[Koha] Running koha from removable media

Krishnan,
This is a great start. The intention for this concept is to provide
remote knowledge centre's with a simple way to use their computer to
monitor their books, CD's and DVD's , in places without tech support or
reliable computers.
These remote communities don't get support or funding to purchase a
library management system and so I am wondering if it would be very
difficult to make a USB stick library management system. A copy could
be made - one for the administrator as the master and one for the public
to use for browsing. Any changes can be made on the 'admin stick',
duplicating this at any time would update the public database.
It would be best if it could be run from within a Windows environment
without having to boot from the stick. This way, any computer that is
working (desktop PC or a laptop) could be used to host the USB stick and
software. Most of these remote libraries would have less than 1000 items
total. Some have Internet - some don't. I have started a blog with a map
showing where they all are : http://ikcnetwork.blogspot.com/
I might try and create mu own kitchen sink!
Cheerio,
James

While i haven't tried it yet, it should certainly be possible.
The Koha installer merely adds "web resources" (perl, javascript,
images, and such), and a couple of configuration files for itself and
Apache
Koha depends on Apache, MySQL, and Perl language facilities plus Perl
modules. The configuration file and the database contain everything
unique that Koha "knows" about a particular installation.
Indeed, very often i simply do a 'mysqldump' of Koha's database to my
own USB stick when i want to work on my library catalog on my laptop
elsewhere, instead of on the server itself.
Also, i have the same database user setup, so that config files match.
Also, a user called 'koha' on the operating system itself, that owns all
of Koha's files. Of course, there are security risks with just setting
up users on multiple machines this way.
i have no experience with zebra, and can't comment on its configuration.
A 'lite' version on a stick might assume that these are available on the
server you plug it into, BUT have the database (and config) files on the
stick itself so you can move between servers.
A 'full' version might bundle everything, but the OS. A 'kitchen-sink'
version is probably one that you can boot into with a full OS.
Now, for some data: A 'du -sh /usr/share/koha' yields 316Mbytes
Similar du -sh readings are as follows:
316M /usr/share/koha
1.4M /var/lib/mysql/koha3/
476M /usr/local/share/perl/
6.6M /usr/local/lib/perl/
The first is all the files for Koha's "pages". The second is a
relatively freshly-installed Koha database (not much data), and the last
two are the Perl modules Koha needs (and some more). This suggests a
size under 1 Gig for the whole gig (pun intended)
a USB stick throws up interesting possibilities for distribution, since
i have now been supplying DVDs for Koha installs in places where no
Internet is available. More about that in later mail.
regards,
krishnan

Hello
Has anyone ever heard of anyone attempting to run a simple library
management system off a USB Stick?
With USB sticks getting larger, and various solutions offering to boot
Linux from your portable USB stick, would it be possible to run a
version of koha that could manage a small library collection? I'm not
very cluey about client / database solutions, but I noticed one post
mentioning Koha running on a standalone PC with the client accessing the
localhost.
Also, how large would a koha installation be?
Cheerio,
James
