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 RerunJob 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
The following environment variables shall affect the execution of qrerun:
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.)
If set to a non-empty string value, override the values of
all the other internationalization variables.
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).
Determine the locale that should be used to affect the
format and contents of diagnostic messages written to standard error.
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.
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.
