26 IBM Tivoli OMEGAMON XE V3.1 – Deep Dive on z/OS
Tivoli Enterprise Portal
The Tivoli Enterprise Portal, formerly called CandleNet Portal (CNP), is the user
interface into the IBM Tivoli OMEGAMON XE product set. It provides a view of
your enterprise from which you can drill down to more closely examine
components of your system environment. Its application window consists of a
Navigator that displays all systems in your enterprise where monitoring agents
are installed, and workspaces that include table and chart views of system and
application conditions. A true or raised situation causes event indicators to
appear in the navigator tree.
Tivoli Enterprise Portal offers two modes of operation: desktop and browser. In
desktop mode, the application software is installed on your system. In browser
mode, the software is downloaded to your system when you log on to Tivoli
Enterprise Portal Server and stored in the Internet Explorer cache. The Java
applet code of Tivoli Enterprise Portal is downloaded from the embedded Web
server in Tivoli Enterprise Portal Server and run on your desktop machine, thus
saving the trouble of installing and maintaining Tivoli Enterprise Portal on each
workstation that Tivoli Enterprise Portal desktop mode brings. The URL for the
browser mode client is:

Monitoring agents
Monitoring agents monitor and collect performance data from a managed
system. The agents are installed on the systems or subsystems you want to
monitor and communicate with a single Tivoli Enterprise Monitoring Server
(remote or hub). They provide data and performance information to the Tivoli
Enterprise Monitoring Server and receive instructions from the Tivoli Enterprise
Monitoring Server. They are also able to issue commands to the system or
application you are monitoring.
These monitoring agents have several names, such as: Tivoli Enterprise
Monitoring Agent, OMEGAMON monitoring agent (OMA), and Intelligent Remote
Agent (IRA). The monitoring agent can reside on z/OS systems or distributed
systems. The architecture and components of z/OS-based monitoring agents are
discussed in 2.1.3, “OMEGAMON components on z/OS” on page 26. The
distributed monitoring agent is discussed in Getting Started with IBM Tivoli
Monitoring Version 6.1, SG24-7143.
2.1.3 OMEGAMON components on z/OS
This is the principal relationship between components on z/OS:
OMEGAMON classic, IBM Tivoli OMEGAMON XE II, and OMEGAVIEW are
components that encapsulate each other and provide a degree of abstraction

that enables easier user interface with a 3270-based interface. Figure 2-3
shows overall connectivity. The user can connect with a 3270 terminal to
either the OMEGAVIEW, OMEGAMON II, or OMEGAMON classic interface.
Figure 2-3 IBM Tivoli OMEGAMON XE II vs. IBM Tivoli OMEGAMON XE Classic
An internal VTAM session is set up between the OMEGAMON II CUA
interface and OMEGAMON classic interface. The CUA component keeps
track of all of the thresholds set in the classic component, and reflects status
with status lights using input from Status Data Manager. With multi-session
VTAM support, OMEGAVIEW provides navigation into the various
OMEGAMON II products it controls.
Internally, OMEGAVIEW Session Manager connects using LU2 to
OMEGAMON II, which connects back to the SDM using LU6.2 APPC and
adds or modifies status records.
Sysplex proxy
To collect and analyze sysplex data, the data elements that are shared among
z/OS images in a sysplex environment, one Tivoli Enterprise Monitoring
Server must be designated as primary sysplex proxy. The other Tivoli
