color:#1F497D'>If the one on the mainland is intended to be read-only—just
the OPAC, with no one placing reserves or anything—then you could do this
pretty easily with a MySQL replication slave on the mainland server. Tell the
mainland OPAC to look to that slave server, and the one on the islands to look
to the master. Only the MySQL replication traffic would have to go back and
forth. When the net link is up and moving pretty well, the replication would
be almost instant; MySQL can be taught to be tolerant of dodgy links, particularly
on one-way replication like this. The basic premise here is to let MySQL do
the work of hauling the data across the water for you; neither Koha instance
has to worry about it, and once it’s set up and happy, neither do you.<o:p></o:p></span></p>

color:#1F497D'>Installing the whole Koha is easy, and separating out the OPAC
would be a bit harder, so I’d just do that, and not define a web virtual
host to point to the staff client pages.<o:p></o:p></span></p>

<span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>Goal: To allow
Internet access to the library's OPAC.</span> <br>
<br>
<span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>Challenge: We
are a small research library located in the Galapagos Islands. Internet
connectivity is both intermittent and slow out here in the South Pacific, so
opening our webserver to the world is not a viable option. We are in the
process of installing Koha on our Intra-net webserver. We have contracted for
webhosting on a faster connection/server on the mainland of Ecuador and can
install Koha there. </span><br>
<span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>What is the
best configuration for running two Koha OPAC's at different locations? </span><br>
<span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>What is the
best way to exchange the data between the two locations?</span> <br>
<span style='font-size:10.0pt;font-family:"Arial","sans-serif"'> Do we
need to do a complete installation of Koha on the mainland server, or is there
an easy way just to install the webserver/OPAC module?</span> <br>
<br>
<span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>I look forward
to hearing for anyone who has attempted a similar project.</span> <br>
