GLOBAL_NAMES parameter
is a combination of the database name and the domain name like “rose.corp.com”,
in which “rose” is the database name and “corp.com” is the domain name.
When you set the initialization parameter GLOBAL_NAMES to TRUE, the database ensures that the name of the database link is the same as the global database name of the remote database.
When you set the initialization parameter GLOBAL_NAMES to TRUE, the database ensures that the name of the database link is the same as the global database name of the remote database.
For example, if the global database name
for rose is rose.corp.com, and GLOBAL_NAMES is TRUE,
then the link name must be called rose.corp.com.
If you set the
initialization parameter GLOBAL_NAMES to FALSE,
then you are not required to use global naming. You can name the database link
whatever you want. For example, you can name a database link to rose.corp.com as flower.
