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_identifier s 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_identifier s,
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 XBD
V1_chap12(7) .
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-hoption shall accept a value for the hold_list option-argument that is a string of alphanumeric characters in the portable character set (see XBD V1_chap06(7) ).The
qrlsutility 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
qrlsutility shall add a value to the Hold_Types attribute of the batch job as follows, each representing a different hold type: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
qrlsutility 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. Theqrlsutility 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
-hoption is not presented to theqrlsutility, 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 V3_chap03(1) ).
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 XBD 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:
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.
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(1) 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(1) utility.
FUTURE DIRECTIONS
The qrls utility may be removed in a
future version.
