Mainframe 2.0 is CA Technologies’ far-reaching initiative to change the way you manage the mainframe. This initiative also incorporates the company’s mission to prepare a new generation to develop and maintain an extensive mainframe solution portfolio similar to those possessed by most Fortune 500- and Fortune 1000-size companies. A key component of Mainframe 2.0 is CA Mainframe University, an intensive, eight-week Mainframe Associate Engineering curriculum that turns candidates with computer science backgrounds—but little or no mainframe experience—into productive mainframe staff. CA Technologies has used this curriculum for several years to successfully train many new mainframers in the U.S. and Europe…
