Unintended Consequences

I’ve found that many times in my career, a decision that was made for one reason, had unintended consequences in another area. Sometimes, these were good things and sometimes, they were not. I’ve decided to write about some of these activities in this blog. So you’ll see this title, as a recurring theme throughout my writings.

Here’s a list of the items I’m thinking about writing. Let me know what you think is most interesting to you and I’ll try to get them done earlier than the others:

  1. z/OS “stabilizes” it’s Shell and Utilities offerings at very old code levels- Rocket Software “fixes” that.  Done.
  2. OS/390 and z/OS are a better package, but they lost their sales channel. Now Solution Editions and new workloads help to drag z/OS. TCO and High Availability remain king.
  3. Apple and IBM mobile deal is pretty cool, but reminds me that Apple MacOS and z/OS are a lot alike – tons of value in a single package  – Done
  4. Use of z/OS Unix System Services introduces “surrogate” security – which might end up giving too much authority to an individual – what can be done to reduce that risk.
  5. MVS and zVM might have been considered the first cloud platform, but no one originally marketed it that way. Now, ASG’s Cloudfactory provides an Amazon Web services like front end for z/OS workloads. Done
  6. The IBM Mainframe is advertised as hacker proof, but the weakest link is not the mainframe, it’s the end user interface and people using them. What can be done to help prevent problems? Use of Intellinx zWatch is one method that a wide range of customers use to prevent human errors across platforms.
  7. Application development on the mainframe wasn’t always as simple as it was before the IBM Rational products came along and the Unit Test feature was added, which is also known as  the zPDT . This was difficult to bring to market. For the first time,  IBM separated development pricing from production pricing.
  8. Linux is ported to S/390 in December 1999.  Novell is offered the opportunity to be the first vendor on Linux on S/390. They say no.
  9. Human Resource lessons learned in a 30+ year career.
  10. High availability lessons learned. It’s not always the technology, it’s the process.
  11. Multi Level Security – probably the answer to a lot of cloud sharing problems, but no one knows what it is or does. It’s in production in some very secure locations today. Done.
  12. Thin Client Computing and usage with Mainframes
