Speaking of education, do you have your copy of the DB2 10.1/10.5 Certification Book yet? We featured the authors, Kent Collins and Mohan Saraswatipura, this past February during episodes #148 and #150. See book details on

DBI Software

During today's quick 3 minute commercial, DBI demonstrated some performance trend charts that are complete with change indicators plotted on the charts. DBI has been automatically tracking important database change events since V8.2 of DB2. Change events are plotted on trend charts so that you can see the performance consequences of any changes. Trend charts without changes are, at best, merely pretty. Do you want pretty, or do you want clear results?
