QRERUN
Section: POSIX Programmer's Manual (P)
Updated: 2003
NAME
qrerun - rerun batch jobs
SYNOPSIS
qrerun job_identifier ...
DESCRIPTION
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
qrerun utility is a user-accessible batch client that requests
the rerunning of one or more batch jobs.
The qrerun utility shall rerun those batch jobs for which a
batch job_identifier is presented to the utility.
The qrerun utility shall rerun batch jobs in the order in which
their batch job_identifiers are presented to the
utility.
If the qrerun utility fails to process any batch job_identifier
successfully, the utility shall proceed to process
the remaining batch job_identifiers, if any.
The qrerun utility shall rerun batch jobs by sending a Rerun
Job Request to the batch server that manages each
batch job.
For each successfully processed batch job_identifier, the qrerun
utility shall have rerun the corresponding batch
job at the time the utility exits.
OPTIONS
None.
OPERANDS
The qrerun utility shall accept one or more operands that conform
to the syntax for a batch job_identifier (see Batch Job Identifier
).
STDIN
Not used.
INPUT FILES
None.
ENVIRONMENT VARIABLES
The following environment variables shall affect the execution of
qrerun:
- LANG
-
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.)
- LC_ALL
-
If set to a non-empty string value, override the values of all the
other internationalization variables.
- LC_CTYPE
-
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).
- LC_MESSAGES
-
Determine the locale that should be used to affect the format and
contents of diagnostic messages written to standard
error.
- LOGNAME
-
Determine the login name of the user.
ASYNCHRONOUS EVENTS
Default.
STDOUT
None.
STDERR
The standard error shall be used only for diagnostic messages.
OUTPUT FILES
None.
EXTENDED DESCRIPTION
None.
EXIT STATUS
The following exit values shall be returned:
- 0
-
Successful completion.
- >0
-
An error occurred.
CONSEQUENCES OF ERRORS
In addition to the default behavior, the qrerun 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 job_identifier does not exist on the
server. Whether or not the qrerun utility waits to output the
diagnostic message while attempting to locate the job on other
servers is implementation-defined.
The following sections are informative.
APPLICATION USAGE
None.
EXAMPLES
None.
RATIONALE
The qrerun utility allows users to cause jobs in the running
state to exit and rerun.
The qrerun utility is a new utility, vis-a-vis existing
practice, that has been defined in this volume of
IEEE Std 1003.1-2001 to correct user-perceived deficiencies in the
existing practice.
FUTURE DIRECTIONS
None.
