Migrating from Oracle to SQL Server using SSMA (or other tools) over split network

Posted on 2007-08-10

I have a requirement to move some Oracle data on one server on one network into a SQL Server on another network.  I will not be able to be connected to both databases at the same time.

I see that Microsoft has a tool called SSMA that converts data between Oracle and SQL Server but I haven't seen anything on their site yet that indicates whether or not this kind of network setup can be handled.

I would need it to do the following:

1. Connect to the network that supports the source Oracle database
2. Connect to Oracle instance to generate the DDL for the tables, indexes, views etc
3. Export the data into some format (text file or some other format) that can be downloaded
4. Disconnect from network #1
5. Connect to the network where the SQL Server is located.
6. Have SSMA take the previously saved datafile and upload it to the SQL Server.

Does SSMA support this ?  I'm hoping it does because of the whole schema conversion that it talks about.

Failing this, is there another way to perform the conversion ?

Can SQL Server take comma delimited exports from Oracle (the columns in this database are VARCHAR2 or NUMBER only) and load them up?

(What I've read so far seems to indicate that if both servers are on the same network then it's relatively painless.  It's the split network thing that I'm not sure about.)

Thanks for your assistance here.

    You might look into SSIS, which is SQL Server Integration Services.  This would enable you to satisfy all of your requirements.

    A good place to start would be here:

    SSMA for Oracle is located here:

    I've never used SSMA before, but briefly reading through the docs make it seem as though it will help you as well.

    According to MS support, you can't do an offline transfer of data using SSMA.  You need to be able to be connected to both servers in order to use the tool.

    However, creating a temporary SQL Server database on a local machine, doing a backup, shipping the backup to the other network and doing the restore from there seems to be working nicely. (haven't completed all the steps but it's looking fine).

    I'll call this complete since the links do give some very useful information.
