Get Started With CICS Performance and Tuning
July 5, 2017
This article begins with focus on mainframe CICS but as it progresses, the focus shifts to CICS on all platforms, a progression that matches the product’s development. While techniques discussed are initially mainframe-based and oriented to CICS Transaction Server (TS), most principles and concepts apply to all processing platforms; syntax, parameters and implementation specifics may […]
ArticlesCICS TS Performance and Tuning: A Rich Tradition
June 1, 2017
It may sound geeky, but one of my favorite discussion topics—usually limited to a client’s system programmers and sometimes manager—is CICS Transaction Server (TS) performance and tuning. Sysprog is a group I’m very comfortable with, because there aren’t a lot of times I can share an acronym-laden conversation with a bunch of enthusiastic groupies passionate […]
ArticlesTokenized Encryption: The Project Nexus
May 1, 2017
The project generating this article largely involves implementation of a mainframe-based cryptographic interface oriented primarily to CICS Transaction Server, COBOL and MVS. However, these principles and concepts apply to all IT platforms. In fact, the project plan includes tasks and activities involved in converting the client’s websites using different programming languages and software to enable […]
ArticlesTokenized Encryption: Details Become Design
April 3, 2017
Once a project such as PCI compliance is approved, the first step is to hold a kickoff meeting. There are numerous reasons for a kickoff meeting: The CIO affirms the project’s importance and defines objectives, team members can acquaint themselves with each other, determine deadlines, identify potential obstacles and possible solutions, and establish requirements. But […]
ArticlesTokenized Encryption: Getting Started
March 1, 2017
When I was engaged to implement cryptography and establish payment card industry (PCI) compliance, it was for a single division of a large conglomerate where each division had its own IT department with differing software, hardware, infrastructure and performed separate implementations. Although my client had the most processing platforms and data stores to integrate, and […]
ArticlesTokenized Encryption: Connecting Docs
February 1, 2017
This third and final article on documentation examines the information necessary to support a cryptographic interface oriented to CICS Transaction Server and MVS. While the focus is on mainframe environments, the principles and concepts apply to all IT systems. Likewise, except for specific programming languages and software, this information applies to all platforms. Function […]
