normalloding:
this is the optin which we to set in the session under
mapping tab.this will represents the loading of data into
target.this is slower when compared to bulk load.this can
load the data even if u have constraints built on u r
target.this will create the session logs

Answer / prasanna

Session log is always created in any mode you load. The
loading method is no way realted to creation of a session
log.

Normal mode: Will check for constraints while loading. Its
a process which happens record by record.

Bulk mode: This will not check for any constraints on DB.
So, generally when you don;t have any indexes or
constraints defined on your target table, you can use Bulk
mode which is faster.
In Informatica 8.6.1 , if you define bulk mode also.. if
your task need to perform Normal mode operation,
informatica will chabge it to Normal mode automatically run
time.
