Writing audit records to the 'syslog' audit trail

Hi,

I would really appreciate the thoughts of anyone who is familiar with the option of writing audit details to the 'syslog' audit trail. At present, auditing is performed on my customer’s production databases, and audit records are held in the AUD$ table (i.e. parameter ‘audit_trail’ is set to ‘DB’). They also want to audit the activities of system/database administrators and other privileged users – this they propose to do by means of the ‘syslog’ audit trail. This is configured by, in their case, specifying parameter ‘audit_syslog_level=’local0.info’ ‘.

The following questions arise:

1.       Are audit details ever held in both locations – i.e. AUD$ and the syslog audit trail?
