13 qrls — release batch jobs
14
16 qrls [−h hold_list] job_identifier...
17
19 A batch job might have one or more holds, which prevent the batch job
20 from executing. A batch job from which all the holds have been removed
21 becomes eligible for execution and is said to have been released. A
22 batch job hold is removed by sending a request to the batch server that
23 manages the batch job. The qrls utility is a user-accessible client of
24 batch services that requests holds be removed from one or more batch
25 jobs.
26 The qrls utility shall remove one or more holds from those batch jobs
28 for which a batch job_identifier is presented to the utility.
29 The qrls utility shall remove holds from batch jobs in the order in
31 which their batch job_identifiers are presented to the utility.
32 If the qrls utility fails to process a batch job_identifier success‐
34 fully, the utility shall proceed to process the remaining batch
35 job_identifiers, if any.
36 The qrls utility shall remove holds on each batch job by sending a
38 Release Job Request to the batch server that manages the batch job.
39 The qrls utility shall not exit until the holds have been removed from
41 the batch job corresponding to each successfully processed batch
42 job_identifier.
43
45 The qrls utility shall conform to the Base Definitions volume of
46 POSIX.1‐2008, Section 12.2, Utility Syntax Guidelines.
47 The following option shall be supported by the implementation:
49 −h hold_list
51 Define the types of holds to be removed from the batch job.
52 The qrls −h option shall accept a value for the hold_list
54 option-argument that is a string of alphanumeric characters
55 in the portable character set (see the Base Definitions vol‐
56 ume of POSIX.1‐2008, Section 6.1, Portable Character Set).
57 The qrls utility shall accept a value for the hold_list
59 option-argument that is a string of one or more of the char‐
60 acters 'u', 's', or 'o', or the single character 'n'.
61 For each unique character in the hold_list option-argument,
63 the qrls utility shall add a value to the Hold_Types
64 attribute of the batch job as follows, each representing a
65 different hold type:
66 u USER
68 s SYSTEM
70 o OPERATOR
72 If any of these characters are duplicated in the hold_list
74 option-argument, the duplicates shall be ignored.
75 An existing Hold_Types attribute can be cleared by the fol‐
77 lowing hold type:
78 n NO_HOLD
80 The qrls utility shall consider it an error if any hold type
82 other than 'n' is combined with hold type 'n'.
83 Strictly conforming applications shall not repeat any of the
85 characters 'u', 's', 'o', or 'n' within the hold_list option-
86 argument. The qrls utility shall permit the repetition of
87 characters, but shall not assign additional meaning to the
88 repeated characters.
89 An implementation may define other hold types. The confor‐
91 mance document for an implementation shall describe any addi‐
92 tional hold types, how they are specified, their internal
93 behavior, and how they affect the behavior of the utility.
94 If the −h option is not presented to the qrls utility, the
96 implementation shall remove the USER hold in the Hold_Types
97 attribute.
98
100 The qrls utility shall accept one or more operands that conform to the
101 syntax for a batch job_identifier (see Section 3.3.1, Batch Job Identi‐
102 fier).
103
105 Not used.
106
108 None.
109
111 The following environment variables shall affect the execution of qrls:
112 LANG Provide a default value for the internationalization vari‐
114 ables that are unset or null. (See the Base Definitions vol‐
115 ume of POSIX.1‐2008, Section 8.2, Internationalization Vari‐
116 ables the precedence of internationalization variables used
117 to determine the values of locale categories.)
118 LC_ALL If set to a non-empty string value, override the values of
120 all the other internationalization variables.
121 LC_CTYPE Determine the locale for the interpretation of sequences of
123 bytes of text data as characters (for example, single-byte as
124 opposed to multi-byte characters in arguments).
125 LC_MESSAGES
127 Determine the locale that should be used to affect the format
128 and contents of diagnostic messages written to standard
129 error.
130 LOGNAME Determine the login name of the user.
132
134 Default.
135
137 None.
138
140 The standard error shall be used only for diagnostic messages.
141
143 None.
144
146 None.
147
149 The following exit values shall be returned:
150 0 Successful completion.
152 >0 An error occurred.
154
156 In addition to the default behavior, the qrls utility shall not be
157 required to write a diagnostic message to standard error when the error
158 reply received from a batch server indicates that the batch job_identi‐
159 fier does not exist on the server. Whether or not the qrls utility
160 waits to output the diagnostic message while attempting to locate the
161 job on other servers is implementation-defined.
162 The following sections are informative.
164
166 None.
167
169 None.
170
172 The qrls utility allows users, operators, and administrators to remove
173 holds from jobs.
174 The qrls utility does not support any job selection options or wildcard
176 arguments. Users may acquire a list of jobs selected by attributes
177 using the qselect utility. For example, a user could select all of
178 their held jobs.
179 The −h option allows the user to specify the type of hold that is to be
181 removed. This option allows for USER, SYSTEM, OPERATOR, and implementa‐
182 tion-defined hold types. The batch server that manages the batch job
183 will verify whether the user is authorized to remove the specified hold
184 for the batch job. If more than one type of hold has been placed on the
185 batch job, a user may wish to remove only some of them.
186 Mail is not required on release because the administrator has the tools
188 and libraries to build this option if required.
189 The qrls utility is a new utility vis-a-vis existing practice; it has
191 been defined in this volume of POSIX.1‐2008 as the natural complement
192 to the qhold utility.
193
195 The qrls utility may be removed in a future version.
