Attribute

Return Value

ACTION
Identifies the position in the module (application name) and is set through the DBMS_APPLICATION_INFO package or OCI.
SELECTsys_context('USERENV', 'ACTION') FROM dual;

exec dbms_application_info.set_action('INSERTING');

SELECTsys_context('USERENV', 'ACTION') FROM dual;
AUDITED_CURSORID
Returns the cursor ID of the SQL that triggered the audit. This parameter is not valid in a fine-grained auditing environment. If you specify it in such an environment, Oracle Database always returns
NULL.
AUTHENTICATED_IDENTITY
Returns the identity used in authentication. In the list that follows, the type of user is followed by the value returned:
Kerberos-authenticated enterprise user: kerberos principal name
Kerberos-authenticated external user : kerberos principal name; same as the schema name
SSL-authenticated enterprise user: the DN in the user's PKI certificate
SSL-authenticated external user: the DN in the user's PKI certificate
Password-authenticated enterprise user: nickname; same as the login name
Password-authenticated database user: the database username; same as the schema name
OS-authenticated external user: the external operating system user name
Radius/DCE-authenticated external user: the schema name
Proxy with DN : Oracle Internet Directory DN of the client
Proxy with certificate: certificate DN of the client

AUTHENTICATION_DATA
Data being used to
authenticate the login user. For X.503 certificate authenticated sessions, this field returns the context of the certificate in HEX2 format.

Note:You can change the return value of the AUTHENTICATION_DATA attribute using the length parameter of the syntax. Values of up to 4000 are accepted. This is the only attribute of USERENV for which Oracle implements such a change.
AUTHENTICATION_METHOD
Returns the method of authentication. In the list that follows, the type of user is followed by the method returned.
Password-authenticated enterprise user, local database user, or SYSDBA/SYSOPER using Password File; proxy with username using password: PASSWORD

For external users: the external identity (Kerberos principal name, Radius and DCE schema names, OS user name, Certificate DN).
For local users and SYSDBA/SYSOPER logins: NULL.

The value of the attribute differs by proxy method:
For a proxy with DN: the Oracle Internet Directory DN of the client
For a proxy with certificate: the certificate DN of the client for external users; the Oracle Internet Directory DN for global users
For a proxy with username: the Oracle Internet Directory DN if the client is an enterprise users; NULL if the client is a local database user.
