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.1‐2017,  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.1‐2017, 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.1‐2017,  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.

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.1‐2017 as the natural complement to the qhold utility.

FUTURE DIRECTIONS

       The qrls utility may be removed in a future version.
