host_aliases.5

NAME

       host_aliases - Grid Engine host aliases file format

DESCRIPTION

       All Grid Engine 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 (through
       the Name Service Switch on systems which support it).  In some cases,
       typically clusters with hosts on multiple networks, these standard
       services cannot be setup cleanly, and Grid Engine daemons running on
       different hosts are unable to determine automatically a unique hostname
       for one or all hosts which can be used on all hosts. In such situations
       a Grid Engine host aliases file can be used to provide the 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 Grid Engine
       components using the hostname aliasing service of the communication
       library.
