The PAF requires a SQL repository to store the various components and gears that make up the PAF itself. The PAF automatically creates this repository during installation. The Nucleus address of the repository component is /atg/portal/framework/PortalRepository. For most portal applications, the default repository component and database script is sufficient. For custom implementations of the PAF, you can modify the PortalRepository definition file and database schema to create and extend repositories that suit your specific needs. However, Oracle technical support cannot support any changes you make to the default PortalRepository definition file and database schema.
