If you can reduce the Redo and Undo writes of Undo in these processes, it can obviously greatly improve database performance and reduce resource consumption and usage. Oracle introduced the In Memory Undo (IMU) technology In the database starting from Oracle10g. With this technology, the database will be In the Shared Memory (Shared Pool) the independen
