Read moreLGWR or Redo Log writer or Log writer processback,”The log writer process (LGWR) is responsible for redo log buffer management–writing the redo log buffer to a redo log file on disk. LGWR writes all redo entries that have been copied into the buffer since the last time it wrote.The redo log buffer is a circular buffer.
