21.5.3 Deleting a Clearinghouse
Use the clearinghouse delete command to delete a clearinghouse. The command also
deletes the clearinghouse’s associated clearinghouse object entry, and all read-only
replicas from the clearinghouse.
Clearinghouse deletion can take some time to complete. CDS deletes a clearinghouse
only after successfully completing a skulk of all directories that stored read-only
replicas in the clearinghouse.
The following example command deletes the /.:/Paris2_CH clearinghouse:
dcecp> clearinghouse delete /.:/Paris2_CH
21.6 Creating and Managing Hierchical Cells
You can use CDS to connect independent cells into a hierarchical cell configuration.
In this configuration, one cell’s CDS acts as a higher-level directory service to connect
other independent cells. The cell whose CDS acts as the higher-level directory service
is known as a parent cell, while the cells connected through the parent’s CDS are
known as child cells. The cell at the top of the hierarchy must be registered in a global
directory service, such as GDS or DNS, but the cells underneath it do not need to be in
order to communicate with each other.
The next sections describe how to create a cell hierarchy, how to add cells to an
existing hierarchy, and the implications of changing a cell’s primary name when it is
part of a hierarchical cell configuration.
Note: In order to create hierarchical cells or cell name aliases, you need to use
CDS 4.0 directories.
21.6.1 Creating a Cell Hierarchy
The top-level cell in a hierarchical cell configuration must be registered in a global
directory service, either GDS or DNS. If you are creating a hierarchical cell
configuration, you need to have one cell registered in a global namespace and use it as
the topmost cell in the hierarchy. All cells underneath this cell in the hierarchy will
share this cell’s GDS or DNS name.
To register a cell in a global directory service, perform the following steps:
1. Establish a GDS or DNS name for the cell, as described in the .
2. Run the DCE configuration program to configure the cell, as described in the .
3. Define the cell in the GDS or DNS namespace, as described in Chapter 22 of this
guide.
