Connection lifetime (sec) . How long a connection made between the database
link and remote server remains open. You can keep connections between the
database link and the remote server open for an unspecified time, or you can
close them after a specific period of time.

example, if you are using a dial-up connection you may want to limit the
connection time.
A value of 0 indicates there is no limit. By default, the value is set to
0

database_link_name,

database,cn=plugins,cn=config
, where database_link_name is the name of the
database link. The connection management attributes specified in this entry take
