Audit files (i.e. those created by the AUDITFILE Emitter) cannot be reused until they have been dumped. Dumping involves the creation of backup files or reports using the audit file APIs (see the CBL_AUDIT_FILE_xxx in the Audit Facility APIs). Once an audit file has been successfully dumped it will be marked as being available for reuse.
An audit file cannot be dumped until it has been marked as being available for dumping. An audit file will be implicitly marked as being available for dumping once it has reached its maximum size. An administrator may explicitly mark the active file in a collection as available for dumping by using the Audit Facility Administration Utility, but doing this will cause the file to be immediately closed and the next file in the collection opened and made active.
