Two repository in server?

[liso]

Is it possible to have two repository in one server?

Yes. I have four! 

You just need to make sure each instance has its own set of ports and database and runs on its own instance of tomcat.   
There's a discussion in these forums already about this.

I tried it but both tomcats they don't want to start.

Have you changed the server.xml to move the tcp ports of one of the servers?    From memory there's 4 to change.
