Planning and Configuring HP-UX DCE 1.9

Chapter 4

Before Installing HP-UX DCE Version 1.9

Pre installation Planning

In general, pre installation 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 “Kernel Parameter

Recommendations” on page 33.

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

If your site is connected to the Internet and you want to obtain a unique DNS name, contact the

administrator in charge of the domain under which you want to name your cell.

For more information on cell naming, see the

OSF DCE Administration Guide - Core Services

DCE Services

This section outlines some considerations and restrictions on HP-UX DCE Version 1.9 software that will help

you map out the installation of your cell.

Client Core Services

Core Services are contained in the DCE-Core product. This product must be installed on every system in your

cell.
