.SH SYNOPSIS
|

|
.LP
|
||
|
\fBqrerun\fP \fIjob_identifier\fP \fB... \fP
|
||
|
.SH DESCRIPTION
|
||
|
.LP
|
||
|
To rerun a batch job is to terminate the session leader of the batch
|
||
|
job, delete any associated checkpoint files, and return the
|
||
|
batch job to the batch queued state. A batch job is rerun by a request
|
||
|
to the batch server that manages the batch job. The
|
||
|
\fIqrerun\fP utility is a user-accessible batch client that requests
|
||
|
the rerunning of one or more batch jobs.
|
||
|
.LP
|
||
|
The \fIqrerun\fP utility shall rerun those batch jobs for which a
|
||
|
batch \fIjob_identifier\fP is presented to the utility.
|
||
|
.LP
|
||
|
The \fIqrerun\fP utility shall rerun batch jobs in the order in which
|
||
|
their batch \fIjob_identifier\fPs are presented to the
|
||
|
utility.
|
||
|
.LP
|
||
|
If the \fIqrerun\fP utility fails to process any batch \fIjob_identifier\fP
|
||
|
successfully, the utility shall proceed to process
|
||
|
the remaining batch \fIjob_identifier\fPs, if any.
|
||
|
.LP
|
||
|
The \fIqrerun\fP utility shall rerun batch jobs by sending a \fIRerun
|
||
|
Job Request\fP to the batch server that manages each
|
||
|
batch job.
|
||
|
.LP
|
||
|
For each successfully processed batch \fIjob_identifier\fP, the \fIqrerun\fP
|
||
|
utility shall have rerun the corresponding batch
|
||
|
job at the time the utility exits.
|
||
|
.SH OPTIONS
|
||
|
.LP
|
||
|
None.
|
||
|
.SH OPERANDS
|
||
|
.LP
|
||
|
The \fIqrerun\fP utility shall accept one or more operands that conform
|
||
|
to the syntax for a batch \fIjob_identifier\fP (see \fIBatch Job Identifier\fP
|
||
|
).
|
||
|
.SH STDIN
|
||
|
.LP
|
||
|
Not used.
|
||
|
.SH INPUT FILES
|
||
|
.LP
|
||
|
None.
|
||
|
.SH ENVIRONMENT VARIABLES
|
||
|
.LP
|
||
|
The following environment variables shall affect the execution of
|
||
|
\fIqrerun\fP:
|
||
|
.TP 7
|
||
|
\fILANG\fP
|
||
|
Provide a default value for the internationalization variables that
|
||
|
are unset or null. (See the Base Definitions volume of
|
||
|
IEEE\ Std\ 1003.1-2001, Section 8.2, Internationalization Variables
|
||
|
for
|
||
|
the precedence of internationalization variables used to determine
|
||
|
the values of locale categories.)
|
||
|
.TP 7
|
||
|
\fILC_ALL\fP
|
||
|
If set to a non-empty string value, override the values of all the
|
||
|
other internationalization variables.
|
||
|
.TP 7
|
||
|
\fILC_CTYPE\fP
|
||
|
Determine the locale for the interpretation of sequences of bytes
|
||
|
of text data as characters (for example, single-byte as
|
||
|
opposed to multi-byte characters in arguments).
|
||
|
.TP 7
|
||
|
\fILC_MESSAGES\fP
|
||
|
Determine the locale that should be used to affect the format and
|
||
|
contents of diagnostic messages written to standard
|
||
|
error.
|
||
|
.TP 7
|
||
|
\fILOGNAME\fP
|
||
|
Determine the login name of the user.

.SH ASYNCHRONOUS EVENTS

|

|
.LP
|
||
|
None.
|

.SH STDERR
|

.LP
|

The standard error shall be used only for diagnostic messages.
|

.SH OUTPUT FILES

.SH EXTENDED DESCRIPTION
|

|
.LP
|
||
|
None.
|
||
|
.SH EXIT STATUS
|
||
|
.LP
|
||
|
The following exit values shall be returned:
|
||
|
.TP 7
|
||
|
\ 0
|
||
|
Successful completion.
|
||
|
.TP 7
|
||
|
>0
|
||
|
An error occurred.
|
||
|
.sp
|
||
|
.SH CONSEQUENCES OF ERRORS
|
||
|
.LP
|
||
|
In addition to the default behavior, the \fIqrerun\fP utility shall
|
||
|
not be required to write a diagnostic message to standard
|
||
|
error when the error reply received from a batch server indicates
|
||
|
that the batch \fIjob_identifier\fP does not exist on the
|
||
|
server. Whether or not the \fIqrerun\fP utility waits to output the
|
||
|
diagnostic message while attempting to locate the job on other
|
||
|
servers is implementation-defined.
|
||
|

|
.SH RATIONALE
|
||
|
.LP
|
||
|
The \fIqrerun\fP utility allows users to cause jobs in the running
|
||
|
state to exit and rerun.
|
||
|
.LP
|
||
|
The \fIqrerun\fP utility is a new utility, \fIvis-a-vis\fP existing
|
||
|
practice, that has been defined in this volume of
|
||
|
IEEE\ Std\ 1003.1-2001 to correct user-perceived deficiencies in the
|
||
|
existing practice.
