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)

Q Printers A printer/printing is more complicated than a display The “Printer” screen provides control over all the elements involved in the printing process Q Print Writer CPU Spool file Spool file Spool file Printer

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.

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. Copyright Janson Industries 1999

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

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

Communication Devices Standard device status screen and functions

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

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

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

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)

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

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

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

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

WRKSYSSTS

WRKSBS

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 Copyright Janson Industries 1999
