15. Connectivity Software
Telnet doesn’t work - doesn’t support system i Function Keys
Rational Developer (RDI)
Client Access
Mocha (at home)
Available for download from the CS site.
Select Software for Windows ‘95 and look for MOCHA

16. ibm i Operating System Object-Based Types of Objects include:
Everything that takes up space and has a description is an object.
Types of Objects include:
User Profiles
Job Queues
Files
Programs

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

19. 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.

20. Library Lists Object used to organize data storage.
Are different for each student.
Get set back to your default when you signoff.

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

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

23. Database

24. Physical Files vs Logical Files

25. CL

26. CL Syntax
Command-name
(space) parameter

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

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

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

30. Commands that you’ll use?
Look at RDI
