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

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

How the system i 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

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

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

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

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.

What is CL? What does CL stand for? What is the IBM defined acronym?
