    Unanswered: Redo Log

    Hi,

    What information redo exactly contain. Some blogs say it have only change vectors and some say it have both the change vectors as well data.

    How exactly instance recovery happens using redo logs and how the data is back using log miner?

    Purpose of standby redo logs both on the Primary and Standby? when we are using the LGWR process for the data apply on the standby

    Thanks

    90% of users' problems can be resolved by punching them - the other 10% by switching off their PCs.
