DBWR (DataBase WRiter) is an Oracle background process created when you start a database instance. The DBWR writes modified data (dirty buffers) from the SGA into the Oracle database files. When the SGA data buffer cache fills the DBWR process selects buffers using an LRU algorithm and writes them to disk.
