Audit Trail File
The audit trail file contains all the audit records that are written by the audit daemon. You can specify either a central audit trail file or a vocal audit trail file.
The central audit trail file is created by the audit daemon when it is started. By default, if the dce_aud_open( ) function does not specify a name for an audit trail file, all audit records are sent to the audit daemon, which stores them in the central audit trail file.
If the dce_aud_open( ) function is invoked with a name for the trail file, this name becomes the pathname to the local audit trail file and all audit records are sent to that file.
