Hi,

From the Oracle 10g Concept Guide (Chapter 9 - Process Architecture):

"When a user issues a COMMIT statement, LGWR puts a commit record in the redo log buffer and writes it to disk immediately, along with the transaction's redo entries. The corresponding changes to data blocks are deferred until it is more efficient to write them. This is called a fast commit mechanism."

Best regards.

Frank
