Planning and Conﬁguring HP DCE 1.7 3-5

Before Installing HP DCE/9000 Version 1.7

Preinstallation Planning

In general, preinstallation planning involves deciding how many cells to

conﬁgure at your site, which systems to include in each cell, and where to

run DCE services (Security, CDS, DTS, and GDA). This section gives you

some guidelines for making decisions prior to installation.

Determining Cell Boundaries

Before installation you should map the boundaries of your cell by listing

the systems that will compose your cell. You may ﬁnd it practical or

necessary to divide your site into more than one cell.

Consider the following factors when determining the cell boundaries:

• A major criterion for determining cell boundaries is to include

principals that share a common purpose, require access to a common

set of shared resources, and can share a common administrative

domain.

• Multiple cells require more administrative overhead in setting up and

maintenance.

• If you decide to create more than one cell at your site, you must

determine appropriate cell names to support intercell

communication. See “Intercell Communications” for more

information.

Intercell Communications

To implement intercell communications, you must start at least one

Global Directory Agent (GDA) daemon per cell. You can start a GDA

daemon when you conﬁgure your cell, as described in Chapter 5,

“Conﬁguring HP DCE”.

In addition, you must name your cells according to Domain Name

Service (DNS) convention. When a query cannot be resolved within a

cell, GDA passes the query to a DNS server. The following is an example

of a cell name using the DNS format:

/…/xyz.abc.com
