Abstract
Log file amnesia detection is accomplished by associating a unique identifier with each record in a log file, where each record receives a unique log sequence number. Multiple time intervals are associated with the log file with different events triggering the beginning of a new time interval. The log file implementation marks the beginnings of these multiple time intervals with a unique identifier. Every time an event occurs that triggers a new time interval a new unique identifier is generated. This unique identifier will be associated with the records in the log file that are created thereafter until the next unique identifier gets generated, marking the beginning of a next time interval. Log file amnesia can be identified when a log client requests information about a record and then comparing the unique identifier and log sequence number of the record with all records in the log file.
