ibm i  Operating System (OS/400)  Object-Based  Everything that takes up space and has a description is an object.  Types of Objects include:  User Profiles –Job Queues –Files –Programs

Traditional ibm i Data Storage Hierarchy Library Objects Members contain data - Files only

20 Library Lists Object used to organize data storage. Are different for each student. Are initially set to your default for each session you start (signon). Can be changed uniquely different for each session.

Library Lists Each job has an attached Library List Different Types of Libraries: –System: IBM Supplied –Product:Added automatically when an IBM product is used –Current: Defined by an individual user ID User ID’s default Library –User: Non-IBM Supplied Libraries Created by Business to organize programs, files, etc.

IBM i finds Objects Qualified Names Library/Object BAC344LIB/QCBLLESRC Using Library Lists! How are Library Lists sequenced?

System vs Subsystem System = ZEUS Subsystem is a logical grouping of resources

Database

Physical Files vs Logical Files

29 Integrated File System Libraries Objects Directories Stream Files Objects Folders Documents

CL Syntax Command-name (space) parameter

Keyword vs Positional Notation Keyword WRKOUTQ OUTQ(PRT01) CRTLIB LIB(MOOGK10) + TEXT(‘Cindys Library’) Positional WRKOUTQ PRT01 CRTLIB MOOGK10 *PROD ‘Cindys Library’

32 Naming of Commands Based on English! Combination of Verb and Noun CRTLIB Library Create

CL Syntax Use Menus to find the command Use F11 and Help to find the Syntax

Commands that you’ll use? Look at RDI Assignment 1
