Welcome to the Observing Oracle blog

Background: Oracle/SCO Unix administrator, software security manager in the past. Developer, software consultant and Oracle DBMS troubleshooter presently. Hobby in this area: analysing behavior near point of saturation. Specialization: SQL, PL/SQL and JDBC performance tuning.


I’m posting here my thoughts and knowledge about tricky or poorly documented Oracle and Oracle related issues. I have great collection of tests that I intend to organize when time permits and upload along with a relevant message. Some random thoughts might appear from time to time in Rants category. You could safely ignore them, they are nothing to worry about.
