This file contains the pointers for the Imaging Background Queue file. 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
| Property of the US Government. |
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
| No permission to copy or redistribute this software is given. |
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.
| Use of unreleased versions of this software requires the user |
| to execute a written test agreement with the VistA Imaging |
| Development Office of the Department of Veterans Affairs, |
| telephone (301) 734-0100. |
