  1. IBC233 Lecture 2Updated Summer 2007

  2. Agenda • Real Estate Issues • Review • System Values • What’s ODIN doing? • Library List • Websphere • Filters • Writing a CL program

  3. Real Estate Issues • Section B – Friday’s lab is moved to T4042 • Section A – Thursday’s lab is full • Please arrive early with your student card and proof that you are in the section

  4. Review • Where will you find course notes? • Where will you find schedules, labs and assignments? • What is Client Access? • Where do you get software for free? • Who is PROFPLUTO? • What does CL stand for?

  5. System Values vs User Profile • System Values configures ODIN for everyone. • User Profile customizes ODIN’s configuration for an individual

  6. What’s ODIN Doing? • WoRK with ACTive JOBs • System vs Subsystem • Effects of an infinite loop

  7. How the iSeries finds Objects • When an object is created, it is created ‘in’ a particular library. • To access an object, the iSeries needs to know what library the object is in. • (CL) Commands prompt you for the object name and library name. • *LIBL is the default for library

  8. Library Lists • The list of Libraries through which the iSeries searches to find objects. • Similar to the DOS ‘Path’ concept • Each Job has a library list • *LIBL = library list

  9. Library Lists cont’d • A 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

  10. How do Libraries get on your Library List? • When you sign on, your library list is built from: • QSYSLIBL (system value) • QUSRLIBL (system value) • Current library from User Profile • Product libraries are added as needed by the system

  11. 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: Library Descriptions, Device Descriptions and User Profiles are always stored in library QSYS.

  12. What is CL? • What does CL stand for? • What is the IBM defined acronym?

  13. Steps to Writing a CL Program

  14. Writing a program *OUTQ WRKSPLF Compiled Listing (PGM1) Source Code QCLLESRC *FILE (PGM1) CL Compiler PGM1 *PGM Successfully Completed *MSGQ DSPMSG

  15. Some CL Commands

  16. Program Development Manager Default is a list of libraries on the library list WRKLIBPDM 12 beside a library Default is a list of objects from the last library that you looked at WRKOBJPDM 12 beside a source file Default is a list of source members (program code) that you last looked at WRKMBRPDM

  17. CL Commands • RTVJOBA – ReTrieVe JOB Attributes • Retrieves information about the environment • RTVUSRPRF – ReTrieVe USeR PRoFile • Retrieves information about the User profile that started the job • SNDPGMMSG • Sends a message to the bottom of the screen • DCL – DeCLare • CHGVAR – CHanGe a VARiable

  18. ConCATenate Strings FLDA = ‘Cindy ‘ FLDB = ‘Laurin ‘ • *CAT • Combines the strings, as they are • FLDA *CAT FLDB? • *BCAT • Combines the strings by stripping the trailing spaces off the left string and replacing it with 1 character • FLDA *BCAT FLDB? • *TCAT • Combines the string by stripping the trailing spaces off the left string. • FLDA *TCAT FLDB?

  19. Websphere IBM WebSphere Developer Studio Client for System i 6.x (WDSC) • Based on Eclipse Technology • part of IBM’s suite of products designed to enhance programmer’s productivity • PC version of PDM

  20. WebSphere Demo

  21. WebSphere - Seneca • Implementation issues • workspace stored in /temp folder

  22. Homework?
