HOST_ALIASES(5) Sun Grid Engine File Formats HOST_ALIASES(5)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.

QRDEL(1) Sun Grid Engine User Commands QRDEL(1)NAME
qrdel - delete Sun Grid Engine Advance Reservations (AR)
SYNTAX
qrdel [-f] [-help [-u wc_user_list] wc_ar_list
DESCRIPTION
Qrdel provides a means for a user/operator/manager to delete one or more Advance Reservations (AR). A manager/operator can delete ARs
belonging to any user, while a regular user can only delete his or her own ARs. If a manager wants to delete another user's AR, the man-
ager can specify the AR id. By default, "qrdel wc_ar_name" will delete only the ARs belonging to that user. A manager is able to delete
another user's AR via "-u wc_user_list". Jobs referring to an AR tagged for deletion will also be removed. Only if all jobs referring to
an AR are removed from the Sun Grid Engine database will the AR also be removed.
Qrdel deletes ARs in the order in which the AR identifiers are presented. Find additional information concerning wc_user_list and
wc_ar_list in sge_types(1).
OPTIONS -f Force action for AR. The AR and the jobs using the AR are deleted from the Sun Grid Engine queuing system even if the sge_execd(8)
controlling the AR jobs does not respond to the delete request sent by the sge_qmaster(8).
Users which have neither Sun Grid Engine manager nor operator status can only use the -f option for their own ARs.
-help Prints a list of all options.
-u wc_user_list
Deletes only those ARs which were submitted by users specified in the list of usernames. For managers, it is possible to use qrdel
-u "*" to delete all ARs for all users. If a manager wants to delete a specific AR for a user, he has to specify the user and the AR
id. If no AR is specified, all ARs belonging to that user are deleted.
wc_ar_list
A list of AR id's that should be deleted
ENVIRONMENTAL VARIABLES
SGE_ROOT Specifies the location of the Sun Grid Engine standard configuration files.
SGE_CELL If set, specifies the default Sun Grid Engine cell. To address a Sun Grid Engine cell qrdel uses (in the order of prece-
dence):
The name of the cell specified in the environment variable SGE_CELL, if it is set.
The name of the default cell, i.e. default.
SGE_DEBUG_LEVEL
If set, specifies that debug information should be written to stderr. In addition the level of detail in which debug infor-
mation is generated is defined.
SGE_QMASTER_PORT
If set, specifies the tcp port on which the sge_qmaster(8) is expected to listen for communication requests. Most installa-
tions will use a service map entry for the service "sge_qmaster" instead of defining the port.
FILES
