re: ONE-TIME MIGRATION FROM ORACLE TO SQL SERVER.

I want to know the best way to migrate tables from Oracle 9i
to SQL Server '08 R2 as a cutover i.e. NO updates, no CDC (Change
Data Capture) with Attunity. Just SELECT INTO the SQL Server tables,
which DO NOT yet exist and shutdown the Oracle server for good.

I do not see any sample SSIS pkgs which do a SELECT INTO where
tables on the SQL Server do not yet exist.

Thank you,
XPXJ

Migration Assistant for Oracle would do the job. Just bing it, plenty of documentation in the net as well as in Microsoft KB.

167 pgs of instruction for . . .

"The free Microsoft SQL Server Migration Assistant (SSMA) for Oracle speeds the migration process. SSMA for Oracle V4.0 converts Oracle database objects (including stored procedures) to SQL Server database objects, loads those objects into SQL Server, migrates data from Oracle to SQL Server, and then validates the migration of code and data."

I really wasn't planning on investing a lifetime.

Have you used SSMA ? Advice ? Pitfalls ?

Thx,

Do you want to do it? or do it right?

167 pages for such a critical step seems downright small. You should be able to go through it in less than a day (and if you measure lifetimes in a day, well, that's a different issue). If it's important enough to take the database from Oracle to SQL Server, it's important enough to do it right - the first time. Otherwise, you'll end up with management questioning why did they move from Oracle to this sucky sql server product.

Am sure the issue must be sorted by now, but still, just for future reference to others. You might consider this as well:
