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 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.
