Unplugging and mainframe: Moving production systems to client-server
In the fall of 1994, Chevron Canada Resources (CCR) retired its mainframe computer in favour of a distributed desktop computing environment. While the accounting applications were moving to a different mainframe in San Ramone, all the production department`s applications needed to be switched to client-server. The deadline was set as September 25, 1994 to unplug the mainframe so the installation had to be complete or functionality would be lost. Only a month behind schedule, the production department`s switch to client-server was complete and the functionality of the system had been improved. Customers pushed for the project by demanding a move to PCs and workstations. The key drivers were an effective Graphical User Interface (GUI), greater availability of software and an open systems architecture. The estimated cost savings to Chevron for maintaining only one computer system in-house, as opposed to both the desktop and mainframe solutions, is one million dollars a year.
