SPARTA President’s Corner
contributed by Randy Springs
Spring is here at last, and by the time we meet in April, we will know the winner of the NCAA Final Four – with two teams from our area still dancing. Hopefully, we are making plans for a more normal vacation season amid cuts to our personal budgets to accommodate higher gas prices.
This month, we will again be holding our SPARTA meetings via Zoom format. With the removal of mask mandates in NC, we may want to consider going back to our in-person meetings if we can find an appropriate venue.
For our April meeting, join us for a presentation from KRI Security on z/OS security issues and some solutions for analyzing and protecting your z/OS environment. Invite your fellow systems programmers to join us for networking and information.
Please join your colleagues online at 7 p.m. on Tuesday, April 5, on Zoom. Watch for meeting connection information coming your way soon.

IBM z16 Day is April 5, 2022
contributed By Ed Webb
IBM is significantly upping the capabilities of the Mainframe with the announcement of the IBM z16 on Tuesday, April 5, 2022.
"[excerpts from comments heard at SHARE] IBM Z15 was very successful program; more so than z14 and earlier. The digital economy transformation speeded up during the pandemic. Executives want digital transformation.
There's potential use of artificial intelligence (AI) across business.There is a great deal of interest in Predicting and automating for increased decision velocity.
Yet we need to protect business against current and future threats by securing with a Cyber Resilient System. At the same time we must Modernize with Hybrid Cloud."

IBM z16 Day.

IBM z/OS 2.5 1Q 2022 Enhancements
contributed By Ed Webb
Along with several Continuous Delivery (CD) updates, IBM's z/OS 2.5 1Q Updates announcement also included two Statements of Direction (SOD) about upcoming offerings.
"z/OS Change Tracker
As IBM continues to provide a suite of robust tools to help system programmers manage z/OS, IBM intends to offer a new priced feature of z/OS V2.5, IBM z/OS Change Tracker. This feature is a comprehensive configuration change management tool for tracking, controlling, and managing software changes.
Learn more about this collaboration between 21st Century Software and IBM at our June SPARTA meeting when Ed Webb reports on sessions he attended at SHARE 2022 in Dallas.
System integrity monitor for z/OS
IBM intends to provide clients a system integrity monitor for z/OS that is designed to continuously monitor authorized code, including IBM and non-IBM products with privileged program calls or supervisor calls on production systems, and report on potentially vulnerable code."
Revisiting Legacy Modernization
Contributed by Ed Webb
"A 2016 study by Gartner estimated that
70 percent of an IT budget is dedicated to
just running the business. This includes
operational expenses of maintaining the
existing IT systems with no new business
services. Companies are being driven
by competition to innovate and provide
differentiating business services, but have little
of the IT budget left. As systems age, they
become more brittle and the cost of running
the business increases as a percentage of the
IT budget.
"
See Michael Benson's article in Enterprise Tech Journal 2022 Issue 1 for four methods to deal with the modernization challenge.
Humor
A New Pandemic?
contributed by Chris Blackshire
Are you sweating when you put gasoline in your car?
Are you feeling sick when you’re paying for the gasoline?
Then you have the new virus that’s going around....

Praise loudly; criticize quietly.
The only people who really listen to both sides of the argument are the neighbors.
It's not the load that breaks you down – it's the way you carry it.
