qrerun(1p)
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 useraccessible 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.
