qrerun - rerun batch jobs
qrerun job_identifier ...
To rerun a batch job is to terminate the session leader of the batch job, delete any asso-
ciated 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 pre-
sented to the utility.
The qrerun utility shall rerun batch jobs in the order in which their batch job_identi-
fiers 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.
The qrerun utility shall accept one or more operands that conform to the syntax for a
batch job_identifier (see Batch Job Identifier ).
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, Inter-
nationalization 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 interna-
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 argu-
Determine the locale that should be used to affect the format and contents of diag-
nostic messages written to standard error.
Determine the login name of the user.
The standard error shall be used only for diagnostic messages.
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.
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
Batch Environment Services
