SERVICE_NAMES

Parameter type	String
Syntax	SERVICE_NAMES = db_service_name [, db_service_name [,...] ]
Default value	DB_NAME.DB_DOMAIN if defined
Parameter class	Dynamic: ALTER SYSTEM
Range of values	Any ASCII string or comma-separated list of string names

SERVICE_NAMES specifies one or more names for the database service to which this instance connects. You can specify multiple service names in order to distinguish among different uses of the same database.

For example:

SERVICE_NAMES = sales.acme.com, widgetsales.acme.com

You can also use service names to identify a single service that is available from two different databases through the use of replication.

In an Oracle9i Real Application Clusters environment, you must set this parameter for every instance.

If you do not qualify the names in this parameter with a domain, Oracle qualifies them with the value of the DB_DOMAIN parameter. If DB_DOMAIN is not specified, Oracle uses the domain of your local database as it currently exists in the data dictionary.
