Good Blogs to follow

September 12th, 2014
Good blogs keep popping up and other blogs fade into the back ground, so it's hard to keep track of the good stuff out there. The following is a list of blogs I have either in the past gotten a lot out of or currently do. It would be great to get comments on what the best current blogs are and then iterate on this list and keep it updated. There use to be a cool blog aggregator site called "collected.info" where I had aggregated a bunch of blogs but that site no longer seems to work and I've lost the ...

September 3rd, 2014
This article liberally uses sections from The Threat That Lies Within  by Yaniv Yehuda Databases receive much attention so they will not become THE risk factor of IT. Budgeting DRPs, backups, top of the line DBAs - and yet, they still pose a major threat. Why?

This is exactly why companies need to be agile.  They need to have better control over information, make quicker decisions, accelerate software delivery, and optimize quality control.

Greening of Storage

August 26th, 2014
By Tim Gorman I recall that the Dec 1999 or Jan 2000 issues of Nat'l Geographic magazine had a "Letters From The Editor" column that speculated, in jest, that the rate at which humans were saving back-issues of Nat'l Geographic magazine, would by the year 2100 result in the total accumulation of yellow magazines outweighing planet Earth. Anyway, that statement resonated with me, because although I change residences every few years, it has only been recently that I hadn't packed and carried my decades of accumulated Nat'l Geographic magazines with me.  Now that I'm free of them, I have no idea why ...

Can you justify your data ?

August 14th, 2014
People ask me to justify use of Delphix. I can understand. Delphix is new and often, most of my friends who are DBAs respond with "I can copy a database myself. So Delphix can copy 10 TB in 10 minutes with 0.0001 TB space. That's a neat parlor game magic trick, so what?"  Well that's missing the whole boat. The question won't be why you should use Delphix but "can you  justify working without Delphix?" Delphix is amazingly positioned at nexus of data concerns right now - the right place at the right time : Data is exploding Big Data is hyped up Data management is getting ...

July 29th, 2014
There is more and more happening in the world of visualization and visualizing Oracle performance specifically with v$active_session_history. Of these visualizations,  the one pushing the envelope the most is Marcin Przepiorowski. Marcin is responsible for writing S-ASH , ie Simulated ASH versions 2.1,2.2 and 2.3. See http://oracleprof.blogspot.com/2011/11/new-release-of-s-ash-v23.html https://github.com/pioro/orasash Here are some examples of what I have seen happening out there in the web with these visualizations grouped by the visualization tool. Gephi The first example is using Gephi. The coolest example of Gephi I’ve seen is Greg Rahn’s analysis of the voting for Oracle World mix sessions. Here is Marcin’s example using Gephi with ASH data: JIT Here are two more ...
