Trend Watch: Digital Business
This is the last post in a multi-part series with a focus on trends that are interesting and important, specifically in enterprise computing. I’ll continue my point-in-time analysis with a focus on digital business and how new systems of engagement (e.g., cloud and mobile devices) are changing the ways business is conducted through IT.
Getting Back to RBAC
Five years ago I was writing a lot more about RBAC—and I had a theme to "test" RBAC. I called the theme "Never look back" and I installed a few sandbox systems and ran a few "crazy" commands to see where things broke.
Why Contribute Code to the Open-Source Community?
The benefits of using open-source technologies are easy to see. Open source software helps you create and deliver solutions quickly and efficiently. It makes system administration easier. It allows a broader range of languages to be used, provides change control and adds security. Indeed, the consumption of open source technologies has a variety of advantages.
Subsystem Configuration Documentation
Some of you may have read the subsystem configuration experience reports that were written way back in 2004, which was about when V5R3 became available. The experience reports were under the related information section of the Work Management topic.
SEU Was Holding Me Back
We recently ran into a fabulous description of the value of RDi as seen from the perspective of one specific RPG developer. His name is Buck Calabro.

IBM i & RFE – Improving Future Business Value
For many years, IBM has used several methods to get customer input on the direction of the platform that has grown into today’s IBM i. The COMMON organizations in North America and Europe have been instrumental over the past two decades in providing processes for their members to submit requirements for new function to IBM, and those two organizations use their Advisory Councils (CAAC and CEAC) to advocate for the requirements that come from their members. Similarly, the Large Users Group submits requirements to IBM related to IBM i. These requirement sources, and the groups that help us work with them, have been invaluable as we’ve jointly worked to ensure that IBM i satisfies the needs of our users.
DB2 12 Catalog Availability Improvements
During the early releases of DB2, enterprises (specifically DBAs) would restrict dynamic SQL from running in their production OLTP environments. This choice stemmed primarily from the likelihood of ad hoc OLAP queries adversely impacting the performance of OLTP applications. Of course, over the next 20-plus years, this issue has been largely mitigated by the widespread adoption of dynamic SQL. Dynamic SQL continues to be a focus of DB2 development, and DB2 12 features an important enhancement in the area of catalog availability.
Running YUM on AIX
When it comes to getting open source packages onto your AIX system, there are lots of options. And while package dependencies are always a problem, Michael Perzl's solution is still sound.
