For far too long, the mainframe has been treated as an isolated citizen from a broader Application Performance Management (APM) perspective. As a result, IT has had little visibility into the impact of distributed applications’ transactions on mainframe transactions and workload, hindering the optimization of mainframe application performance. This leads to poor user experience, inefficient use of mainframe resources and a lot of wasted time and energy spent chasing down the source of performance problems…

So, you have some responsibility for the performance of your company’s mainframe. All your efforts at tuning what’s executing have been successful. There are very few “rogue” DB2 SQL statements, IMS DL/I calls or CICS transactions that keep you up at night. In fact, you sleep quite well. But there’s one problem: The mainframe is demanding more and more CPU, which is causing MIPS to rise. This trend has been attributed to an increase in volume. More volume must mean more customers, and more customers translates into higher revenues. This is good! But, wait, what if the increase in the number of customers doesn’t match the growth of MIPS? Poorly tuned applications could be the culprit. Maybe customers are accessing their data more frequently. Or, is it something else? Perhaps the business made a decision that’s driving the uptick in MIPS…

The browsers on today’s mobile smartphones are powerful and can render almost any existing Website written for the desktop browsers. However, because of their smaller display sizes and different interaction gestures (touch/swipe/pinch vs. mouse click), it’s almost always desirable to develop custom Websites targeting mobile browsers…

If you’re the CIO at a large enterprise today, you’ve perfected an acrobatic act worthy of Cirque du Soleil. Each day, you perform the impossible: making the best use of the mainframe, thousands of distributed servers, and hundreds of existing applications, all while deploying new applications and providing business services to end users non-stop…

Each day, mainframe applications support billions of online banking and mobile device-initiated e-commerce transactions across the globe. These applications are often deceivingly simple on the front-end—hit a few keys on your phone and a few days later a package arrives in the mail. We tend to take the stability and reliability of mainframe applications for granted, but the fact is these applications are highly complex. They require massive amounts of development, testing and quality assurance work within short periods of time to bring high-quality software products to market quickly…

Java application performance is critical for all companies as they shift more development to object-oriented languages. Much more than just a programming language, Java is a powerful platform with a complete set of Application Program Interfaces (APIs) for all types of distributed, complex applications. Widely popular and considered by some as the COBOL of the 21st century, Java runs almost anywhere, on top of existing platforms and is ideal for:…
