Determining the Global Database Name (86)

The global database name consists of the user-specified local database name and the
location of the database within a network structure. The DB_NAME initialization
parameter determines the local name component of the database name, and the
DB_DOMAIN parameter indicates the domain (logical location) within a network
structure. The combination of the settings for these two parameters must form a
database name that is unique within a network.

For example, to create a database with a global database name of
test.us.acme.com, edit the parameters of the new parameter file as follows:

DB_NAME = test
DB_DOMAIN = us.acme.com

You can rename the GLOBAL_NAME of your database using the ALTER DATABASE
RENAME GLOBAL_NAME statement. However, you must also shut down and restart the
database after first changing the DB_NAME and DB_DOMAIN initialization parameters
and re-creating the control file.
