Saw this blog post about how Cary Millsap learned about Oracle performance tuning and I thought it was interesting:
It is interesting because I’ve learned so much from Cary Millsap and Jeff Holt’s book and it is cool to see how Cary got to the position he is in as a well-known Oracle performance expert. I guess I’ve always found the performance tuning part of my Oracle DBA job the most interesting so it is intriguing to see someone else who feels the same way about it and how they pursued their interest and made a living doing it.
Cary’s blog post contains good advice to someone who wants to be an Oracle DBA/performance analyst. Read the Concepts manual and other relevant manuals. Read books by the performance experts. Find opportunities to work on real performance problems. Pretty much these are the steps I’ve taken, although I’ve always worked as an employee for a company instead of being a consultant. Still, working for a large company has been a good situation for me because we have a variety of systems and performance is consistently a problem that needs work.
