Chapter 2. Components and functions 63
z/OS mainframe based objects can be either high-level or low-level. The
high-level objects, in order of top-down hierarchy, are:
? Complex
? Machine
? LPAR
? Operating system (OS)
The low-level objects are all the objects below the Operating System, as
described in the physical hierarchy. The low-level object is defined from dynamic
discovery from the subsystems, such as automation product or others.
The high-level bulk discovery involves processing a control file that contains the
structure of each z/OS or OS/390 system. This file usually is created manually.
Our definition is provided in “ITSO_Highlevel - Sample high-level load source” on
page 564. Each line in this file contains the hierarchy of each operating system.
For example, for SC66, we used the following line:
Mainframes/ITSO Enterprise/ITSO//SC66Machine//Primary//SC66/
Mainframes is the name of the enterprise, ITSO Enterprise is its description,
ITSO is the name of the Complex, SC66Machine is the machine, Primary is the
name of the LPARs, and SC66 is the Operating System.
The high-level load uses the ITSO_Highlevel input file. The format of each line is
simply the name and description of each of the high-level object types separated
by a backslash. When we have a blank descriptions field, it is shown as a double
backslash.
To load the high-level objects into IBM Tivoli Business Systems Manager, a Korn
Shell script was executed by entering the following command at the command
prompt:
sh ASILoad_Highlevel.ksh ITSO_Highlevel.txt
The contents of ASILoad_Highlevel.ksh are shown in “ASILoad_Highlevel.ksh”
on page 560. After the load completed, the Resources view looked like
