RE: What do Database Buffers contain ?
|
| Buffer Cache Stores the most recently used blocks of data. It can also have modified data that has not permenently written to disk. When a row in a table is updated the foreground server processes reads the datafile information on the disk in to the buffer cache. Hence modifying the data block in server memory. Oracle writes the block from the buffer cache to the LRU(Least Recently Used) Mechanism. |
