qrls - release batch jobs
qrls [-h hold_list] job_identifier ...
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.
The qrls utility shall conform to the Base Definitions volume of IEEE Std 1003.1-2001, 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 char- acter set (see the Base Definitions volume of IEEE Std 1003.1-2001, 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.
Not used.
The standard error shall be used only for diagnostic messages.
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.
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 imple- mentation-defined hold types. The batch server that manages the batch job will verify whether the user is authorized to remove the speci- fied 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 IEEE Std 1003.1-2001 as the natural complement to the qhold utility.
