Notes on Cell Administration

Establishing Intercell Communication

records from that server's cache data. If the name server is frequently

used to look up hostnames, it is likely that A records for "popular" hosts

will be in cache. However, it is generally unwise to rely on a particular

resource record being found in cache — this is not a recommended or

supported conﬁguration.

Creating DNS Resource Records for a DCE Cell

Each cell that is to be accessed via GDA must have certain information

about the cell's CDS server(s) stored in DNS. DNS is a distributed,

hierarchical database that stores information as one or more "resource

records" associated with a particular domain name. The DNS resource

records are added to the DNS database, and make the cell visible to

GDA.

NOTE Creating and maintaining DNS databases is a complex task that is

beyond the scope of this document. The DNS resource record(s) for your

cell must be added to the DNS database by your local DNS

administrator, or by a person familiar with DNS and named.

The example in this section uses "absolute" (dot terminated) domain

names. This syntax, although verbose, always works. DNS also allows

names to be speciﬁed relative to the "current domain," which is

context-dependent. Contact your DNS administrator before using

relative names.

To establish a DNS resource record for a cell, do the following:

1. dce_login as the cell administrator for the cell you want to create

records for:

dce_login cell_admin

cell_admin_passwd

2. Run the cdscp show cell command. For example:

cdscp show cell /.../cell.xyz.com as dns

SHOW

CELL /.../cell.xyz.com
