Answer Posted / pardhu
when u configure the session with the type normal the I.S
writes the data records to database log before inserting the
rows into target. when u configure the session with the type
bulk the I.S bypasses the database log it inserts the
records directly into target. In normal mode session
recovery is possible but in bulk mode session recovery is
not possible. bulk mode improves the performance.
