Application Usage

       None.

Asynchronous Events

       Default.

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.

       Thefollowingsectionsareinformative.

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 RerunJobRequest 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.

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,  Section8.2,  InternationalizationVariables 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.

Examples

       None.

Exit Status

       The following exit values shall be returned:

        0    Successful completion.

       >0    An error occurred.

Extended Description

       None.

Future Directions

       The qrerun utility may be removed in a future version.

Input Files

       None.

Name

       qrerun — rerun batch jobs

Operands

       The qrerun utility  shall  accept  one  or  more  operands  that  conform  to  the  syntax  for  a  batch
       job_identifier (see Section3.3.1, BatchJobIdentifier).

Options

       None.

Output Files

       None.

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.

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.

Stderr

       The standard error shall be used only for diagnostic messages.
