• Reconﬁgure the host in the new cell.

• Delete any namespace or registry entries for the host in the old cell.

2.2.3 Types of Cell Namespace Entries

The following subsections describe the different types of entries that comprise the cell

namespace. These entries are created when you follow the default conﬁguration path

described in Part 2. The , the , and the provide details about the names that the DCE

components use. The cell namespace can be divided into three major parts:

• The CDS part of the namespace

• The Security part of the namespace

• The DFS part of the namespace (the ﬁlespace)

• The dced (per host) part of the namespace

Each of the DCE services maintains its own namespace within the cell namespace. DFS

maintains its own namespace to ensure consistency among many ﬁles. The Security

Service maintains its own namespace to ensure that the DCE cell remains secure.

Clients of these two services query CDS for binding information that enables them to

ﬁnd Security or DFS servers. The points where the binding information is stored serve as

mount points in the CDS namespace for the namespaces that DFS and the Security

Service manage. This transition point between two namespaces is called a junction. The

/.:/sec directory is the junction from the CDS part to the Security part of the cell

namespace, and the /.:/fs directory is the junction from the CDS part to the DFS part of

the cell namespace.

The junction /.:/hosts/hostname/conﬁg is the junction from CDS to the dced (per host)

part of the namespace.

Figure 2-1 shows the top level of the cell namespace. In some cases the names in the cell

namespace are ﬁxed (or well known) and cannot be changed. In other cases you can

choose a different name from the one listed. For more information about which names

are well known, see the . In Figure 2-1, /.: and cell-proﬁle are well-known names.
