OSF DCE Administration Guide--Introduction

Chapter 4. Location of Installed DCE Files

This chapter describes the location of DCE ﬁles that are created during the installation

and conﬁguration processes. The ﬁles used by DCE are grouped in the following

locations:

• The dceshared subdirectories

• The dcelocal subdirectories

• Conventional UNIX subdirectories

Some information needs to be kept locally on a machine for reliability and to ensure that

security is maintained. For example, when you conﬁgure DCE, the ﬁle that contains the

name of your cell must be on the machine that is being conﬁgured. This ﬁle is stored in

the dcelocal subtree. Other information used in DCE can be and needs to be shared

among machines in a cell. For convenience, this information is stored in the dceshared

subtree.

The dceshared subtree is created when you use the tar command to retrieve the archived

ﬁles from the DCE tape, as described in the OSF DCE Release Notes. The dcelocal

subtree is created when you install DCE components, as described in Part 2.

The complete set of delivered DCE ﬁles, except those that are created during run time,

are stored under dceshared. The dcelocal subtree is a subset of dceshared. Files that are

required in conventional UNIX subdirectories and executables that are required in

dcelocal subdirectories can be duplicates of ﬁles and templates in the original dceshared

subtree. In some cases, ﬁles are installed into directories such as /usr/lib, /usr/bin,or

/bin for performance reasons. In other cases, symbolic links can be used from the

conventional UNIX subdirectories to dcelocal.

The following sections describe the DCE subdirectories. Appendix B provides the

directory layout for dceshared, dcelocal, and the conventional UNIX subdirectories that

are used by DCE.
