If IBM Corp’s own mainframe-bound operations are starting to downsize to Unix, why should anyone else hesitate a moment longer? Newton, Massachusetts-based Marcam Corp reports that its Maintenance Management object technology application software has been chosen by IBM for use in IBM plants and facilities worldwide – running on the RS/6000 with DB2/6000: seeming to sound the official IBM death knell for the mainframe and the AS/400, This announcement is an outstanding example of IBM’s commitment to use the best technology to run its business, said Lutz Hahne, vice-president and general manager, Manufacturing Industries at the company; the Maintenance Management system will be implemented in IBM research and development centres, manufacturing facilities, plants and office buildings, Marcam said.
