DB Parameters - Global Database Name (GLOBAL_DB_NAME) (Doc ID 2643771.1)

Last updated on JULY 20, 2024

Applies to:

Oracle Database - Enterprise Edition - Version 10.2.0.1 and later
Information in this document applies to any platform.

Purpose

The global database name is the unique name of the database. In a distributed database system (a set of databases stored on multiple computers that typically appears to applications as a single database) the global database name ensures that each database is distinct from all other databases in the system. Oracle forms a database's global database name by prefixing the database's network domain with the individual database's name.

For example: sales.xx.oracle.com

The global database name defaults to DB_NAME.DB_DOMAIN and this value is marked at database creation time. If you change the DB_NAME or DB_DOMAIN after the database has been created, the value for the global database name (GLOBAL_NAME) will not change
