QRERUN(1)                  POSIX Programmer's Manual                 QRERUN(1)



PROLOG
       This manual page is part of the POSIX Programmer's Manual.  The OS
       implementation of this interface may differ (consult the corresponding
       OS manual page for details of OS behavior), or the interface may not be
       implemented on OS.

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 Section 3.3.1, 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 POSIX.1-2017, Section 8.2, Internationalization
                 Variables 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 POSIX.1-2017 to correct user-
       perceived deficiencies in the existing practice.

FUTURE DIRECTIONS
       The qrerun utility may be removed in a future version.
