(1) Global database name : to differentiate from the following SID, is the real unique identity of the database, as everyone has their own identity card, a room can have a lot of people, but everyone has their own identity card, identity card is unique, can distinguish everyone. A network domain has multiple databases, but each database should have an identity that distinguishes it from other databases-the global database name. At the same time, the global database name is required to install the database, create a new database, create a database control file, modify the data structure, and back up and restore the database.

(We can pass: select name from V$database; command to view the current global database name. ）

(2) Manage Password: the password of the database.
