Database-Less Extraction of Event Logs from Redo Logs
2021
Business Information Systems
Preserved Fulltext
This paper proposes a semi-automatic approach to extract an event log from redo logs alone. It does not require access to the database or knowledge of the databaseschema. ...
These techniques are applied on event logs, which need to be extracted from the organization's databases beforehand. ...
Therefore, this paper proposes database-less extraction of event logs from redo logs. ...

In addition, an extracted event log provides only a single view on the database. ...
Process mining techniques require event logs which, in many cases, are obtained from databases. Obtaining these event logs is not a trivial task and requires substantial domain knowledge. ...
-Events: this sector collects a set of events, obtained from any available source (database tables, redo logs, change records, system logs, etc.). ...

For changes in slave table data, it effectively prevents the redo log from being written into the LOB database, while diminishing the amount of changes being recording within the undo journal. ...
It attempts to use LOB slave table methods to optimize and advance the storage structures of large objects as well as optimize the redo and undo log mechanisms to increase LOB access efficiency. ...
Using this method ensures that data can be restored through the redo log in the event of a crash, and also ensures the integrity and consistency of system data. ...
