Multiple customer Portals

Content

Hi All,

1.) Is it possible to have more than one customer portal i.e for the same site we have one portal as abc.custhelp.com and another PQR.custhelp.com?

2.) Is there any way we can separately create the DB is service cloud something same as a Schema that we do in our database.

3.)  Are there any articles/documentation around having multiple interface of OSvC.

Thanks
