For WebCenter Framework Application should be deployed on WC_CustomPortal.
When installing WebCenter Portal you'll have:
WC_Spaces | For Portal (formerly Spaces)
WC_Utilities | For Analytics
WC_Portlet | For WRSP Portlets
WC_Collaboration | Forums
If you're planning to deploy Framework Portal you have to extend the domain:
- Creating new WebCenter Schemas for WC_CustomPortal using RCU.
- Extend the domain for having WC_CustomPortal server.
Remember that WC_Spaces and WC_CustomPortal should be using their own DB schemas (don't mix them).
I hope this information helps.
