How to send random values from a file?
Hi,
Can anyone tell us how to select random values from a file for
parametrization?
When we use the CSV data set config file the values are taking sequentially.
So can anyone tell how to proceed in this aspect.
Thanks,
Srinivasulu N

Generate a random number and read the file until that record is
reached. Of course this will need to be synchronzed, unless you use
different file connections per thread - which could cause resource
exhaustion with more than a few threads.
If all records are the same length you should be able to skip to the
appropriate record, which would obviously be quicker and would reduce
the synchronize time.
Randomising the file before use is a much better approach.

If the duplictes are allowed then how to access them...??

JMeter does not support random access to data files.
This would not be trivial to implement, and would be slow unless all
the lines in the file were the same length.
Also, what do you mean by random order? Are duplicates allowed, or can
each entry only be used once? If the latter, then JMeter would need to
keep track of which entries had been used.
Of course it would be possible, but I think this it would be out of
scope for JMeter.
==
In the past I've used the Perl Math module to generate the random
numbers, and then processed them as necessary to generate the actual
data.
Or generate a randomly ordered list of numbers and use that to process
the existing data into a random order.

Suppose if we have 10,000 data , could you tell me how to randomise this?
