After you have configured your cell, you need to define it in the DNS global namespace
by a creating cell entry for it in DNS. To create a cell entry in DNS, an administrator
must edit a data file that contains resource records.
You also need to establish cross-cell authentication with any other cells with which you
want to communicate.
2.1.3 Establishing a Hierarchical Cell Name
Cells in a hierarchy use CDS to communicate. Consequently, if you plan to add your cell
to an existing cell hierarchy, you establish a globally unique name for it by creating a
CDS name that represents your cell in the CDS namespace of another cell, then
appending this CDS name to the global name of the cell in which you created your cell’s
CDS name. (A cell’s global name is its name starting from the /... global root prefix.) The
cell whose global name you use, and in which you have created a CDS name for your
cell, is known as your parent cell, while your cell is known as a child cell. For example,
if your parent cell’s global name is:
/.../C=US/O=ZOMBIE/OU=WOOF
and the CDS name you created for your cell is zappa, the name of your cell is:
/.../C=US/O=ZOMBIE/OU=WOOF/zappa
Note that in this situation, the parent cell’s global name may contain CDS syntax as well
as GDS or DNS syntax, depending on where it exists in the hierarchy. For example, your
parent cell’s global name could be
/.../coolco.com/sales/northeast
where /.../coolco.com is the DNS namespace portion of the name, in DNS syntax, and
/sales/northeast is the CDS namespace portion of the name, in CDS syntax. (‘‘Global’’
names are also referred to as ‘‘fully qualified’’ names. Both terms refer to names that
begin at the global root directory ....)
Note that you currently cannot use the DCE configuration program to configure a cell as
a child cell for addition into a cell hierarchy; the cell must already have been configured
before you can make it a child cell in a hierarchy. See Chapter 21 of the for instructions
on how to create a child cell.
