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

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  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.
