Requirements for hosts with multiple network interfaces

Hosts that have multiple network interfaces require additional configuration to work with Rational® ClearCase®.

If any Rational ClearCase host (client or server) has two or more network interfaces, you must create a file on that host which lists each of its host names. After you create or modify this file, you must stop and restart Rational ClearCase so that the changes take effect.

On Linux® and the UNIX® system, the file is /var/adm/rational/clearcase/config/alternate_hostnames.
On Windows®, the file is ccase-home-dir\var\config\alternate_hostnames.

For example, suppose that the NIS hosts database includes these entries for a host that runs Linux or the UNIX system:

159.0.10.16 widget sun-005 wid
159.0.16.103 widget-gte sun-105

In this case, the file alternate_hostnames on this host must contain these entries:

widget
widget-gte

Note that only the first host name in each hosts entry must be included in the file. The file must list each host name on a separate line. (You cannot include comments; all lines are significant.) If a host does not have multiple network interfaces, this file must not exist on that host.
