With more than 55 percent of complex enterprise applications calling upon the mainframe to complete transactions, companies must maintain outstanding application performance to meet end-user demands, or risk extinction. The rise in use of sophisticated application performance management and fault management solutions that proactively identify problems reflects this reality. However, correctly pinpointing the cause and source of a problem is only the first step. Once Operations or QA identifies and characterizes the problem, they typically hand it over to Development to resolve…

There has always been a need to be able to quickly determine the size and complexity of a program, especially for development managers, as they consider scheduling, cost estimations, assigning projects to staff and projecting expected completion dates. The article “When Size Does Matter: The Evolution of Techniques to Gauge Program Size,” available at http://entsys.me/uuazl, discussed attempts to do this using lines of code and the Halstead Metrics. The Halstead Metrics help developers glean more insight into the complexity of a program by looking at the actual verbs and variables used in the program instead of just the lines of code…

Depending on where your shop’s modernization initiative stands, you may be extremely familiar with Eclipse-based software or you may never have heard of it. Regardless, Eclipse has come to the mainframe and is likely to change the way programmers accomplish work for years to come.
Eclipse is an open source framework built on software originally provided by IBM. It can be used to build any user interface, but is most traditionally associated with integrated development environments (IDEs). Eclipse provides the de facto Java IDE and is used by programmers worldwide. Current generation programmers have almost certainly used Eclipse, either in college, at previous jobs or in recreational programming…
