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.

Mother, mother Oracle. I have heard you call… Wanted to sail upon your cloud (control) since 7.3.4… You’ve seen it all, you’ve seen it all… (Paraphrased from Jimmy Buffett’s, “A Pirate Looks at 40”) For a while now, Oracle Enterprise Manager (OEM) has had an application management component for E-Business Suite (EBS). However, it wasn’t…
HDFS authentication model changed in recent releases, but documentation is stale which can lead people into thinking HDFS is using very primitive authentication
Spring is a very active conference season for me. I might be going to half a dozen conferences in 3-4 months. That’s a lot of travel but I look forward to all them. The conference I’m probably looking forward the most this year is IOUG Collaborate.
Every employee at Pythian can use one workday per year to spend on activities to help the community. We call it a Pythian Volunteer Day. It’s up to the employee to decide what to use if for and when. This year I used my volunteer day to donate blood and this post is a short story about my experience.
