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



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

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 pro-
       cess 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  prece-
              dence 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  exam-
              ple, 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 writ-
              ten 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.
