Overview - Location of Installed DCE Files

· 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 topics provides the directory layout for dceshared, dcelocal, and the conventional UNIX subdirectories that are used by DCE.
