## Redo List

The redo list is an internal database list of transactions that is created by the redo log manager. It is stored in the working memory.

The redo list supplements the transaction list. The redo list contains information on the transactions that the database system started after the most recent savepoint took place. The list also contains details of the sequence in which the transactions were carried out. These transactions will need to be repeated if a restart or restoring of the database instance is required.
