Well what I try to accomplish is that every location has access to the same datasource to share information about the solutions. The main problem is that not all of our location are on the same network. And I really don't want to place the OTRS-System in the DMZ because we want to use it as an internal helpdesk tool. So yes we want to have an installation on every site but with the same (replicated) Database. We need to have the database on every location as some of them have a real slow connection to our headquarter. And my colleagues around the world should still be able to work with the system if there internet connection is down. But I will try it with the master-master replication and see if this will do for us.

But I use the slave as a backup server. MySQL 5.1 even promises better replication. check: http://dev.mysql.com/doc/refman/5.1/en/mysql-nutshell.html But I do not understand what you want to accomplish with replicated databases as OTRS is pure browser based. IMHO: put the webserver very close to the database server and you will have the best performance. Or are you going tu use multiple distributed webservers? regards, Peter van Beugen -----Oorspronkelijk bericht----- Van: otrs-bounces@otrs.org namens Thorsten.Dannhausen@Bertelsmann.de Verzonden: wo 22-8-2007 19:06 Aan: otrs@otrs.org Onderwerp: [otrs] Database replication Hi, i'm working for an international operating company and we want to use otrs as our global helpdesk-system. So I need a way to replicate the databases to different location so that every location has the same view, or at least almost. Has anybody done this before and give me a little hint how to accomplish this. Many thanks in Advance Thorsten
