Managing Intercell Naming
4. Enter the following command to start the cdsadv process:
# cdsadv
5. Enter the following command to start the gdad process:
# gdad
To stop the GDA, enter the following command, where pid is the process identifier of the
gdad process:
# kill pid
22.3 Enabling Other Cells to Find Your Cell
The GDA is the mechanism that allows CDS clerks in your local cell to find other cells.
To make your cell accessible to others, you must create an entry for it in one of the
currently supported global naming environments. Before you do this, obtain a unique
cell name from the appropriate naming authority. (See the for details.)
After you configure a cell, name it, and initialize the cell namespace, you can use the
CDS control program (cdscp) show cell command to obtain the data you need to create
or modify the cell entry in DNS or GDS. The data in a cell entry is what the GDA passes
to CDS after looking up a cell name. CDS, in turn, uses the information to contact
servers in the cell. The following subsections describe how to define and maintain a cell
entry in DNS or GDS. These sections assume a basic familiarity with DNS and GDS; for
details, see the appropriate documentation for each global name service.
You can also define and maintain a cell entry in the CDS namespace of another cell; this
type of definition exists in a hierarchical cell configuration. Section 21.6 in this guide
describes how to define a cell in the CDS namespace of another cell.
22.3.1 Defining a Cell in the Domain Name System
Names in DNS are associated with one or more data structures called resource records.
The resource records are stored in a data file whose name and location are
implementation specific. To create a cell entry, you must edit the data file and create two
resource records for each CDS server that maintains a replica of the cell namespace root.
The first resource record, whose type can be AFSDB or MX, contains the host name of
the system where the CDS server resides. You can use MX as an alternative to using
AFSDB. The second record, of type TXT, contains the following information about the
replica of the root directory that the server maintains:
• The UUID of the cell namespace, in hexadecimal notation
