Имя (Name)
qrerun — rerun batch jobs
Синопсис (Synopsis)
qrerun job_identifier...
Описание (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.
Параметры (Options)
None.
Операнды (Operands)
The qrerun utility shall accept one or more operands that conform
to the syntax for a batch job_identifier (see Section 3.3.1,
Batch Job Identifier).
Стандартный ввод (Stdin)
Not used.
Входные файлы (Input files)
None.
Переменные окружения (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 POSIX.1‐2017, Section 8.2,
Internationalization Variables 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.
Асинхронные события (Asynchronous events)
Default.
Стандартный вывод (Stdout)
None.
Стандартный вывод сообщений (Stderr)
The standard error shall be used only for diagnostic messages.
Выходные файлы (Output files)
None.
Расширенное описание (Extended description)
None.
Статус выхода (Exit)
The following exit values shall be returned:
0 Successful completion.
>0 An error occurred.
Последствия ошибок (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.
Использование в приложениях (Application usage)
None.
Примеры (Examples)
None.
Обоснование (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 POSIX.1‐2017 to correct
user-perceived deficiencies in the existing practice.
Будущие направления (Future directions)
The qrerun utility may be removed in a future version.
