12 qrls — release batch jobs
13
15 qrls [-h hold_list] job_identifier...
16
18 A batch job might have one or more holds, which prevent the batch job
19 from executing. A batch job from which all the holds have been removed
20 becomes eligible for execution and is said to have been released. A
21 batch job hold is removed by sending a request to the batch server that
22 manages the batch job. The qrls utility is a user-accessible client of
23 batch services that requests holds be removed from one or more batch
24 jobs.
25 The qrls utility shall remove one or more holds from those batch jobs
27 for which a batch job_identifier is presented to the utility.
28 The qrls utility shall remove holds from batch jobs in the order in
30 which their batch job_identifiers are presented to the utility.
31 If the qrls utility fails to process a batch job_identifier success‐
33 fully, the utility shall proceed to process the remaining batch
34 job_identifiers, if any.
35 The qrls utility shall remove holds on each batch job by sending a
37 Release Job Request to the batch server that manages the batch job.
38 The qrls utility shall not exit until the holds have been removed from
40 the batch job corresponding to each successfully processed batch
41 job_identifier.
42
44 The qrls utility shall conform to the Base Definitions volume of
45 POSIX.1‐2017, Section 12.2, Utility Syntax Guidelines.
46 The following option shall be supported by the implementation:
48 -h hold_list
50 Define the types of holds to be removed from the batch job.
51 The qrls -h option shall accept a value for the hold_list
53 option-argument that is a string of alphanumeric characters
54 in the portable character set (see the Base Definitions vol‐
55 ume of POSIX.1‐2017, Section 6.1, Portable Character Set).
56 The qrls utility shall accept a value for the hold_list
58 option-argument that is a string of one or more of the char‐
59 acters 'u', 's', or 'o', or the single character 'n'.
60 For each unique character in the hold_list option-argument,
62 the qrls utility shall add a value to the Hold_Types
63 attribute of the batch job as follows, each representing a
64 different hold type:
65 u USER
67 s SYSTEM
69 o OPERATOR
71 If any of these characters are duplicated in the hold_list
73 option-argument, the duplicates shall be ignored.
74 An existing Hold_Types attribute can be cleared by the fol‐
76 lowing hold type:
77 n NO_HOLD
79 The qrls utility shall consider it an error if any hold type
81 other than 'n' is combined with hold type 'n'.
82 Strictly conforming applications shall not repeat any of the
84 characters 'u', 's', 'o', or 'n' within the hold_list option-
85 argument. The qrls utility shall permit the repetition of
86 characters, but shall not assign additional meaning to the
87 repeated characters.
88 An implementation may define other hold types. The confor‐
90 mance document for an implementation shall describe any addi‐
91 tional hold types, how they are specified, their internal
92 behavior, and how they affect the behavior of the utility.
93 If the -h option is not presented to the qrls utility, the
95 implementation shall remove the USER hold in the Hold_Types
96 attribute.
97
99 The qrls utility shall accept one or more operands that conform to the
100 syntax for a batch job_identifier (see Section 3.3.1, Batch Job Identi‐
101 fier).
102
104 Not used.
105
107 None.
108
110 The following environment variables shall affect the execution of qrls:
111 LANG Provide a default value for the internationalization vari‐
113 ables that are unset or null. (See the Base Definitions vol‐
114 ume of POSIX.1‐2017, Section 8.2, Internationalization Vari‐
115 ables the precedence of internationalization variables used
116 to determine the values of locale categories.)
117 LC_ALL If set to a non-empty string value, override the values of
119 all the other internationalization variables.
120 LC_CTYPE Determine the locale for the interpretation of sequences of
122 bytes of text data as characters (for example, single-byte as
123 opposed to multi-byte characters in arguments).
124 LC_MESSAGES
126 Determine the locale that should be used to affect the format
127 and contents of diagnostic messages written to standard
128 error.
129 LOGNAME Determine the login name of the user.
131
133 Default.
134
136 None.
137
139 The standard error shall be used only for diagnostic messages.
140
142 None.
143
145 None.
146
148 The following exit values shall be returned:
149 0 Successful completion.
151 >0 An error occurred.
153
155 In addition to the default behavior, the qrls utility shall not be
156 required to write a diagnostic message to standard error when the error
157 reply received from a batch server indicates that the batch job_identi‐
158 fier does not exist on the server. Whether or not the qrls utility
159 waits to output the diagnostic message while attempting to locate the
160 job on other servers is implementation-defined.
161 The following sections are informative.
163
165 None.
166
168 None.
169
171 The qrls utility allows users, operators, and administrators to remove
172 holds from jobs.
173 The qrls utility does not support any job selection options or wildcard
175 arguments. Users may acquire a list of jobs selected by attributes
176 using the qselect utility. For example, a user could select all of
177 their held jobs.
178 The -h option allows the user to specify the type of hold that is to be
180 removed. This option allows for USER, SYSTEM, OPERATOR, and implementa‐
181 tion-defined hold types. The batch server that manages the batch job
182 will verify whether the user is authorized to remove the specified hold
183 for the batch job. If more than one type of hold has been placed on the
184 batch job, a user may wish to remove only some of them.
185 Mail is not required on release because the administrator has the tools
187 and libraries to build this option if required.
188 The qrls utility is a new utility vis-a-vis existing practice; it has
190 been defined in this volume of POSIX.1‐2017 as the natural complement
191 to the qhold utility.
192
194 The qrls utility may be removed in a future version.
