The following methods are available for authenticating database administrators:
■ Operating system (OS) authentication
■ A password file
Notes:
■ These methods replace the CONNECT INTERNAL syntax
provided with earlier versions of Oracle Database. CONNECT
INTERNAL is no longer supported.
■ Operating system authentication takes precedence over
password file authentication. If you meet the requirements for
operating system authentication, then even if you use a
password file, you will be authenticated by operating system
authentication.
Your choice will be influenced by whether you intend to administer your database
locally on the same machine where the database resides, or whether you intend to
administer many different databases from a single remote client.
If you are performing remote database administration, consult your Oracle Net
documentation to determine whether you are using a secure connection. Most popular
connection protocols, such as TCP/IP and DECnet, are not secure.
