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.
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.
