.SH NAME
host_aliases \- xxQS_NAMExx host aliases file format
.\"
.SH DESCRIPTION
All xxQS_NAMExx components use a hostname resolving service provided by
the communication library to identify hosts via a unique hostname. The
communication library itself references standard UNIX directory services
such as DNS, NIS and /etc/hosts to resolve hostnames. 
In rare cases these standard services
cannot be setup cleanly and xxQS_NAMExx communication daemons running on
different hosts are unable to automatically determine a unique hostname
for one or all hosts which can be used on all hosts. In such situations
a xxQS_NAMExx host aliases file can be used to provide the communication
daemons with a private and consistent hostname resolution database.
.PP
The location for the host aliases file is 
\fI<xxqs_name_sxx_root>/<cell>/common/host_aliases.\fP
.\"
.\"
.SH FORMAT
For each host a single line must be provided with a blank, comma or
semicolon separated list of hostname aliases. The first alias
is defined to be the \fBunique\fP hostname which will be used
by all xxQS_NAMExx components using the hostname aliasing service
of the communication library.
