Monitoring Oracle with oratop

Rick Miners' Oracle Blog

Intro

I recently had a situation where I was troubleshooting a system that had fallen victim to some intermittent and very high load averages. At first, there were no apparent reasons for the high load averages, so that sent me searching for some monitoring tools to help identify the issue. Besides using OSWBB and dstat, I also used the oratop utility which turns out to be a great way to get a quick overview and monitor active sessions in near real time in Oracle 11g and 12c databases. It is also RAC and ASM aware.
