Is it possible in any way (native or using a specific product) to find out when was the last execution of a specific load module? Perhaps through a security audit (TSS in my case)?
The SMF data has executed programs, but it can be a pain to accumulate. Quite some time ago I developed a small system that updates a file with program execution information to make it easier to generate reports on the last time a given program executed. Check with your site support group -- they may have something to help you.
