How is the union transformation active transformation? 364. On a day, I load 10 rows in my target and on next day if I get 10 more r ows to be added to my target out of which 5 are updated rows how can I send them to target? How can I insert and update the record? 365. Why sorter transformation is an active transformation? 366. How do we analyse the data at database level? 367. How u will create header and footer in target using informatica? 368. How to export mappings to the production environment? 369. Can any one tell me how to run scd1 bec it create two target tables in m apping window and there are only one table in warehouse designer(means target).. so if we create one new table in target it gives error.. 370. When do u we use dynamic cache and when do we use static cache in an con nected and unconnected lookup transformation 371. I have a situation here to load the Table into informatica. I have 5 tem porary tables as sources. They look like: Table1: (K - Key, N-Null, X,Y,Z - valu es) K1 X N N N N K2 X N N N N -------------------------- Table2: K1 N X N N N K2 N X N N N -------------------------- the other 3 tables are in the same way. Bu t there can be a situation like any of the table can contain duplicates like: K1 X N N N N K1 Y N N N N -------------------------- This kind of records should b e errored out. Because of this, we can't use aggregator/group by as we are not s ure which one should be removed. How can we obtain this functionality in Informa tica. 372. What are the different types of transformation available in informatica. and what are the mostly used ones among them 373. In certain mapping there are four targets tg1,tg2,tg3 and tg4. tg1 has a primary key,tg2 foreign key referencing the tg1's primary key,tg3 has primary k ey that tg2 and tg4 refers as foreign key,tg2 has foreign key referencing primar y key of tg4 ,the order in which the informatica will load the target? 2]How can I detect aggregate tranformation causing low performance? 374. How to Generate the Metadata Reports in Informatica? 375. How can we eliminate duplicate rows from flat file? 376. What is Partitioning ? where we can use Partition? wht is advantages?Is it nessisary? 377. In my source table 1000 rec's r there.I want to load 501 rec to 1000 rec into my Target table ? how can u do this ? 378. What is surrogatekey ? In ur project in which situation u has used ? exp lain with example ? 379. What is the diff b/w STOP & ABORT in INFORMATICA sess level ? 380.

n is looking on your computer. How do you do this. I have a person who uses my c omputer, and I think he is looking at sites he should not be viewing. 385. What is hash table informatica? 386. What are the properties should be notified when we connect the flat file source definition to relational database target definition? 387. How do you load the time dimension. 388. Can Informatica load heterogeneous targets from heterogeneous sources? 389. While running multiple session in parallel which loads data in the same table, throughput of each session becomes very less and almost same for each ses sion. How can we improve the performance (throughput) in such cases? 390. How do u check the source for the latest records that are to be loaded i nto the target. i.e i have loaded some records yesterday, today again the file h as been populated with some more records today, so how do i find the records pop ulated today. 391. What is the mapping for unit testing in Informatica, are there any other testings in Informatica, and how we will do them as a etl developer. how do the testing people will do testing are there any specific tools for testing 392. What are the mapings that we use for slowly changing dimension table?
