NAME

qrls — release batch jobs

SYNOPSIS

qrls [−h hold_list] job_identifier...

DESCRIPTION

A batch job might have one or more holds, which prevent the batch job from executing. A
batch job from which all the holds have been removed becomes eligible for execution and is
said to have been released. A batch job hold is removed by sending a request to the batch
server that manages the batch job. The qrls utility is a user-accessible client of batch
services that requests holds be removed from one or more batch jobs.

The qrls utility shall remove one or more holds from those batch jobs for which a batch
job_identifier is presented to the utility.

The qrls utility shall remove holds from batch jobs in the order in which their batch
job_identifiers are presented to the utility.

If the qrls utility fails to process a batch job_identifier successfully, the utility
shall proceed to process the remaining batch job_identifiers, if any.

The qrls utility shall remove holds on each batch job by sending a Release Job Request to
the batch server that manages the batch job.

The qrls utility shall not exit until the holds have been removed from the batch job
corresponding to each successfully processed batch job_identifier.

OPTIONS

The qrls utility shall conform to the Base Definitions volume of POSIX.1‐2008, Section
12.2, Utility Syntax Guidelines.

The following option shall be supported by the implementation:

−h hold_list
Define the types of holds to be removed from the batch job.

The qrls −h option shall accept a value for the hold_list option-argument that
is a string of alphanumeric characters in the portable character set (see the
Base Definitions volume of POSIX.1‐2008, Section 6.1, Portable Character Set).

The qrls utility shall accept a value for the hold_list option-argument that is
a string of one or more of the characters 'u', 's', or 'o', or the single
character 'n'.

For each unique character in the hold_list option-argument, the qrls utility
shall add a value to the Hold_Types attribute of the batch job as follows, each
representing a different hold type:

u USER

s SYSTEM

o OPERATOR

If any of these characters are duplicated in the hold_list option-argument, the
duplicates shall be ignored.

An existing Hold_Types attribute can be cleared by the following hold type:

n NO_HOLD

The qrls utility shall consider it an error if any hold type other than 'n' is
combined with hold type 'n'.

Strictly conforming applications shall not repeat any of the characters 'u',
's', 'o', or 'n' within the hold_list option-argument. The qrls utility shall
permit the repetition of characters, but shall not assign additional meaning to
the repeated characters.

An implementation may define other hold types. The conformance document for an
implementation shall describe any additional hold types, how they are specified,
their internal behavior, and how they affect the behavior of the utility.

If the −h option is not presented to the qrls utility, the implementation shall
remove the USER hold in the Hold_Types attribute.

OPERANDS

The qrls 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).

STDIN

Not used.

INPUT FILES

None.

ENVIRONMENT VARIABLES

The following environment variables shall affect the execution of qrls:

LANG Provide a default value for the internationalization variables that are unset or
null. (See the Base Definitions volume of POSIX.1‐2008, 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.

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 qrls 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
qrls 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 qrls utility allows users, operators, and administrators to remove holds from jobs.

The qrls utility does not support any job selection options or wildcard arguments. Users
may acquire a list of jobs selected by attributes using the qselect utility. For example,
a user could select all of their held jobs.

The −h option allows the user to specify the type of hold that is to be removed. This
option allows for USER, SYSTEM, OPERATOR, and implementation-defined hold types. The batch
server that manages the batch job will verify whether the user is authorized to remove the
specified hold for the batch job. If more than one type of hold has been placed on the
batch job, a user may wish to remove only some of them.

Mail is not required on release because the administrator has the tools and libraries to
build this option if required.

The qrls utility is a new utility vis-a-vis existing practice; it has been defined in this
volume of POSIX.1‐2008 as the natural complement to the qhold utility.

FUTURE DIRECTIONS

The qrls utility may be removed in a future version.
