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 OSF DCE Administration Guide - Introduction for details.)
After you configure a cell, name it, and initialize the cell namespace, you can use the dcecp directory show 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 subtopics describe how to define and maintain a cell entry in DNS or GDS. These topics 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. Creating and Managing Hierarchical Cells in this guide describes how to define a cell in the CDS namespace of another cell.
