I don't think you can do what you want. The portal database is maintained for the jboss-portal.sar service that you deployed to the application server. All individual portals and portlets deployed to that application server are maintained by that same jboss-portal.sar service, and thus will be in the database used by that service. If you really want individual portals to be in separate databases, you will need two application servers running, each with jboss-portal.sar deployed to it. And each one configured to use a different database. However, portlet instances could be set up such that each uses a different database to access business data (not portal data). For example, give each portlet instance a different datasource preference and have the portlet use that preference to access the business data.
