I have one question here with duplicates we can load in to VSAM? VSAm will take duplicates are not?
You can load VSAM file using a PS file which contains duplicate records but duplicates wont get loaded in KSDS file.
There is a parameter named ELIMIT which can control the number of "error records " REPRO will ignore. An error record can be a duplicate.
If the limit specified in ELIMIT is exceeded ( if number of duplicates are more than ELIMIT) then REPRO command will be terminate with an error.
