QRERUN(P) POSIX Programmer's Manual QRERUN(P)PROLOG
This manual page is part of the POSIX Programmer's Manual. The Linux
implementation of this interface may differ (consult the corresponding
Linux manual page for details of Linux behavior), or the interface may
not be implemented on Linux.
NAMEqrerun - rerun batch jobs
SYNOPSISqrerun 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 suc‐
cessfully, 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 util‐
ity shall have rerun the corresponding batch job at the time the util‐
ity 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 qre‐
run:
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 Vari‐
ables 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_identi‐
fier 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.
