Parameter type



DB_NAME = database_name

Default value

There is no default value.

Parameter class


Real Application Clusters

You must set this parameter for every instance. Multiple instances must have the same value, or the same value must be specified in the STARTUP OPEN SQL*Plus statement or the ALTER DATABASE MOUNT SQL statement.

DB_NAME specifies a database identifier of up to 8 characters. If specified, it must correspond to the name specified in the CREATE DATABASE statement. Although the use of DB_NAME is optional, you should generally set it before issuing the CREATE DATABASE statement, and then reference it in that statement.

If you have multiple databases, the value of this parameter should match the Oracle instance identifier of each one to avoid confusion with other databases running on the system. The value of DB_NAME should be the same in both the standby and production initialization parameter files.

If you do not specify this parameter, you must specify a database name in either the STARTUP command or the ALTER DATABASE ... MOUNT statement for each instance of the cluster database.

The following characters are valid in a database name: alphanumeric characters, underscore (_), number sign (#), and dollar sign ($). No other characters are valid. Oracle removes double quotation marks before processing the database name. Therefore you cannot use double quotation marks to embed other characters in the name. The database name is case insensitive.
