Hi All,
 
Is there any way to count queries which do all row scan of tables? I tried to get the same through dbc.DBQLExplainTbl but it didnt help.
Any help would be appreciated.
 
Thanks,

I was lucky enough to be able to attend Partners in San Diego last week.  As part of that, I did have an opportunity to speak a time or two and discussed a few performance issues.

I discussed swapping, SegIO Reads, and measuring I/O bandwidth but wasn't able to provide detail or queries, etc. at the time.

Hey,

Today in Viewpoint, one has two options for viewing of session/query information. The MyQueries portlet allows a user to see their queries even for varying Teradata logins across different Teradata systems. There is also the Query Monitor portlet that allows one to see all the queries on a system with various sorting and filtering options.

Penalty boxes have been around for years.  They come in all shapes and sizes.  Their single, focused purpose is to lock away bad queries and thereby protect good queries, while not condemning the bad ones to the ultimate penalty of being aborted.  If you’re using penalty boxes, I want to encourage you to look inside them once in a while, and open your eye
