Answer / bharat kalra
In informatica ..bulk insert or bulk load does 2 things :-
1) Ignores the commit interval specified at the session
level.
2) Do not create a database session log file.
So, advantage is it's very fast as no entry goes into log.
Disadvantage is session cannot be rolled back as no entry
exists in the log file .

point only while loading to Sybase and DB2 whereas for
Oracle and SQL Server, it commits data at each commit
interval and start a new transacton after each commit.
