The Data Store can reside on the ZENworks Primary Server or it can reside on a remote server.
All ZENworks Servers require access to the Data Store. For accessibility and reliability
purposes, you might want to consider locating the Data Store on a server cluster.
The Data Store must be either a PostgreSQL or Oracle* database. You can install the
PostgreSQL database that is included with ZENworks Linux Management or you can use an
existing Oracle 9i database or PostgreSQL database.
Depending on the number and location of the devices you want to manage with ZENworks, you
might need additional ZENworks Servers, referred to as ZENworks Secondary Servers. Secondary
Servers contain the services, package repository, and Object Store, but not the Data Store. Basically,
Secondary Servers are mirrors of the Primary Server.
The ZENworks services and Object Store are added to a Secondary Server during installation and
configuration of the ZENworks software. Packages are automatically replicated from the ZENworks
Primary Server to all Secondary Servers based upon a schedule you can control (see “
Replicating
Content in the ZENworks Management Zone ” in the Novell ZENworks 7.27.3 Linux Management
Administration Guide ). Like the Primary Server, a Secondary Server must have access to the Data
Store, whether the Data Store is located on the Primary Server or on another server.
Managed Device
A managed device is a server or workstation that you want to manage using ZENworks. The
ZENworks Agent must be installed on each device. The ZENworks Agent communicates with the
ZENworks Server to enable delivery of software packages, enforcement of configuration policies,
inventorying of hardware and software, and remote management of the device.
ZENworks Management Zone
A ZENworks Management Zone consists of one ZENworks Primary Server and one or more
managed devices. In addition, the Management Zone can include one or more ZENworks Secondary
Servers if required. The ZENworks Servers in the zone work together to manage the devices in the
zone.
If necessary, you can have more than one ZENworks Management Zone. There are two main
reasons for having multiple zones: 1) you have managed devices that are separated from your
ZENworks Servers by a slow WAN link, or 2) you need to have autonomous zones for
administrative purposes. These reasons are discussed in more detail in
Section 6, “Installing a
ZENworks Secondary Server,” on page 47 .
Information is not automatically shared between ZENworks Management Zones. However, you can
use the zlmmirror utility to copy software catalogs, bundles, or packages from one Zone’s Primary
Server to another zone’s Primary Server. The zlmmirror utility can also be used to pull catalogs,
bundles, and packages from the following servers: Dell FTP, YaST Online Updates, Red Hat
Network, Red Carpet

1.3 System Administration
The ZENworks system is administered at the Management Zone level through the ZENworks
Control Center, a task-based Web browser console.
