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:

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.

Licensed Programs Licensed Internal Code Application Development Tools PDM (you have been using since the first lab) OfficeVision similar to MS-Office, but AS/400 based Communication Support Client Access Mocha Programming Languages Pascal, PL/1, Basic, RPG, C, C++, Cobol, Java, SQL, etc.

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

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!

* 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*

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

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 member Data Files: most common 1 member only exception multiple members (multi territory, multi company)

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.

Physical SECURITY Data Locked access All the digital information Damage control of processor, devices and media from fire, flood etc. Data All the digital information User Programs, O/S, Utilities, data integrity Object based / User based AS/400 uses a combination of both to ensure the MOST secure environment to operate in.

DATA SECURITY cont’d System Level - system values / levels 10 - 50 user profiles - unique and password protected controls authorities, ownership, environment, user group QSECOFR, QSECADM, QSYSOPR, QPGMR, QUSER etc… Object - access authority to object for each user authority lists for groups - *ALL *CHANGE *USE *EXCLUDE

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

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

Library Lists type *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

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

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

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

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 DSPSYSVAL QDATE
