Figure 2-4 shows the default OracleAS Certificate Authority installation configuration, consisting of an Oracle9i Single Sign-on (SSO) instance, an OracleAS Certificate Authority instance, and an Oracle9i database, which contains an instance of Oracle Internet Directory (OID). Double-headed arrows connect SSO with both OID and the database. Another arrow points from the OracleAS Certificate Authority instance to the database.

The diagram shows web clients connected by double-headed arrows to either the SSO instance or to OracleAS Certificate Authority.
