AIX stores most of the system management information in /etc/objrepos, /usr/lib/objrepos, and /usr/share/lib/objrepos. Files (also referred to as system object classes) in these directories are adminstered by the Object Database Manager, ODM, which is a set of library routines and programs providing basic object oriented database facilities. Under most circumstances, only SMIT or the commands SMIT call (see 1.100) should be used to change the contents of the system object classes. A harmless way to look at the object database is to use odmget <Class> where <Class> is one of the files in /etc/objrepos. Experienced users can use the ODM editor, odme, to navigate the database in detail. Modifying the database should only be attempted if you know exactly what you are doing.
