TRANSACTION_AUDITING

Parameter type	Boolean
Default value	true
Parameter class	Dynamic: ALTER SYSTEM ... DEFERRED
Range of values	true | false

If TRANSACTION_AUDITING is true, Oracle generates a special redo record that contains the user logon name, username, the session ID, some operating system information, and client information. For each successive transaction, Oracle generates a record that contains only the session ID. These subsequent records link back to the first record, which also contains the session ID.

These records might be useful if you are using a redo log analysis tool. You can access the records by dumping the redo log.

If TRANSACTION_AUDITING is false, no redo record will be generated.
