qrerun - rerun batch jobs
[OB BE] qrerun job_identifier...
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.
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:
- Provide a default value for the internationalization variables that are unset or null. (See XBD Internationalization Variables 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.
- Determine the login name of the user.
The standard error shall be used only for diagnostic messages.
The following exit values shall be returned:
- Successful completion.
- An error occurred.
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 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.1-2008 to correct user-perceived deficiencies in the existing practice.
The qrerun utility may be removed in a future version.

The LC_TIME and TZ entries are removed from the ENVIRONMENT VARIABLES section.
The qrerun utility is marked obsolescent.
SD5-XCU-ERN-97 is applied, updating the SYNOPSIS.
