[Koha] How to Host Multiple Database in KOHA 3.0.3

Greetings. I am using Debian Lenny Stable version and KOHA 3.0.3. I need to add multiple databases in my KOHA installation for hosting databases from various libraries. I have a manual explaining the process in KOHA 2.2.9 but I need it for KOHA 3.0.3. There is an issue with Zebra Server in KOHA 3.0.3, I guess. Please refer me to any links or resources that are available for this issue. Also, I've tried to configure the Offline Circulation Client but it shows an error of PHP-GTK2. I have listed the detail in a previous mail but I didn't get any response at all. Please Help. Regards. -- Nitesh Rijal BE IT http://niteshrijal.com.np +9779841458173
