Most Active Systems ACES of 2014

One of the best parts about my job is working with Oracle ACES. They are loads of fun, interesting, and know so much more about Oracle technologies than I ever will. One of the worst parts is not having the time to give them the recognition they deserve. I won't be able to remedy that anytime soon, but I'd like to use this time at the end of the year to at least shout out to the most active Systems ACES of 2014. If you were active in 2014, please let me know so I can update this blog with your activities, as well.



Newest ACE: Brian Bream


Brian Bream is the USA's first official Systems ACE. He had tremendous depth in Solaris, SPARC servers, engineered systems, and Oracle tools, and he's keenly aware of the challenges that sysadmins face today. I've interviewed him several times for OTN Garage and Oracle OpenWorld Live. I recently wrote a blog about Brian's ACE nomination, so you can read more about him there.




Ed "Hulk" Whalen

If you search the ACE repository for Edward Whalen, he is officially listed as an expert in database management and performance. Which he is, of course. But he's also got a keen interest in Oracle Linux and Oracle VM. Here are two of the books he's written on those topics:

See Ed's Amazon page here.

Ed has also been willing to conduct and participate in interviews, plus write technical articles for OTN:

I make sure to interview him when I can, and post links to his content when I can. Ed's got deep expertise, and his community contributions and reputation are growing to the point that I expect him to be accepted as an ACE director soon.


The Prolific Alexandre Borges


Alexandre knows and teaches Oracle Solaris in depth. His real-world perspective with Solaris is priceless. In his latest book, Oracle Solaris 11 Advanced Administration Cookbook he provides in-depth coverage of every important feature in the Oracle Solaris 11 operating system. Starting with how to manage the IPS repository, make a local repository, and create your own IPS package, he explains how to handle boot environments, configure and manage ZFS frameworks, implement zones, create SMF services, and review SMF operations. Also how to configure an Automated Installer, role-based access control (RBAC) and least privileges, how to configure and administer resource manager, and finally an introduction to performance tuning.

Alexandre is also a prolific author of OTN articles. For instance, he recently finished writing an entire series on ZFS. We have published seven of them so far, with more on the way:



Seth Miller - Closet Systems ACE





Seth Miller is another one of those closet Systems ACES. Though he shows up in the ACE repository as a database ACE, he knows an awful lot about engineered systems and sysadmins:



Seth recently co-authored a book about Oracle Enterprise Manager with Kellyn Pot'Vin and Ray Smith, and had the good taste to focus on the command line:

Oracle Enterprise Manager 12c Command Line Interface

By the way, that's not Seth Miller, this is Seth Miller.








El Gaucho Diego Aguirre




When Diego is not selecting the best imported beers for his cooler, he's busy trying to keep older SPARC hardware and earlier versions of Oracle Solaris running in the data centers of his native Buenos Aires. It was also his idea to write this year-end wrap-up for Systems ACES. Gracias, Diego! Here are a few of his latest blogs. They're in Spanish, but Google will kinda sorta do a lame translation.






On My Radar

Becoming an Oracle ACE requires skill, expertise, and generosity. These four technologists have it, and I will be working with them over the coming year to help them achieve it.

Tips for Using Linux Huge Pages

Ed Whalen is the Chief Technologist at Performance Tuning Corp. He knows an awful lot about making databases run faster, including the use of Linux Huge Pages. Here are two of his very helpful resources.

Tech Article: How to Configure x86 Memory Performance for Large Databases

by Ed Whalen, Oracle ACE

Performance issues in large databases are not easy to detect using normal analysis methods such as AWR reports and OS tools such as sar, top, and iostat. And yet, if you configure your memory appropriately in x86 environments, your database can run significantly faster. This article describes you can use Linux Huge Pages to do just that.

Ed covers x86 virtual memory architecture, Linux memory management, and enabling Linux Huge Pages. See the article here.

Video Interview: What Are Linux Huge Pages?

with Ed Whalen, Oracle ACE

Ed Whalen, Oracle ACE, explains Linux huge pages, the huge performance increase they provide, and how sysadmins and DBA's need to work together to use them properly. Taped at Oracle Open World 2013.
