_01/gateways.112/e12069/apa.htm#BABCIIDI to convert the code. Are there any other better ways to convert sql server DDL to Oracle DDL?
    Thanks in advance

    DDLs should be converted manually. Oracle is not SQL-Server.
    If you for example have the partitioning option, you should consider using partitioning and local indexes where possible. Not all tables need to be hash tables. Do you defer segment creation or not? What is the type of tablespace? Do you set percentages for free and used to manage when the data block is on the free list and how much is reserved in the data block for updating rows in that block?
    There are numerous considerations to make in terms of the physical database design.
    Using BCP and SQL*Loader sound good. SQL*Loader is fast and scalable - am using it to load up to 3.6 million rows every 60 seconds. Direct and parallel loads provide the best performance in this regard (assuming that the underlying table structure and usage supports this approach).

  • Migration from SQL Server to Oracle issue

    Hi,
    While trying to migrate SQL Server to Oracle via Standard Migration method, I got stuck at the point where it says.....
    To perform online capture, right-click the connection name in the Connections navigator and select Capture database-type (for example, Capture MySQL, Capture Microsoft Access, Capture Microsoft SQL Server, or Capture Sybase Adaptive Server).
    The problem is that, I do not see this menu Capture Microsoft SQL Server. Looks like this is a bug SQL Developer 3, which does not shows option for Capture on right clicking the non-oracle database connection. In earlier release of SQL Developer 2.1.1, I can see the option of Catture...
    Thanks,
    Gyan

    Gyan,
    You are correct. The online help screen says -
    <<<
    Online Capture
    To perform an online capture of the source database, you can have the capture performed automatically as part of the Quick Migrate option, or you can have it performed as a separate operation by right-clicking the connection name in the Connections navigator and selecting Capture product-name (for example, Capture MySQL, Capture Microsoft Access, Capture Microsoft SQL Server, or Capture Sybase Adaptive Server).
    >>>
    but this option does not show up.
    I did some testing and was able to make the capture by following these steps -
    - right click on the SQL*Server database in the Connections panel
    - choose 'Migrate to Oracle'
    - follow the menus until you get to 'Capture' screen where you should have the SQL*Server database to be migrated in the 'Selected Databases' panel
    - then choose 'Finish' from the options at bottom of the screen.
    - you should then have the capture scripts in the directory chosen earlier in the process.
    Regards,
    Mike
