`OBJ_NAME`	`VARCHAR2(128)`		Name of the object affected by the action
`ACTION`	`NUMBER`	`NOT NULL`	Numeric action type code. The corresponding name of the action type is in the `ACTION_NAME` column.
`ACTION_NAME`	`VARCHAR2(28)`		Name of the action type corresponding to the numeric code in the `ACTION` column
`NEW_OWNER`	`VARCHAR2(30)`		Owner of the object named in the `NEW_NAME` column
`NEW_NAME`	`VARCHAR2(128)`		New name of the object after a `RENAME` or the name of the underlying object

`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 `S` - Success `F` - Failure `B` - Both
`LOGOFF_TIME`	`DATE`		Date and time of user log off
`LOGOFF_LREAD`	`NUMBER`		Logical reads for the session
`LOGOFF_PREAD`	`NUMBER`		Physical reads for the session
`LOGOFF_LWRITE`	`NUMBER`		Logical writes for the session
`LOGOFF_DLOCK`	`VARCHAR2(40)`		Deadlocks detected during the session
`COMMENT_TEXT`	`VARCHAR2(4000)`		Text comment on the audit trail entry, providing more information about the statement audited Also indicates how the user 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 the Advanced Security option `PROXY` - Client was authenticated by another user; the name of the proxy user follows the method type
`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.

`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
