Oracle to SQL Server Migration

Hi,
We have an Oracle database with 3200 tables. We want to migrate this
database tables (both structure and data) to SQL Server 2005.
What would be the best way to do that? Is there any automated migration tool
for doing that?
Is there any white paper that explains Oracle to SQL Server migration paths?
Thank you,
MaxWhy don't you post this to Oracle ng's.Imo users of db's other than
MS have more experience with other dbs than do MS users.

SSMA is a free tool.
You can access blow url.

Also, you can search microsoft.com using keword "SwisSQL".

IMHO, Max is more likely to get more/better help here with the migration
task. It won't hurt to ping Oracle forums too but I believe there is more
experience here migrating from Oracle to SQL Server than you'll find in
Oracle forums.
Hope this helps.

Blocking/concurrency implemetation is enirely different, and there are
lots of other differences. I can give you dozens of scenarios when a
"ported" application raises no syntax errors but gives different
results and/or performs very poorly.
To make long story short, be ready to rewrite at least some of your

versioning based concurrency now. So migration should be a bit smoother than
in previous SQL Server versions.

BOB! (Hi Bob) my face lit up when he told, and demonstrated the Row
versioning functionality.
Some code changes may be unavoidable, but SQL2005 can work almost exactly
like Oracle, although this does cost a little in overall performance
(currently, it seems to be about .5%) If a program is developed on SQL
only, I'd not suggest using it, but in an oracle simulation mode, it will
save alot of hassle.
Back to the original question. There are tools around which will port schema
and datastructures. I've not had too much experience with these, but it
seems that these will need checking, not only that the structure of the new
tables are the equivilant, but that all the constraints have also been
copied. In short the tools will get you started, but I doubt that they can
be trusted to complete the job.
