How to use Jukeboxes as Storage Location?
Jukeboxes provide space for several optical storage media which are inserted into the read drives on demand. Jukeboxes provide space for 100 up to more than 5000 storage media. Depending on what storage media you are using, jukeboxes can offer capacities well into the terabytes. These systems are clearly useful for networks that handle huge amounts of data. Access speed is dependent on the number of inbuilt drives. When frequent disk changes occur, access time can be several seconds per document file. In order to reduce these access time, jukebox solutions usually provide fast intermediate storage on a hard disk (on the jukebox itself or on the computer to which it is connected).
Notes on using jukeboxes
- As of DocuWare 5.1 Fix 2: BDs (Blu Ray Disks) are supported for jukebox storageIf DocuWare disks are being created in a jukebox, the user logged into DocuWare Administration must have rights to the server on which Jukebox Manager is installed.
- If the PoINT Jukebox Manager is installed on your computer you can record CDs only using the PoINT Jukebox Manager but not directly out of DocuWare.
- If you are using a jukebox you will not be able to create new DocuWare disks automatically, because an automation mechanism would take too long. You should therefore always make sure that you create enough DocuWare disks manually before you start. You do this in DocuWare Administration, by going to <Organization x> - File Cabinets - <File Cabinet x> - Documents Create and choosing Logical Disk from the context menu.
- If you are unable to save a document on the current jukebox disk because there is not enough space left on the associated medium, the medium is automatically finalized. The medium can then no longer be written to. As a result it can happen that the storage space on the medium may not be used to the full. If for example there are 3 MB left on a medium and you try to save a document of 4 MB, the medium will be finalized with 3MB of free storage space. The document is stored on the next medium.
- If you selected a jukebox as the storage location for a file cabinet, you may assign only one (and not several) Content Servers to that file cabinet. Otherwise problems can occur when media are finalized.
- If you store documents in a file cabinet that has a jukebox as the storage location, the document files are not written to the medium immediately, but saved in an image first. This happens until the medium is finalized. Then the complete image is burned on the medium in a single operation. The image is stored on the hard disk of the computer on which Jukebox Manager is running. The image must not exceed 8.5 GB in size. Particularly if you are using Blu-Ray disks you should have plenty of storage space on this computer and can therefore make regular backups of the image if necessary.
- If an error occurs when burning the image to the medium in the jukebox, the burn process is repeated on a new medium. The new medium is given the same name and the same settings (in particular the volume label) as the original medium, ensuring it is located in the same place in the virtual file system. A maximum of three burn attempts can be made for each image. The replacement media must reside in the same magazine as the original medium. The image is only deleted from the hard disk once the medium has been recorded in full and free of any errors.
- From version 6.9 on, Jukeboxes are not supported as storage location anymore
