Distributed Network Testing: The Key to Productive Network Management Infrastructure
April 1, 2018
Network testing was a pretty straightforward process when IBM assigned me to network implementation and management in my job as a Systems Engineer. There weren’t many network components: Point-to-point or multipoint modems, a channel connection between mainframe and 3705 communication controllers with associated network interfaces (which was admittedly complex), the analog telecommunications link, a 3270 […]
ArticlesEstablishing a Network Management Infrastructure
March 1, 2018
When I first got involved in network design and implementation, network management infrastructure was unheard of—an organizational component awaiting definition. Getting a network functional was top priority, and while a manager oversaw us, she had a minimal grasp of the technology. Constructing an online, interactive, computer-based network—one that provides access to business applications the same […]

February 1, 2018
Just as with system or application tuning on a computer, network tuning is a discipline involving hardware and software, but components and methodology differ significantly. There are also commonalities, like the need to collect performance data from various sources, the need to understand interdependence and interactions involved in changing software, hardware or both. Product knowledge […]

This article focuses on CICS performance across all platforms. On the mainframe CICS is known as CICS Transaction Server (TS), but on other platforms it’s called TXSeries, with CICS Transaction Gateway providing standardized CICS interfaces and secure access. All products are developed and supported by CICS development, and interact with each other via facilities like […]
ArticlesDetermining the Electrical Grounding for Mission Critical Facilities’ Engine-Generators
November 13, 2017
The Uptime Institute LLC considers the engine-generators as a primary source of power for the mission critical facilities. Permanently installed generators for the facilities are separate power sources and are often installed as separately derived systems, which are defined in Article 100 of National Electrical Codes. This article discusses the ‘electrical grounding for the engine-generators […]
