The redo list is an internal database list of transactions that is created by the redo log manager. It is located in the main memory.
The redo list supplements the transaction list. The redo list contains a list of those transactions that have been started since the last savepoint, together with the order in which they are executed. These transactions must be repeated when the database is restarted or recovered.
