Preinstallation Planning

Chapter 2

Preinstallation Planning

Preinstallation planning involves deciding on how many cells to conﬁgure, which

systems to include in each cell, and where to run the DCE services (for example,

Security, CDS, and DTS). This section provides some decision making guidelines for

preinstallation planning.

Determining Cell Boundaries

Before installation, 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 and that have similar privileges.

• Multiple cells require more administrative overhead in setting up and maintenance.

• If you are creating more than one cell for your site, you must determine appropriate

cell names to support inter-cell communication.

NOTE Set the system clock to be less than 5 minutes apart for all systems that you plan to

conﬁgure in a cell. This must be done even if you do not plan to conﬁgure a DTS server.

Intercell Communications

To implement intercell communications, you must start at least one Global Directory

Agent (GDA) daemon per cell. Because this DCE/3000 release does not support GDA,

you need to ﬁnd a node in your DCE cell environment that will support a GDS server.

Check the reference pages of intercell Communications for that DCE node.
