That getenrated redo size for this statement was 828 bytes. If an instance ecovery is needed, redo log files will be read and your transaction will be applied. If your transaction was committed, it will not be rolled back. Redo log files are only read during recovery. There are some ramifications about that and I believe that Mr. Rama Velpuri has written a few lines about those.
