The parameters you set will depend on the configuration
you choose.
If the primary and standby databases are on the same server, you will need to set a value for
the DB_UNIQUE_NAME parameter. Because the directory structures for the two databases will
be different, you must either manually rename files or define values for the DB_FILE_NAME_
CONVERT and LOG_FILE_NAME_CONVERT parameters in the standby database. You must
set up unique service names for the primary and standby databases via the SERVICE_NAMES
initialization parameter.
