The System Service Tools user IDs can be maintained through a number of interfaces, including Dedicated Service Tools (DST), System Service Tools (SST), and System i Navigator. In addition to these well-known resources, there’s also the Change Service Tools User ID (QSYCHGDS) API. The QSYCHGDS API allows you to both rename a service tools user ID and change its password.
Sometimes starting up DST or SST or even System i Navigator is simply too time consuming compared to the simple operation of changing a SST user ID password, so based on the QSYCHGDS API, I’ve written a Change Service Tools User ID (CHGSSTUSR) CL command that allows you to perform this type of user ID maintenance from a command line or a CL program. The QSYCHGDS API also comes in handy if you manage more systems and you need to change SST user IDs or passwords across all of those systems.
