4.122 DBA_AUDIT_TRAIL

DBA_AUDIT_TRAIL displays all standard audit trail entries.

Note:

This view is populated only in an Oracle Database where unified auditing is not enabled. When unified auditing is enabled in Oracle Database, the audit records are populated in the new audit trail and can be viewed from UNIFIED_AUDIT_TRAIL.

USER_AUDIT_TRAIL displays the standard audit trail entries related to the current user.

  • 6 - INSERT
  • 7 - LOCK
  • 8 - CREATE
  • 9 - SELECT
  • 10 - UPDATE
  • 11 - REFERENCES
  • 12 - EXECUTE
  • 13 - VIEW
  • 14 - DROP
  • 15 - ANALYZE
  • 16 - CREATE

----------------------------Y---

SYS_PRIVILEGE

SES_ACTIONS

VARCHAR2(19)

Session summary (a string of 16 characters, one for each action type in the order ALTER, AUDIT, COMMENT, DELETE, GRANT, INDEX, INSERT, LOCK, RENAME, SELECT, UPDATE, REFERENCES, and EXECUTE). Positions 14, 15, and 16 are reserved for future use. The characters are:

  • - - None

COMMENT_TEXT

VARCHAR2(4000)

Text comment on the audit trail entry, providing more information about the statement audited

Also indicates how the user or remote call was authenticated. The method can be one of the following:

  • DATABASE - Authentication was done by password

  • NETWORK - Authentication was done by Oracle Net Services or strong authentication

  • PROXY - Client was authenticated by another user; the name of the proxy user follows the method type

When an object is accessed remotely over a database link, the COMMENT_TEXT column also captures the information about the database link. For example: 

DBLINK_INFO: (SOURCE_GLOBAL_NAME=view02.regress.rdbms.dev.us.example.com, 
DBLINK_NAME=VIEW05_LINK.REGRESS.RDBMS.DEV.US.EXAMPLE.COM, 
SOURCE_AUDIT_SESSIONID=250805)

SESSIONID

NUMBER

NOT NULL

Numeric ID for each Oracle session. Each user session gets a unique session ID.

ENTRYID

NUMBER

NOT NULL

Numeric ID for each audit trail entry in the session. The entry ID is an index of a session's audit entries that starts at 1 and increases to the number of entries that are written.

STATEMENTID

NUMBER

NOT NULL

nth statement in the user session. The first SQL statement gets a value of 1 and the value is incremented for each subsequent SQL statement. Note that one SQL statement can create more than one audit trail entry (for example, when more than one object is audited from the same SQL statement), and in this case the statement ID remains the same for that statement and the entry ID increases for each audit trail entry created by the statement.

RETURNCODE

NUMBER

NOT NULL

Oracle error code generated by the action. Some useful values:

  • 0 - Action succeeded

  • 2004 - Security violation

PRIV_USED

Timestamp of the creation of the audit trail entry (timestamp of user login for entries created by AUDIT SESSION) in UTC (Coordinated Universal Time) time zone

PROXY_SESSIONID

NUMBER

Proxy session serial number, if an enterprise user has logged in through the proxy mechanism

GLOBAL_UID

VARCHAR2(32)

Global user identifier for the user, if the user has logged in as an enterprise user

INSTANCE_NUMBER

NUMBER

Instance number as specified by the INSTANCE_NUMBER initialization parameter

OS_PROCESS

VARCHAR2(16)

Operating System process identifier of the Oracle process

TRANSACTIONID

RAW(8)

Transaction identifier of the transaction in which the object is accessed or modified

SCN

NUMBER

System change number (SCN) of the creation of the audit trail entry

SQL_BIND

NVARCHAR2(2000)

Bind variable data of the query

SQL_TEXT

NVARCHAR2(2000)

SQL text of the query

OBJ_EDITION_NAME

VARCHAR2(128)

Name of the edition containing the audited object

DBID

NUMBER

Database identifier of the audited database

RLS_INFO

CLOB

Stores virtual private database (VPD) policy names and predicates separated by delimiter.

To format the output into individual rows, use the DBMS_AUDIT_UTIL.DECODE_RLS_INFO_ATRAIL_STD function.

CURRENT_USER

VARCHAR2(128)

Effective user for the statement execution

Note:

The SQL_BIND and SQL_TEXT columns are only populated if the AUDIT_TRAIL initialization parameter is set to db, extended.
