RE: Methods to Create Smaller Test DB from Production?I think the only chance you is to dupilcate the database structure (imp utility allow that if I'm right), without data, and then export table per table (imp utility in 9i has a where clause to export partially a table)
some records based on a condition.
You will have to create a script.
I don't see other solution.
So, Dennis, do you always have enough disk space on your test/dev servers to hold an entire copy of Production? For sites with VLDB, this is not possible.
(I agree that testing your backups is critical, and this is one method to do that- if you have enough disk space in Test.)

David - I disagree. I feel that your energy is better expended in creating test databases by recovering your production backup. You do test your backups, don't you? When we have created subset databases, the testing often failed to reveal problems, or the users would become frustrated with missing data. Just my 2 cents worth.

Juan,
Unfortunately, that solution requires that you have enough disk space to hold an entire copy of production, not to mention the archive logs that will be generated by deleting data.
I'm looking for clever solutions to this problem. I suppose writing your own referentially-correct ETL from Production to Test is one way. That's sort of what the DataBee product does, I think. Subsetting a production DB for test would be an excellent new feature for 10g!

You can copy the production database, the optimal You can delete records, and make this faster, and export import statistics to get performance test more accurate to reality.
I know many of you have addressed this same issue...
What is a good method to create a smaller test database from Production?
I've read about the commercial product called DataBee for doing this, but what other methods are you guys using? With all of the expertise in this list, there are bound to be some interesting solutions.
