The sqlnet.ora file is very important file for database server and client machines, because it includes the profile configuration file ( tracing options, encryption, route of connections, external naming parameters etc).

Database server can be configured with access control parameters using the sqlnet.ora file.

[[email protected] admin]$


[[email protected] admin]$ cat sqlnet.ora
