(Valid for QUI$_DISPLAY_ENTRY, QUI$_DISPLAY_QUEUE function codes)

QUI$_QUEUE_NAME

Returns, as a character string, the name of the specified queue or the name of the queue that contains the specified job. Because a queue name can include up to 31 characters, the buffer length field of the item descriptor should specify 31 (bytes).

(Valid for QUI$_DISPLAY_ENTRY, QUI$_DISPLAY_JOB, QUI$_DISPLAY_QUEUE, QUI$_TRANSLATE_QUEUE function codes)

QUI$_QUEUE_STATUS

Returns the specified queue's status flags, which are contained in a longword bit vector. Some of these bits describe the queue's state, others provide additional status information.

The $QUIDEF macro defines the following symbolic names for these flags:
Symbolic Name Description
QUI$V_QUEUE_ALIGNING Queue is printing alignment pages.
QUI$V_QUEUE_AUTOSTART_INACTIVE Autostart queue is stopped due to failure or manual intervention and needs to be manually started.
QUI$V_QUEUE_AVAILABLE 1 Queue is processing work but is capable of processing additional work.
QUI$V_QUEUE_BUSY 1 Queue cannot process additional jobs because of work in progress.
QUI$V_QUEUE_CLOSED Queue is closed and will not accept new jobs until the queue is put in an open state.
QUI$V_QUEUE_DISABLED 1 Queue is not capable of being started or submitted to.
QUI$V_QUEUE_IDLE 1 Queue contains no job requests capable of being processed.
QUI$V_QUEUE_LOWERCASE Queue is associated with a printer that can print both uppercase and lowercase characters.
QUI$V_QUEUE_PAUSED 1 Execution of all current jobs in the queue is temporarily halted.
QUI$V_QUEUE_PAUSING 1 Queue is temporarily halting execution.
QUI$V_QUEUE_REMOTE Queue is assigned to a physical device that is not connected to the local node.
QUI$V_QUEUE_RESETTING Queue is resetting and stopping.
QUI$V_QUEUE_RESUMING 1 Queue is restarting after pausing.
QUI$V_QUEUE_SERVER Queue processing is directed to a server symbiont.
QUI$V_QUEUE_STALLED 1 Physical device to which queue is assigned is stalled; that is, the device has not completed the last I/O request submitted to it.
QUI$V_QUEUE_STARTING 1 Queue is starting.
QUI$V_QUEUE_STOP_PENDING Queue will be stopped when work currently in progress has completed.
QUI$V_QUEUE_STOPPED 1 Queue is stopped.
QUI$V_QUEUE_STOPPING 1 Queue is stopping.
QUI$V_QUEUE_UNAVAILABLE Physical device to which queue is assigned is not available.


1Bit describes the current state of the queue. Only one of these bits can be set at any time.

(Valid for QUI$_DISPLAY_ENTRY, QUI$_DISPLAY_QUEUE function codes)

QUI$_RAD (Alpha and I64)

Returns the value of the RAD attribute attached to a queue or a job. The item code expects a 32-bit buffer in which to write the value of the RAD. A value of -1 is returned to the buffer if no RAD is specified for the queue or the job.

Note: OpenVMS support for RADs is available only on the AlphaServer GS series systems. For more information about using RADs, see the HP OpenVMS Alpha Partitioning and Galaxy Guide.

(Valid for QUI$_DISPLAY_ENTRY, QUI$_DISPLAY_JOB, QUI$_DISPLAY_QUEUE function codes)

QUI$_REQUEUE_QUEUE_NAME

Returns, as a character string, the name of the queue to which the specified job is reassigned. This item code only has a value if the QUI$V_JOB_ABORTING bit is set in the QUI$_JOB_STATUS longword, and the job is going to be requeued to another queue.

Because a queue name can include up to 31 characters, the buffer length of the item descriptor should specify 31 (bytes).

(Valid for QUI$_DISPLAY_ENTRY, QUI$_DISPLAY_JOB function codes)

QUI$_RESTART_QUEUE_NAME

Returns, as a character string, the name of the queue in which the job will be placed if the job is restarted.

(Valid for QUI$_DISPLAY_ENTRY, QUI$_DISPLAY_JOB function codes)

QUI$_RETAINED_JOB_COUNT

Returns, as a longword integer value, the number of jobs in the queue retained after successful completion plus those retained on error.

(Valid for QUI$_DISPLAY_QUEUE function code)

QUI$_SCSNODE_NAME

Returns, as a character string, the name of the node on which the specified execution queue or queue manager is located. Because the node name can include up to 6 characters, the buffer length field of the item descriptor should specify 6 (bytes).

(Valid for QUI$_DISPLAY_QUEUE, QUI$_DISPLAY_MANAGER function codes)

QUI$_SEARCH_FLAGS

When you specify QUI$_SEARCH_FLAGS, an input value item code, it specifies a longword bit vector wherein each bit specifies the scope of $GETQUI's search for objects specified in the call to $GETQUI. The $QUIDEF macro defines symbols for each option (bit) in the bit vector.

The following table contains the symbolic names for each option and the function code for which each flag is meaningful:
Symbolic Name Function Code Description
QUI$V_SEARCH_ALL_JOBS QUI$_DISPLAY_JOB $GETQUI searches all jobs included in the established queue context. If you do not specify this flag, $GETQUI only returns information about jobs that have the same user name as the caller.

QUI$V_SEARCH_THIS_JOB QUI$_DISPLAY_FILE
QUI$_DISPLAY_JOB
QUI$_DISPLAY_QUEUE
$GETQUI returns information about the calling batch job, the command file being executed, or the queue associated with the calling batch job. $GETQUI establishes a new queue and job context based on the job entry of the caller; this queue and job context is dissolved when $GETQUI finishes executing. If you specify QUI$V_SEARCH_THIS_JOB, $GETQUI ignores all other QUI$_SEARCH_FLAGS options.
QUI$V_SEARCH_TIMED_RELEASE_JOBS QUI$_DISPLAY_ENTRY
QUI$_DISPLAY_JOB
QUI$_DISPLAY_QUEUE

$GETQUI performs a search in wildcard mode even if QUI$_SEARCH_NAME contains no wildcard characters.

QUI$_SEARCH_JOB_NAME

QUI$_SEARCH_JOB_NAME is an input value item code that specifies a 1- to 39-character string that $GETQUI uses to restrict its search for a job or jobs. $GETQUI searches for job names that match the job name input value for the given user name. Wildcard characters are acceptable.

(Valid for QUI$_DISPLAY_ENTRY function code)

QUI$_SEARCH_NAME

QUI$_SEARCH_NAME is an input value item code that specifies, as a 1- to 31-character string, the name of the object about which $GETQUI is to return information. The buffer must specify the name of a characteristic, form, or queue.

To direct $GETQUI to perform a wildcard search, you specify QUI$_SEARCH_NAME as a string containing one or more of the wildcard characters (% or *).

(Valid for QUI$_DISPLAY_CHARACTERISTIC, QUI$_DISPLAY_FORM, QUI$_DISPLAY_MANAGER, QUI$_DISPLAY_QUEUE, QUI$_TRANSLATE_QUEUE function codes)

QUI$_SEARCH_NUMBER

QUI$_SEARCH_NUMBER is an input value item code that specifies, as a longword integer value, the number of the characteristic, form, or job entry about which $GETQUI is to return information. The buffer must specify a longword integer value.

QUI$_SEARCH_USERNAME

QUI$_SEARCH_USERNAME is an input value item code that specifies, as a 1- to 12-character string, the user name for $GETQUI to use to restrict its search for jobs. By default, $GETQUI searches for jobs whose owner has the same user name as the calling process.

(Valid for QUI$_DISPLAY_ENTRY function code)

QUI$_SUBMISSION_TIME

Returns, as a quadword absolute time value, the time at which the specified job was submitted to the queue.

(Valid for QUI$_DISPLAY_ENTRY, QUI$_DISPLAY_JOB function codes)

Returns, in standard longword format, the UIC of the owner of the specified job.

(Valid for QUI$_DISPLAY_ENTRY, QUI$_DISPLAY_JOB function codes)

QUI$_USERNAME

Returns, as a character string, the user name of the owner of the specified job. Because the user name can include up to 12 characters, the buffer length field of the item descriptor should specify 12 (bytes).

(Valid for QUI$_DISPLAY_ENTRY, QUI$_DISPLAY_JOB function codes)

QUI$_WSDEFAULT

Returns, in pages (on VAX systems) or pagelets (on Alpha and I64 systems), the default working set size specified for the specified job or queue, which is a longword integer in the range 1 through 65,535. This value is meaningful only for batch jobs and execution queues.

(Valid for QUI$_DISPLAY_ENTRY, QUI$_DISPLAY_JOB, QUI$_DISPLAY_QUEUE function codes)

(Valid for QUI$_DISPLAY_ENTRY, QUI$_DISPLAY_JOB, QUI$_DISPLAY_QUEUE function codes)


Description

The Get Queue Information service returns information about queues and the jobs initiated from those queues. The $GETQUI and $SNDJBC services together provide the user interface to the queue manager and job controller processes. See the Description section of the $SNDJBC service for a discussion of the different types of jobs and queues.

The $GETQUI service completes asynchronously; that is, it returns to the caller after queuing the request, without waiting for the operation to complete. For synchronous completion, use the Get Queue Information and Wait ($GETQUIW) service. The $GETQUIW service is identical to $GETQUI in every way except that $GETQUIW returns to the caller after the operation has completed.

Classes and Types of Queues

The $GETQUI item codes and function codes can be specific to the type and class of the queue. For example, QUI$_LAST_PAGE applies only in the context of a printer or terminal execution queue, and QUI$_LOG_SPECIFICATION applies only to batch files.

The following information shows the two classes and the various types of queues, while the descriptions of the individual $GETQUI item codes and function codes indicate the associated queue class and queue type requirements:

The following table lists the Execution queue types:
Type Description
Batch execution queues Batch execution queues accept only batch jobs.
Output execution queues Output execution queues accept jobs that a symbiont processes, and include the following types:
  • Printer execution queue---Uses a symbiont to direct output to a printer.
  • Terminal execution queue---Uses a symbiont to direct output to a terminal printer.
  • Server execution queue---Uses a user-modified or user-written symbiont to process the files that belong to jobs in the queue.

The following table lists the Generic queue types:
Type Description
Generic batch queues Generic batch queues direct jobs only to batch execution queues.
Generic output queues Generic output queues direct jobs to any of the three types of output execution queues: print, terminal, or server.
Logical queues Logical queues are a special type of generic output queue that transfers jobs to another output execution queue.

For additional information, see the HP OpenVMS System Manager's Manual, Volume 1: Essentials.

You can specify the following function codes to return information for the object types listed:
Function Code Object Type
QUI$_DISPLAY_CHARACTERISTIC Characteristic
QUI$_DISPLAY_FORM Form
QUI$_DISPLAY_QUEUE Queue
QUI$_DISPLAY_MANAGER Queue manager
QUI$_DISPLAY_JOB Job within a queue context
QUI$_DISPLAY_FILE File within a job context
QUI$_DISPLAY_ENTRY Job independent of queue

Maintaining Context Across $GETQUI Calls

When you call the $GETQUI service, the queue manager establishes an internal GETQUI context block (GQC). The system uses the GQC to store information temporarily and to keep track of its place in a wildcard sequence of operations. The system provides any number of GQC blocks per process.

To allow you to obtain information either about a particular object in a single call or about several objects in a sequence of calls, $GETQUI supports three different search modes. The following search modes affect the disposition of the GQC in different ways:

The sections that follow describe how each of the three search methods affects $GETQUI's search for information; how you direct $GETQUI to undertake each method; and how each method affects the contents of the GQC.

Nonwildcard Mode

In nonwildcard mode, $GETQUI can return information about the following objects:

To obtain information about a specific characteristic or form definition, you call $GETQUI using the QUI$_DISPLAY_CHARACTERISTIC or QUI$_DISPLAY_FORM function code. You need to specify either the name of the characteristic or form in the QUI$_SEARCH_NAME item code or the number of the characteristic or form in the QUI$_SEARCH_NUMBER item code. The name string you specify cannot include either of the wildcard characters (* or %). You can specify both the QUI$_SEARCH_NAME and QUI$_SEARCH_NUMBER item codes, but the name and number you specify must be associated with the same characteristic or form definition.

To obtain information about a specific queue definition, you specify the QUI$_DISPLAY_QUEUE function code and provide the name of the queue in the QUI$_SEARCH_NAME item code. The name string you specify cannot include the wildcard characters (* or %).

To obtain information about a specific queue manager, specify the QUI$_DISPLAY_MANAGER function code and provide the name of the queue manager in the QUI$_SEARCH_NAME item code. The name string you specify cannot include the wildcard characters (* or %).

To obtain information about a specific batch or print job, specify the QUI$_DISPLAY_ENTRY function code and provide the entry number of the job in the QUI$_SEARCH_NUMBER item code.

Finally, the $GETQUI service provides an option that allows a batch job to obtain information about the queue, job, or command file that the associated batch job is executing without first entering wildcard mode to establish a queue or job context. You can make a call from the batch job that specifies the QUI$_DISPLAY_QUEUE function code to obtain information about the queue from which the batch job was initiated; the QUI$_DISPLAY_JOB function code to obtain information about the batch job itself; or the QUI$_DISPLAY_FILE function code to obtain information about the command file for the batch job. For each of these calls, you must select the QUI$V_SEARCH_THIS_JOB option of the QUI$_SEARCH_FLAGS item code. When you select this option, $GETQUI ignores all other options in the QUI$_SEARCH_FLAGS item code.

Wildcard Mode

In wildcard mode, the system saves the GQC between calls to $GETQUI so that you can make a sequence of calls to $GETQUI to get information about all characteristics, forms, queues, jobs, or queue managers contained in the queue database.

You can have several streams of operations open at one time. To use a stream, specify a unique longword value for the context argument for every call associated with that stream. If you do not specify the context argument, then context #0 will be used.

To set up a wildcard search for characteristic or form definitions, specify the QUI$_DISPLAY_CHARACTERISTIC or QUI$_DISPLAY_FORM function code and specify a name in the QUI$_SEARCH_NAME item code that includes one or more wildcard characters (* or %).

To set up a wildcard search for queues, use the QUI$_DISPLAY_QUEUE function code and specify a name in the QUI$_SEARCH_NAME item code that includes one or more wildcard characters (* or %). You can indicate the type of the queue you want to search for by specifying any combination of the following options for the QUI$_SEARCH_FLAGS item code:

QUI$V_SEARCH_BATCH
QUI$V_SEARCH_PRINTER
QUI$V_SEARCH_SERVER
QUI$V_SEARCH_TERMINAL
QUI$V_SEARCH_SYMBIONT
QUI$V_SEARCH_GENERIC

For example, if you select the QUI$V_SEARCH_BATCH option, $GETQUI returns information only about batch queues; if you select the QUI$V_SEARCH_SYMBIONT option, $GETQUI returns information only about output queues (printer, terminal, and server queues). If you specify none of the queue type options, $GETQUI searches all queues.

To set up a wildcard search for queue managers, specify the QUI$_DISPLAY_MANAGER function code and specify a name in the QUI$_SEARCH_NAME item code that includes one or more wildcard characters (* or %).

To set up a wildcard search for jobs, specify the QUI$_DISPLAY_ENTRY function code and the QUI$_SEARCH_WILDCARD option of the QUI$_SEARCH_FLAGS item code. When you specify this option, omit the QUI$_SEARCH_NUMBER item code. You can restrict the search to jobs having particular status or to jobs residing in specific types of queues, or both, by including any combination of the following options for the QUI$_SEARCH_FLAGS item code:

QUI$V_SEARCH_BATCH
QUI$V_SEARCH_EXECUTING_JOBS
QUI$V_SEARCH_HOLDING_JOBS
QUI$V_SEARCH_PENDING_JOBS
QUI$V_SEARCH_PRINTER
QUI$V_SEARCH_RETAINED_JOBS
QUI$V_SEARCH_SERVER
QUI$V_SEARCH_SYMBIONT
QUI$V_SEARCH_TERMINAL
QUI$V_SEARCH_TIMED_RELEASE_JOBS

You can also force wildcard mode for characteristic, form, or queue display operations by specifying the QUI$V_SEARCH_WILDCARD option of the QUI$_SEARCH_FLAGS item code. If you specify this option, the system saves the GQC between calls, even if you specify a nonwildcard name in the QUI$_SEARCH_NAME item code. Whether or not you specify a wildcard name in the QUI$_SEARCH_NAME item code, selecting the QUI$V_SEARCH_WILDCARD option ensures that wildcard mode is enabled.

Once established, wildcard mode remains in effect until one of the following actions causes the GQC to be released:

Note that wildcard mode is a prerequisite for entering nested wildcard mode.

Nested Wildcard Mode

In nested wildcard mode, the system saves the GQC between calls to $GETQUI so that you can make a sequence of calls to $GETQUI to get information about jobs that are contained in a selected queue or files of the selected job. Nested wildcard mode reflects the parent-child relationship between queues and jobs and between jobs and files. The $GETQUI service can locate and return information about only one object in a single call; however, queues are objects that contain jobs and jobs are objects that contain files. Therefore, to get information about an object contained within another object, you must first make a call to $GETQUI that specifies and locates the containing object and then make a call to request information about the contained object. The system saves the location of the containing object in the GQC along with the location of the contained object.

Note that the context number specified in the context argument must remain the same for each level of nesting.

Two of $GETQUI's operations, QUI$_DISPLAY_JOB and QUI$_DISPLAY_FILE, can be used only in a nested wildcard mode, with one exception. The exceptional use of these two operations involves calls made to $GETQUI from a batch job to find out more information about itself. This exceptional use is described at the end of the Nonwildcard Mode section.

You can enter nested wildcard mode from either wildcard display queue mode or from wildcard display entry mode. To obtain job and file information in nested wildcard mode, you can use a combination of QUI$_DISPLAY_QUEUE, QUI$_DISPLAY_JOB, and QUI$_DISPLAY_FILE operations. To obtain file information, you can use a combination of QUI$_DISPLAY_ENTRY and QUI$_DISPLAY_FILE operations as an alternative.

To set up a nested wildcard search for job and file information, you first perform one or more QUI$_DISPLAY_QUEUE operations in wildcard mode to establish the queue context necessary for the nested display job and file operations. Next you specify the QUI$_DISPLAY_JOB operation repetitively; these calls search the current queue until a call locates the job that contains the file or files you want. This call establishes the job context. Having located the queue and the job that contain the file or files, you can now use the QUI$_DISPLAY_FILE operation repetitively to request file information.
