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 differ (con-
       sult 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 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 international-
              ization 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 stan-
              dard 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.
