Operating System Software functional description

4635 LPS SOFTWARE COMPONENTS

During this process, some or all of the existing system files on the system disks are replaced with new files; user files are not affected.

·In a full sysgen, a new operating system is built on empty system disks; that is, new or used disks that have been cleared and formatted prior to sysgen.

Complete instructions for each of these sysgens are contained in the Xerox 4635 LPS System Generation Guide.

The UI Software consists of two 3.5-inch floppy diskettes (one supports the system UI Software, and one supports the UI Dialog). The Printer Software also consists of several 3.5-inch floppy diskettes. Refer to the ªSystem software functional descriptionº section for further information on the System UI Software, UI Dialog, and Printer Software.

Operating System Software functional description

The LPS OSS, or system controller, runs both background and foreground processing. All Xerox LPS systems are run by basically the same software. The OSS is delivered for installation and sysgen on 9-track magnetic tapes, and 18-track or quarter- inch cartridge tapes. The major utilities or ªtasksº run by the system controller are shown in their hierarchical relationships in the chart below.

Figure 4-1 illustrates the hierarchy of the major LPS processing tasks. Following the figure is an overview of each task.
