I am trying to do a full process on a data mining structure with 2 models (decision trees and naive bayes) where the main table is small (3000+ rows). It is the MovieClick exercise in the book "Data Mining with SQL Server 2005" by Tang and MacLennan. The processing has been running for over 7 hours and has been in the status "Reading cases: 0 cases read" for almost all of that time.
Here is what "View Details" contains:
I am using the developer edition on my home pc.
What should I check to identify the problem?
Thanks!

Thank you. I see one cannot just copy and paste things into the message. The text was there when I hit Post Reply. I have since cancelled the job so cannot resend it.

Do you already know how to over come this?
Thanks

Not yet. I wish there was a way to reach the authors.

We're still waiting for you to post something that can actually be troubleshot...

I've had the same problem and solved following the instructions in this thread:

You can read the reason and detailed explanation of the problem but at the end you have to make this changes:
"
.....................
A change like below will solve the thread starvation problem:
- CoordinatorExecutionMode from -4 to -16
- ThreadPool\Process\MaxThreads from 64 to 128
- ThreadPool\Process\Concurrency from 2 to -4
Changing the CoordinatorExecutionMode from -4 to -16 allows for running 16 concurrent tasks per CPU, enough to complete the processing of the 7-nested tables model mentioned above
"
Above the mentioned ones I couldn't find a property "ThreadPool\Process\Concurrency" even in the advanced categories. But changing the other two properties solved my problem.
