I'm at the Oracle Applications Users Group Conference. It good to see what other folks are doing with big databases. I've spent most of my time in the Database SIG and at other sessions. The most impressive stuff I've see so far is during a tuning session the guy from oracle logged into the Oracle production ERP system and poked around on the cluster of Solaris E25Ks – wow. Jserv was the next issue that people seem to be having trouble with these days. Understanding the problems you can have in a multi tier environment is hard. Oracle trace files make my life hard the Hotsos profiling method was a simple way out of the mess without looking at the tracefile yourself.
