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

30. Processing Unit Components
4/20/2017
Processing Unit Components
Control/status is provided for:
Communication Devices
Lines
Controllers
System Processor
Main Storage
System processor - the current AS/400 allows for 64 bit addressing.
The current processor is the new RISC processor.
Main Storage - all programs and data that the system processor is currently executing are contained in main storage.
Control Storage - Control storage is a high-speed memory area containing the most often used LIC instructions.
Input/Output Bus - is the internal circuitry that provides the high-speed transfer of data between the system processor
I/O processors - All I/O devices attached to the AS/400 are managed by the I/O processors. Each processor has separate responsibilities and tasks that are performed simultaneously and in coordination with the system processor.
Service processor - The service processor is a specialized processor that constantly monitors system performance.

31. Communication Devices
Just like the “DEVICE” screen, the
CMNSTS screen provides access to the
“Work with Configuration Status” screen.

32. Communication Devices
In this case, you specify the category
of communication device

33. Communication Devices
Standard device status
screen and functions

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: You can also:
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)

38. Jobs, Subsystems & Job Queues
Memory
Job
Queue
User
CRTCLPGM
Job
Processor
Spool file
(Compilation Report)
Output
Queue
Print
Writer
Spool file
Spool file
Printer

39. Jobs You can monitor/control the job while it’s WRKACTJOB
On the job queue (WRKJOBQ)
In the subsystem (WRKACTJOB)
WRKACTJOB
Lets you specify which subsystem
Provides standard control functions
hold
release
end
Allows you to change job attributes

40. WRKACTJOB It also shows CPU utilization for
the entire system and each active job
The function each job is executing and
the status of each job and subsystem

41. 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

42. WRKSYSSTS

43. WRKSBS

44. 4/20/2017
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
