Following excerpt from a PDF document "Database Licensing" downloaded from www.oracle.com which "provides guidelines regarding Oracle's policies in effect as of January 23, 2004". Of course any individual customer may negotiate their own terms, but clearly the intention is that standby databases are fully licensed. By contrast, in an HA cluster (such as Veritas VCS or HP Service Guard), where failover of the primary database to another node (still functioning as a primary) occurs "up to a total of ten separate days in any given calendar year", a separate license is not required.

Quote:
"Standby: One or many copies of the primary database are maintained on separate server(s) at all times. These systems are configured for disaster recovery purposes. If the primary database fails, the standby database is activated to act as the new primary database. In this environment, the primary and the standby databases must be fully licensed. Additionally, the same metric must be used when licensing the databases in a standby environment."
