What Is System Configuration? |
|
|
System configuration is the means by which you define, in terms meaningful to the operating system, any or all of the peripheral devices attached to the computer for the input (entering) or output (storing or displaying) of data. Such devices include terminals, printers, disk drives, and tape drives. System configuration also includes the definition or modification of system parameters other than the input/output (I/O) device configuration. These parameters include system tables, the message catalog, user logging processes, system logging events, and other system resources. System configuration and generation procedures are administered and controlled through the system generator (SYSGEN) utility. SYSGEN is a program that enables a user with system manager (SM) capability to view, create, modify, and save system I/O configuration data. (A user with system supervisor (OP) capability may only view I/O configuration data.) In addition, the system manager can add, remove, and replace system boot files and system libraries by creating a system load tape (SLT). The system stores configuration data in groups and allows for multiple groups to reside on disk. SYSGEN builds on an existing configuration group to change that configuration or to create a new configuration. The new configuration data can be stored on disk or tape. This SLT tape can then be used to install an entirely new copy of the operating system or to update an existing copy.
