This is the second article in a series about internals and performance of concurrent managers. In this post, we’ll take a look at three important settings that affect the performance of the concurrent managers: number of processes, “sleep seconds”, and “cache size”. This article might be a bit on the theoretical side, but it should provide a good understanding of how these settings actually affect the behavior and performance of concurrent managers.
There are no rules for blogging. There cannot be any, because you cannot trap the wind in your hands. It’s innovation, it’s creativity, and it’s right out of the core of the technology from the bleeding edge. This Log Buffer drips into that, and brings you some of the finest posts.
How to resolve unusual situation where Oracle was writing trace files into the user directory instead of the usual oracle diagnostic destinations.
When reviewing the performance of some queries, it is sometimes useful to review the sessions statistics for each execution of the query. I had a situation that required to look at these stats so I could see why one query would run fast and sometimes much slower. I wrote a simple wrapper ksh shell script for the query. It saves the session statistics in a table before and after the execution of the query and then prints out the statistics in a pivot report. This turned out to be very handy to me and therefore I chose to share it with the world :)

Modern commercial supercomputing in the age of Datafication is what we today call Big Data. I think a better term for it would be Data Supercomputing but the industry has already spoken so Big Data it is. The architecture shifted from environments that required massively-parallel compute-intensive number crunching to massively-parallel data-volume-intensive processing.
With real possibilities and opportunities, blogging is getting mature day by day, and so is the technology and its innovations. The combination of both becomes a dazzling medley, which is called as Log Buffer. Enjoy this week’s stunning Log Buffer #311.
