I'll let you know in a few days... we should be starting the DMU on our test DB in a day or two. So we're right around the same place you are. the warhol: Amber E.

We have run through the entire upgrade process twice so far on our test database, and some of the tasks are taking a very long time. Specifically the following two DMU tasks are taking the longest: Populate Object Attribution Field = 43 hours Merge Loan-Related Roles = 23 hrs End to end, the entire upgrade process (scripts, updateDD, DMU, etc) is taking ~75 hours. I understand that the DMU will respond differently given your dataset, but our record set is relatively small. The Object Attribution process looks to be inserting 300k records into the ConXrefSets table, which isn't that many, but each one sets off 3 triggers, so that adds to the overhead. Still, it shouldn't be taking that long. We are on Oracle 10.2.0.4. Please let me know if you have had similar experiences and especially if you have any suggestions on how I can combat it.
