NORMAL LOAD : IT LOADS THE RECORD ONE BY ONE AND WRITES LOG
FOR EACH FILE . IT TAKES MORE TIME TO COMPLETE
BULK LOAD : I LOAD THE NUMBER OF RECORDS AT A TIME ,IT WONT
FALLOW ANT LOG FILES OR TRACE LEVELS . IT TAKES LESS TIME
USE THE BULK MODE FOR IMPROVING THE SESSION PERFORMANCE

Answer / addy

Hi

I would like to mention- apart from logging differences
there is a crucial diffrence - if we are running the session
in bulk target load mode we cant recover a session from the
same point when we run it for the next time.

whereas if we are running the session in normal target load
mode we can recover the session if the output being loaded
to the target is deterministic in nature - this is relay a
helpful feature with the applications handling RealTime data.

Answer / shashank

in the normal loading the taget write all the row on the
database log , while laoading the bulk loading the database
log is not come in the picture (that mean its skip the
property )so when the session got failed we can easily find
recover the seesion by the help of data base log.but in
case of bulk loading we can do .

but normaol loading is very slow as compare to bulk laoding.

Above 5,6&7 are the correct for this questions....

Answer / thiru

In normal loading it will creates the log file before
loading target.it will takes the time but in this sessiom
recovery is available.

In bulk loading the integration service bypasses the log
file,direct load into the target.inthis there is no session
recovery available but performance increase.

Answer / sankar

NORMAL LOADING:THE INTEGRATION SERVUCE CREATE THE DATA BASE
LOG BEFORE LOADING DATA INTO THE THE TARGET DATA BASE.SO
--THE INTEGRATION SERVICE PERFORM ROLL BACK AND SESSION
RECOVERY.
BULK LOADING:THE INTEGRATION SERVICE IN WORK THE BULK
UTILITY WHEN BYPASS THE DATA BASE LOG
--THIS IS IMPROVES THE PERFORMANCE DATA LOADING
--THIS IS NOT PERFORM ROLLBACK

1)Bulkload & Narmal load

Normal: In this case server manager allocates the
resources(Buffers) as per the parameter settings. It creates
the log files in database.

Bulk: In this case server manager allocates maximum
resources(Buffers) available irrespective of the parameter
settings. It will not create any log files in database.

In first case data loading process will be time taking
process but other applications are not affected. While in
bulk data loading will be much faster but other application
are affected.

Answer / jyothsna katakam

when you select the normal, it will check the p.k and f.k
relation ship while running the mapping but when you select
the bulk it wont check any p.k and f.k relation ship
