Answer / nivas
Target Loading types are mainly catagorized into 2 types
1.Normal Loading
2.Bulk Loading
In the permoance Point of view Bulk Loading is better than
Normal Loading but session recovery is not possible because
of it's Byparses the session log.
Normal loading create the session log for session recovery.
Using Normal Loading only we will get session recovery.

Answer / 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.

When u chose target load type Normal mode the integration service creates database log and is used in session
recovery.
Where as in bulk mode the integration service by pass load the data into target, but its not
possible to create a session recover.
But in Bulk mode its faster in peformance.

Hi Friends,
Normally we have two types of loading. 1, Normal and 2. Bulk.
1 Normal: in this, data will load record by record and the integration service creates database log and is used in session because IS maintain the session log.
2 Bulk: In this, Data will insert Group of records, obviously bulk load will give better performance.
thanks,
kumar

Answer / sri
Bulk mode always create a session log and is used in
session recovery for eg . if we opt for bulk mode, if the
session fails after inserting 9000 rows on total of 10,000
rows (commit interval is after 10,000 rows) then we can
recover 9000 rows and can satrt the session for the rest of
row
In normal mode session log is not created and hence it is
faster than bulk mode .. Session recovery is not possible
in normal mode ..
