Answer / jagadish
update strategy transformation is used to perform DML
operations for the already data populated targets.
by default informatica server will treat source row as
INSERT.if you use update strategy transformation in your
mapping the informatica server will treat source row as
DATA DRIVEN.so the datas transferd to a target that even
populated with some data can be inserted,updated,rejected
and deleted.based upon the functions like
dd_insert,dd_update,dd_reject,dd_delete you define in the
update strategy transformation.

Answer / obulreddy.b
IT IS A TRANSFORMATION WHICH IS USED TO PERFORM DML
OPERATIONS ON ALREADY DATA POPULATED TARGETS.
GENERALLY INFORMATICA SERVER WILL TREAT SOURCE ROWS AS
INSERT. IF WE USE UPDATE STRATOGY TRANSFORMATION WE HAVE TO
SELECT TREAT SOURCE ROWS AS DATADRIVEN IN SESSION
PROPERTIES, NOW INFORMATICA SERVER DRIVES THE DATA AS PER
UPDATE STRATOGY VALUE.
WE HAVE TO SELECT UPDATE STRATOGY VALUE BASED ON OUR
REQUIREMENT.

Differentiate between source qualifier and filter transformation?
we have a parameter file in Unix location where we have .txt files and those file will be used as source in informatica. I cannot use source file name directly as file name will keep on changing in unix location. I need to define $$InputFile as parameter. Can anybody send me the parameter file and the steps to handle this.
