LoadRunner Controller: Need to Split up Parameter File

Question

Background: We have a VuGen script we inherited that does exactly what we need. It uses a parameter file with all the data, i.e., some 30K+ rows. However, we need to run it across, say 10-20 virtual users, each with a share of those 30K rows. I'm new to LR so we're not sure how to set that up in the Controller. For example, do I need to split the input (parameter) file into, N different files and have N v-users run each of them? I'm just not sure how to set this up.

Thanks!

Answer 1

You are going to have memory issues as each user loads a copy of the data.

As you are new to LR, I will refer you to your training material regarding parameterization which includes a lab with just this very question, on unique distribution of data for users within a group

I would recommend moving the one file to Virtual Table Server OR a cloud-based queue solution OR RabbitMQ, then feeding all users off of the queue
