Answer / ankit kansal

Hi, if you know the number of duplicates coming your from source then it's easy to move the duplicates to the defined target using router transformation easily,
But if you do not know the number of duplicates then first you must sort the data on the value of duplicate column and then using Transaction Component as available in informatica you can create n no of targets depending upon the values encountered.

Answer / kiran kumar

hi
put the hash partition in active stage then
make three node configuration then u got the output

Answer / suneelbabu.etl

can u mention some more input records as well output

Answer / sher

something like below should work...

Job#1
Read in transformer to add a new column sequence the value of sequence will be initially 1 and increment when key changes…
so output(A) will look like…
1 1
1 1
2 2
2 2
3 3
4 4
B 5
under job sequence, use a job activity to read(A) use tail -1 and | cut to read 2nd column. we get 5..
Now, use start loop activity and end look activity stage in job sequence to create a loop from 1 to jobactivity.output incrementing by 1..
The look will now run 5 times.. inside the loop, call a job and pass the value i.e 1,2,3,4,5 each time it runs.
Inside the called job, read the input file(A) pass to transformer and then use constraint to write only records where 2nd column = variable passed and drop column 2..
Output of transformer.
1st loop output
1
1
2nd loop output
2
2
and so on...
when writing the file, use the passed variable in file name, so file name is distinct

Answer / narayan

just add the mod function like this =MOD(inputcol|3) and then load into different targets

Answer / sivakeshava

hi friends by seeing the source we need 3 targets....which id duplicates 1,1 is one target, and 2,2 is 2nd target and 3 is another target
Seqfile------------ >copy -------------- lookup(innerjoin) ------------- filter

Aggregator---------------- > filter
(count) where clause

copy to aggregate then filter to lookup then will give 3 targets

Answer / vaibhav

Actually it is like:
I want as many target links as much u have types of duplicates in my input file.. Pls help guys..
