Please clarify....

* LoadRunner Parameter name length?

* LoadRunner Parameter Data Length?

* < C | VB | Java | VB Script | JavaScript | C# > parameter name length|data length?

You may want to put some bounds around the follow up response, such as X virtual user type, with Y language and using either the native language variable declarations or the LoadRunner defined parameter model.    Also, if you have observed an odd condition related to a length condition you may want to explain your observations, your expected result and your actual result.

You should realize something is odd with your specification if you have exceeded the capabilities of Excel and Notepad.

You could use the file, assuming it has nine million rows.   Keep in mind that the file is going to be loaded into RAM at the beginning of the test.   This is by design and is there to minimize disc activity on the drive during the test.   OK, so now you have the phone book of a large city in RAM, your load generator is swapping like nuts because you are nearing the addressable limit of a 32 bit operating system at 4GB of RAM on the Box (and you only have 3GB on your load generator) and what are the nine millions rows buying you, specifically, in terms of load and performance?

Have you considered for names, as an example, if you need data spread, 512 first names, 26 middle initials and 512 last names picked randomly for each component provides for a distribution of 6,815,744 name combinations and uses a very small amount of RAM to do so.    Likewise, random generated street numbers, street names, valid zip codes from a file read random  (Ciry, State, Zip tied to line) provide for a very compact set of data with enormous complexity in terms of use.

As a performance tester|engineer we need to follow the same rules we expect of any other developer in terms of using the smallest amount of resource to get the job done, or you may wind up with 500 load generators to support 500 virtual users.   Not a very scaleable solution set.

Hi Pulley,

You are correct, I have explained all this my client and he is not understanding and blaming tool.

Thanks for your info.

Thanks,

Not a software tool issue, but a client "tool" issue. When someone who doesn't understand what you do and why you do it is directing what and how you can be absolutely certain of failure.

If your client hired you for expertise and is now ignoring it then they are a fool. Take the money, force them to sign off (actual signature) on every decision that you know will lead to catastrophic failure, and then cash the check before they challenge payment. A fool and their money are soon parted.
