Presentation Title

Can Old Roads Lead to a New Destination?


With nearly every aspect of technology changing rapidly, it is perhaps odd that we have been slow to follow suit with best practices. There is no shortage of Oracle best practices, but the big question is: "Are some of them still relevant?" This presentation will go over some of the best Oracle performance tuning practices and explain why some of them are relevant or irrelevant today. At Verisign, we have millisecond SLA's and most of the findings are implemented without impacting our response times. Some of the lessons you will learn from this session are highly radical like:

  • Using RAID-6 or RAID-5 for redo logs instead of RAID-1.
  • Cut down on your bind variables to improve performance.
  • Rebuild your indexes to improve performance.
  • Do you really need to gather data statistics? If so, how often?
  • Multiplexing control file and redo log members; how much is too much?

In short, the argument is that best practices help, but it is always good to question a "best practice". Best practices were never meant to be "one size fits all".
