Like most of the banks, DNB has a multitude of legacy systems. Even if their functionality and consumption trends are well known by the employees in the
Application and Platform Optimization (APO) team, when new problems arise, finding the actual origin of the incident can be challenging. For this reason, since
2011, DNB has been using ITBI™ for z/OS to watch over the outsourced Mainframe and support the APO-team in their daily activities. Using ITBIaaS for z/OS, the APO team has succeeded in reducing its total MIPS consumption by 25% within one year, by identifying a long-term trend, finding its origin, and solving it over a number of steps.
“If anyone would have told me few years ago: you will find 25% of MIPS savings in your Mainframe installation I would have said: ”You are slightly optimistic here,
aren’t you?” Audun Faaberg, Performance Specialist at DNB has a long experience in optimizing Mainframe capacity, as well as finding and fixing all possible issues that can affect performance, capacity usage and costs on the Mainframe. Audun and the rest of the APO-team at DNB therefore did not expect to be able to find significant savings on their outsourced Mainframe.
”The data extracted by ITBI helped us visualize the story – says Audun Faaberg – and was therefore a fundamental element in guaranteeing the needed management support for the optimization project, ultimately leading to very impressing savings.”
”There is no doubt that this was a career-defining project for me and the rest of the APO-team. ITBI was confirmed to be a powerful tool in helping an
experienced team focus on the right things at the right time and gathering our as well as the management’s attention on what was really important to solve a serious issue and create tremendous savings for DNB.” says Audun Faaberg.
