Cumulus and CD-ROM Jukeboxes
This infosheet should give you some more information about using CD jukeboxes
with the Cumulus image database.
One of the large number of possible configurations the Canto developers
tested with was the Kodak Professional PCD Jukebox 100. The software to
access the files on the CDs was the Kodak Professional PCD Jukebox Manager
1.2. As it was said above there are more jukeboxes from different vendors
on the market as well.
The jukebox needs to be connected to the server on which the Cumulus server
application is installed. Using a Macintosh server connected to the jukebox
is an affordable and powerful solution for handling a large number of images
on different CDs. You have the full access to all the files on the different
CDs without exchanging them manually. In case of the Kodak Professional
PCD Jukebox 100 Cumulus is the one and only application giving you the full
access to these files.
The Macintosh operating system is not able to handle all the different CDs
in the Jukebox as mountable volumes. This is an upper class feature offered
by connecting the jukebox to a Unix-Fileserver. In this case you have the
full access to all the different CDs in the Jukebox as shared volumes. This
solution offers a much easier handling of the volumes and its files but
of course this fact has its effect on the cost of the solution.
Extra benefit can be added by using an OPI system. It is recommended to
store the Sample Files on a hard-disk and the high resolution files on the
CDs in the Jukebox. This configuration minimizes the traffic in the Jukebox
while working on the layouts. There is only one access to the high resolution
file at the end of the workflow done by the printer spooler exchanging the
sample against the high resolution file.
When the user tries to access an image stored in the jukebox connected to
the server from the client the Cumulus resolver tries to access the image
on a local CD-ROM first and prompts the user to insert the CD-ROM into the
local drive. If the user cancels the procedure the client asks the server
if he is able to resolve the alias and the server offers a copy of the image
to the client if possible. In the case the user knows that all the images
are stored in the jukebox it is possible to install a resolver on the client
that always returns an error code telling the client not to try to access
the image on the local CD-ROM and not to display the insert-dialog but to
ask the server for a copy of the image. Canto Software offers a developers
toolkit to build your own resolver.
Remark: it is not possible to activate File Sharing on the server otherwise
the system would not be able to exchange the CDs in the Jukebox.
