Stop Run An eclectic take on the mainframe world Far From Extinction A new Web site celebrates the mainframe’s comeback BY JIM UTSLER S ome people consider the term “T-Rexxers” derogator y, referring to aging mainframe administrators, programmers and managers working on creaking mainframe systems. (“Rexx” comes from the REXX mainframe programming language.) But Denise Kalm and David Liff embrace it as a badge of honor, pointing out there’s nothing Jurassic about mainframes and the people who work on them. “People who used to think distr ibuted c om p u t i n g w a s t h e only game in town are now suddenly realizing centralized mainframe computing may be the best way to go,” notes Liff, vice president of mainframe marketing with I T management software provider CA. In fact, Kalm and Liff feel so passionate about the mainframe they launched a Web site (www.trexxers. com) where mainframers can get together to share stories, news, tech tips, related links, rants and raves, and fun, non-mainframe-related topics. “We know a lot of people in the mainframing field— including us—who look at the mainframe as a religion of sorts,” says Kalm, product marketing manager with CA. “So we thought it would be nice to create a space where these people can create a community to support each other.” This has become vital as more companies realize t he ma i n f r a me of fe r s ma ny benef it s d i st r ib uted-computing environments often lack. As Liff explains, “For the past 30 years or so, the nonmainframe world has been spinning the concept of all the wonderful things distributed systems can do. Mainframers have always known there’s a downside to distributed systems. They’re not as 20 09 reliable, they’re not as scalable and they’re not as cost effective as mainframes.” This has become apparent with mainframe-related announcements such as the IBM System z10* server. “It can do things distributed systems can only dream of,” Liff says. With the new release of this system, many organizations are taking a second look at the mainframe, recognizing it represents an evolutionary, almost Darwinian-like branch of enter pr ise computing that offers highly compelling capabilities and value. The mainframe has evolved since its inception, and many of the new technologies touted as innovations on distributed systems, such as virtualization and green computing, are nothing new to mainframers. As Liff points out, “The mainframe tends to run at more than 90-percent utilization while distributed systems typically run between 10 percent and 20 percent. The mainframe is constantly delivering business value in exchange for the energy it consumes. This makes the mainframe a truly green platform.” This is in part how the T-Rexxer Web site got its tagline: “They Lost It. We’ll Get It Back.” Companies that once ran mainframes but ditched them in favor of distributed-computing environments are now coming back to the mainframe to take advantage of all of the benefits it offers. “The pendulum has now swung back in favor of mainframers, and they’re feeling justifiably smug about it,” Kalm remarks.
