Just to get my hands on DTA. I followed the following process.
I setup and ran a trace in Profiler using the tuning template and ran it for some 10-15min into a table in my database. Now when I try to run DTA on the trace table I get the following error:
"Error: Workload in the input table specified : Trace01 could not be opened."
I do not understand why since I can open it up fine in Profiler. I give it a session name, choose Table, select the table from the list, and select the database to tune. If I have this in the wrong forum, I apologize
