Managing Peripherals Options 2-6 will allow you to display:

each peripheral device in the selected category

the status of each device

You can also choose options to: change the status of the device change the device definition work with job(s) using the device

Changing device status The “Work with Configuration Status”

screen options let you:

Make the device unavailable (vary off)

Make the device available (vary on)

Halt communication to/from the device (hold)

Resume communication to/from the device (release)

8

Printers A printer/printing is more complicated

than a display

The “Printer” screen provides control over all the elements involved in the printing process

CPU QSpool file Print Writer

Printer screen PRINTER Printer System: S1010045 Select one of the following: 1. Work with spooled output files 2. Work with printers 3. Change job printer 4. Work with printer device status 5. Work with output queues 6. Display default system printer 7. Change default system printer 70.

Printer screen The “Printer” screen options let you:

Change the status of: the printer (opt 2 or 4) spool files (opt 1) an output queue (opt 5) the printer writer (opt 4 then option 5)

Change the default system printer

Delete spool files

End the printer writer

11

Working With Printing Components The “Work with Configuration Status”

screen for printers provides the same capabilities as for terminals: change the device status work with the job (printer writer) using the

device

Working with an output queue or printer writer will affect many spool files

Individual spool file controls include: delete assign to a different queue hold

Holding QPRINT would affect 120 spool files!

13

Working with Output Queues The screens also provide some

maintenance functions

Option 14 - Clear (CLROUTQ)

And alternative access (other than the “Device” screen) to print control functions

Option 9 - Work with Writers - provides access to printer writer functions

14

Storage Device Management Tape and Diskette device screens

provide the same capabilities as terminal and printer screens

Also provide specialized “storage functions”: Displaying storage media information Initializing the storage media Displaying the contents of storage Saving/Restoring

34

Processing Unit Resources Some system resources like

Main memory Processor time

Subsystems are groupings of these resources

In other words, creating a subsystem means allocating resources

need to be more tightly controlled

35

Processing Unit Resources Each device is then assigned to a

subsystem

Therefore, work (jobs) associated with a device is done with the allocated subsystem resources

Different types of jobs include: Interactive Batch Communication

36

Jobs Can be created many different ways:

Signing on creates an interactive job. All the work you do is considered part of that job

You can also: Submit jobs (SBMJOB) Schedule jobs to run at a particular date

and time (ADDJOBSCDE)

And, of course, there are a rich set of commands and screens to manage and control jobs

37

Jobs, Subsystems & Job Queues Just like messages and output, there is

more than meets the eye to jobs.

When work is requested the job is sent to a job queue

Job queues are tied to subsystems

Jobs can be sent to specific job queues (SBMJOB)

OR

the device’s default job queue can be used (as is done when you sign on)

Subsystems & Main Memory MM “carved up” into pools

You can display & modify the MM pool allocation with WRKSYSSTS

Pools are assigned to subsystems

You can display/modify the pool/subsystem assignment with WRKSBS

WRKSBS also provides control functions over the subsystem

Points to Remember The AS/400 has many hardware

management functions which can be accessed from the DEVICE, CMNSTS and WRKSYSSTS screens

Disk management is limited to reporting functions from CMDDSK menu

Subsystems are allocations of system resources

All work is performed as jobs within subsystems
