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 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 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  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 IEEE Std 1003.1-2001  to  correct
       user-perceived deficiencies in the existing practice.

FUTURE DIRECTIONS

       None.
