1. What is IMU? What is the main role of IMU, that is, to solve the problem? IMU--->in Memory undo,10g new features, the database will open up separate memory areas in shared pool to store the Undo information. Each new transaction is assigned a IMU buffer (private), a buffer with many node, one node equivalent to a

possibly generate a large number of read I/O operations, which are resource-intensive operations. 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

Experiment content: The Redo Log Content format of the DML statement produced in the non-IMU mode is interpreted, the database version: 11.2.0.4 The most detailed explanation is update. Experimental environment Preparation The IMU feature is turned on by default in 11G, and this feature needs to be turned off for this experiment.

In the work contact with the gyroscope, and this Chinese expression in English there are many distinctions, such as MEMS, Gyro, IMU and so on.
