During online logging, the undo log entries are managed. The modifying Structure linktransactions store the undo log entries in undo log files.

Undo log management plays a part in the following actions:

·        The database can create a transaction-consistent database state that reflects the state of the database system at the time of the last Structure linksavepoint. The information in the undo log files is sufficient for this.

·        In a restart or recovery, the required undo log entries are determined.

·        For the Structure linkdatabase instance type liveCache, History Management is carried out for the undo log entries.
