Scaling of memory-related configuration settings for tests of DB2 LUW

In my recent post I wrote about some available workload drivers. Today, I would like to point you to an interesting article on developerWorks: Scaling of DB2 for Linux, UNIX, and Windows memory-related configuration parameters on a test system. In that article the authors describe a way of simulating a production system on a test system by scaling down (or up) some of the memory settings. They describe a constrained and a relaxed approach for either a system with fixed settings or one with flexible settings like when STMM is in use. A Perl script is provided so you can use the approach for your own testing.
