Push down Optimization is the great option provided by
informatica powercenter. this senario is used in both source
and targets are databases

Answer / jaspreet banga

One can push transformation logic to the source or target
database using pushdown optimization. The Integration
Service translates the transformation logic into SQL
queries and sends the SQL queries to the source or the
target database which executes the SQL queries to process
the transformations. The amount of transformation logic one
can push to the database depends on the database,
transformation logic, and mapping and session
configuration. The Integration Service analyzes the
transformation logic it can push to the database and
executes the SQL statement generated against the source or
target tables, and it processes any transformation logic
that it cannot push to the database.

just consider the example:----

Suppose a mapping contains a Filter transformation that
filters out all employees except those with a DEPTNO
greater than 40. The Integration Service can push the
transformation logic to the database. It generates the
following SQL statement to process the transformation logic:

INSERT INTO EMP_TGT(EMPNO, ENAME, SAL, COMM, DEPTNO)
SELECT
EMP_SRC.EMPNO,
EMP_SRC.ENAME,
EMP_SRC.SAL,
EMP_SRC.COMM,
EMP_SRC.DEPTNO
FROM EMP_SRC
WHERE (EMP_SRC.DEPTNO >40)
The Integration Service generates an INSERT SELECT
statement and it filters the data using a WHERE clause. The
Integration Service does not extract data from the database
at this time

What is a configuration management?

CANNOT USE PARAMETER FILE! Hi all, I am trying to use parameter file for my workflow. This could help me to filter records where CITY = 'Portland' Following is what I have done: **in Designer - create new parameter : $$PARA_FIL, Parameter, String, IsExprVar=TRUE, Initial value = [empty] - Source Qualifier/ Properties/Source Filter: CUSTOMERS.CITY='$$PARA_FIL' **Create Parameter file: C:\Informatica\PowerCenter8.6.0 \server\infa_shared\BWParam\DynamicParamTest.txt $$PARA_FIL='Portland' **Configure workflow to use the parameter file: Edit Workflow/Properties/Parameter Filename: C:\Informatica\PowerCenter8.6.0 \server\infa_shared\BWParam\DynamicParamTest.txt I also configured directory of parameter file for session task. However, I just got this in the session log: [SQ_CUSTOMERS] SQL Query [SELECT CUSTOMERS.CUSTOMER_ID FROM CUSTOMERS WHERE CUSTOMERS.CITY='$$PARA_FIL'] No record has been loaded to target. It seems that the parameter file has not been read. I cannot understand the reason why. Could any of you kindly suggest me anything? Thanks
