SYNTAX
qhold [ -h {u|o|s},... ] [ -help ] [ job/task_id_list ]
qhold [ -h {u|o|s},... ] [ -help ] -u user_list
DESCRIPTION
Qhold provides a means for a user/operator/manager to place so called
holds on one or more jobs pending to be scheduled for execution. As
long as any type of hold is assigned to a job, the job is not eligible
for scheduling.
Holds can be removed with the qrls(1) or the qalter(1) command.
There are three different types of holds:
user User holds can be assigned and removed by managers, operators
and the owner of the jobs.
operator
Operator holds can be assigned and removed by managers and oper-
ators.
system System holds can be assigned and removed by managers only.
If no hold type is specified with the -h option (see below) the user
hold is assumed by default.
An alternate way to assign holds to jobs is the qsub(1) or the qal-
ter(1) command (see the -h option).
OPTIONS
-h {u|o|s},...
Assign a u(ser), o(perator) or s(system) hold or a combination
thereof to one or more jobs.
-help Prints a listing of all options.
-u username,...
Changes are only made on those jobs which were submitted by
users specified in the list of usernames. Managers are allowed
to use the qhold -u "*" command to set a hold for all jobs of
all users.
If a user uses the -u switch, the user may specify an additional
job/task_id_list.
job/task_id_list
Specified by the following form:
job_id[.task_range][,job_id[.task_range],...]
If present, the task_range restricts the effect of the qhold
SGE_CELL If set, specifies the default Univa Grid Engine cell. To
address a Univa Grid Engine cell qhold uses (in the
order of precedence):
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 writ-
ten to stderr. In addition the level of detail in which
debug information is generated is defined.
SGE_QMASTER_PORT
If set, specifies the tcp port on which sge_qmaster(8)
is expected to listen for communication requests. Most
installations will use a services map entry for the ser-
vice "sge_qmaster" instead to define that port.
