5. Power Systems! Developed by IBM to support medium to large scales business i means iNTEGRATION! A server designed for the on demand challenges of Web and e- business, as well as core On-line Transaction Processing (OLTP) workloads, with support for multiple operating and application environments.

11. Definitions

12. System Values Data Used to configure the power system for our business needs

13. User Profiles Each Userid has a User Profile which describes the user and their authorities Contains information such as Current Library, default output queue, password, class of user

14. “Job” A “job” is any and every piece of work on the AS/400. There are two types of jobs: –Interactive jobs –Batch jobs

15. “Interactive Jobs” A job that begins when a user signs on to the system and ends when they sign off. It is a job with interaction between the user and ibm i, similar to a conversation ( a polite conversation!). Interactive jobs run in subsystem QINTER

16. “Batch Jobs” A job that runs in the background. They are generally jobs that use a lot of resources and are lower priority than interactive jobs. Usually started by interactive jobs e.g. a program compile Batch jobs run in subsystem QBATCH

17. Work With Active Jobs Command is WRKACTJOB Shows you all the jobs that are currently running and their status.

18. Queues A queue is a line-up! A place where things wait. Examples of ibm i queues: –job queues: where batch jobs wait –message queues: where messages wait –output queues: where spool files wait to print

19. “Objects” anything in ibm i that has a name and takes up space in storage” on Unix/Windows, everything is a file on iSeries, everything is an object on Windows, files have extensions (.txt) on iSeries objects have types Common object types include: –libraries,files,job queues,programs

20. “Libraries” Library: an object whose purpose is to ‘store’ and index other objects. ie. objects are ‘stored’ in libraries. Exactly like a directory in Unix/Windows however you do not have libraries within libraries in ibm i. Example: Cindy stores all her objects in library LAURIN

21. Library Lists Similar to a windows search path Organizes libraries in order of preference

22. Files objects that store data ie. customer file: customer #, address, billing info etc. for each customer source file - special files that stores a programmer’s source code eg. Cindy stores all her source code in a source file in library LAURIN

23. File Members Source files have many ‘members’ one member contains the source code for 1 program PDM (Prog Dev Mgr) and Rational Developer give easy access to a programmer’s stuff (libs/files/mbrs)

24. What Objects Do You Have? A library which has the same name as your Userid. This is your ‘Course Library’. An Output Queue which has the same name as your userid. Your output queue is stored in your library! All objects which you create will be stored in your course library except for assignments. They will have separate libraries. WRKOBJOWN shows you all the objects you ‘own’.

25. PDM commands PDM = Program Development Manager WRKLIBPDM: work with libraries using pdm WRKOBJPDM: work with objects using pdm WRKMBRPDM: work with members using pdm

26. Commonly Used Function Keys F1 = Help F2 = Extended Help F3 = Exit F4 = Prompt F5 = Refresh Screen F9 = Retrieve Previous Command F12 = Cancel F23 = More options F24 = more function keys
