AS/400 Architecture• Object-based architecture• The Machine Interface (MI) translates

instructions from the logical machine (OS/400 and application programs) to the physical machine (the hardware).

• The MI insulates the logical machine from the physical

• There are many advantages to this:

3

Architecture cont’d

• Single level storage– main and secondary memory (RAM & disk)

are treated as a single mass

– no hardware oriented considerations (eg. Managing disk drives)

– because memory is managed by internal code, objects can be shared by different jobs.

4

Licensed ProgramsLicensed Internal Code

• Application Development Tools – PDM (you have been using since the first lab)

• OfficeVision– similar to MS-Office, but AS/400 based

• Communication SupportClient Access

Mocha• Programming Languages

– Pascal, PL/1, Basic, RPG, C, C++, Cobol, Java, SQL, etc.

5

Commonly Used Function Keys

• F1 = Help• F2 = Extended Help• F3 = Exit command

completely• F4 = Prompt• F5 = Refresh

Screen

• F9 = Retrieve Previous Command

• F12 = Cancel current level and return to previous level in command

• F23 = more options• F24 = more functions

6

Commonly Used Options on LIST type screens

• 2 = Edit• 3 = Copy• 4 = Delete• 5 = Display• 5* = Some cases

Work With• 6 = Print

• 7 = Rename• 8 = display

Description• 9 = Save• 12 = Work With• 14 = Compile /

Generate

When applicable!

7

* On the AS/400

• The * (asterisk or star) when used before a parameter value denotes a special value.Eg. *all, *libl, *curlib

• When the * is used after a parameter value, it is a wild card (just like in DOS) Eg. WRKUSRPRF DB400*

8

Using F4 and ?

• The ? is used the same way F4 is.

• Entered into a command field, it gives you the possible values for the field.

• Entered before a command, puts you in prompt mode for that command.

Eg. ?CRTLIB

9

STORAGE HIERARGY

• Library: an object whose purpose is to ‘store’ and index other objects. ie. objects are ‘stored’ in libraries.

• Files: objects that store data

• Members: Source files have many ‘members’

each source program = one memberData Files: most common 1 member

only exception multiple members (multi territory, multi company)

10

Hierarchy of Storing Objects

• When an object is created, it is stored in the library specified.

• If no library is specified, it is stored in *CURLIB (current library).

• If there is no current library, it is stored in QGPL library.

• Exception: Libraries, Device Descriptions and User Profiles are always stored in library QSYS.

System Level - system values / levels 10 - 50

user profiles - unique and password protectedcontrols authorities, ownership,environment, user groupQSECOFR, QSECADM, QSYSOPR, QPGMR, QUSER etc…

How the AS/400 finds Objects

• When an object is created, it is created ‘in’ a particular library.

• To access an object, the AS/400 needs to know what library the object is in.

• (CL) Commands prompt you for the object name and library name.

• *LIBL is the default entry for a library parameter name request

21

Qualified Name vs SIMPLE Name

• If you specify an object name and library, it is called a qualified name) e.g. Call OPS234LIB/PGM01

• When you use the object name by itself it is called a simple name and then the *LIBL is used to find the object .e.g. Call PGM01

22

Library Liststype *LIBL

• A list of Libraries, in order of importance

• Similar to the DOS ‘Path’ concept

• Each Job has it’s own library list(Can be inherited)

• It determines where a Job finds Objects when SIMPLE naming is used

23

Library Lists cont’d

• Each Library List consists of 4 parts:– System Libraries (up to 15)– Product Libraries (none, 1 or 2)– Current Library(1 only)– User Library ( up to 25)

• To view your library list - DSPLIBL

26

How / when is a Library List created?

• When you sign on (start a session), your library list is built from:– QSYSLIBL (system value)– QUSRLIBL (system value)– Current library from User Profile– Associated JOB description *JOBD initial user

list part• INHERETED from the parent job (process).• Product libraries are added as needed by the

system

27

System Values

• These values define what the default values will be.

• You can’t change them, but you can look at them.

• See page 4 of text for examples

28

System Values are used for Control and configuration attributes

System values are AS/400 attributes that allow each installation to customize the machine to the organization’s own needs and specifications.

-The categories of system values include : Date and time System control Library list values

Editing values Allocation values Security values Storage values Message and logging values
