Appendix E: System/38 Configuration
Guide
System configuration is a process that specifies the machines and devices within a particular data
processing system (see Figure E-l). The Control Program Facility (CPF) is the System/38 system support
program which, in addition to providing work management and batch job functions, coordinates all
interactive processing.
Interactive processing on the System/38 takes place within the subsystem QINTER or a user-created
subsystem. QINTER (an environment supplied by IBM) supports interactive processing through all the
workstations attached to the system. All workstation devices, excluding the system console, are attached
to this subsystem. If you want the new configurations to be in effect as soon as possible, you have two
choices:
1.You may terminate the QINTER subsystem by using the TRMSBS command, and vary offline the
appropriate control unit (VRYCTLU command and any attached devices (if they previously exist).
Reverse this procedure after completing the new configuration.
2.You may power down the system using the PWRDWNSYS command, then power on the system,
setting switch 1 to 4 (IPL ABBR) and switch 2 to 0 (NORMAL) on the operator/ service panel, and
pressing the power-on switch. After signing on with the SECURITY OFFICER password, request the
configuration menu from the start control program facility prompt 2. When you are finished
configuring devices, press the CFI KEY to exit from the configuration menu.
With either of the choices (1 or 2) all interactive processing within the subsystem (exclusive of the
system console) must be terminated for the configuration process.
To avoid the necessity of shutting off the system, we will use Choice 1.
NOTE
You may change the configuration of the System/38 before or after configuration of the
LinkUp 5294. Refer to the instructions in Section 7.5 of this manual for the
configuration requirements of the LinkUp 5294.
