Using templates for operators provided in TPT - response (17) by vijaydf

i just noticed I am getting the below message in TPT.but the job is not aborting....
File_Reader: TPT19012 No files assigned to instance 6.  This instance will be inactive.
File_Reader: TPT19012 No files assigned to instance 5.  This instance will be inactive.
File_Reader: TPT19012 No files assigned to instance 3.  This instance will be inactive.
File_Reader: TPT19012 No files assigned to instance 2.  This instance will be inactive.
File_Reader: TPT19012 No files assigned to instance 4.  This instance will be inactive.
 
Why is that the 5 instance are inactive.  i have defined 6 Reader insttance. but why only one instance is active.
TO OPERATOR (File_Loader[3])
SELECT * FROM OPERATOR(File_Reader[6]);
 
Can you someone please help me in understanding. does is make any difference if i give File_Reader[1] & File_Reader[6]?
