Another big jump, but now it was my job to run benchmarks in the lab, and write white papers that explained the new products to the world, as they were launched. I was mostly coding in C, tuning FORTRAN, and when I needed to do a lot of data analysis of benchmark results used the S-PLUS statistics language, that is the predecessor to R.

When you list the HammerDB directory you can now see a directory called “scripts” This directory contains CLI scripts to build, run, delete and query TPROC-C and TPROC-H workloads against all databases. If HammerDB is running on a separate system from the database under test then you should modify this value accordingly.
