QHOLD(1)

NAME
qhold - hold back xxQS_NAMExx jobs from execution

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 scheduling 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 or 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 operators.

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 or the 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 operation to the array job task range specified as suffix to the job id (see the -t option to for further details on array jobs).

    The task range specifier has the form n[-m[:s]]. The range may be a single number, a simple range of the form n-m or a range with a step size s.

    Instead of job/task_id_list it is possible to use the keyword 'all' to modify the hold state for all jobs of the current user.

ENVIRONMENT VARIABLES

xxQS_NAME_Sxx_ROOT
    Specifies the location of the xxQS_NAMExx standard configuration files.

xxQS_NAME_Sxx_CELL
    If set, specifies the default xxQS_NAMExx cell. To address a xxQS_NAMExx cell qhold uses (in the order of precedence):

        The name of the cell specified in the environment variable xxQS_NAME_Sxx_CELL, if it is set.

        The name of the default cell, i.e. default.

xxQS_NAME_Sxx_DEBUG_LEVEL
    If set, specifies that debug information should be written to stderr. In addition the level of detail in which debug information is generated is defined.

xxQS_NAME_Sxx_QMASTER_PORT
    If set, specifies the tcp port on which is expected to listen for communication requests. Most installations will use a services map entry for the service "sge_qmaster" instead to define that port.
