Subj:   Re: Concurrent Loads/Deletes for Staging Table
From:   Victor Sokovin

  The deletes are performed with BTEQ scripts (no MLOAD). We do not have any secondary indexes on the Master table at this time.  

Thanks for the details. I think they confirm that deletes are using full table scan of the master table. Assuming the table is very large, TD goes for the table lock to prevent performance problems. I would experiment with the PI defined as (country_cd, customer_nbr, material_nbr).

  Thanks a lot for taking the time to respond!  

Pleasure. Please keep us posted on the progress. 30 country shops are rare and such feedback is very useful.
