NAME

       host_aliases - Sun Grid Engine host aliases file format

DESCRIPTION

       All  Sun Grid Engine components use a hostname resolving service provided by the communication library to identify hosts via a unique host-
       name. 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 Sun Grid Engine 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  Sun  Grid
       Engine host aliases file can be used to provide the communication daemons with a private and consistent hostname resolution database.

       The location for the host aliases file is <sge_root>/<cell>/common/host_aliases.

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 unique hostname which will be used by all Sun Grid Engine components using the hostname aliasing service of the  communi-
       cation library.
