Auditing "alter database create datafile"

Hi

Under 10g Standard license, would enabling any of the following:

SQL> show parameter audit

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
audit_file_dest                      string      /u01/app/oracle/admin/swmfol/adump
audit_sys_operations                 boolean     FALSE
audit_syslog_level                   string
audit_trail                          string      NONE

facilitate auditing

alter database create datafile ...

please ?

If it does, I take it that with the settings above there will be no trace ?

Regards

Martin
