Just a thought, running on three separate servers also spreads the work across three processors thus if one server goes down only one library goes down not all three. With the cheap prices of equipment especially if you get 3 used 1.2 gig processor boxes used and 15 inch monitors we give away just to rid our selves of them.... It almost makes sense ... of course there is always the space issue!<BR>
Three boxes takes up more room than three! <BR>

The good news is, not that hard at all :-)<BR>
<BR>
One of the katipo servers has 4 different koha's running on it.<BR>

Its not too bad, you need a different database, and a different<BR>
/etc/koha.conf file for each koha install.<BR>
And you need to edit the C4/Context.pm file to set the koha.conf for each<BR>
koha to use.<BR>
<BR>

><BR>
It depends entirely on how big the libraries are, and more importantly how<BR>
many transactions they each do a day.<BR>
The spec above sounds fine for 3 small libraries.<BR>
<BR>

You could do it with 3 databases, 3 config files, but they all share the<BR>
same perl and perl modules plus html::templates. <BR>
Its probably better to have separate installs though, which would allow you<BR>
to easily change the templates for each koha to make each library have its<BR>
own look.<BR>
<BR>
> Are there any "issues" about this type of hosting?<BR>
><BR>
<BR>
This is the solution Id go for if I wanted to run 3 separate catalogs.<BR>
However if I wanted to run a union catalog over the three libraries, id go<BR>
for a single Koha install, and use Koha's concept of branches to deal with<BR>
the separate libraries.<BR>
<BR>
I think it depends on the aim, do they want patrons to be able to search a<BR>
catalog and find books in all 3 libraries. Or would they rather have 3<BR>
separate catalogs.<BR>
