Home -> Community -> Mailing Lists -> Oracle-L -> RE: Methods to Create Smaller Test DB from Production?
Excellent points, Dennis. The politics of getting more disk space (or
anything DBA-related) from management is always a worthy discussion.

Sometimes it is a matter of educating management. Management tends to be like everyone else, in that they don't want to spend money on stuff that isn't important. Sometimes they won't get the message the first time, so you must re-emphasize the importance at various times. I feel that I've had some success at my current site in pushing this message.
Knowing your organization's budget cycle is critical. Maybe they won't just immediately write out a check, but can be persuaded to put it into the next budget cycle. Also, it doesn't need to be "high-performance" disk. Some of the network-attached devices can dramatically lower the cost.
The other point is that if you've emphasized the vulnerability of being
unable to properly test backups, and then something goes wrong, it doesn't
look like you were simply incompetent. But the other side is if you've
clumsily made a pest of yourself, they may be inclined to use a failure to
rid themselves of a pain. Okay, I'm winding down now. Obviously this is a
topic that I feel strongly about.

You might Google this list for DataBee, because a previous discussion thread may have mentioned a free tool.

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.
