Notes on Cell Administration
Establishing Intercell Communication
In some cases it may be sufficient to point GDA at a name server that serves the zone containing cell names, and obtain hostname A (Address) 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. |
| Creating and maintaining DNS databases is a complex task that is |
NOTE | |
| 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 |
| |
| 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 |
| AT |
| 00000912C483 \ |
| Master /…/cell.xyz.com/hostname_ch \ |
