Indirect Method in Informatica


This can be handled by using the file list in informatica. If we have 5 files in different locations on the server and we need to load in to single target table. In session properties we need to change the file type as Indirect.
(Direct if the source file contains the source data. Choose Indirect if the source file contains a list of files.
When you select Indirect, the PowerCenter Server finds the file list then reads each listed file when it executes the session.)
am taking a notepad and giving following paths and file
names in this notepad and saving this notepad as
emp_source.txt in the directory /ftp_data/webrep/
/ftp_data/webrep/SrcFiles/abc.txt
/ftp_data/webrep/bcd.txt
/ftp_data/webrep/srcfilesforsessions/xyz.txt
/ftp_data/webrep/SrcFiles/uvw.txt
/ftp_data/webrep/pqr.txt
In session properties i give /ftp_data/webrep/ in the
directory path and file name as emp_source.txt and file type as Indirect.

  1. I think the admin of this website is genuinely working hard
    for his site, as here every material is quality based information.
