1.Every 3 secs
2.At commit(when a tx commits)
3.When one third of redo log buffer is filled.
4.When there is more than 1 Mb of redo entries(redo data or
changes) in the redo log buffer
5.Before DBWR background process writes dirty buffers from

At any of the above instances(cases) lgwr writes the redo
