Oracle System Architecture Interview Question:

Explain what do Redo Log Buffers contain?

Submitted by: Administrator

Redo log buffers consists of change vectors where each vector contains information about which block is changed and where is the change done in the memory. This information will be useful when you are performing recovery and while writing to disk while checkpointing. There is a 1-to-1 correspondence with redo log buffers and data buffer cache buffers.
