|
|
.SH SYNOPSIS
|
|
qsig
|
|
[\-s\ signal]
|
|
job_identifier ...
|
|
.SH DESCRIPTION
|
|
The
|
|
.B qsig
|
|
command requests that a signal be sent to executing batch jobs.
|
|
The signal is sent to the session leader of the job.
|
|
.LP
|
|
If the
|
|
.Ar \-s
|
|
option is not specified,
|
|
.B `SIGTERM'
|
|
is sent.
|
|
The request to signal a batch job will be rejected if:
|
|
.IP \-
|
|
The user is not authorized to signal the job.
|
|
.IP \-
|
|
The job is not in the
|
|
.B running
|
|
state.
|
|
.IP \-
|
|
The requested signal is not supported by the system upon which the
|
|
job is executing.
|
|
.LP
|
|
The qsig
|
|
command sends a
|
|
.I "Signal Job"
|
|
batch request to the server which owns the job.
|
|
.SH OPTIONS
|
|
.IP "\-s signal" 15
|
|
Declares which signal is sent to the job.
|
|
.RS
|
|
.LP
|
|
The
|
|
.Ar signal
|
|
argument is either a signal name, e.g. \fBSIGKILL\fP,
|
|
the signal name without the \fBSIG\fP prefix, e.g. \fBKILL\fP,
|
|
or a unsigned signal number, e.g. \fB9\fP.
|
|
The signal name
|
|
.B SIGNULL
|
|
is allowed; the server will send the signal 0 to the job which will
|
|
have no effect on the job, but will cause an obituary to be sent if the job is
|
|
no longer executing.
|
|
Not all signal names will be recognized by qsig. If it doesn't recognize the
|
|
signal name, try issuing the signal number instead.
|
|
.LP
|
|
Two special signal names, "suspend" and "resume", are used to suspend and
|
|
resume jobs. Cray systems use the Cray-specific suspend()/resume() calls.
|
|
.LP
|
|
On non-Cray system, suspend causes a SIGTSTP to be sent to all processes in
|
|
job's top task, wait 5 seconds, and then send a SIGSTOP to all processes in all
|
|
tasks on all nodes in the job. This differs from TORQUE 2.0.0 which did not
|
|
have the ability to propogate signals to sister nodes. Resume sends a SIGCONT
|
|
to all processes in all tasks on all nodes.
|
|
.LP
|
|
When suspended, a job continues to occupy system resources but is not executing
|
|
and is not charged for walltime. The job will be listed in the "S" state.
|
|
Manager or operator privilege is required to suspend or resume a job.
|
|
.LP
|
|
Note that interactive jobs may not resume properly because the top-level
|
|
shell will background the suspended child process.
|
|
.if !\n(Pb .ig Ig
|
|
.LP
|
|
If the server receives a
|
|
.I "Signal Job"
|
|
batch request with a signal that is unsupported on the server host,
|
|
the server will reject the request.

.SH OPERANDS
|
|
The qsig command accepts one or more
|
|
.Ar job_identifier
|
|
operands of the form:
|
|
.DS
|
|
.Ty sequence_number[.server_name][@server]
|
|
.DE
|
|
.if !\n(Pb .ig Ig
|
|
See the description under "Job Identifier" in section \*(Ji in this ERS.
|
|
.Ig
|
|
.SH STANDARD ERROR
|
|
The qsig command will write a diagnostic messages to standard error for
|
|
each error occurrence.
|
|
.SH EXIT STATUS
|
|
Upon successful processing of all the operands presented to the
|
|
qsig command, the exit status will be a value of zero.
|
|
.LP
|
|
If the qsig command fails to process any operand, the
|
|
command exits with a value greater than zero.
|
|
