I had the opportunity to speak at the New York Oracle Users Group (http://nyoug.org/info/metro_area_user_group/Metro_Area_User_Group_Meeting_Sep_2009_Agenda.pdf) today at Hotel New Yorker. I spoke about reucing the risk during the 10g to 11g upgrade using various tools and techniques available to us as a DBA. Here is the slide deck, if you are iterested.
Some of the technologies I have described during the talk have been explained in detail on various articles I have written. Here they are:
Database Replay: http://www.oracle.com/technology/oramag/oracle/08-jan/o18dbasereplay.html
SQL Performance Analyzer (SPA):
SQL Plan Management: http://www.oracle.com/technology/oramag/oracle/09-mar/o29spm.html
As always, I highly appreciate folks coming to me after the talk and provide the feedback. Please keep the feedbacks coming, via emails, phone calls, telepathy, whatever. I really look forward to them.
