It tracks the status of queue processing. The Background Processor uses three files: 1. Queue (2006.03) 2. Queue Pointer (2006.031) 3. Jukebox (2006.032) There are five different tasks that can be performed by the background processor: 1. ABSTRACT -- create a small version of an image 2. EXPORT ---- copy an image to an export directory so that it can be used outside the imaging system 3. IMPORT ----copy an image from an import directory into the imaging system 4. JUKEBOX ---copy an image from hard disk to the jukebox 5. JBTOHD ----copy an image from the jukebox to the hard disk There is a single Input Queue file for all the requests, with a cross-reference to request type. The background processor processes the entries in a prioritized first-in first-out fashion, and uses the Queue Pointer file to record its progress. The background processor uses the Jukebox file for device-specific information. The jukebox platters are logically placed into the Network Location file, and are pointed to by the Jukebox file and the Image file. Jukeboxes, which can be configured as a single volume, only have a single entry in the network location file.
.01queue name(+)0;1FREE TEXTName of the queue holding the entry. The entry is controlled by the Imaging interfaces and should not be entered directly by any user.
.04place(+)0;4POINTER2006.1This field references the site parameter file. The Site parameter entry defines all of the attributes of Vista Imaging local area network. This includes facility user preferences, network write locations, etc.
1queue pointer0;2POINTER2006.03Pointer to the entry in the queue.
2queue count0;3NUMERICThis field provides a count of the queue entries that have yet to be processed in the Queue file (#2006.03) for each queue type.
3queue type total0;5NUMERICThis value is the total number of queues in the queue partition of this type for this local area Vista Imaging network. This value can be used in conjunction with the Queue Count field (#2) to determine the number of queues in the failed queue partition. i.e. Queue Type Total - Queue Count = failed queues (for this "PLACE" and this queue type)..
4last queue processed date time0;6DATE-TIMEThis is the latest date and time that this queue was processed. It is updated at the completion of the BP Queue process.
